Air Conditioning Maintenance and ServicingAn air conditioning system is a complex mix of machinery and electronics. Careful maintenance keeps an air conditioner running effectively.Before attempting any central air maintenance, read the owner's manual carefully, and only perform maintenance tasks the manual recommends. Leave all other tasks to an air conditioning service.Air Conditioning BasicsAir conditioning maintenance starts in the early spring. Check the outside condenser to make sure it isn't covered with debris, leaves or other items that could impair air flow, then turn the system on for a few minutes to make sure it still runs.Don't wait until the heat of summer to check the system: You'll get faster service from an air conditioning repair company in the spring than during the height of summer.Other simple, early spring air conditioning maintenance tasks include:Making sure all access panels are secureSetting the thermostat to cooling modeTrimming bushes and trees close to the condenser.Changing Air Conditioning FiltersChange air conditioning filters every month when the system is active. Disposable fiberglass filters can simply be replaced once a month. Electronic or electrostatic filters can be taken out and washed according to manufacturer's instructions.Air Conditioning Maintenance and MoldCheck condensate drain pans for mold and other potentially harmful growths. Mold can be cleaned off pans with a mixture of one part bleach to ten parts water. Be sure to rinse pans well with fresh water after cleaning them with the bleach solution.Annual Air Conditioning ServiceAir conditioning service companies are busiest during the summer, and may not be able to accommodate you if you wait too long. Homeowners should schedule an air conditioning service every spring, before the heat of summer.An air conditioning service takes care of central air maintenance tasks that are too specialized to be safely handled by homeowners. During your annual air conditioning service the service person will complete the following tasks:Calibrating the thermostatChecking all electronic partsChecking filters and condensersChecking Freon® levelsCleaning the evaporator and condenser coil, if necessaryCleaning the air conditioning drainOiling the motor, if necessary.Some online resources suggest cleaning external air conditioner components with water and a garden hose. This practice can result in electric shocks and damage to the air conditioning unit. Cleaning the interior of a unit is best left to an air conditioning service.Need More Help?If you need professional help with your project, LendingTree Home Pros can help.The good news is that LendingTree Home Pros maintains a directory of home service professionals and can match you with a home pro in your area.
