Very good Technician providing Excellent Service!



Not one who does a lot of reviews, I’m extremely impressed with the HVAC Technician Jason Braunstein, and the company that he works for, TE CERTIFIED! A review is warranted. I’ve been a long time customer of one of TE Certified competitors for years, but after today, that loyalty may have come to an end. Needing my winter checkup on my Lennox gas furnace but not yet hearing from so mentioned competitor, as I normally do. I decided to call them and see if they could come out for a service call, the date is 12/23/25 but they didn’t have an available appointment for service until 01/15/26! That was unacceptable! I had many HVAC companies to choose from but remembering a jingle from the radio “TE CERTIFIED WE LOVE YOUR HOME” and checking the company’s reviews, all very good. I decided on them and made the call, and I’m sure glad that I did! The receptionist was very courteous and very helpful, and scheduled me an appointment that very same day! The Technician, Jason Braunstein arrived as scheduled and provided excellent service. He was very nice, polite, and very knowledgeable of my Lennox gas furnace. He inspected the furnace thoroughly! He adjusted the heating system to give our home the proper warm air temperature that matched the thermostat reading. He gave me a complete breakdown and inspection evaluation of my system, along with pictures, sent to my email very soon after he left. I was very impressed with TE CERTIFIED and must say that based upon the expertise of their employees and how “They Loved My Home” :-) I will be calling them again! And, I hope to have Jason back as my homes personal technician. Thank you Jason, and thank you TE CERTIFIED for providing what you say you will do on your radio adds, love our homes! A very satisfied customer, Zack S.
