See What Our Happy Clients Say

What a great experience! I called Hays and the office staff was so accommodating and friendly. They communicated clearly professionally. The technician called me about 30 min before arriving, quickly diagnosed the issue and have me a clear understanding of the issue. My unit was back up and running within 30 minutes.

On the recommendation of a friend, I called Hay’s for my spring a/c maintenance. The service was great. The technician was pleasant and helpful. For once, I didn’t feel like a heating and air company was trying to take advantage of me. Pricing was very reasonable. I will definitely use them

Sarah M.

Several of my HVAC units were struggling to cool given the 95+ degree temperatures. I called Hay’s and they sent Brad out to see what was going on. Hay’s installed the HVAC units 15 years ago. Brad wore a mask. He cleaned all of our units and added refrigerant. Brad worked swiftly and efficiently.

Brad was AMAZING!!! When our air conditioner stopped working last night, we were worried that it would be days before someone would be out to look at it. We woke up and the house was 10 degrees warmer than when we went to bed. We were told that someone would be out at noon…

The Hay’s Heating & Air Conditioning company has always been Johney on the spot as to getting someone out quickly as needed, made the repair or ordered the part. The serviceman also kept me informed of what repairs were made and service was done on their visit.
