7 Signs It Is Time To Call An HVAC Company | Charleston, SC


The HVAC system in your Charleston, SC home is essential to your daily life. If it isn’t functioning properly, your home will be very uncomfortable. You rely on your HVAC system to keep your home warm during the winter and cool during the summer. The last thing you want is a complete HVAC system breakdown when you need it the most. The best way to prevent a complete breakdown is to recognize the early signs that you need to call an HVAC company. If you can detect the signs early, you can prevent a minor issue from becoming a major one.

#1 The System Isn’t Producing Cool or Heated Air

This is the most obvious sign that you need to call an HVAC company, and it should not be ignored. Before you make the call, turn your system on full blast and stand under the vents. If you feel cool or heated air, you are all set.

If the temperature in your home doesn’t change after a few minutes, you will need to call a licensed company. There are a few issues that could be causing the problem:

  • A leak in the refrigerant line
  • A malfunctioning compressor
  • A short in the electrical connections

It is best to call an HVAC company right away to prevent the issue from getting worse.

#2 Insufficient Airflow

If you aren’t getting adequate airflow from the vents in your home, your home won’t reach the desired temperature. Your system will try by working overtime, which can cause an increase in your energy bills. It can also reduce your HVAC system’s lifespan.

There are a couple of issues that can cause poor airflow:

  • A broken motor
  • Clogged air filter
  • Clogged air ducts

It is essential that you call an AC company as soon as you realize that you have inadequate airflow.

#3 Strange Sounds Coming From the Unit

When your HVAC system is functioning properly, you shouldn’t hear anything more than a quiet clicking when the system kicks on and off. If you hear anything more, such as squealing, squeaking, grinding, or any other strange sounds, you should call an HVAC company. There could be a broken or loose part rattling around in the system, which can cause further damage. Even if your HVAC system is still functioning properly, you should still schedule an appointment with an HVAC service right away.

#4 Frequent Cycling

It is normal for the HVAC system in your Charleston, SC home to cycle frequently. When it is very hot or very cold outside, it will cycle more often; however, it should not cycle constantly. If you notice frequent cycling, you should schedule an appointment with an HVAC service right away.

The issue could be that your system needs a tune-up, which is a relatively simple fix. This could also be a sign that your HVAC system has reached the end of its lifespan and needs to be replaced.

It would take the knowledge and experience of an HVAC company to determine the source of the problem to resolve the issue accordingly.

#5 Foul Odors Coming From the HVAC System

If the air coming from the vents in your Charleston, SC home smells musty or moldy, you should schedule an appointment with an HVAC company. This can be due to mold build-up in the air ducts or in the HVAC system itself. This is a very serious issue. It is very dangerous for your family to breathe in mold spores. This can cause allergy symptoms. If a member of your family has a chronic respiratory illness, breathing in mold spores can make their condition worse.

An HVAC company can find the location of the mold and remove it.

If you smell a burning smell, you should turn your HVAC system off immediately and call an HVAC service. There could be an electrical short that can cause a devastating electrical fire.

#6 A Frozen Or Leaking Unit

If there are any leaks, puddles, or ice around your HVAC system, you should call an HVAC professional immediately. The issue could be a block in the condensation line, causing the condensation to freeze on the coils. When the ice melts, it will puddle around the ground.

You could also have a refrigerant leak, which will affect the way your system performs.

It is best to call an HVAC professional as soon as you notice the problem.

#7 Energy Bills That Are Higher Than Normal

If you notice that your energy bills are higher than normal, your HVAC system could be to blame. If your system isn’t operating as efficiently as possible, it will need to work overtime to keep your home comfortable.

This issue could require a tune-up, which is a relatively simple fix. It could also be an issue with the mechanical components, or the system may have reached its maximum lifespan.

You will need the assistance of an HVAC company to figure out what is causing the problem so the issue can be resolved.
