Our roots are in the commercial field, helping businesses all over Maryland stay comfortable. Check out this success story (on the left!) from Hughesville Fire Department.

Customer Testimonials

  • Happy to report EXCELLENT results from Pro-Tech HVAC Home led by co-owner Chris Mahoney & his outstanding team. After obtaining 3 estimates to replace HVAC (heat & A/C system) Pro-Tech was the clear choice. They gave us the most value for monies spent. Chris is a hands-on co-owner & couldn’t have been better from a customer satisfaction standpoint. Include me on his long list of “Happy Campers” when it comes to a job well done. Chris refused final payment until he was assured of our complete satisfaction with the installation. Very refreshing to find a company that delivers on all promises & leaves us with a feeling of complete satisfaction. Kudos to Chris, Rocco & the entire team of Pro-Tech professionals.

  • I want to highly recommend Pro-Tech HVAC Home…a true team of professionals. My wife and I got a Mitsubishi system installed and a drastic difference was felt immediately! The installers were clean, courteous and dedicated to their profession. Rocco was very personable with making sure we knew what we were getting and how to operate everything.

    Paul Markham
    Happy Mitsubishi Customer
  • Chris and Pro-Tech HVAC Home did a great job replacing a gas furnace and an HVAC unit at our property. They were professional, timely, detail-oriented and provided a good product for a fair price. I would hire them again and am comfortable recommending them to a friend.
