Energy-Inefficient Bad Habits That Increase Your Utility Bills

Key Takeaways:

  • Small and negligible actions, like leaving windows and doors open while the AC is running, can greatly impact your utility bill.
  • When air vents are closed in unused rooms, it throws off balance and can increase energy usage.
  • Dirty air filters and clogged drains can cause your HVAC system to work harder, leading to higher energy bills.
  • Turning off the appliances and leaving your windows open can help you cut off on extra energy expenditures.

Habits that don’t look like they matter much can bring up your utility bills in a big way. When these bad habits accumulate to form energy inefficiency, not only do you end up paying more on your bills, but you’re also contributing to the global energy crisis. Sounds a bit too real? Trust us, we know – because fixing these habits can save you some major dough.

Carney & Son 72 Degrees are pioneers in energy-efficient HVAC. We want to share tips on breaking these habits and saving your wallet and the planet.

1. Leaving your AC or heating

On days when you rush out the door, it’s easy to forget to turn off your AC or heating. But leaving these running while you’re not even home is just a waste of energy (and money!). Get into the habit of turning off your AC or heating before leaving the house. And if you’re forgetful, invest in a programmable thermostat to automate the process.

2. Cranking up the AC or heating

We get it – those hot summer days or freezing winter nights call for maximum AC or heating. But before reaching for the highest setting, try using a fan or layering your clothing first. These minor adjustments can make a remarkable difference in energy usage (and your utility bill!).

To our clients, we suggest investing in energy-efficient HVAC systems. They obviously cost more upfront, but the long-term savings and decrease in energy usage will not leave you regretful.

3. Closing air vents

Ventilation is the crux of a functioning HVAC system. When air vents are closed in unused rooms, it throws off balance and can increase energy usage. In an attempt to get comfortable, you may be unknowingly driving up your energy bill. The air pressure may build up in the air ducts and be forced to work harder, leading to a spike in energy usage. An energy-efficient HVAC system will not experience this issue as severely. You can avoid it altogether by keeping all air vents open.

4. Not changing the air filter

We all are guilty of letting this one slide. Still, a clogged or dirty air filter can increase energy usage and decrease the efficiency of your HVAC system. When dirt and dust accumulate on the tiny fibers of the air filter, it restricts airflow and forces the system to work harder. The more power your system requires to cool or heat your home, the higher your energy bill.

5. Leaving windows open

No matter how much you’re tempted to leave your windows open, you must be aware of your schedule and how long the windows will be available. Especially during hot or cold months, it can throw off the temperature balance in your home and force the HVAC to work harder to regulate the temperature.

You can keep your curtains closed for summer afternoons to block out the sun’s rays. In the winter, consider investing in insulated curtains.

6. Using space heaters

Nothing can be more energy inefficient than using a space heater to heat one room in your house. It uses excess energy and can also be a fire hazard if left on for far too long. The most probable and energy-efficient solution is to invest in a programmable thermostat and adequately insulate your home. Or you could simply use a cozy blanket and some hot cocoa to keep warm.

7. Constant appliance usage

Leaving appliances on standby mode may seem innocent enough. Still, it can contribute to a large chunk of your energy bill. Such seemingly small things as leaving the TV on all day or not fully loading the dishwasher before running it can add up. Get in the habit of turning off and unplugging appliances when not in use. Where you can replace your existing devices with energy-efficient alternatives, we suggest you put reminders instead of splurging all that money.

8. Not properly maintaining HVAC and appliances

Proper maintenance can work wonders for any machine, be it your car or HVAC system. Neglecting regular maintenance check-ups can result in the machine using more energy and ultimately costing you more money. Ask yourself when was the last time you had your HVAC system cleaned—been a while? Better schedule that appointment now.

9. Forgetting to use fans

Do you automatically turn on the AC when your home starts feeling stuffy? Fans are a great alternative as they use significantly less energy.

Contrary to the popular belief that fans are only helpful in summer, you can also use them for ventilation during colder months, as long as you’re not dealing with freezing cold. An additional perk of fans is that they can also help circulate warm air during the winter if you have a heat source in the room.

10. Older appliances

The older your appliances get, the more energy inefficient they become. Consider upgrading to newer, energy-efficient appliances. Not only will they save some bucks on your utility bills, but they’ll also be better for the environment. While this tip may not relate to your HVAC system, it’s important to remember that all home appliances can contribute to energy efficiency (or lack thereof).

