  • Fantastic job! We had another company come out before Triangle because our AC wouldn't kick on and they told us we needed a brand new unit for $4850. Then comes along the wonderful Kevin from Triangle. He got our unit up and running (after fixing some wiring the other company left dangling) and told us there was nothing wrong with it. I was referred to Triangle because they're an HONEST company and now I believe it. Thank you, Kevin!

    Hired Triangle to replace my tired furnace before the weather turned cold. Notes below: + Pricing was right in the middle of the quotes. Completely fair — not the least costly, but no where near the highest estimate. + Selected a Lennox furnace — I think this is Triangle’s preferred brand. + Scheduled the job in only five business days after we selected Triangle. 👍 + Two-man crew showed up right on time (8:30A) and the job was complete at 2:45P. + Installation is clean and tidy. Triangle worked clean and left the area spotless — cleaner than when they started. + Unit works great. No issues at all. Highly recommend, no qualifications or reservations. Great work, on time, and at a fair price.

    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!

  • On July 4th, we lost power. When the power was restored, our furnace fan was damaged due to the violent power surge so we had no air conditioning in the brutal heat. I called Triangle and Josh responded almost immediately after I talked to the answering service. He came out the next morning, had the part ordered and installed the next day. Very professional and courteous at all times. Special thanks to Josh and the office staff at Triangle for a great job! Thank you!

  • 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.

  • My furnace dead in the dead of winter. Huge issue. Triangle came through for me in a day. I thought that was impossible. And at a great price compared to other quotes.

    So, it's three days before the big holiday and my furnace quit working. I thought I'd have to wait for days, especially with all the COVID staff shortages to get someone to look at my furnace. I was originally told they could be here next day, which was great. They ended up calling me back a few moments later and said they could actually have someone here in 30 minutes! Ben (I think?) showed up promptly, was very personable, and explained to me what was happening with the furnace. The price was fair and I couldn't be happier with my experience with Triangle Air Conditioning. I will definitely be a repeat customer and highly recommend this business. Thank you!!

    They were excellent. They were able to come check on my air conditioning an hour after I called and were able to diagnose and fix the problem very quickly. They were quick, efficient, and professional. I was very impressed with their service.
