There are a surprising number of myths surrounding HVAC systems and services. It can be hard to keep track of what’s right and what’s not, especially if you’re new to the industry. In today’s post, we’ll highlight nine of the most common myths that your local HVAC company wants you to know about. From myths surrounding HVAC maintenance to frequent questions about the services offered by HVAC professionals, we’ll introduce you to them all.

Myth 1: It’s ok to change your filter annually.

Whether you think it’s true or you simply only remember to change your HVAC system’s filters once a year, and you’re hoping it’s true, annual filter changes are common. While it’s possible to change your filter yearly, your HVAC company will recommend filter cleaning and changes at least quarterly in most cases. If your home has many pets, for better results, changing your filter every month to get rid of the built-up dander and pet fur will be better for your HVAC system.

Myth 2: If it isn’t broken, don’t fix it.

Think about the type of maintenance you do on your cars, such as checking the wiper fluid, oil, tire pressure, and fuel top-ups. Think about how much it extends your vehicle’s condition and how you potentially avoid costly repairs by having a regular check-up at the mechanic’s. Your HVAC system also benefits from routine maintenance, such as filter replacements, refrigerant level checks, and duct cleaning. The more you look at your system, the quicker your HVAC company can identify early warning signs and repair them before issues become too severe.

Myth 3: Leaks are easy to find.

Many people assume it’s simple to spot whether your HVAC system is leaking because you’ll notice a puddle of water surrounding your unit. Still, even the most significant leaks can be quite tricky to locate. With HVAC systems, your unit may also be affected by air leaks, meaning there’s not as much cool or warm air circulating throughout your Charleston, SC, home as you’d like. Without some of the state-of-the-art equipment that an HVAC company uses to identify leaks, it can be virtually impossible to locate them, especially if the leak is within interior walls.

Myth 4: Duct tape is suitable for duct leaks.

Despite the name, duct tape is not the best way to temporarily fix a leaking or damaged piece of ductwork while you wait for your HVAC company to attend. There are foil pipe wraps and tapes specially designed for this purpose. Still, your HVAC company will often simply deter you from using the leaking equipment so that you avoid potentially making the issue worse before they can arrive. Likewise, duct tape should not be used to repair chimney flues or any other part of your HVAC system, especially if you put it in a place where the tape can melt and leave a potentially hazardous residue in its place.

Myth 5: Your thermostat is always accurate.

You may be under the impression that because you can detect changes in room temperature throughout your Charleston, SC, home, it means your thermostat is working fine. Your thermostat may be off by a few degrees or more, which can have a surprising effect on the efficiency of your HVAC system. If you believe you see incorrect thermostat readings, check with an HVAC company to locate the issue’s source.

Myth 6: Thermostat placement does not matter.

One of the reasons it’s best not to just rely on your thermostat when you want to heat or cool a space effectively is because you may find that your thermostat is incorrectly located and is offering incorrect temperature readings. Ideally, your thermostat should be out of direct sunlight, in a draft-free location, outside of the kitchen, and located on an interior wall to get the best results. If you think your thermostat needs to be moved, an HVAC company can most certainly arrange for this to happen.

Myth 7: HVAC is the most effective way to control the temperature.

There are, in fact, multiple factors your home should rely on to heat or cool your space most effectively. The right insulation, for example, will help to cut down on heating and cooling costs and put less pressure on your HVAC unit. While an HVAC unit may provide more immediate control over temperature, making sure the home is well-insulated, and you have the right windows installed will help towards making long-term energy efficiency an achievable goal.

Myth 8: Less time on, least energy used.

You may think that if you’ve only got your AC running for 5-10 minutes a day, that you’re using your unit most efficiently and it will require less attention from an HVAC company. However, this isn’t always the case. Hotter days will require your AC to be on longer, so it will naturally use a lot of energy. But it’s important to remember that the power-on cycle also uses up energy, so it can be more beneficial to run for an extended period than stop/start cycles throughout the day.

Myth 9: Bigger is always better.

As with many home appliances, bigger isn’t always better. While you might be tempted to buy the largest unit available for your space, it can be less efficient to do this. A large unit, for example, can be prone to short cycling since it will heat or cool too quickly. One downside of this is you’ll get lower energy efficiency, even if it’s a brand new unit. Oversized units can also struggle to remove humidity, and you may see inconsistent heating or cooling results.