Ending Note:

So, break your bad energy-wasting habits today and start saving money on your utility bills. It’s easier than you think and can be much more fun, too – just ask our team about how we can help get you started! With winter just around the corner, there’s no better time to switch to being more energy-efficient. Conserving natural resources is vital for both the environment and your bank account – so let’s all do our part and work towards making 2022 the year of sustainable living.

8 Ways To Tell Your Ductless Ac System Needs A Repair

Key Takeaways:

  1. In recent years, ductless AC systems have been gaining popularity in commercial and residential settings.
  2. Ductless AC systems are more efficient than traditional HVAC systems. They can be installed in just a few hours by a trained professional.
  3. Ductless AC systems are quiet and easy to maintain.
  4. Calling a professional for regular maintenance and repair can help keep your ductless AC system running smoothly for years to come.

Ductless AC Systems are a godsend during the summertime. They keep our homes cool and comfortable without all the noise and hassle of traditional air conditioning systems. But what happens when your ductless ac unit goes on the fritz? Suddenly, you’re left sweltering in your own home! Before you break out the fans and start sleeping on the couch, take a moment to read this blog post.

Carney & Son 72 Degrees will discuss the importance of ductless air conditioning systems and why you must call a professional to repair them if they break down. We’ll also tell you some telltale signs that your system needs repair. Remember that these indications may vary depending on the brand and model of your system.

Suppose you’re unsure whether or not you need to call a technician. In that case, it is best to consult your user’s manual or contact the manufacturer. Keep cool this summer – read on!

Ductless AC System – In A Nutshell

Remember the times when central air conditioners were all the rage? Well, they’re not anymore. In recent years, ductless AC systems have been gaining popularity in commercial and residential settings. And it’s no wonder they are more energy-efficient than central AC. They can be installed without modifying your existing ductwork (if any). They provide targeted cooling (or heating) for specific areas in your home or office.

A ductless AC system has two components: an outdoor compressor/condenser unit and one or more indoor air handling units. The outdoor unit pumps refrigerant through a conduit into the indoor units, where it evaporates and absorbs heat from the indoors, thus cooling the air.

Suppose you have a ductless air conditioning system or are considering installing one. In that case, it’s important to know the cues that it may need repair. That way, you can fix it before it breaks down completely and leaves you without cooling (or heating) in the middle of a heat wave!

The Signs of Repair!

Here are ten signs that your ductless AC system needs repair:

1. The Outdoor Unit Is Making Strange Noises.

Suppose you notice that your AC’s outdoor unit is making strange noises, such as hissing, buzzing, or grinding. In that case, this could signify something is wrong. It could mean that your AC’s compressor is failing or something is caught in the fan blades. If you hear any strange/bad noises, it’s best to contact a professional for help.

2. The Outdoor Unit Is Leaking.

If you notice that your AC’s outdoor unit is leaking, this is definitely a sign that something is wrong, and repair is needed. It could signify a refrigerant leak or that the unit is overloaded and needs to be replaced. If you spot any water stains or leaks, make sure to call a professional immediately.

3. The Indoor Unit Is Blowing Warm Air.

If your indoor unit is giving you warm air, there is definitely something wrong with your air conditioning system. It could be a clear sign of a refrigerant leak, or it could mean that the compressor isn’t working properly. Either way, you’ll need to call a professional to look at your system and figure out the problem.

4. The AC Unit Is Making Strange Noises.

If your AC unit starts making strange noises, it’s a sign that something is wrong and repair is needed. The noise could be popping off from the compressor or indicate that the unit is overloaded and needs to be replaced. If you notice any strange noises, make sure to call a professional right away.

5. The AC Unit Isn’t Cooling the House Evenly.

If you witness that your AC unit isn’t cooling the house evenly, it could be a sign of a problem with the ductwork. It could also mean a refrigerant leak or that the unit is too small for the space. It’s trying to cool. If you come across this problem, call a professional immediately to take a look and figure out the best course of action.

6. Energy Bills Are Rising

If you catch that your energy bills are rising, it could signify that your AC unit is working harder than it should be. This could be because of multiple different issues, so it’s important to have a professional take a look. It may be something as small as a loose connection or something more serious like a refrigerant leak.

7. The Unit Is Leaking Water

If you notice water leaking from the AC unit, it’s time to call a professional. This usually indicates a bigger problem and should be addressed as soon as possible before it causes further damage.

