Outstanding Customer Service!!!!

The installation team from TE Certified Electrical, Plumbing, Heating & Cooling who recently installed my new heating & air unit and new ductwork work were simply top notch. Their customer service was outstanding. They explained everything that they were doing in detail for my installation. The team included Austin, Fernando, Brock & Lucas. I highly recommend these men. Also, I want to give a shoutout to my salesmen Fabian. He made my experience of purchasing a new unit for my home so comfortable and eased my stress. He fully explained the products I was purchasing. I highly recommend TE. I’m so happy with the service they provided, I even hired this company to handle of my plumbing installation.

Excellent electrical service!

Their technician Cody did an excellent job diagnosing and fixing the electrical problem. He explained the cause and offered solutions to fix it. While here he took the time to explain other electrical things to me and “watch outs” to be aware of. He was very professional!

Whole Home Surge Protector

I upgraded my home theater and naturally wanted to protect the investment from dangerous electrical surges. After researching the best way to protect home electronics, I determined whole home surge protection was the way to go. I Googled the average cost (about $500 to $1500), submitted an on-line request for quotes, and TE Certified was the first to respond. They followed up more than once and set an appointment. Andrew and Justin showed up on time, gave a quote that met my expectations, I agreed and they went to work. Additional professional advice was given regarding my panel, to which I agreed. All work completed within 3 hours at a reasonable price. We chatted as he worked, he explained the how and why of the safety changes, and I feel very good about the upgrades. Andrew was friendly, skilled, and very professional. Can I give more than 5 stars?

For this job, we performed a homecare inspection. We found a couple of issues, and the customer stated some issues they have found. We created a pick list, and the customer opted to go with a new toilet, replace the thermal expansion tank, replace 4 shut off valves, and replace the shower drain in the master bathroom. We are returning next Friday to finish the work. Thank you for choosing TE Certified.

For this job, the customer stated they had a leak coming from the dishwasher area. We checked all of the plumbing around the dishwasher, we checked the pressure, and thermal expansion, before turning on the dishwasher. There was no issues with the plumbing for, and around dishwasher. The only leak we found was what looked like to be the motor on the dishwasher itself. The customer also showed us an unrelated issue with the drain in the master, and guest bathroom. We found the issue was a mechanical vent in the attic which after testing showed it was tied to all toilets in the upstairs, and one on the main level. To fix the issue we tied the existing vent into the main 3 inch vent for the home. We performed work, and cleaned up. Thank you for choosing TE Certified.

I came out today because the home had failed the electrical inspection and the county had stated that the smoke detectors weren’t to code. The smoke and carbon monoxide detectors are installed to code but the inspector only tested one location and that spot didn’t have power. I discovered that the hallway smoke detector didn’t have proper voltage and found a buried junction in the attic. I then fixed the buried splice in the attic for the smoke detector circuit and replaced the hallway smoke and carbon monoxide.

While trying to remove the hose off the bibb the pipe broke off in the exterior wall. The homeowner’s brother in law was trying to remove the hose. We gave options and capping off the line was the decision. After the chemical weld was complete we pressurized the system and verified connection.

Customers three handle shower valve up in the kid's bathroom was leaking from the hot side. As well, their hose bib on the left side of the house as you're facing, the front door had a cracked packing nut, causing it to leak from the stem. Customer agreed to have the three handle.Shower valve rebuilt and the hose bib replaced with a quarter turn and a new emergency shutoff.Valve on the inside that was better located for easier access. Drained the house down and performed all said work above. I then tested by slowly turning the water back on and priming all of the air out of the lines and testing for leaks. The packing notes on the shower valves were a little tight on the diverter and cold water.So I loosened those up a little bit to the customer's satisfaction. Tested the hose bib for functionality and as well as leaks.No leaks, I left the hose bib winterized. Thank you for choosing and trusting t e with your plumbing needs

For this job the customer stated they had a possible leak coming from the washer box upstairs. Stain was visible in the garage ceiling, however customer capped hot and cold line to washer box which stopped the leak. Further inspection showed water pressure was 130 psi and a failed expansion tank. Customer also wanted upstairs tub spout fixed. We explained our findings to the customer and gave multiple quotes which included new washer box, new Prv, new expansion and new tub spout. Customer decided to move forward with the quote that included the tub spout, Prv and expansion tank. Other issues were noticed around the home presented and explained to the customer. Work was performed and thoroughly tested. Tank you for choosing TE Certified

Homeowner had leak upstairs which was fixed by another company. During this scope of work the pressure regulator was adjusted. When I arrived the water pressure was reading 20psi. In addition the thermal expansion tank was not functioning properly. Due to the age of the water I recommended replacing the relief valve for the water heater which is supposed to be replaced every 3-5 years. The garage disposal was said to be smoking during previous usage. Due to age these plumbing system components were replaced. After repairs were completed we tested. Verified with homeowner that they were satisfied with the completion.

Customer has an undersized electric tankless that was not producing hot water. Customer recently had his meter replaced by the county. I removed the cover and checked the impeller. I manually moved it and then tested the hot water. Hot water was restored. Left quotes to improve the water heater situation.

The customer was having an issue with the water heater located in the garage tripping the breaker in the main panel. The panel is a CH 150 amp main lug and the water heater is a 2p25 breaker located at bottom left of the panel board and is labeled properly. The breaker was in the closed position when I had arrived and I used an amp probe and did not see that any current being drawn. I noticed a disconnect by the water heater and it had a shut off switch and when I went to shut it off it started to sizzle indicating arcing was being produced. I shut the circuit breaker off and removed the cover on the disconnect and found burnt wires on the load side of the disconnect and the terminals were also burnt as well. This was caused by loose connections resulting in power loss, tripping breaker and damage to the disconnect. While the power was down I checked the termination point at the water heater and found that the wires were not twisted together and the bonding screw was not tighten do
