Your heating, ventilating and air conditioning system can lose its efficiency every year if it misses a tuneup. Conventional central heating and air systems should be serviced twice a year: once in spring for cooling season and once in fall for heating season. An air conditioner system’s performance can decrease from buildup of dirt, wear of components and improper refrigerant levels. Your system tuneup will help prevent costly repairs, extend the life of your system, and save energy and money.
