Outstanding service!

I have lived in the same house for 28 years and this was the best plumbing service I’ve ever experience.

Such a helpful professional!

As well as addressing our immediate concern (a “frozen” hot water supply valve), Allen Murphy quickly recognized a secondary issue that was creating low hot water pressure to the rest of the house. He explained the situation clearly and succinctly. I am (again) extremely satisfied with the professionalism, knowledge, and friendliness shown by TE Certified team members in all of my experiences with them!

Stephen & Steve both came to work on my plumbing needs. Both men were very professional & courteous. They came in, did the work & cleaned up after themselves. A good experience.

Excellent service!

We needed to replace an old water heater that stopped working and was beginning to leak. We replaced it with a tankless heater and it was a complicated installation for a variety of reasons. Josh did fantastic work with close attention to detail. Everything was precise, including the cleanup when finished, and it works great.

Came back to do repairs and enhancements, added a new transformer, cleaned evaporator coils, added 2 damper to upstairs unit, install 2 ApcoX, replace old condensate line for downstairs system and reset system. Unit was working properly for a while. Right before I left homeowners house I notice that thermostat was showing an error code, so checked system again and after my finding a notice that smart hub and zoning system suddenly failed. Smart hub is discontinued so needed to upgrade Lennox thermostat that doesn’t required smart hub and replace the zone board. Costumer parts are under warranty so drove to Lennox facility to get the new parts and move forward with repairs. Tested system for a long period of time to make sure nothing else came up and system is now working properly. Thank for for choosing TE Certified!

Performed quoted repairs on the dryer vent. Used a large piece of plywood to lay across and used a sawzall to cut into the “old roof.” Used a new 90 and connected all pieces of the dryer vent that disconnected and ensured they are secure. Also performed an electronic leak search on the master bedroom HVAC system, but couldn’t find a leak at the indoor coil. Added about 0.8 lbs of R-410A slowly into the system to see how it reacts. The system seems to be low on refrigerant. Built follow-up estimates with the customer. Reported results to the customer. Scheduled to return next Monday 8-10 to perform a leak search and condenser coil cleanings.

Blower wheel is clean inside the cabinet is clean. Outdoor unit inverter board did not show any active error codes, condenser coils are clean. Advised customer that drain line is not draining properly and backing up. The line goes through chase of wall and then meets a tee in crawl space with other units drain.

Customer called us out for two drains that were stopped up. There was a drain in the upstairs, master bathroom, shower, and the downstairs basement tub that were both draining very slowly. I will have to snake the drain in the upstairs master bathroom shower. I will also have to snake the drain in the downstairs basement level tub. I was successfully able to remove stoppage. Everything is draining properly at this time. Customer is very satisfied.

We came out today to install the Grounding Electrode System on the home along with a full home surge protector. -Grounding Electrodes Conductor- We installed one grounding electrode from the main breaker CH panel across the basement then dropped come recess lights in the finished portion of the basement and over to the PRV and jumped it along with making contact within 5’ of entry. We installed another grounding electrode conductor from the main breaker panel over to the exterior wall by the back door and went outside to the ground rods. -Ground Rods- We installed (2) 8’ rods into the earth past the new deck to allow rain to make contact to the rods. I preformed a Fall Of Potential test on each electrode to see where the resistance value was at. *Rod by the fence 48.3 Ohms *Rod closet to the home 51.2 Ohms I then ran a temporary bonding jumper between each new rod in parallel and the resistance value dropped down to 27.7 ohms. After bonding the hot and cold at the water heat

Inspected complete system found cracked heat exchanger on furnace located in garage show client and turned off at thermostat. Inspected all electrical components and connections found weak 10 mfd run capacitor on furnace reading 8 and one for condenser fan motor on ac 7.5 reading 5.5.
