Satisfied customer!

My technician Dani was courteous and professional. TE Certified made scheduling and payment for the job very easy, was able to get Dani out earlier than scheduled, and has been communicative during the entire process. I'm very satisfied with the work Dani did for us and will ask for Dani specifically to complete some additional plumbing work. Will be happy to recommend TE Certified to our friends and neighbors.

This is my second time using TE Certified for plumbing and I will continue to turn to them again if the need ever arises. Isaac was the gentleman who helped us this last time and I was very appreciative of him taking the time to explain what he found, what he needed to do and the speed and efficiency with which he completed his work.

Tech drives to problem call for basement system. Basement system is 13 years old. Previous technician was on site and found thermostat to be failed to which tech replaced thermostat with customer supplied google nest. On arrival thermostat was off the wall. Let customer know that to diagnose thermostat would have to go back on wall. Put google nest on wall and watched system. Thermostat would come on and off multiple times and not receive full power. Found system had an intermittent short on G wire that prevented system from powering on completely. Checked wires and used a different wire from green (orange). Customer agreed to thermostat replacement. Replaced thermostat with EcoBee thermostat and verified operations. Registered thermostat and registered smart sensor. Showed customer how to use thermostat in person and on app. Verified system was operational in heating/cooling and aux heat. 5 year warranty on thermostat and 1 year warranty in labor. Thank you for letting TE CERTIFIED

Rheem Proterra Hybrid water heater was displaying error code A108 for a blockage in the condensate line. Disassembled condensate outlet. Inspected inside of the unit in the condensate tray and found some sludge built up. I cleared the debris out of the unit and reassembled the drain line. I added a tee with a short stand pipe to the drain. Tested thermistors for faults. All readings were within manufacturer specifications. Thank you for choosing TE Certified!

Upon arrival customer stated that they were having a lot of dust issues upstairs system and wanted to have system inspected and wanted to have the downstairs system inspected as well. Did full evaluation of system, unit is 24 years old both gas furnace and ac/coil, and did find several issues In regards to customer concerns for dust. Blower wheel is very dirty, 12x20x1 system filter is u derailed for system and gets dirty fast, there is a conjunction box that return ducts feed into and the duct board inside is very dirty, duct system is very old and dirty as well, inside system insulation has a lot of dirt and dust build up. When system is running the dirt and debris is floating in air stream and system. The evaporator coils is rusted, the drain pan does not have any flood protection and does not fit the entire base of system, advised customer that rust from coils will clog drain line and there would be ceiling damage due to not having a long enough drain pan or flood protection device

Homeowner had been experiencing issues with the water heater. Prior to arrival the heater stopped producing hot water. After inspection and quick diagnostic gave estimate with different options. Homeowner decided to rebuild at this point. I replaced the upper/ lower elements and thermostats. Allowed for unit to heat and then tested.
