August 15, 2020 I have worked with Triangle on a ton of repairs to my rental properties and personal residence over the years and have had nothing but the best possible experience.
Most recently my boiler at my personal home was out and they were able to install a new one promptly and even offered to provide me with space heaters to keep my family warm while I waited for the new unit to arrive (which did not take long at all)
The work was performed quickly and professionally and the system works great!
Thank you so much! Will continue to be a lifelong customer. Anthony Angotti
February 10, 2021 Triangle was very easy to work with on an AC install , made sure I understood everything that was going into my house, and provided excellent on-site support a year later without even charging us because we didn't know that we had to change an air filter. Very happy with my experience with them.

August 11, 2021 Woke up one morning my furnace wasn't working. I called Triangle, and within 15 min. the repairman was here. He knew exactly what was wrong and had the part on his truck. The repairman was very professional. I would highly recommend Triangle.

June 28, 2019 - I contacted Triangle on a Monday during a 90+ degree week! Ben was able to schedule an appointment the same day! Josh, the technician, arrived within 2 hours and had me up and running within 20 minutes! I cannot say enough good things about this company! Pricing is fair, responsiveness is 2nd to none, and they're not only quite knowledgeable, but, most importantly, they are honest as well.
Thank You, Triangle, you have a customer for life!

July 18, 2020 Extremely trustworthy company who helped me find the small costing issue with my furnace instead of trying to sell me a new unit like the other two companies I reached out to. When I’m ready for a new one I will be using triangle. Thank you for being honest professional and very helpful. Don’t hesitate to call them! Kevin Coppler

March 23, 2021 I received a call back from Justin at Triangle today and he was very
courteous and informative. He set up an appointment to give me
a free estimate on replacing my oil boiler with a high efficiency gas boiler
including a heat analysis of my home. I am look forward to the appointment next Weds. Shari C.

November 17, 2018 - Our furnace stopped working this morning. We noticed around 10 AM and made a call to Triangle. Within an hour I got a call back and a technician was at my house within 10 minutes. Our issue was diagnosed and the technician was able to find a replacement part within driving distance. Considering it is the Friday before a holiday weekend I expected we wouldn't have heat until next week, we are warm and toasty with everything working in less than 4 hours from first even noticing the problem. Our neighbor recommended Triangle to us and I will recommend them to everybody who asks!
