Our client was in need of our assistance in diagnosing whether she needed water piping insulated in attic or not. Client does not have water piping in attic and does not need insulation. However, the client had a high water pressure reading. I advised the client that the Prv needed to be changed to protect the fixture in home. The pressure valve was changed and I have a current reading of 60 psi. Our client is satisfied.

Tested system that was not heating for the main level of the home. System has been throwing an error code, saying that the pressure switch was not pulling in. Found that the control board was not sending any power to the inducer motor. Informed customer of finding and went to the supply house to grab the control board and replaced it today. Tested the system fully after repair and found no failures at this time.

Upon arrival technician found gas to furnace valve off. Technician turned gas back on to furnace to restore heat. Tech check filter 14x25x1 recommend replacement along with our Home Care maintenance plan, tech notice system hasn’t been serviced, tech talked with Landlord about furnace current conditions, tech found lots of rust and corrosion at heat exchanger. Heat exchanger is rusted throughout. Rust, scratches and corrosion can cause heat exchangers to weaken and develop cracks. By ignoring rust around your furnace, you could end up with dangerous combustion gases, carbon monoxide, sulfur dioxide and nitrous dioxide entering your tenants living space. I went over findings again with Landlord concerning these issues. Thanks for choosing TE Certified if you liked your technician service today don’t hesitate to leave a 5 star review!

Charley and his group member were really friendly and helpful. We were anxious to have our PRV changed, and they showed up as early as they could, which we really appreciate. Our PRV was installed in a difficult angle to work with, but they managed to have it fixed without further damage on the ceiling. It was a satisfying experience.

I had a great experience with Nolan Kangas of TE Electrical. I had quite a bit of work done from upgrading the service to my home, as well as the lighting and adding a Tesla charger. Nolan did a great job of communicating every day what he would be working on and cleaning up at the end of the day. I would definitely recommend him and TE Electrical.

We have used TE services in the past and trusted the service plus had great customer service. This time we had a water flow valve installed. The plumbers were super friendly and did a nice job. We had an issue with the electrician who wasn’t willing to fish an electric line from a different power outlet since the first one he attempted was blocked inside the wall by a horizontal stud. Felt very uncomfortable dealing with this electrician who eventually gave in and fished the line through a wall with no blockage. I don’t think I’ll be calling TE for electrical work in the future.
