An air conditioner is a sophisticated piece of machinery, and AC repairs of your unit should be trusted only to a professional. Unless you have above average AC repair skills, it's not recommended that you attempt any air conditioner troubleshooting on your own. One of the biggest causes of air conditioner problems is improper maintenance. Keeping your unit clean and free of debris is something every home owner can do. Simply remove the protective cover, and clean dust and dirt off the condenser fins. Hose down the fins if necessary, taking care to avoid splashing water on the motor and wiring. Accumulation of dust on the fins can reduce the cooling efficiency of your unit. Major AC repair problems like compressor failure, can also develop.
Improper installation of your air conditioner is also a leading cause of air conditioner problems. For instance, if your AC technician did not charge the correct amount of refrigerant during installation, the unit can quickly develop leaks. Improper operating procedures can also lead to air conditioner repair problems. For instance, switching air conditioners on and off frequently can cause the compressor and fan controls to wear out. if your air conditioner does not switch on immediately, check to see if the thermostat has been set to "cool". It should also be set to below the room temperature. Check if the breaker has tripped or if a fuse has blown. If you notice grinding noises in your blower, call your AC repair technician. Usually, it's a problem with improper belt alignment. If you notice pools of water accumulating next to the unit, check to see if there is a leak in one of the tubes. If not, it could be a problem with the pump.
AC repairs tend to be complex procedures, and because your air conditioner is an expensive piece of equipment, it's best not to get experimental with repairs. A central air conditioning troubleshooting technician will be able to conduct all kinds of repairs related to your unit, including AC compressor repairs, AC duct and motor repairs and other central air conditioner repair sources.
