"Robbie and team showed up and replaced two completely dead HVAC systems with highly efficient Rheem inverter systems. In the first month alone, my electric bill has dropped from ~$550 to $250 - now that we're not relying on heat strip heating. They were excellent, describing everything that they did and walking us through using the new systems. No surprises on the bill, either - just straight forward and honest. I'd highly recommend them in the future, without reservation."

"TE Certified is my go to company for any services they provide. I had 4 heat pumps replaced with them, various plumbing/electrical, and most recently a whole house generator. Billy did a great job showing the generator options and managing the sales/install cycle. Matt and team did a fantastic job installing the system and showing me how it all worked. TE Certified always uses high quality materials and workmanship for long term error free operations. The county inspector even commented on how good it all looked. I highly recommend them for any of the services they provide."

They were the only company I called that could come out immediately to look at the problem. Overall, I felt very comfortable with their HVAC knowledge. They answered all of my questions and left the jobsite clean after their work. I highly recommend."

" Update from 20 Jan 2026: I`ve been a repeat customer of Keep Smiling Plumber, Electrical, Heating and Cooling in the past for several home-related repairs. After having an unfortunate experience with Keep Smiling PEHC during my most recent service, I had some misgivings about the company and whether I would return as a customer. In regards to their customer service, everyone that I`ve engaged with (technicians, onsite supervisor, receptionist) has always been professional and courteous which goes a long way with me. The issue that I had was technical in nature and left me with some dissatisfaction regarding the quality of work. After speaking with leadership of this organization Mr. Powell and Ms. Amy ,I believe that they hold the highest standards and expectations for their employees and ensure that any work-related issues are duly addressed/resolved. I can sincerely say that they have regained my confidence and trust in contacting them in the future for my future HVAC, Electrical and Plumbing home needs. The manager I spoke with told me that there wasn`t any way the damage of the pump could come from the technician doing a drain and flush of the water heater. He told me that it would cost $1200 to replace the pump on the water heater. After speaking with the manager at Keep Smiling, I called another company which I`ve seen before in the community and spoke with a plumber and explained to him what happened. The technician at the other company told me that the pump could definitely be damaged if the pump was still plugged up and not turned off while the water heater was being drained and flush. I called the manager at Keep Smiling and shared those details with him and he replied that he understands what I`m saying but there was nothing he could do about it. I told him that I don`t have any reason to lie about any of this and felt very frustrated and cheated by the fact that I went in expecting for them to do a maintenance check for $59 for plumbing but ended up spending a $1000 for new.

"Outstanding company of real professionals. Work performed: 1. All power receptacles and switches were upgraded (new parts replaced old, wornout parts). 2. Assembled and install two (2) new customer supplied ceiling fans . 3. Provided and installed new 15A convenience 0utlet. 4. Provided and installed single pole 15A/20A arc fault breaker I have an eye for detail. Minor discrepancies leap out to me as well as minor work done well. Perhaps, twenty-two years in the military created this effect upon me. Sometimes it's a blessing and sometimes a curse as I find myself unable to accept minor, shoddy work. Example: All of the screws to the new face plates for receptacles and switches were oriented with the screwdriver slots in the vertical position. This was not done by chance by the team's three electricians but by their attention to detail and uniformity. If the small things are done perfectly, I feel it is safe to assume that all of the larger work is too. I have four more electrical projects to be accomplished and TE Certified Electricians will be my "go-to" company for these activities. I highly recommend TE Certified Electricians for your electrical projects."
