I called A and C Mechanical after returning from vacation and finding out my central air unit was involved in an electrical strike. Arthur showed up when scheduled. He fixed the central air pretty quickly and very reasonably priced. I had him come back and service my furnace for the fall/winter and he found a bracket that needed to be replaced. Again very happy with the service and pricing.

Thank you A and C Mechanical for providing PHENOMENAL Service!!! Last winter during the Christmas week (Saturday to be exact) on one of the coldest days of the year our furnace stopped working - No Heat for the entire house!
A and C came to our rescue! First off, they answered my call on a Saturday, came out to the house, fixed the furnace, and did NOT charge an astronomical fee !!!!!!! They were friendly, professional and very willing to help us in our time of need. They also gave us some maintenance tips that would prevent this situation from arising again. It was a Fabulous Pre-Holiday Gift!!!
THANK YOU A and C!!!!!

First used A&C a year ago. My furnace failed in January, they came right out and replaced the furnace the next day. The work was done fast, professionally, and well priced compared to other quotes. I have since had them back to looking into upgrading duct work and will be having them do that as well.
