Air McCall gave a prompt competive bid on a total A/C replacement and duct replacement. The bid was very detailed for all the work they were doing. The 3 man crew arrived when they said and were very professional, polite and courteous. The guys had a good game plan for the 2 day job and I was not without cool air, execpt for when they physically changed units. They layed tarps throughout the house were they worked. When they left each day you never know they were here. They answered all my questions, walked me through all they did, and explained how to operate the system before they left. Outstanding job!
