Awesome Service!

An emergency occurred in which our hot water heater burst resulting in our basement flooding. After receiving an outrageous quote from a company that had previously done work for us, we searched online for plumbers in the area and ran across TE Certified. The Google reviews were so impressive that we contacted them. The customer service that we received was great. Paris, our technician, came out that afternoon. During our consultation, Paris was very professional, informative, and personable. He clearly explained the service that needed to be done and answered all of our questions, which were many. We are more than pleased with the work that Paris did. As a result, we will not hesitate to contact TE Certified for future services.

Job well done!

Repeat customers, and once again Andrew was a complete professional, and a pleasure to have in our house. The work wasn’t easy - pulling new lines from the basement to the attic, or the equivalent of 3 stories - without cutting any holes in existing Sheetrock. The work was done quickly and thoroughly cleaned up afterward. Excellent job!

Completed homecare visit today in single gas system in attic. Inspected ductwork, filter, flushed drain line and tested heating operation. Checked gas pressures and adjusted to manufacture specifications. Tested electrical components, took amp draws and verified system operation from thermostat. Inspected outdoor unit electrical, refrigerant levels and checked condenser coil overall condition. System is zoned with a 14" and 8" damper for one zone and a 12" damper for upstairs. The 14" damper is getting stuck, not opening all the way once it closes. Zoning system is missing D.A.T.S., discharge air temperature sensor, and missing a bypass damper. Return ductwork is undersized with 920cfm but 3 ton system requires 1200 cfm. Total repairs listed as follows, installation of 12" bypass damper, discharge air temperature sensor, 14" damper replacement and adding a 12" return to ductwork. Inadequate flood protection on attic system. System is operational at time of service.

Upon arrival spoke with Mrs. Nancy about a leak under her kitchen sink. She chose to move forward with a rebuild of the drain system under the sink. Thoroughly tested the sink and no drips or leaks were observed. Was able to identify Mrs. Nancy’s rear hose bib shut off as she was unable to find it left quote to replace hose bib gate valve with a new quarter turn ball valve.

The customer had a new light fixture he wanted to be installed in the garage ceiling and the garage door opener was attached to the fixture via a socket/plug adapter. The homeowner is aware that with the option he picked, the switch in the 3g box located by the garage door has to remain on for the garage door to work and in doing so will keep the overhead light on. I removed the old light fixture and installed a box by the light and garage door opener, installed new wiring, a junction box, an outlet and plate. After completing I installed the customer supplied fixture. I went to the panel and supplied and installed a new GFCI breaker on circuit #2 on the panel board. I took the existing circuit from two and moved it to 15b. The existing wire from 15b was the garage and that got moved to the #2 After installing I turned the breaker on and tested the light fixture and the garage door I suggested to the homeowner about having GFCI (Shock Prevention) devices installed in the followin
