Aire Serv Tucson, Tucson

Backed by a litany of guarantees, Aire Serv's climate techs install, repair, and tune up air-conditioning and heating systems. They replace broken units or units throwing temperature tantrums with Trane- and Carrier-brand equipment and execute mechanical and electrical maintenance on all varieties of brands. Keeping air conditioners and furnaces running smoothly increases energy efficiency and can lower utility bills. The crew further improves that efficiency, along with air quality, through duct-cleaning services. By installing clean filters or adding electronic air cleaners to the home, they greatly diminish the amount of dust, mold, and allergens swimming through the home's air. In step with green technology, techs also install geothermal heating and cooling systems as well as solar and wind systems.