8. The Thermostat Isn’t Working Properly

If the thermostat isn’t working properly, it could be a sign that the air conditioning system itself is on its last legs. That is especially true if your unit is an older model. Suppose you’ve tried troubleshooting the thermostat and can’t seem to get it to work correctly. In that case, it’s time to call a professional.

Ductless AC units are a smart option for homes and businesses alike. They’re energy efficient and can be easily installed without requiring ductwork.

However, like any other type of AC unit, they can have problems from time to time. If you observe any of the above indicators, you must call a professional immediately to fix the problem. Doing so will help ensure that your AC unit lasts many years.

Let’s Bust Some Ductless AC System Myths!

If you’re considering a ductless AC system for your home or business, you may have heard some myths about them. Here we’ve got the four most common myths and the truth behind each one.

Myth 1: Ductless AC systems are more expensive than traditional HVAC systems.

Truth: While the initial cost of a ductless AC system may be higher than that of a traditional HVAC system, they’re much cheaper to operate. This is because ductless AC systems are highly energy efficient and use less electricity. You’ll likely save 30% of electricity by replacing window AC units with a ductless system.

Myth 2: Ductless AC systems are difficult to install.

Truth: Ductless AC systems are actually quite easy to install. In most cases, they can be installed by a trained professional in just a few hours.

Myth 3: Ductless AC systems are noisy.

Truth: Ductless air conditioning systems are actually relatively quiet. The compressor is located outside, so you won’t hear it running inside your home or business.

Myth 4: Ductless AC systems are difficult to repair.

Truth: Ductless AC system repairs are actually quite easy. The filters can be easily accessed and replaced, and the coils can be cleaned with a soft brush.

5 Signs Indicating That You Need Duct Cleaning& How To Do It

Key Takeaways:

  1. HVAC professionals recommend duct cleaning as part of regular maintenance.
  2. A few signs indicate it’s time for a cleaning, such as excessive dust buildup, unusual smells, or increased allergens in the home.
  3. The benefits include improved indoor air quality, fire prevention, and reduced energy costs.
  4. The duct must be cleaned every few years to keep your home safe and comfortable.

For many people, home cleaning means tackling their home’s dusty corners and cleaning the windows. But duct cleaning is often overlooked.

Your ductwork circulates air throughout your house; over time, it can become filled with dust, pollen, and other allergens. This can not only make it harder for your HVAC system to do its job, but it can also impact your family’s health. Cleaning the ducts removes built-up dirt and debris and improves the efficiency of your system.

This blog post will look at the signs indicating that you need duct cleaning, the benefits of getting it done, and preparing for it!

Signs Your House Needs Duct Cleaning

While you may not need to have your ducts cleaned every year, it’s crucial to keep an eye on them & have them cleaned when necessary.

Look out for the following signs!

1. You Can See Visible Mold Growth on The Ductwork

Mold is dangerous to your health and should be removed immediately. If you see visible mold growth on the ductwork, it’s time to call in a professional for cleaning.

2. The Ductwork Is Infested with Pests

If you see evidence of pests in the ductwork, such as rodents or insects, it’s time to have the ducts cleaned. Pest infestation may contaminate the air with disease-causing bacteria.

3. It’s Clogged with Dust & Debris

If the ductwork is clogged, it won’t be able to circulate air properly. This leads to decreased efficiency & increased utility bills.

4. You Can Hear Sounds Coming from the Ductwork

If you hear strange noises from the ductwork, it’s probably due to a blockage. Professional duct cleaners can remove the blockage and quiet the noise.

5. Musty Smell Coming from the Vents

If the ductwork has a musty smell, it could be due to mold or mildew. This is a severe problem that should be addressed by a professional.

Benefits of Duct Cleaning

1. Extends the Life & Improves Efficiency of your HVAC System

Regular cleaning can help extend the life of your system & improves the efficiency of your system by removing harmful contaminants that can cause corrosion and other damage.

2. Improves the Quality of Air

If someone at your house suffers from allergies or asthma, they may benefit from improved air quality. Cleaning can also remove musty odors from your home that may be caused by mold or other contaminants.

3. Prevent Fires from Starting in Your Home

An essential benefit of having your ducts cleaned is fire prevention. Lint and other debris can accumulate in your ductwork over time, and if it isn’t removed, it could create a severe fire hazard.

4. Reduces Energy Costs

When your HVAC system runs smoothly, it doesn’t have to work as hard to maintain a comfortable temperature in your home.

