Remove a Wall-Mounted Air Conditioning Unit and Clean an Air Conditioner Exchange Unit
Single room air conditioners provide you with comfort especially during hot summer days. Room air conditioners come in many forms and sizes, but the wall-mounted type is one of the most common types of air conditioning units seen in residential areas. Air conditioners have a limited utility life, meaning sooner or later it will be necessary to remove your wall-mounted air conditioning unit.
How to Remove a Wall-Mounted Air Conditioning Unit
Removing a wall-mounted air conditioning unit is not a difficult task, but is one that definitely requires an assistant. Unplug the air conditioner from its power source. Carefully pull the plastic front cover of the unit on each side let and right one at a time to remove the cover.
Remove any attached drain hose that is connected to the unit. Have an assistant hold the case, and slowly pull the unit forward until it is fully withdrawn from its case. Lay the unit on a lat surface.
View the inside of the units casing. Locate any screws used to fasten the casing to the studs or plates around the units casing, and remove such screws, using a screwdriver. Pry away any portion of the casing that has gotten stuck to studs or plates around the casing, using a wonder bar.
Pull the casing slowly out of the wall opening to remove it. Take extra care when handling the casing to avoid cuts that can be caused by sharp metal edges. Place the casing carefully on a flat surface.
How to Clean an Air Conditioner Exchange Unit
Routine maintenance cleaning can prevent the air conditioners exchange units from filling with debris. Disconnect the electricity supply to both the inside and outside air conditioning units at the circuit breaker box. The correct circuit breakers will have labels that read Air conditioner for the outside unit and either Furnace or Air handler for the inside unit.
Unscrew the air handlers panels with a nut driver. Most air conditioning equipment uses screws with either 1/4 or 5/16 inch heads. Keep the screws in a safe place.
Pull the panels off of the air handler. This will expose the inside heat exchange unit. The exchanger has thin aluminum fins covering copper tubes.
A drip pan, located below the exchanger, collects condensation for the drain line. Spray the exchangers fins with an aerosol coil cleaner. This non-rinsing spray cleaner will foam on contact.
The foam will lift the debris from the exchanger and flow down to the drain pan where it will enter the drain line. Move to the outside exchanger while the foam works. Cut any grass that has grown into the outside exchangers fins with scissors.
Pull the grass out from the fins and the wire cage that surrounds the exchanger. The outside exchanger, also known as the condensing coil, should have the grass removed from it after mowing the lawn.
Air conditioning systems use refrigerant to transfer heat from the inside exchange unit, the evaporator coil, to the outside exchange unit, the condensing coil. Maintaining the air exchange units will increase the life of the air conditioning system and lower the cost of running the equipment. When an exchange units fins have extreme amounts of debris between them, potentially fatal damage can occur to other parts of the air conditioning system.
