Jonas did a great job troubleshooting and replacing our main meter box. He found several other problems that needed attention and got our home up to code. He arrived in a timely manner, kept me informed of his progress and was a total professional.

Wonderful Experience!

Stephen was wonderful to work with. He was very knowledgeable about the installation process of installing gas and replacing a couple of leaking valves. He was able to do things on the fly adjust accordingly when necessary and had a great attitude and I’m a wonderful personality. Highly recommended. Thank you so much for a wonderful and easy install.

Always Reliable Service

Our heating system was not working. We called for an appointment. We were notified early morning that a tech was coming to help. The service for our heating system was done by Koi P. He was professional and advised us of all the issues we may have. He got our system to work but advised on what our options are moving forward as our system is 10+ years old. We used TE certified for our plumbing, electrical and now our HVAC system. We moved to GA from NY over 2 years ago and would recommend TE Certified for all our home needs!

Charles Mays came to my house to repair a plumbing leak and replace parts of my water lines all in my crawl space. He worked hard all day. He was courteous and professional and got the job done. Then he gave me a walkthrough and showed me everywhere he had worked. Didn't get that from other companies. Very satisfied.

I was called out to Felix & Blanca‘s house for a heating issue. Upon my arrival Felix let me know that the thermostat was constantly heating the house well above what they wanted it. During the evaluation we discovered the thermostat was reading well below what the actual temperature was causing it to heat well above where it was actually set to. I adjusted the calibration it it didn’t get to the correct temperature so I contacted ecobee and they confirmed the thermostat was malfunctioning. We also saw that the flue pipe is outdated and installed incorrectly.

Arrived on site to troubleshoot flickering lights in the office. I checked voltage at main panel and outside equipment. Voltage coming in is steady and correct. I checked connections at the main panel and outside equipment. Everything is tight with minimal corrosion. They do have a power back up they were using. Once they unplugged that, the flickering lights stopped. I recommend investing in a new battery backup. I also recommend getting the power company out to test their wires. I did recommend install surge protection for all electrical panels in the office. Everything is working upon departure.

Homeowner has a yard hydrant with a dresser coupling that is leaking from the dresser coupling. The riser for the hydrant is galvanized. Informed the homeowner that there is no guarantee a repair is even possible on this. Informed the homeowner that galvanized should not be on potable water systems, and that the smartest option would be to install a new, code compliant yard hydrant. Homeowner wished to attempt a repair at first. Dug down about 6 inches and found the tie in for the yard hydrant. Tie in is a galvanized tee on a galvanized water service. The tie in tee for the riser is pointed straight up, branching directly off the water line. Informed the homeowner at this point that any work attempted is permanent, and there would be no ability to undo anything from this point on. Homeowner wished to continue. Removed old dresser coupling and hose spigot. Installed new dresser coupling and hose spigot off a brass nipple. Pressurized system and tested for leaks. No leaks at the time of
