Equipment manufacturers, utility companies & CHAC encourage preventative maintenance of central air conditioning and heating equipment. Peak efficiency, maximum system capacity, extended equipment life; lower energy costs and better indoor air quality are the major items of importance and consideration.
Your air conditioning and heating system(s) was a major investment on your part and a little care can save you money as well as unnecessary and costly breakdowns and repairs. In some circumstances the equipment operates in both the heating and cooling modes so it makes sense to have it cleaned as early in the spring and fall as possible. All types of HVAC comfort systems should be regularly checked and cleaned with no exceptions!
