It isn’t uncommon for your air conditioner in Kirkwood, MO to overheat. An overheating AC isn’t always serious, but don’t ignore it. Here are things you can do when it overheats.

Check the Filters

Filters keep harmful particles out of your home and are a common cause of an overheating system. If the filters get dirty or clogged, they block airflow, which makes the system work harder. Professional HVAC technicians suggest inspecting and if needed, replacing the air filters every 90 days.

Clean the Condenser Coils

The condenser coils are the outside parts that remove the heat from the air before it enters a room. If they get clogged with dirt or grime, they won’t cool the air, and the unit will keep running. When this happens, turn off the power to the unit, and attempt to remove the dirt with a hose or coil cleaner. A technician will do this during a regular maintenance

Get the Refrigerant Refilled

The refrigerant is the liquid substance that cools the air when it passes over the coils. When the refrigerant is low, the system has to work harder, which eventually overheats the motor, and it won’t cool effectively.

Common signs of low refrigerant are an iced-over outside unit or a unit that doesn’t cool like it once did. However, you won’t be able to refill it yourself because only licensed HVAC technicians can buy refrigerant.

Replace the HVAC System

If you have an older HVAC system, it may overheat from age, so consider a replacement. The average HVAC unit lasts for over a decade, but it is ideal to replace them every 10 years or so.

An aged system typically won’t be able to cool as effectively, especially during hot weather that stresses the old components. New AC systems are more energy efficient, and they often have safety features to shut down the unit when it overheats.

These are common reasons your AC may overheat, but it could be other issues. Regular maintenance is the ideal way to prevent problems with your air conditioning. Contact us at C & G Heating and Cooling to schedule an appointment for any HVAC services you need in Kirkwood, MO.
