Jonas did a great job troubleshooting and replacing our main meter box. He found several other problems that needed attention and got our home up to code. He arrived in a timely manner, kept me informed of his progress and was a total professional.

Wonderful Experience!

Stephen was wonderful to work with. He was very knowledgeable about the installation process of installing gas and replacing a couple of leaking valves. He was able to do things on the fly adjust accordingly when necessary and had a great attitude and I’m a wonderful personality. Highly recommended. Thank you so much for a wonderful and easy install.

Replace existing water heater with a high efficiency Navien 240A2 tankless water heater This tankless provides endless hot water and has the capability for hot water recirculation which provides faster hot water Installation includes: new water heater, new thermal expansion tank, new upsized gas line and gas whip, new sediment trap, new shut off valve for water heater isolation, and vent work required for tankless conversion Manufacturer recommends flushing a tankless annually unless a water conditioner is installed prior to the tankless which increases time between flushes up to 5 years Includes removal and disposal of old water heater This estimate is for plumbing only and does not include any electrical work to install an electrical outlet if necessary for tankless and condensate pump to plug into Tested all work and everything works as it should at this time. Thank you for choosing TE certified.

Homeowner had issue with upstairs bathroom not properly regulating water temperature. I gave homeowner option to replace the valve due to the existing valve does not pressure balance. We replaced the valve with new Delta multi choice. In addition there was previous work that needed to be addressed. The pressure regulator was replaced and the thermal expansion tank was installed on a bracket. System was pressurized and checked with homeowner for satisfaction.

Today Addison called us out to his home because he had a few pick list items that he wanted to go through. Today we only did a troubleshoot for the master closet, light and installed ceiling fan and master bedroom.

Today I replaced two outlets in the living room. I replaced two light switches in the master bedroom. I ran a new number 4 bare ground wire from the utility bonding bridge to the backyard where I mounted a new bonding bridge on some ham radio equipment. I ran number 10 THHN jumpers from the new bridge to bond multiple parts of the ham radio equipment.

Home owner pointed out area of gas leak found by gas company. Located gas leak with soap bubble leak detector. Took apart and checked fitting condition and then tightened fitting down. Fitting is no longer leaking. Home owner is selling home, so he didn’t want me to do a full inspection at this time. Turned gas on and reset furnace. Checked furnace operations.

Customer called us out for a dishwasher that wouldn’t drain. I inspected the connection to the sink drainage and it was hooked up to the garbage disposal. The garbage disposal was draining with no issues. The garbage disposal had minimal signs of wear or rust. Customer had not other drainage issues. Water heater had no leaks.

No Heat - 25+ year old Rheem System not heating due to age and multiple failures. The blower motor has failed, the heat exchanger has failed in multiple areas, the inducer motor bearings are shot and the inducer motor is over amping. The blower wheel is 100% impacted with debris, the evaporator coil is 100% impacted with debris, and the flame rectifier is weak. The high limit is burnt and blackened due to the system has been over heating for a while. The AC operates on R-22 refrigerant and is also not working. Due to the age, condition, and not all repairs eligible, I recommended updating the equipment. Also the water heater vent pipe is not properly installed, there needs to be a 4-3 reducer. Right now the 3” water heater vent pipe is stubbed into a 4” opening with tape around it. Pictures and video attached. Thank you for choosing T.E. Certified, have a great day and happy new year!
