I can’t say enough good things about James Steffey. The repairs to my home were extensive in difficult circumstances. His professionalism and expertise as well as his excellent communication skills made an unbearable situation more bearable. I feel extraordinarily lucky that you assigned him to me and look forward to trusting him for future work. He is a true leader.

JT and Dylan came out to service our toilets. They were both knowledgeable and thorough. They checked out what we thought was a problem and luckily it wasn’t. They installed another toilet quickly and efficiently. We will use TE Certified again for sure.

Warranty swap the gas control valve as it has failed. Drain the heater, swap the GCV test for leaks. The hub drain is too close to the trap, increase the vertical length and adjust T&P discharge line accordingly HVAC will need to come out to re route one of the condensate lines with a pump. Expansion tank is still holding air, but is getting there in regards to age these units typically last 6 to 7 years and the one that’s in there currently was installed in 2021. Replace expansion tank and have it properly bracketed

Upon arrival I was pointed to the master bathroom sink where the pop-up assembly had broken. I was also pointed to the master bathroom toilet, which was rocking. During our safety inspection of the home plumbing system we discovered a leak on the water heater. This leak is coming from the weld seam where the element connects to the tank. After providing options and upon approval, we replaced the sink pop-up assembly. We also pulled the toilet and confirmed that the flange was not broken, reinstalling the toilet, and properly shimmed and silicone the toilet. We gave the customer a leak alarm in the event that the leak gets worse. Tested everything for leaks and proper function

During our visit, the customer mentioned they had a water heater that was leaking and wanted a quote to replace. Upon inspection, I noticed they had two water heaters. They were installed in a series and the left unit was leaking. I spoke with the customer about a few different solutions. Multiple estimates were provided and presented. An estimate was approved for replacing both water heaters. The 13 year old tanks were replacing with two new 50 gallon gas water heaters. Each water heater received an anode warranty extension kit. This increased the manufacturer warranty to a total of 10 years. A new grundfos Alpha recirculating pump was also installed. The customer downloads the Grundfos go app and I helped him setup the pump. The customer is aware that the water heater venting is not up to code. One of our hvac techs provided a quote to correct the venting. The customer is responsible for making the decision on proceeding with their quote or not. While installing the water heaters,

For the master bathroom we completed a full re-wire to include: Installed a new 15 amp circuit for the master bathroom. We removed the recess lighting in the basement and fished a new wire across the ceiling and up into the master walk in closet. In the master closet we installed a new cut in box with a blank plate in order to get the new circuit up. We went into the walk in closet switch box and jumped out to the smaller closet, then to the toilet area and then to the 3g switch box. We also installed a new power supply to the smoke detectors in the hallway. We supplied and installed new boxes, switches plates annd one outlet in the walk in closet. With the new switch legs we provided and installed (7) new wafer lighting and (2) bath fans we wired in all new switch legs to each new fixture that we supplied. After installing and wiring everything up we restored power and tested everything to ensure it’s working. We made sure to clean our mess up to the homeowners satisfaction.

Homecare inspection. Checked electrical components, checked ductwork, checked safeties, checked blower wheel and cabin, flushed drain, added safety switches, taped up broken flue until we can get back to replace it, tested operations at thermostat. Found broken 10 inch flex run, unable to access flex and pull it out enough to reconnect, wall may need to be cut open inside or in utility room in order to make repairs. Flue vent pipe being single wall is still code in this situation but pipe itself has a crack in it. Need to replace 5ft piece of 4 inch single wall pipe and 4 inch elbow. Collected deposit for safety switches today, advised customer the rest will be collected when job is complete. Plumbers moved water heater in order for hvac to make repair so we need to return tomorrow, customer agreed to not have hot water until work is done. Completed Homecare today.

Arrived ed for no heat in lobby area. Inspected Carrier furnace electrical, gas components, filters and heat exchanger. Furnace was flashing fault code for high limit switch. Carrier furnace labeled #1 had a filter stuck in blower motor. Filter was very dirty and nothing to hold it in place which led to being pulled into blower motor. Also found a failed heat exchanger as seen in images from surrounding insulation burning to a cracked ring. Beginning section of single wall 4" flue pipe is installed upside down leaving air gaps around crimping for co to leak out. All flue vents for either furnace and water heater are single wall pipe and show rust through out flue. CO detector is picking co levels in utility closet possibly from flue condition/installation and failed heat exchanger or both. While in utility closet faint smell of natural gas was noticeable. Found gas line goin into water heater was leaking and recommended immediate repair. Inspected furnace #2 that showed no issues while

Replaced old sewer pump with a new 1 hp grinder. Installed a new lid. Repiped as needed. Tested for leaks and function, all good. Due to the location of the pump being outside of the heated envelope of the home, there is a risk of freezing and damage to the pump. No warranty on pump or piping. Thank you for choosing T.E. Certified.
