Great Service

I had a great experience with TE Certified Electrical, Plumbing, Heating and Cooling. Blake was professional, on time, and a pleasure to work with. He did an excellent job repairing a leak in my hot water heater pipe and went above and beyond to protect my home—carefully draping plastic over my furnishings and carpet. I truly appreciated his attention to detail and respect for my space. Highly recommend!

Our service professional, Chad, was communicative from the beginning. He fixed the problem immediately, even when the company that caused it could not. He explained in detail what the issue was. No hassle, no selling us anything. He did the job perfectly. Thank you Chad, my family and I appreciate you.

Diagnostic Upon arrival, met with homeowner and he showed me flood issue in the basement. This is for the main level system. Upon visual inspection found soft condensate line to be completely not attached. Customer approved inspection on system and tested system. Outdoor unit has a condenser coil that is very dirty. Outdoor unit also has a capacitor that is testing 3.7 on a five. This is roughly a 30% failure and should be addressed ASAP. This will lead to a breakdown in the near future. Upon inspection of the furnace area found filter to be very dirty. Replaced it with filter that was sitting right beside the unit. Blower assembly is slightly dirty. The evaporator coil shows lots of biological growth and mildew on bottom. Pictures attached. The system has no UV protection. This will help keep this biological growth at bay. The system also has very minimal flood protection. An in-line drain safety is all there is. System has no drain pan. Recommend adding a wet switch to keep this iss

Return trip to search for source of water leaking into the living room. Cut access in the ceiling to inspect the area where the water damage is showing to potentially locate the leak. Once the ceiling was open, ran water, splashed water on the walls, overflow, and trim for extended periods of time. The homeowner had someone take a shower in the tub while we were here and could not detect any water leaking even though the drywall is wet, and evidence of leaking is present. At this time we have concluded that the plumbing is not leaking and the water must be either coming from the tile, roof, or outside wall. Just

After a diagnostics found that the system is low in pressure, search on the condenser couldn’t find any leak, leak searched on the evaporate coil and found a leak at the bottom of u-bent.
