Air conditioner not cooling
To diagnose or correct air conditioning problems such as reduced air conditioner cooling capacity or a system that simply won't start takes training and experience. However, we have listed some common troubleshooting that a homeowner could inspect before calling for service.
- Check thermostat: batteries, programmable settings.
- Reset breakers: as they may be interrupted.
- Check for water damage in the air handler. A blockage in the condensate drain is going to lead leaks out of the air handler into the overflow pan. it is important to keep condensation lines clean as this will prevent bacterial growth blockage. The overflow pan itself should have a separate auxillary drain line, should this line be clogged then it will overflow onto the ceilings creating some costly damage, including a possible mold problem.
- Replace dirty filters. Dirty filters can lead to lost cooling capacity first as it reduces the air flow through the system.
- Condenser fan running but not cooling. Older air conditioner compressor motor may be unable to properly compress the returning refrigerant gas to a sufficiently high pressure or it may be low on freon. Have a Penguin air conditioning service technician take an evaluation and test the system.
- Condenser will not start and is making clicking sounds. This could lead to an electrical malfunction possibly the capacitor, contactor or both. Have a Penguin air conditioning service technician take an evaluation and test the system.
- Refrigerant lines frozen ice build-up on the air conditioner air handler or evaporator coil, A common problem is reduced air flow due to a dirty air conditioning filter can cause the evaporator coil in the air handler to become blocked by ice, stopping or significantly reducing cool air output from the system. However if filters look good have a Penguin air conditioning service technician take an evaluation and test the system.
