Our furnace stopped working, and our house was really getting cold. The first repairman we tried was unable to fix our furnace, and we were still cold. Luckily, I talked with my friend and she recommended Triangle. In one short visit (and for less than half of what we had paid for our other unsuccessful repair work) our furnace was up and running! Ben, our technician, assured us that he did know what the problem was, and he was able to warm up our house quickly! He explained that our former repairman had tried to use a part that wasn't compatible with our brand of furnace. Ben had the right part on his truck, he installed it efficiently, and we had heat again! We heartily recommend Triangle, a company that believes in fixing/repairing rather than just selling a new unit. Our serviceman was quick, professional, and friendly. What a great combination!

  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.

  Josh came so quickly they squeezed us in and were rapid with not only response but service! He was extremely professional and knew exactly what had gone wrong and had us up and running again within no time at all! Highly recommend we will utilize them for all of our future service needs!

  I requested a service call that included a tune up. Ben was fantastic. He was knowledge, professional, and quick. The company as a whole was very accommodating to a last minute rescheduling that I had last week, too. The price was fair and I plan on making this service a routine with them. If you're searching for a company to trust then you just found it.

  Did a great job ,very polite and informative and on time .

  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.

  Quality service from people you can trust. They have come to our rescue many times throughout the years. We've been using their services since 2003 and have never had a bad experience. Good honest people.

  the tech was here on time, knew what he was doing and had the required replacement parts in the truck. once again, prompt and efficient service from the triangle, highly recommended.

  Josh was great in every way. Very friendly and was very thorough. Fast response to my call and my furnace was fixed within a day. So glad with the cold weather it might not have lasted and we would have been without heat. The girl that scheduled us was also very nice and had Josh come out the day I called to address what type of problem our furnace was having. I have used them in the past for my air conditioning problem which was also fixed very promptly and the service was great then. I will continue to use them for any service needed in the future. I would highly recommend them to anyone who needs these types of services. Thanks to everyone at Triangle for taken the worries away when you need fast efficient affordable friendly service.

  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!

  OUTSTANDING service; from the initial response to completing the job. Both the office staff and especially Josh, the repairman, our satisfaction was their major concern. Great to deal with a small, local company. They will get our annual checkup business.

  Triangle AC helped us do a major HVAC installation for our property of about 6 units. Job was completed on time and with quality work. Would highly recommend!

  Thank you Kevin for explaining my heating problem and for the fast and excellent service. I have used Triangle Heating and A/C in the past and they always came through for me . And because of employees like Kevin I will continue to use Triangle in the future for all my heating and A/C needs . I will also refer Triangle to anyone I know who need service or a new A/C or heating unit .

  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.

  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.
