Dirty AC Coil

 

During the Air Conditioning Season  we regularly get calls from home owners who are concerned about their AC freezing up  and not keeping the home comfortable during the humid periods .

Usually Coils freezing up means low air flow or a slight undercharge of refrigerant.  Low air flow is the most common.  It could be a result of a dirty filter,  dirty ductwork, damaged evaporator coil, restrictions in the ductwork or even a mismatched system where the outside unit is to large for the evaporator coil inside the furnace.

Frequently when Power Vac is cleaning ductwork  we do find blockages in the evaporator coils inside the furnace.  Blocked coils are a result of the fins of the evaporator coil getting plugged up .  The close spacing of the aluminum fins on an evaporator coil makes it easy for dirt, dust and other debris to stick. Lodged debris causes blockages, affecting the overall performance and efficiency of your air conditioning. Air flow across the coil becomes blocked, degrading heat transfer. Blockages come in the form of build-up from skin cells, fabric fibers, pet hair, grass clippings, tobacco smoke, pollen, mud, rust and bacteria.

Regular maintenance of your Furnace and Air Conditioner by a heating contractor, regular filter changes and a regular duct cleaning every 3 years with help to ensure that your heating and cooling system runs efficiently  and keeps everyone comfortable when you need it most.
