Your air conditioner is meant to cool down your home and keep it comfortable. But sometimes, your system doesn’t want to cooperate, blowing warm air around your space instead. Not only is this frustrating, but it also can leave many homeowners scratching their heads since it can be hard to diagnose the cause.
We’re no strangers to failing air conditioners at Champion AC & Plumbing. There are a few different issues that can cause your AC to stop blowing cold air, and each issue has a different solution. We’re here to share what can cause your cooling system to stop working properly, and how you can fix it.
Dirty Air Filter
A common reason for ACs blowing warm air is a dirty air filter filled with dust and debris. This prevents the airflow and circulation needed to produce your desired temperature, making your system work harder for it to cool off your home. Your air filter keeps grime from building up on your coils, so if they’re clogged, the coils can ice over, freezing your AC.
To fix this, clean or replace your air filter frequently. We recommend replacing your air filter every 2-3 months for the most efficient HVAC system. To clean the evaporator coils, you can use specialty coil-cleaning spray foam. Since the evaporator coils can be difficult to reach and pose a safety hazard, you can also call an HVAC professional on our team for an AC tune-up.
Fan Or Fan Motor
When your fan or fan motor doesn’t work properly, your air conditioner may blow out warm air. If your fan is running too slow or not at all, this does not allow for airflow and results in hot and muggy temperatures inside your home. This issue can also cause your evaporator coils to freeze.
To solve a fan or fan motor problem, check to see if the blades are damaged or out of place. If they are damaged, it’s time to call for a professional AC repair company to take a look at your fan. Fixing a fan is complicated and attempting to repair it at home could lead to further damage.
Control Board
If you have inspected your filter, evaporator coils and your fan motor and they all seem to be working properly, then it may be a problem with your electronic control board, or PCP. This monitors the incoming temperature with a compressor that turns off and on according to the desired temperature.
If it is not working properly, then the connection to your compressor will not send any power. This makes temperature regulation harder. Schedule an AC tune-up with our technicians so that your PCP can be repaired before further damage is caused.
Tripped Breaker
Your AC uses an outdoor and indoor unit to cool down your home. If the outdoor unit trips the circuit breaker, it won’t be able to release heat from the refrigerant that is sent to it. This can cause your AC to produce warm air indoors instead of cool air.
To check for a tripped circuit breaker, find the circuit breaker panel that your outdoor unit is connected to. If the circuit breaker is tripped, set it back to the “on” position and wait for your home to cool back down.
