Triangle Ratings & Reviews

Triangle Heating & Air Conditioning BBB Business Review

Triangle Testimonial:

"I just wanted to reach out and express my appreciation for a job well done. From when you first stopped by to discuss our HVAC needs until Charlie Good showed us the ropes on the system, it was professional and it was thorough. Joe, you were prompt with getting a proposal to us and followed up on regular intervals, but you were not bothersome. We had gotten a bid from another company and we needed to repeatedly call for the bid, and after we received the bid we never heard from the sales rep again. Thank you for an excellent job.

Please pass on to Charlie Good our appreciation for being diligent in getting the system installed and running. We were impressed with his efforts to keep any dust from the installation to a minimum. He also was professional in any interaction we had during the installation process.

Again thank you... we are very pleased.
