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.

Worth getting a estimate

Kind of disappointed in the leak detection. I know it was a small leak and hard to find but, I had to pay y’all then get another company to find it . Your employee was great, but having to pay twice was not great.

Can't beat the service

After discovering our plumbing problem was a little more involved, Mr Mays had to come out to replace some of the drain from our laundry room. The plumbing is in our crawl space (unfortunately) but Mr Mays did the install as if it were inside the kitchen. He took pictures and sent me the work...which was perfect. Can't beat TE Certified and it truly is because of people like Mr Mays. Thank you!

Very professional. Excellent service!!

Ben Pollard was my tech. He also had another gentleman with him and for the life of me, I can't remember his name. Both of these guys were very professional and hard working! They explained the problem well and repaired it very quickly. I would definitely use TE again!

Excellent Service

Mr. Diaz did a thorough analysis of my HVAC system and gave options for repair/replacement. We discussed the age of my system, did a cost/benefit analysis and came to a solution. I appreciated his input.

Perform a systems home care maintenance. Change filter, tested all electrical components, flushed drain line, tested thermostat, Tested both system on cool and heat, checked pressures and refrigerant. System is working properly at this time, however notice biological growth is spreading around duct work, highly recommend to add a germicidal device to the unit to stop the spreading and purify the air.

Te certified will use a sewer jet to temporarily identify the remaining run of the pipe to possibly offer a rerouting option

For this job I came to see why customer was not getting hot water. I found that the connections on the water heater were faulty and not getting electrical current to the water heater. I re stripped the wires and added new wire nuts to make connections. After that was done I was getting proper electrical current to the unit and it fired up. Tested and left work area clean.

Replaced all of flue pipe, tested system and everything ran great. System ran without any error codes. Temperature went up on thermostat. Opened doors to room upstairs to help circulate air flow better and that helped a lot for system. Will return to install the flue temperature sensor when it comes in.

Run 400 cable and clear blockage, set toilet on new wax ring Camera inspection follow up Customer was having mainline blockage affecting toilet,sink,washer, and kitchen sink. The other fixtures were draining fine because they were tied on a different stack. Ran k400 in drain and were able to clear blockage. When testing washer machine a little amount of water would push back but then drain immediately, possible slope issue. We left toilet off for camera tech.
