We are extremely pleased with TE's service! Adrian Parsons and his team did an excellent job from start to finish. They arrived on time, were systematic in analyzing our generator needs, answered all our questions, and worked efficiently. They were good-natured, personable, and respectful.

Thorough diagnosis!

Jonathan came to my house on time was super polite. He's like very observant like a calculating engineer with high attention to detail. He caught small things like a loose thing that needed to be taped up and noticed the measurements on my ducts that needed to be changed to be more efficient with the air supply. I wish all HVAC technicians are as skilled and competent as him

Great service and reasonable cost

I finally got my exhaust fan installed and Johan did a great job. He was on time and communication was consistent. I won’t hesitate to use TE Certified services again.

The message from the office on the schedule change was spoken very fast and was hard to understand. Please slow down, so people can understand the message; it's not a fire drill.

Good Job not great customer service

Five stars for the electricians. Three and two stars for office customer service via text and email without the ability to speak to a human, ask questions and get more clarification prior to the job. The on-line scheduling tool did not account properly for the amount of time or align with the quotes thus only half the work was performed. Thus lower score for convenience.

Upon arrival tenant advised me that heat was only blowing cold air and was coming on and off. After inspection of system found that system had a failed heat exchanger. Unit is 33 years old (1993) both ac and heat. Duct system is in very bad shape, there are a lot of duct runs with holes inside them and insulation is showing on the duct runs. Inside system blower wheel and motor are very impacted causing air flow to be very minimal inside system. The high limit is activating due to furnace temperature exceeding 155 degree that rated on data plate. Temperature is reaching 170+ and activating high limit switch. Plenums are very dirty and need to be updated. Tenant stated ac unit struggles a lot durning summer, the evaporator coil is very rusted and potentially leaking refrigerant. Spoke with landlord in regards to issue with equipment. Recommended rep placing full system both heat and ac and also replacing the supply plenum, return plenum and duct runs. Customer approved to speak with ins

Performed 1 system heating diagnostics on an out of warranty carrier heat pump/ air handler. I found that someone had disconnected the compressor plug for the outdoor unit. I replugged in the compressor and the breaker tripped. The home had stated that the unit had been diagnosed with issues at the end of last summer. I checked the contactor and capacitor and verified that they were ok. I checked the breaker sizes. I inspected the air handler in the crawlspace and found that the evaporator coil was clogged with hair and it looks like the TXV bulb was potentially damaged during the installation of the system. I gave the homeowner pricing for the repair and emailed him an estimate. The homeowner discussed it with his wife and they would like an estimate to replace the system.

Customer had a mainline blockage in the yard. It has two outside cleanout in the yard. Customer said the main line was replaced about six years ago, the whole house was backed up, so I gave the option to run the cable through the outside cleanout, have to run a cable I was able to clear the blockage. I advised a customer that would be best to have a camera inspection to see what was happening in the main lime if it was just tissue paper, getting clogged or roots or bellies etc , after testing the entire house the drain is flowing normally now with no back ups camera inspection scheduled for tomorrow morning

Gasket material found inside inducer port where condensation is removed at collection box. Some leakage is there and possible replacement of inducer motor could fix this. Also leaking at silicon joint where 2” pvc meets up to pipe of inducer exhaust. Black pipe of inducer is cracked. Silicon alone may not seal leak. Call in a few days to set appointment with an install supervisor to discuss a new furnace option.
