Excellent Service

When I first moved into my home a friend recommended Knight Air. They were a family owned business, honest, reliable and reasonably priced. I’ve used a few different companies since they sold their business. I think I finally found my new company with TE Certified. I received a text from Jonah with his picture, introducing himself as my tech and telling me when to expect him. He actually showed up early. He was polite and professional and respectful of my home. We talked about the problem and the age of my units, then he went to work. He informed me of his diagnosis and I authorized the work. He later presented me with a written report of the work he’d done and recommendations for options I might want to consider. He was the consummate salesman - personable without being pushy. I declined his recommendations but I did sign up for their maintenance plan. He informed me that the previous tech had installed filters that were too small so he replaced them with the proper sized filters. I learned they also have certified electricians and plumbers. From my experience with Jonah I highly recommend TE Certified for your HVAC needs.

The homeowner was receiving lukewarm water throughout the house. I checked both water heaters: the tank water heater was set to 130°F, while the tankless water heater was set to 120°F. The issue arose because when the 50 gallons of hot water from the tank ran out, the 120°F water from the tankless heater mixed with it, resulting in lukewarm water. To resolve this, I adjusted the settings on the tankless water heater to allow it to increase up to 140°F. However, at the homeowner's request, I set the tankless heater to 130°F, informing them that this setting could be adjusted. I noted that I do not recommend leaving it at that higher temperature, especially considering that the code minimum is 120°F. Additionally, I observed that everywhere in the house, except for the master shower and the daughter's shower, was receiving lukewarm water. I advised the homeowner to replace the cartridges in these showers. The homeowner has ordered a specialty Delta cartridge, and once it arrives, we

Today Kelly has called us out here because she has water filled in her meter and water is currently leaking in the general vicinity. When doing further investigation, I could hear water leaking in the ground in front of the water meter. Advise that leak is most likely digging it up to get down to it and identify what the piping is. Buried the crown to expose the water main service where I found that it is leaking from the soix chief fitting connecting to the irrigation. Kelly asked us to not reconnect to the irrigation because of the amount of issues that they’ve had with multiple leaks. As requested, I reconnected the main service line and capped the irrigation line to terminate irrigation service. Turn water back on and tested for leaks found no issues.

For this job I came to see a water leak in the yard, home owners recently noticed puddling around side of the home. We traced it back to the entry point of where the water was entering the home. I dig an exploratory dig and found the leak at a 90 fitting. The fitting looked cracked from age and ground settling. I removed damaged section and installed new pvc fittings. I pressurized system for 15 minutes to ensure there were no more leaks. Back filled the hole and covered up with pine straw.

Arrived and found that the upstairs master bathroom shower is constantly dripping and won’t turn off. This is the only faucet in the home that is dripping. House water pressure is currently at 75psi which is indicating that the pressure reducing valve located in garage beside water heater is old and starting to fail. Highly recommend replacing prv as soon as possible. Advised customer of possible issues that could occur if the high water pressure is not addressed soon. Customer understands high pressure can damage plumbing parts/fixtures and agreed for me to go ahead and replace the shower cartridge now and he will call us back asap to replace the pressure reducing valve. Installed new delta grey cartridge and is working properly and not dripping.

Customer called about a wet spot on the ceiling in the guest bedroom which is directly below the master bathroom. Performed leak search and cut open ceiling in guest bedroom. Discovered leak coming from the shower valve in the master bathroom. The shower valve is a specialty one and will have to be ordered. For the time being, hot and cold lines going to master shower valve are cut and stopped to stop current leak. Wall in master bathroom toilet area behind shower valve had to be removed in order to access shower valve area. Shower valve is being ordered and a return visit will need to be scheduled once the shower valve arrives. Cleaned up from cutting drywall Turned water back on and tested work. Everything is working as it should at this time. Thank you for choosing TE Certified
