All air conditioners require occasional maintenance and some problems are simple to fix if you know what you are doing. If the air conditioning system is running but the air coming from it is not cool, you may be able to solve the problem with some simple cleaning.
Study the user’s manual or look for a copy online if you have lost the one that came with your unit. It will be easier to detect the problem if you examine the unit on a warm day.
Never attempt to work on an air conditioning system before you turn off the power to the unit. Look for the unit’s shut-off panel and make sure the power is off.
The first thing you must to do to find the problem is remove the condenser cover. Use a soft cloth or brush to clear away any dirt and debris while being careful not to damage the fins. After cleaning them off, you should dry them.
Unscrew the grill cover and remove It carefully making sure you do not loosen any of the wires attached to it. Cover the motor with something that is waterproof and use a hose to clean the fins. While the unit is dismantled is a good time to lubricate the motor. Replace all the parts you removed and your repair work is complete.
After the unit is put back together, turn the power on and allow the system to run for a short time. Touch the pipes that are attached to the condenser. One pipe should be warm and the other pipe should be cool if the unit is working properly.
If this is not the case, the system may need a refrigerant charge. This is not something that you can do by yourself. You must call a professional air conditioner technician for assistance.
If the air conditioner fails to turn on at the proper time, you will have to check some additional parts. Set the thermostat at a temperature that is cooler than the room.
The problem may be a tripped breaker on your main circuit panel or a fuse that has burned out. Make sure the condenser switch on the outside unit and the power switch are both in the on position. Look next to the compressor and make sure the 240-volt disconnect is turned on.
