Returning Customer of TE Certified

I previously worked with TE Certified for an electrical repair and was pleased with their service. This was my first time contacting them for HVAC work and I worked with Albert Nah. I was impressed by the level of professionalism and expertise Albert brought to the visit. He completed a detailed diagnostic of my system, explained his findings clearly, and laid out all of my options in a way that made sense—no pressure, just honest guidance based on what the equipment actually needed and what my choices were. He identified issues that were overlooked by others, clarified what was necessary versus optional, and helped me understand both the immediate repairs and longer-term preventative steps. He was organized and transparent throughout. Additionally, to support his assessment and recommendations, he shared photographs of my equipment and gauge readings. His explanations were thorough and demonstrated a real depth of knowledge. It’s rare to meet a technician who delivers this level of clarity and integrity. TE Certified will continue to be who I call for major home system repairs.

Outstanding professional service

Paul Marquez, an exceptional TE technician, not only provided my regular maintenance servicing, also altered me to a growing problem with my HVAC coil which required additional repair for future optimum performance. I am grateful for his recommendation. As always, TE continues to provide outstanding professional service and I recommend them always.

Came out to relight the pilots on four fireplaces lit 3 successfully and recommended the homeowner to get a fireplace technician out for the 4th one in the basement. Fireplace by the couches seemed like it didn’t want to turn on but turned on by itself when we were about to leave so recommended the homeowner to check that one out too just to make sure it’s fine

Pressure regulator valve is an older style Watts single chamber with a blue tag. Shutoff valve is an older style gate valve. They are attached to CPVC. Replaced old watts single chamber with a new Watts 25AUB and replaced main shutoff valve with a new quarter turn ball valve. Water pressure in house is now 60 PSI. Showers were not getting very hot, removed handle and found that they were not adjusted, adjusted showers to a comfortable level for the homeowner. Homeowner also had a washing machine that had no water to it. I found that the valves for the washing machine were turned off. Valves for washing machine are quarter turn valves with water hammer arrestor
