The heat is on in Florida and now is the time to make sure your air conditioner is working properly! July is the hottest month of the year, so before the heat is in full force, you’ll want to get the pros out to your house to address any common AC problems you might be having.

You can avoid many problems with preventative maintenance each fall and spring, but if you notice any of the following issues, it’s time to call for maintenance.

1. Strange Sounds

You can typically hear your air conditioning unit kick on and you might hear some airflow, but the sounds aren’t usually loud or odd. If you hear strange sounds, like a grinding, grating, or squealing noise, there is probably something wrong.

If you hear strange sounds, call an HVAC professional. It might be a small fix that prevents large repairs down the road.

2. Strange Smells

Your air conditioner shouldn’t be emitting any smells, so if you smell something strange, it likely indicates a problem. A rotten egg smell could be the result of a natural gas leak, which can be dangerous if left unattended.

An electrical or burning smell could be the result of the motor or other electrical equipment overheating. An electrical fire could cause a lot of damage.

Finally, a musty smell could be the result of mold or moisture build-up in the ducts. If the ducts are clogged, moisture collects and causes mold and mildew.

3. Reduced Air Flow

Low or weak airflow could be the result of a number of different issues. The simplest one is a dirty or clogged air filter. Change your air filter regularly especially if the air conditioning runs often.

It could also be due to air ducts that aren’t properly sealed or cleaned or a compressor failure. These issues will need to be handled by the pros and can often be avoided by routine maintenance.

4. Air Isn’t Cold

If your unit is blowing air that isn’t cold, it could be a problem with the thermostat or the result if a refrigerant leak. If the air isn’t cold and rooms aren’t being cooled, check the thermostat to make sure it is working properly and set on the correct temperature.

If everything is working with your thermostat, you might have a refrigerant leak that will need to be addressed by an HVAC professional.

5. It’s Old

Unfortunately, air conditioners don’t last forever. The average age of an air conditioning unit is about 10-15 years. That is impacted by how often it’s used too, which is especially relevant in a warm-weather state like Florida.

If your AC is up there in years, it might be time to consider replacing it before it goes out completely in the dead of summer.

Common AC Problems You Shouldn’t Ignore

Many common AC problems can be avoided if you service your unit regularly. Even still, problems happen. It’s necessary to call professional HVAC technicians to handle the problems described above.
