Arrived on site for home hvac inspection. Checked in with customer and checked both thermostats for power and functionality. Per customer “ I had a landscaping company out here and they completely covered the condenser outside with mud, I use my water hose to try to clean it off, but I know I didn’t get it good enough. I have a family member who lives with me who has lupus, it needs to stay cold inside of the house, so it is detrimental that everything is OK.” Started with the furnace in the attic, checked all electrical connections for tightness, system was already running in cool mode, started up in heat mode to ensure everything was working properly. Filter is changed every two weeks by customer. Insured blue tube is working properly. Went outside to condenser, the condenser is louder than normal. Checked capacitor, contactor, refrigeration levels, and coil around unit. Found coil to be extremely dirty still. Recommending a coil cleaning.

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.

Javier was assigned with Nathan to my project. I'm absolutely happy to have contracted to TE Certified for my project because of good working professional like Javier. His job is top quality and he constantly communicates with me whenever there are some potential challenges he see with my original plan. Javier also go all the way out in his work, including crawling near the edges of the attic/roof during the installation of the PoE cable and WiFi AP. I greatly appreciate all the nice work Javier had done for my project. Highly recommended!
