Albert as always was very professional and thoughtful and polite. Even I have to change my furnace, he didn’t make me feel too bad. He introduced several new things from company, probably I am interested in that too. Thank you.

Leak in front yard near the meter. Upon initial inspection I could see where the water was bubbling up through the ground. Performed a leak search and found the leak. The leak was coming from a compression coupling from a previous repair. Removed both of the couplings and replaced with PVC pipe and fittings. Pressurized, checked for leaks, and returned the home to service.

Perform a systems home care maintenance. Change filter, tested all electrical components, flushed drain line, tested thermostat, Tested both system on cool and heat, checked pressures and refrigerant. System is working properly at this time, however notice biological growth is spreading around duct work, highly recommend to add a germicidal device to the unit to stop the spreading and purify the air. Costumer decided to move forward with enhancement and repairs, work was done and tested. Thank you for choosing TE Certified!

Installed Grundfos Alpha HWR. Drained down water heater in order to remove existing recirculation line tied into the bottom. Removed old pump and replaced it with a new Grundfos. Tied recirculation line in cold inlet in a manner that would better serve the parallel design of water heaters. Added check valves in correct locations on recirculation line and cold inlet. Tested thoroughly and ensured customer was receiving proper hot water recirculation.

Installed two client supplied pressure assist toilets in the upstairs and downstairs men’s room. The downstairs toilet flange needed to be replaced. Both toilets are functioning properly at this time. Completed minor repair on both Delta single handle lavatory fixtures in the men’s room downstairs. Repair included new seats and springs for each. Both are working properly at this time. I was unable to replace the thermal expansion tank due to the CPVC ball valve not turning.

Upon arrival and approval, we began the previously discussed work of installing a new shower cartridge in order to eliminate the cross connection. The manufacturer misidentified the cartridge and we purchased the wrong cartridge. We were not able to replace the cartridge. I had called the manufacturer and they did not answer and put me on a callback list. While I was waiting on the callback, I went ahead and emailed them the picture 30 minutes later they called me and wanted me re-email the picture to them. This is when they miss identify the cartridge and we ordered the wrong cartridge. This separate email that I sent was responded to a day or two after ordering the incorrect cartridge. The email had a link to the correct cartridge. We are sending the correct cartridge information to the customer as well as the manufacturers phone number so they can call and order this cartridge. This is the most cost-effective way for them to obtain the cartridge. The shower with the failed shower

Jim called us to the home today because he had some issues with the lighting in his kitchen. During his process in the remodel, they removed a cabinet, exposing wire. We replaced all old can lights in the living room room with LED wafers. He also replaced the old globe lights with LED wafers. As well as installed a new wafer above kitchen sink. We will be returning next week to replace federal pacific panel.