How Often Should Your Ducts Be Cleaned?

Most people don’t think about their ducts until there’s a problem. But since ductwork is an integral part of your home’s HVAC system, you should clean it regularly.

Depending on your home’s size & the number of visitors, you may need to have your ducts cleaned as often as once a year or as infrequently as every five years.

How Much Does It Cost?

If you’re thinking about duct cleaning costs, here’s your answer!

Prices can range from $0.20 to $0.40 per square foot, depending on the size and condition of your ducts. But this is just an average! The actual prices may vary depending on your situation.

How to Know If You’re Getting a Good Deal?

How to know if you’re getting a good deal? Here are a few things to consider!

  • First, ask for a quote. Any company should be able to estimate how much it will cost to clean your air ducts.
  • Second, compare prices and see which is the most affordable.
  • Finally, don’t forget to ask about discounts or promotions that may be available. Many companies offer specials or deals on air cleaning services, so it’s always worth asking about them.

These tips will help you get the best price on air duct cleaning services. And that’s something everyone can appreciate.

Preparing for Your Duct Cleaning Appointment

1. Clear the Area Around Your Vents and Registers

To clean your ducts effectively, professionals will need access to all of them. Make sure to clear any furniture or other items blocking the vents and registers in your home. You may also want to remove any decorative covers from the vents so you can clean them separately.

2. Clean or Replace Your Air Filters

You should clean or replace your air filters at least once every three months, but doing so before your duct cleaning appointment can help the professionals do their job more effectively.

3. Schedule Your Duct Cleaning Appointment for a Time When You’ll Be Home

It’s best to be home when the professionals arrive to clean your ducts so you can answer any questions they may have. You should also be available to point out any areas of concern that you want them to focus on.

Preparing for your duct cleaning appointment doesn’t have to be a hassle. You need to take a few steps to ensure the process goes smoothly!


That’s all there is to it! Here are a few tips for your duct cleaning appointment for a smooth cleaning process. Cleaning is vital to maintaining a healthy and efficient HVAC system. By preparing for your appointment, you can help the professionals do their job more effectively.

6 HVAC Mistakes That Are Costing You Money – DAILY!

Key Takeaways:

  • You might not know it, but the way you are running your HVAC system could be costing you money unnecessarily.
  • From not using a programmable system to not using a proper and clean air filter, there are many ways you could be throwing away your hard-earned cash.
  • It’s best to consult with an HVAC professional to get the most accurate and up-to-date information and amazing services.

Fall is around the corner, but the temperatures are still hot outside. You’re not the only one keeping your air conditioner on during the day. Many individuals put off cooling their houses until the last minute, which can result in costly mistakes. In this blog post, Carney & Son 72 Degrees will share some of the most common HVAC mistakes people make and how they can cost them money. We’ll also provide tips on how to avoid these mistakes and keep your home cool all summer long!

What is an HVAC?

HVAC is also referred to as Heating, Ventilation, and Air Conditioning. It is a mechanism for regulating a space’s humidity and temperature. A furnace, heat pump, or air-conditioner can do this. Both residential and business buildings employ HVAC systems.

HVAC Mistakes that are Costing You Money:

Your home’s HVAC system is in charge of maintaining your comfort all year long. However, if your HVAC system is not properly maintained, it can lead to some costly mistakes. Let’s examine some of the most common HVAC mistakes that are costing you money.

Mistake 01: Not using the programmable thermostat

More HVAC systems now have programmable thermostats that let you control the temperature of your house and individual rooms at various times of the day. You’re wasting money on utility expenditures if you leave your thermostat set at the same temperature throughout the day and night. Your device is operating when it shouldn’t.

Instead of maintaining a constant temperature across the whole house, set your thermostats to create a pleasant environment in the rooms where you will be spending most of your time.

Mistake 02: Using the programmable thermostat incorrectly

Knowing how to use a programmable thermostat most efficiently may save you a lot of money on your energy bills. Many people set their thermostats too high in the summer and too low in the winter. This causes your HVAC system to work harder than necessary, which wastes energy and raises your utility bills.

The key to correctly using a programmable thermostat is finding the right balance between comfort and efficiency. You should set your thermostat to the temperature you can tolerate in the summer and winter. Then, you can use the programming features to set your thermostat to adjust the temperature automatically throughout the day.

