Is your central air conditioning system not working like it used to? Knowing a little bit about your
air conditioning system at home will help you troubleshoot the problem and determine if you
need the help of an HVAC professional.
Here are some common problems you might encounter with your central air conditioning system
at home and their possible solutions.
Air Conditioning Will Not Turn On
The most likely reason for the air conditioning system not activating is a tripped circuit breaker
or a faulty thermostat. Some possible solutions are:
● Make sure the thermostat is set to cool, not off or heat.
● Set the thermostat below current room temperature.
● Check that the circuit breaker controlling the air conditioning is in the “on” position. If the
circuit breaker has tripped or the fuse has blown, you’ll need to reset the circuit breaker
and replace the fuse. If they trip or blow again after reset, you should call a technician as
soon as possible, as you may have a more serious problem at hand.
Poor Airflow From The Vents
Low airflow is usually caused by accumulated dirt in the air filters or ducts. Some possible
● Confirm that the air filter is clean. If not, clean or replace the filter.
● Inspect all ductwork to ensure they did not disconnect, including in the harder-to-reach
places like the attic, basement and crawl spaces. You can contact a professional to
repair or reconnect ductwork as needed.
Air Conditioner Does Not Dehumidify Air
The size of the air conditioning system can affect its ability to remove humidity in the house. For
example, a system that is too large for space will cool the air too quickly, meaning that the
thermostat shuts off before all of the humid air makes its way through the cooling coils for
dehumidification. You’ll also notice that your system turns on and off frequently if it’s oversized.
The only solution here is to replace the condensing unit and coils with an appropriate size. You
can also try increasing the cooling load by extending the system to other spaces, such as the
garage or basement, with additional ductwork.
Inadequate Cooling Plus A Long Compressor Cycle
This is a sign of a worn-out compressor that has not been able to compress the refrigerant
effectively. The compressor is usually located in the outdoor housing unit. If you hear it running
constantly, but there still isn’t enough cool air in the house, then you know you have a problem.
An HVAC professional can help you test and replace the compressor.
