We had an urgent need on Christmas Eve as our furnace completely stopped running, no warning, no prior issues. Our regular HVAC company had once said they didn't work on a Nest and my husband had heard TE Certified advertise on the radio and suggested we reach out. Koi Perng was the technician assigned to our situation and he did a thorough inspection of our unit. Unfortunately, he didn't have good news and our furnace required a lot of work. It seems the company we had been using for the last 2 years had never made us aware of all the issues with our furnace. Because of the holiday and needed parts, it was 4 days before Koi could come back and fix our system. He was excellent, took videos of his work and walked us through every step of the process, what our unit looked like before and after, and patiently explained how we likely got where we were and why such extensive work was necessary. While I wouldn't wish our situation on anyone else, Koi, and others at TE Certified made it a positive experience. We will continue to use TE Certified for our annual maintenance and highly recommend their service.
