Aire Serv did a stellar job on the install of a new air conditioner (heat pump? I don't remember, the tech said which, my minds just not all there) ducting, and an air handler (if i recall correctly) the tech was very professional, extremely courteous, walked me and my brother in law through every step he took and the reasoning behind it. He was very knowledgeable about how best to fix the issue. Since then the things been working great and any time there's a question or issue i can call them up and get a prompt answer (like forgetting to change from heat to cool on a warm day!) Overall i would (and have) recommend this company to family and friends whenever they have problems.
