After a few months of Winter, our AC systems need a little TLC to get them back to their best performance. We recommend getting a professional tune-up and maintenance visit from Evergreen Heating and Cooling. Things that need to be checked: Filter; Refrigerant Levels; Motor Amp Draw; Compressor Amp Draw, Drains, and so much more. Correct maintenance visits should increase the life-span of your HVAC system and prevent nuisance service calls in the summer.
