Cleaning evaporator coils -and why you should do it!
Even a system that has been well taken care of with regular filter changes will have dust and dirt build up after many years of use. A coil plugged with dust and dirt will restrict air flow, causing all other system parts and motors to work harder and putting strain on the system. A clogged coil can limit function, or even cause the system to ice up and totally malfunction. Get more cooling years out of an older system by having the inside coil cleaned and get that system breathing again.
