When I first moved into my home a friend recommended Knight Air. They were a family owned business, honest, reliable and reasonably priced. I’ve used a few different companies since they sold their business. I think I finally found my new company with TE Certified. I received a text from Jonah with his picture, introducing himself as my tech and telling me when to expect him. He actually showed up early. He was polite and professional and respectful of my home. We talked about the problem and the age of my units, then he went to work. He informed me of his diagnosis and I authorized the work. He later presented me with a written report of the work he’d done and recommendations for options I might want to consider. He was the consummate salesman - personable without being pushy. I declined his recommendations but I did sign up for their maintenance plan. He informed me that the previous tech had installed filters that were too small so he replaced them with the proper sized filters. I learned they also have certified electricians and plumbers. From my experience with Jonah I highly recommend TE Certified for your HVAC needs.
