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.

    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.

  • 10 out of 10 satisfied customer here! I can’t say enough good things to express how happy I am with Pro-Tech HVAC Home’s service. From when I first called and was able to talk to someone who was knowledgeable & listened to me describe my AC problem, to when he came out and efficiently worked on and fixed it, I felt so lucky that I had found them. Around a week prior, another AC company had came out, but didn’t help and didn’t give me any options other than trying to pass it to an electrician (I found out the expensive way that this wasn’t right). Pro-Tech was able to find and resolve the problem in a little over an hour. They worked hard and efficiently, the price was extremely fair & to top it off, very personable and professional. Pro-Tech has saved my summer!