Mistake 03: Not changing the HVAC air filter

The air filter is one of the main parts of your air conditioner and heating/cooling system. When you don’t clean, check, or replace your filters when necessary, they frequently cost you money in pricey repairs.

Air does not pass through your air filter correctly when it is not clean. This is particularly true in regions like James Island, where there is sometimes heavy pollen or dust in the air.

The entire AC unit uses more power when the filter isn’t functioning properly. This puts additional strain on the appliance itself and raises your power costs.

To ensure that your filter is operating effectively and not costing you more money, schedule frequent inspections of the complete unit at least once every six months. Regular checks are simple to perform when you schedule a seasonal maintenance inspection in advance with your knowledgeable neighborhood HVAC specialists.

Mistake 04: Neglecting the outside units

Your HVAC system consists of two units, one inside and one outside. You may not often think about the outdoor unit, but it needs regular care and attention, just like the indoor unit.

Forgetting about the outside unit when doing routine maintenance can be a big mistake. The coils can become dirty, which will reduce the efficiency of your HVAC system. In extreme cases, a dirty coil can cause the unit to fail.

To avoid this costly mistake, have your HVAC specialist clean the outside unit coils at least once a year. It’s also important to keep the area free of debris and leaves around the outdoor unit.

Mistake 05: Choosing the wrong MERV rating

The Minimum Efficiency Reporting Value (MERV) test determines how well your air filter removes impurities and pollutants from the air. The higher the rating, the better the filter performs at eliminating contaminants to enhance overall air quality. A filter with the highest MERV rating may not be the best option for your house. Since they are frequently thicker and more restricting, HVAC systems must expend more energy to circulate air and control temperature.

To maintain a healthy level of air quality and eliminate typical pollutants and toxins, filters with a MERV rating of 5-8 should function well in your home. We advise using a filter with a MERV rating of 9 and 12 if you or a family member has allergies or other respiratory conditions.

Mistake 06: Skipping routine maintenance

We’ve said it before, and we’ll say it again: inspections and preventative maintenance are cost-effective. By spotting problems early, you can ensure that your HVAC system is constantly operating effectively and at its maximum potential.

While some HVAC problems are immediately clear, others might only be apparent to a qualified expert. Get a professional to check on your HVAC system at least twice a year (spring and fall are good times). This will help ensure that any potential issues are rectified before a problem escalates and necessitates the complete replacement of your equipment.

The HVAC system plays an important role in your home, so don’t let HVAC mistakes cost you money – get your unit checked out regularly!

6 Reasons To Get Your Air Conditioner Serviced Through The Seasons!

Summer is in full swing, & with the soaring temperatures comes an onslaught of Air Conditioner advertisements. This got us thinking- how often should you get your home’s air conditioner serviced? There are so many conflicting opinions; our experts at Carney & Son 72 Degrees thought it would be helpful to lay out a few reasons why getting your AC serviced regularly is a good idea.

Here are 6 reasons to get your home’s air conditioner serviced regularly. Stay cool!

Reasons Your Home’s AC Regular Service Is Important?

1. It Improves Air Quality

We all get how crucial it is to breathe clean air. Unfortunately, the same can’t be said about the air inside our homes. The EPA widely states that indoor air quality can be up to five times worse than outdoor air quality. One of the primary reasons for this is that most homes are not properly ventilated.

This means that all the pollutants and contaminants produced inside your home (from cooking, cleaning, smoking, etc.) get trapped inside. Over time, these pesky pollutants can build up and cause serious health problems.

2. It Prevents Allergies And Asthma

Suppose you or someone in your family suffers from allergies or asthma. In that case, ensuring that your air conditioner is serviced regularly is especially important. This is because AC units have filters that can remove many allergens and pollutants in the air. Regularly changing these filters can significantly reduce the number of allergens in your home, making it a much safer place for everyone.

3. It Keeps Your Home Cool And Comfortable

During the summer months, there’s nothing worse than coming home to a stuffy, hot house. Not only is it discomfiting, but it can also be dangerous for young children and elderly people. Having your AC unit serviced regularly can avoid this problem and keep your home cool and comfortable all summer.

4. It Can Save You Bucks On Energy Bills

If your AC unit isn’t running efficiently, it will use more energy to cool your home. This means higher energy bills for you each month. Having your AC serviced regularly can help ensure that it’s running as efficiently as possible, saving you significant money over time.

5. It Helps In Boosting The Life Of Your AC Unit

Like any other appliance in your home, your air conditioner will eventually need to be replaced. However, regular servicing can help extend your AC unit’s life and prevent it from breaking down prematurely.

