This house did not originally have a roof–mount cooling and heating unit. We converted the air conditioning/heating system from a Lennox split system, with the air handler located in the foyer closet to an American Standard package unit located, as seen in this picture, on the roof. The customer wanted a more spacious vestibule, and this he obtained. We removed the air handler from the inside and installed this 12 seer American Standard package heat pump outside, as requested by the customer. We redid all of the ductwork and added on duct for his Arizona room. This system was installed in Pheonix, AZ.
