"Haller removed an old ac system and replaced it with a heat pump. The work included installing an additional return in the family room (split level home) to return air from the lowest point in the house. The crew was knowledgable, their work was neat, and they cleaned up at the end of the day. The work was completed in 2 days and the new Carrier system works great so far. Looking forward to see how it performs next fall and winter."
