“Gary Hays gave us great, professional service! We recently moved into a new house and when our A/C started blowing hot air, we called HMS and Gary came right out and gave a thorough investigation. He checked the attic first but wasn't satisfied he'd found the problem until he checked our pressures outside on the compressor. Apparently a serviceman from a different company had put 4 lbs of extra coolant in and overloaded our compressor. I so appreciate Gary's honesty and the knowledge he shared with us. I will not hesitate to call on him in the future and refer all of my friends to use HMS!”

“Gary at HMS was amazing and very professional. He saved the day after my wife called me while I was on the road with the bad news that our AC went out. Being away, I was worried about someone trying to take advantage of my wife, husbands can relate I'm sure. I had no reason to worry about HMS. Gary went above and beyond expectations by calling me personally and explaining the issues and choices to solve the problem. He even texted me pictures! Hard to find customer service like that anymore. My wife and I thank you, sir!”

“David with HMS was quick to respond to my water heater. He was very friendly and provided a reasonable price for new equipment and installation. I've used HMS in the past for my AC needs and will definitely use them again for any plumbing needs.”

“HMS is literally the best heating and air company you're ever going to find. We've been using them for years now and they have never let us down!!! We use them for regular maintenance and repairs. We have an older house so we've had a lot of issues and every time HMS has come through for us. They are fair with pricing and provide honest work. Everyone we've talked to has been so kind and quick to help! We usually speak to Michele when we call. I usually don't even say my name and she knows who's calling which makes the process so easy!! Gary and Andrew are usually the faces we've seen when they come out and they are so hard working and very kind people!!! These are the types of people I trust working in our home!! We always recommend them to family and friends.”
We offer 24/7 emergency service to all of our customers. You can always count on the HMS team to get to you fast and get the job done right the first time.