6. It Downsizes The Risk Of Carbon Monoxide Poisoning

If your AC unit isn’t serviced regularly, there is a risk of carbon monoxide leaks. Carbon monoxide is known to be a colorless & odorless gas that can be deadly if inhaled. Having your AC serviced regularly will help to reduce the risk of carbon monoxide poisoning in your home.

The Bottom Line

Regular AC servicing is important for several reasons. It helps to keep your home cool and comfortable, can save you money on your energy & utility bills, and can significantly extend the life of your AC unit. If you’re not already getting your AC regularly serviced, be sure to start doing so today!

‘Why Is My Mini-Split Leaking Water?’ & Other Ductless Air-Con Issues!

Ductless air-conditioning, or mini-splits, is becoming more and more popular. They’re efficient, quiet, and can be installed almost anywhere. But like any other piece of machinery, they’re not perfect. If you’re having issues with your mini-split, you’re not alone.

This blog post by Carney & Son 72 Degrees will explore some of the most common ductless AC problems and their solutions. Stay cool!

Issue #01: My Mini-Split is Leaking Water

If your mini-split leaks water, it’s likely due to one of two issues: either the drain pan is full, or the condensate pump is not working properly.


1: Empty the Drain Pan

The first thing you’ll want to do is check the drain pan. If it’s full, empty it and see if that solves the problem. If your mini-split doesn’t have a drain pan, you can purchase one at your local hardware store.

2: Check the Condensate Pump

If your mini-split has a condensate pump, ensure it’s turned on and working properly. If it’s not, you may need to replace it.

Issue #02: My Mini-Split is Making Strange Noises

If your mini-split is making strange noises, it could be due to several issues, including loose parts, debris in the fan, or a problem with the compressor.


1: Check for Loose Parts

First, make sure all the bolts and screws are tight. If that doesn’t solve the problem, you may need to call a technician to take a look.

2: Clean the Fan

If your mini-split fan is dirty or full of debris, it can cause strange noises. To clean the fan, turn off the power and remove the unit’s front panel. Then, use a brush or vacuum attachment to remove any dirt or debris.

3: Call a Technician

If you’ve tried the above solutions and the noise persists, there’s likely an issue with the compressor. In this case, you’ll need to call a technician for repairs.

Issue #03: My Mini-Split is Blowing Hot Air

If your mini-split is blowing hot air, it could be due to several mini-split issues, including clogged filters, a refrigerant leak, or a problem with the thermostat.


1: Check the Filters

If your mini-split filters are dirty or clogged, they can restrict airflow and cause the unit to blow hot air. To clean the filters, remove them from the unit and wash them with soap and water.

2: Check for a Refrigerant Leak

If your mini-split is leaking refrigerant, it will likely be blowing hot air. To check for a leak, look for an ice buildup around the copper lines that connect the indoor and outdoor units. If you see ice, there’s likely a refrigerant leak.

3: Check the Thermostat Settings

If your mini-split thermostat is too low, it may be blowing hot air. To check the thermostat settings, look for a switch near the indoor unit that says “Fan” or “Auto.” If the switch is set to “Fan,” change it to “Auto.” If the problem persists, call a technician for help.

Important Note: You can try these fixes at home but don’t go overboard. You may end up doing more harm than good. It’s best to call a professional after a few tries!

Beating The Heat – 9 Fascinating Facts About Air Conditioners!

There’s nothing as refreshing in the summer as a cold drink or an ice cream. And when the weather is really hot, what’s better than stepping into a nice, cool room?

Air conditioners help make summer temperatures more bearable and are necessary for many homes. But how extensively do you know about air conditioners?

Here are some fascinating air conditioner facts about these cool appliances by Carney & Son 72 Degrees.

