Heating And Air Conditioning Repair (How to Do It)

An air conditioner’s condenser and evaporator are separate components. The condenser unit is usually located on a concrete slab outside the house. Above the furnace is the plenum or main duct junction where the evaporator coil is located.

Forced-air distribution systems are usually connected to central air conditioners. A similar motor, blower, and ductwork are used to distribute cool air from an air conditioning system for heating. A return-air duct transports hot air inside the house to the furnace when the central air conditioner is operating. Blowers move hot air across the evaporator coils in the plenum and then deliver it through ducts to cool the house heating and air conditioning repair The distribution system is probably malfunctioning when the air conditioner works, but the house does not cool.

You can’t make any repairs yourself, but there are specific maintenance procedures you can follow to keep your system running smoothly. There is a seal between the evaporator and the condenser. The only exception is routine cleaning, in which a professional service person should be contacted. A professional inspection and adjustment of central air conditioners are recommended before each cooling season. Don’t let this annual examination by the end of your maintenance.

To get the most out of your air conditioning system, you need to understand how it works. With some basic troubleshooting techniques, you can keep it running efficiently for years to come.

Cleaning the Evaporator

Evaporators for central air systems are located directly above furnaces in plenums. It may not be possible to clean the evaporator every year, but if you can, you should do so. Evaporators with foil-wrapped insulation can be cleaned; those with sealed sheet metal boxes should not be opened. The following steps will guide you through cleaning and accessible evaporator:

  • You probably have foil-wrapped insulation taped to the front of the plenum, so you need to remove it first. Remove the tape carefully since you will have to replace it later. The insulation is held in place by several screws that are held in place by the access plate. Lift off the plate by removing the screws.
  • The entire underside of the evaporator unit should be cleaned with a stiff brush. Using a large hand mirror can help you see what you’re doing. Sliding the evaporator out will allow you to reach the entire area. It is possible to slide the evaporator out even if it is connected to rigid pipes, but take care not to bend them.
  • Cleaning the tray under the evaporator unit is the third step. The tray carries condensation away from the evaporator. To prevent fungi growth, pour one tablespoon of household bleach into the weep hole in the tray. The wire should be used to open the weep hole. The condensate pan and drain should be checked every two days during extremely humid weather. Whenever there is a lot of moisture in the pan, the weep hole from the pan to the drain line may become clogged.
  • They are replacing the unit, reinstalling the plate, and retaping the insulation complete Step 4.
  • The fifth step is to turn on the air conditioner again and check for leaks in the system. Duct tape should be used to seal any leaks.
