DIY: Fix My AC Problem

Before calling a qualified air conditioner repairman, there are a few simple steps you can take to troubleshoot your air conditioner problem.

If the air conditioner does not turn on, check the power. If it is a room air conditioner, make sure that the plug is firmly plugged in. Also, check the fuse or circuit breaker to ensure that power is reaching the unit. For a central air conditioner unit, you may want to try the reset button in the compressor’s control panel. You should wait 5-10 minutes after the unit has stopped before resetting the compressor or resetting a circuit breaker.

If the unit is running but just not cooling the room appropriately, make sure that all windows and doors are closed and that the cold air is not leaking out of the room. Other items to check are the filters and coils. If these are not maintained properly, that can impact on performance. When the weather is unusually humid, the unit may not be draining properly so you should check and make sure that the drain is not clogged.

When your central air conditioning system is not working properly there are a few things you can check before calling the repairman. Make sure that the outside condenser is not blocked; is the grass too high, are there weeds or debris blocking it? The evaporator may be dirty and in need of cleaning so you can check your operator manual on the steps to clean your unit.

When your unit is running but not cooling the room to the desired temperature you may want to lower the thermostat by five degrees to see if it is a thermostat problem and not the air conditioner unit itself.

One thing to remember is to give the air conditioner unit time to cool the home. If the air conditioner has just been turned on give it some time to work. If it has been unusually hot (or humid) the air conditioner simply may take longer than usual to cool the room.

Once you have tried the above suggestions, it may be time to consider calling a qualified repairman to resolve your AC problem.
