Excellent & Dependable Service

Austin Newman is a trustworthy plumber. During the coldest days this winter, our water heater broke down and we only had bone chilling cold water. Austin took care of calling Rheem to order the needed parts. He prioritized us in his schedule and when the needed part arrived at their company, he promptly installed it the following morning. Now we have hot water again! I highly recommend TE Certified for reliable plumbing and HVAC repairs.

Great Experience!

Joshuia showed knowledge and caution with his work. He let me know what to expect and provided a completion ETA. When posed with risky challenge of a thin toilet connection, he calculated that he may need support of another technician rather talking on a potential risk of it breaking. P

Cole did an excellent job upgrading my kitchen lighting today. He also installed outdoor outlets that I really needed. I had been running extension cords through the garage and basement for Christmas lighting. It was truly a “Griswold Family” moment when all the Christmas lights came on without all the hassle! Now I have safe lighting, professionally designed. Cole is a pleasure to work with and I will definitely call him again when needed.

Very Satisfied!

Jeff and TE Certified is the most comfortable I ever felt with any plumber. He assessed my plumbing issues and thoroughly explained them. He was honest with what was going on, and how long the work would take. In another note, i personally attempted to replace a shower cartridge but forgot to put the locking pin back in. I mentioned it to Jeff the morning he arrived, and before he did any scheduled work, he told me the urgency the pin needed to attached , he he went of his way to attach the pin. I am greatly satisfied with Jeff’s knowledge, work, and helpfulness.

2020 Goodman 90% furnace System making a gas smell near exhaust vent outside. The system is intermittently working, the pressure switch and control board are going bad. The system will cut power for a split second to the gas valve and the flame goes out, when the valve comes back on, raw unburnt gas flows through the system. I jumped out the pressure switch and the system ran for a few minutes the went out on a high limit fault. The high limit never opens though. The board will give off random error codes at times. Recommended replacing board and pressure switch. Thank you for choosing T.E. Certified, have a great day!

We were called out for the following issues: 1) The customer had questions about a blue light on the tankless in the garage that we installed in 2021. I explained that this was a normal status light on the Rinnai WiFi controller. 2) The customer was unsure of which shutoff valve shut off the rear hose bib as it was moved during a halo 5 filtration install we did in 2025. I showed the customer the shutoff valve and installed a valve tag. 3) A toilet we installed in 2021 was occasionally running. We found a failed flush gasket, most likely due to in tank toilet bowl cleaner. We replaced the flush gasket seal on the toilet. We advised the customer to discontinue the use of in tank toilet bowl cleaners.

For this job, the customer showed us a gas water heater which was vented into the chimney of the house, and wanted it replaced. We gave multiple options on replacement, and the customer opted to go with the 50 gallon power vent. We ran installed the heater up to code, and tested the equipment, and work we did. Once complete we cleaned up, and double checked everything again. We left estimates for removing the pvc, and cpvc water lines in the house, as well as removing the cast iron in the basement m and moving it to a different location to add room in the basement. Thank you for choosing TE Certified.

Service call for water leak. Leak is around vent in basement. Visual inspection found 90% furnace in attic and draining to washer box on upstairs floor. Inspected drain termination point to verify that was the actual termination point. Camera inspection area around vent where leak is present. Could not find source of leak as there is no plumbing in the joist space around the vent. Scheduled plumber for 1/31/26 @ 9am-12pm. Signed customer up for 1 system HomeCare. Leak is more prominent when furnace is operating.

Customer had a garbage disposal that was completely rusted out. Power was making it to the disposal, but the disposal wouldn’t turn on after diagnosing i pinpointed it to be at a disposal rusted out , the disposal was jammed at all , blades just wouldn’t spin , so we ended up replacing the garbage disposal with the badger five and sinker three-quarter horsepower, and after testing the disposal worked perfectly with no leaks and no backups

Main level not keeping temperature set and works longer. Found filter very dirty and it could have been the cause of not heating properly. Inspected system. Heat exchanger with some hot spots and compromised, flame sensor and igniter showing signs of wear and tear, return plenum covered by dust and biological growth and single capacitor going weak. Furnace is 23 years old, and passed the life expectancy for a system. Also, heat exchanger is compromised and air quality in the house poor and compromised. Sent estimates for potential repairs (not recommend). At this age and conditions, the best option would be to upgrade both furnaces, for a variable speed furnace with 10 years warranty, and WiFi thermostat. Set a lead to quote upgrading for both furnaces for today.