Cool Facts About AC

  1. The first air conditioner wasn’t designed for comfort: They were first used in the 1800s to help prevent the spread of disease. The first air conditioner was designed by a doctor, John Gorrie, who wanted to find a way to cool patients with malaria.
  2. Movie theaters used to be the coolest: Air conditioning was first installed in movie theaters in the early 1900s. Inventors did this to help keep the film from melting in the heat!
  3. Air conditioners can save your life: Studies have shown that air conditioners can help reduce the risk of heat-related deaths during a heatwave.
  4. An AC unit uses a lot of energy: A typical central air conditioner will use 3000 to 5000 watts of electricity to run. That’s about as much as it takes to power a clothes dryer!
  5. There’s a right and wrong way to use your AC: Running your air conditioner all day long is bad for your energy bill and health.
  6. They can cause mold: If your air conditioner is not properly maintained, it can become a breeding ground for mold and mildew.
  7. They can make you sick: If you are allergic to dust or mold, you may want to reconsider using an air conditioner.
  8. They can cause global warming: Chlorofluorocarbons (CFCs) are used as a coolant in many air conditioners. When these chemicals are emitted into the atmosphere, they deplete the ozone layer, which leads to global warming.
  9. It’s best to clean your air conditioner regularly: To keep it running efficiently, it’s important to clean it regularly. Depending on your home’s air conditioner, you may need to do this yourself or hire a professional.

Is AC Maintenance a DIY Job?

In a nutshell, no, AC maintenance is not a do-it-yourself job. While you can certainly clean the filter independently, other tasks, like checking and refilling refrigerant levels, require professional training and equipment. Additionally, many newer AC units have sealed systems that prevent homeowners from accessing internal components. Trying to repair or maintain these units alone could void the warranty.

5 Environmentally Friendly Refrigerants For Using HVACs Responsibly

It’s no secret that harmful refrigerants have devastatingly affected the environment. Many businesses are now looking for environmentally friendly refrigerants to replace Freon and other harmful chemicals.

In this blog post, Carney & Son 72 Degrees will discuss some of the best environmentally friendly refrigerants on the market and how you can use them in your HVAC system responsibly!

History Of Harmful Refrigerant Effects On The Environment:

Chlorofluorocarbons, CFCs or Freon, are a group of man-made chemicals that were once commonly used in refrigerators, air conditioners, and aerosol cans. However, freons were found to damage the Earth’s ozone layer, protecting us from harmful ultraviolet rays. As a result of this discovery, the production of CFCs was banned in many countries in the late 20th century.

Hydrofluorocarbons (HFCs) or another brand of freons are a group of man-made chemicals developed to replace CFCs. While HFCs do not destroy or harm the ozone layer, they are potent greenhouse gases that trap heat in the Earth’s atmosphere and contribute to global warming.

Global Warming Potential (GWP) tool:

In response to the toxic effect, a timeline for the phase-out of chlorine-based refrigerants was established by the 1987 Montreal Protocol and subsequent accords. The Global Warming Potential (GWP) tool was created to gauge and compare how refrigerants and other compounds affect the atmosphere and consequent global warming. Rating refrigerants according to their GWP values enables harmful gases with high GWP values to be phased out while promoting those with lower GWP values as replacements.

5 Environmentally Friendly Refrigerants:

Fortunately, several environmentally friendly refrigerants can be used in place of CFCs and HFCs. These refrigerants include:

1. Hydro-fluoro olefins (HFOs):

HFOs are a type of fluorocarbon, but they do not contain chlorine or bromine and are therefore much less damaging to the environment.

Few of the HFOs include R449A and R454C.

2. Carbon dioxide (CO₂):

CO₂ is a naturally occurring gas used as a refrigerant for many years. It is non-toxic and does not contribute to ozone depletion. CO₂ is a very efficient refrigerant, but it can only be used in applications where the temperature is below 78 degrees Fahrenheit.

3. Ammonia (NH₃):

Ammonia has been a refrigerant for over 100 years and is still used today. It is very efficient and has a very low impact on the environment. Ammonia is also very inexpensive, making it a great choice for businesses looking to save money.

However, its flammability limits its widespread use.

4. Isobutane (C₄H₁₀):

Isobutane, which is stable and comparable to its predecessors in performance and environmental effect, has a very low GWP value of just 3. It is now among the most regularly used refrigerants for residential, commercial, and industrial refrigeration.

5. Isopropane:

Isopropane is evolving into a common refrigerant for commercial and industrial refrigeration and specialized applications for camping, recreational vehicles, laboratory, and medical refrigeration. It combines Isobutane and well-known, affordable, and easily accessible propane.

Several other refrigerants have low GWP values and are considered environmentally friendly. However, the two most common ones are Isobutane and isopropane. These are two great options to consider if you’re looking for a refrigerant that will not harm the environment.

Can Anyone Actually Use A Heat Pump In Summer?

A heat pump might be ideal if you’re looking for an energy-efficient way to keep your home cool during the summer. Heat pumps can be used in winter and summer, making them a versatile option for homeowners. You need to know certain things before you decide if a heat pump is right for you. This post will discuss in detail what you should know about using a heat pump in summer!

