What Our Clients Have to Say

    • Precision Air & Heating is truly a reputable company and certainly number one for service in my book. Shawn, the repair manager was extremely helpful and professional. I would recommend them for both installation of a new system as well as repairs on your existing AC.

    • We were visiting our Arizona home from New York, when on one of the hottest days in August the air conditioning was not working. We called Precision & James Shelton worked to get the air up & running in no time. He was courteous & sympathetic, working hard to repair our central air…we have a warranty & Precision stands behind their work, they are available 24/7… Thank you!

    • Service was completed in a timely manner and my technician was extremely knowledgeable. All services were explained to me prior to being completed as far as the need and cost are concerned. My air conditioning unit has been problem-free all year and I believe it’s because of the professional maintenance that I get yearly from Precision Air.
