Keeping the coils clean on the exterior unit is the most important maintenance your air conditioner needs. Clogged coils can cause up to 25% waste in energy and makes the AC unit work much harder to cool your home. Manufacturers recommend cleaning the coils at least once a year. If there are cottonwood trees nearby, you should clean them more frequently, especially when there is a lot of cottonwood in the air. Keeping the coils clean may also prevent manufacturers from denying a warranty claim due to lack of air conditioning maintenance.
Cleaning the coils, fan and housing can be done by the homeowner with a garden hose, but care is needed to make sure electrical power is disconnected properly and disassembly and reassembly of the housing and fan is done correctly.
Inside the home, there is a drain hose or pipe that removes 10 to 12 gallons of condensation water per day from the system. Often it will empty into the floor drain. The line needs to be kept clean so that water does not back up into your furnace unit. Ditter performs regular cleaning and maintenance of the entire AC unit for members of our Maintenance Program, or you can simply call us at 763-200-5055 or request an appointment.