Using a Heat Pump in Summer – How Does it Work?

As the weather gets warmer, you might wonder if you can use a heat pump in summer. The answer is yes! Heat pumps can efficiently cool your home in the summer months. Here’s how it works:

It extracts heat from the air inside your home and transfers it outside. This procedure cools the air inside your home and makes it more comfortable.

Save Money with a Heat Pump in Summer

One benefit of a heat pump is that it doesn’t use as much energy as other cooling methods, such as central air conditioning. You can save a huge amount on your energy bills during summer.

In addition to saving money, using a heat pump in summer can also help improve the indoor air quality of your home. By circulating the air, the heat pump can remove pollen, dust, and other allergens from the air. This can reduce the symptoms of allergies and asthma.

Remember a Few Things

If you’re considering using a heat pump in summer, there are a few things to remember. First, it’s important to have your heat pump serviced before the start of the season. This will ensure that it’s working properly and that there are no potential problems.

Second, you’ll need to ensure that your home’s heat pump is the right size. If it’s too small, it won’t be able to cool your home effectively. However, if it’s too large, it will use more energy than necessary, increasing your utility bills.

Third, you’ll need to ensure that your heat pump is properly installed. If it’s not, it could cause problems with cooling your home.

Finally, ensure that you maintain your heat pump properly. This includes regularly changing the filters and ensuring that the coils are clean.

Using a Heat Pump in Your Bedroom

  • First, you’ll want to ensure that you keep the blinds or curtains closed during the daytime. This will help keep the sun out of the room and make it cooler.
  • You may also want to consider using a ceiling fan in your bedroom. That will circulate the air and keep the room cool.
  • Using it for a couple of hours when you go to bed will help cool down the room so that you can sleep comfortably.

4 Common AC Maintenance Mistakes Homeowners Make

Air conditioning units are a considerable investment, but the relief they offer from the blistering summer heat makes them worth the investment. However, it is essential to take care of your unit. You can expect about 20 years of use from your unit with regular air conditioner maintenance.

Unfortunately, many homeowners make mistakes with air conditioner maintenance that can lead to decreased efficiency and a shorter lifespan for their air conditioning unit.

To help you out, below are the four common air conditioner maintenance mistakes highlighted by HVAC contractors. By avoiding these, you can keep your air conditioner running without issue for years to come.

Ignoring Unusual Noises:

After spending a specific time with your air conditioning unit, you’ll become familiar with its normal operating noises. In many cases, unusual noises are an indication of a more severe issue developing within your air conditioner. For instance, shrieking noises may indicate that your air conditioner’s compressor is failing, while rattling noises may be a sign that something has come loose inside the unit.

If you ignore these noises and continue to run your air conditioner, you could end up causing severe damage to the unit – and incurring expensive repair bills as a result.

Not Changing the Air Filter:

Air conditioner maintenance isn’t just about the coils and fins outside the unit. You should regularly change the air filter. It tracks dust, pollen, and other particles that can clog the system. A dirty air filter will make your unit work harder than necessary, eventually leading to a complete system shutdown.

The rule of thumb is to change it every three months but check it monthly to be certain. All you have to do is remove the old filter and put a new one in its place. However, be careful with the sizing.

Failing to Repair Leaks:

Leaks are a prevalent problem with air conditioners. It could be a slow drip or a full-on gush, but you need to take care of it. The Freon gas that cools the air can be expensive, so you don’t want it leaking out.

Contact professional HVAC contractors immediately if you see any signs of a leak, such as a pool of water around the unit. They will be able to repair the leak and recharge your system. Please don’t attempt this yourself as you could worsen the problem.

Putting Regular Maintenance on the Backburner

Installing an air conditioner is just the beginning. You must also commit to regular air conditioning maintenance for your unit to work properly and efficiently. Examining thermostats, cleaning the condensate pump of any algae build-up, and ensuring the outdoor compressor is free of debris are all part of regular maintenance.

If you neglect these things, your air conditioner will have to work harder to do its job. It could eventually cost you more money in the long run. HVAC contractors can help you keep on top of regular maintenance so that you don’t have to worry about it.


Air conditioners are a sigh of relief during the hot days of summer. However, they can be a headache when they break down and need repair. Before you hose down your ducts in the hope of fixing the problem, take a step back.
