Suburban Homes Reaching Their Next Replacement
Located Just West of You
Serving Allen for 10+ Years
Allen is a large Collin County suburb built mostly from the late 1980s through the 2000s, with neighborhoods of brick homes along US 75. Many of those houses are on their second system now, and plenty of homes still have their water heater in the attic, where an aging tank can cause real damage when it finally leaks.
There is no shortage of HVAC companies in Allen. What we offer is a small shop where the person who diagnoses the problem explains it to you directly, and no one is paid to sell you something you do not need. We make the drive from Krugerville, about thirty five minutes away. HMS Heating & Air Conditioning has been in business since 2015.

What Locals Say
Service People Recommend
Google reviews copied exactly as our customers left them. The same two things come up: a fast visit and an honest explanation.
HMS work was excellent. They took the time to determine where my house's problems were and fixed them. So much so that before their work my house was listed by my energy company as much worse than the average but now ranks…
I had the best experience with HMS. Their techs were respectful, professional, knowledgeable, and kind. I will only work with HMS moving forward.
Gary and Nate did an awesome job fixing our outdoor unit. They are professional and honest. They are the company we trust.
Nate was great. Inspected our 1 year old HVAC system, cleaned the external unit. They have a very affordable maintenance plan that include twice annual checks and cleaning. Thanks, 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…

Frequently Asked
Questions
What Allen homeowners ask us about attic equipment, replacements, and choosing a smaller company.
Still not sure, call our team (940) 222-9313Why would a Krugerville company come to Allen?
Because customers ask us to. It is about thirty five minutes away, and many Allen homeowners prefer a small company where the owner stands behind the work.
Our water heater is in the attic and over ten years old. What should we do?
Plan a replacement before it fails. When we replace it, we make sure it sits in a pan with a working drain line, so a future leak goes outside instead of through your ceiling.
Is it time to replace our second AC system?
If it is around fifteen years old, needs frequent repairs, or your bills keep climbing, it may be. We will test it and give you an honest assessment, not a sales pitch.
Do you check for carbon monoxide during furnace service?
Yes. We inspect the heat exchanger and test combustion on gas furnaces. Every home with gas appliances should also have working CO detectors.
Is duct sealing worth it?
In many homes from the 1990s and 2000s, duct leaks waste a noticeable share of the air you pay to cool. Sealing the worst leaks can improve comfort and lower bills.
Do you offer financing to Allen customers?
Yes. Our financing partner offers a quick online application, and approved projects are scheduled right away. Start on the financing page.
There is a water stain spreading on my ceiling. What should I do?
If it is below the attic equipment, turn off the AC and shut the cold water supply to the water heater if it is up there too. Then call (940) 222-9313 so we can find the source quickly.
