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.

So impressed with Isaac! He diagnosed a complicated issue with my plumbing. He was very detailed in his explanation of the problem and made sure I understood everything. He stayed late to make sure everything was working properly. My first call will always be to TE certified for any plumbing problems!

Performed 1 system diagnostics due to a noise complaint. I found that the furnace that is responsible for the noise was manufactured in 1998 and has a failing blower motor wheel that is responsible for making a loud noise intermittently. I also found that the blower motor capacitor is outside of the manufacturers specifications and needs to be replaced. The blower motor and wheel is also impacted with dirt. I used an inspection camera to look at the heat exchangers. I found that the heat exchangers are coming apart and I found were screws that old the heat exchangers together are falling out (see picture). I ran the furnace in heat mode for approx 20 mins and monitored the home for carbon monoxide; the furnace is leaking carbon monoxide into the home (see attached pictures and video). Carbon monoxide is dangerous to all occupants of the home. The furnace is not safe to operate. The furnace is also a potential fire hazard. I advised the homeowner about the issues with the furnace and ta

Customer called us out for a kitchen sink that was backing up. I inspected the garbage disposal and found lots of glass in it. I recommended doing a disposal reset and cleaning the ptrap to clear the glass that made it through. Customer agreed. I vacuumed out the glass and cleared what was stuck in the teeth and drains of the disposal by hand until it would run again. I then removed the ptrap and cleaned it out. I reinstalled it and tested the disposal and trap throughly for any leaks. Customer said he might want to replace the disposal soon so I left two estimates for him.

1 of 2 Rheem Tankless water heater was flashing code P1. Homeowner moved in about a month ago and did not know of its service records. Went to flush both heaters but the one throwing the P1 code didn’t not have service valves installed on it. Flushed the heater we could and cleaned the filters in both heaters. Brought the issue of no service valves to the customer and the improper piping of the heaters and the customer decided that they would like the heaters repiped properly. Installed service valves and repiped the water lines in proper sequence. Flushed the water heater we could not flush earlier. Checked Kohler shower cartridge. It needs to be replaced in master bathroom

No heat basement. Found system turned off. Upon arriving turned on. System appeared to operate but is very loud. Upon inspection found cracked heat exchanger, high amp draw on inducer motor, weak run capacitor, dirty blower wheel, high limit was tripping.. found system to be leaking carbon monoxide into basement. Upon trying to price repairs was notified parts no longer available for system as it is 25 years old and not in production anymore. Furnace needs to be replaced. Informed customer. Customer wants quote to replace furnace. Informed customer of crack in heat exchanger and that it was leaking carbon monoxide. Advised due to safety concerns not to operate the heat. Left thermostat in off position.

We installed water clamps and ground wire to bond hot and cold water lines at the water heater as per inspection report. As a courtesy we also installed a bonding jumper at the prv. This was not on the inspection report, but is necessary for a complete grounding system. We installed a junction box in the walk in attic by the furnace to correct the flying splice. We secured the box, stapled the wires, spliced wires inside junction box, and installed a cover plate for the junction box.
