Chad was great from the start. He was considerate of what we needed fixed and even added extra work which he was great about listening to our concerns and fixing other repairs while here. He was friendly and worked great with us and our dogs since they are inside. We appreciate all the time Chad spent at our home today and quality work he did. We’d recommend Chad if using TE.

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?

The customer called us out because he was experiencing gurgling in the upstairs. he explained to me a year and a half ago. He was running a drain snake and it got stuck inside the drain line. Today I did a camera inspection through the shower drain. Approximately 26 feet into the sewer line, I found the cable stuck inside the drain line. I discussed with the customer, their pressure reducing valve, their thermal expansion tank, their water heaters, and the benefits of an automatic water shut off and water filtration system. The customer is going to discuss with his father-in-law and let us know which option he’d like to go with.

Customer called us out for a clogged shower, clog in all upstairs sinks and a smell from the water. I tested the water and it was high in chlorine content. The wife and daughter’s sinks were both clogged, the sons had stung in the drain but was not clogged yet and the husband’s sink was clear. I recommended cleaning the ptrap and stopper for the three sinks that had stuff in them. Customer also wanted me to clean the one that was clear. I also recommended Endure for drain maintenance. I tested the shower and didn’t see it back up and heard the water leaving near the exit from the house. I removed the ptraps from all four sinks cleaned them and the stoppers. I put everything back together and tested the sinks. All were draining well and had no leaks. I cleaned throughly and treated kitchen sink with Endure.

Bottle of endure for preventative maintenance Customer was experiencing mainline blockage in 2nd floor, upon inspection we ran water for a long period of time and were unable to recreate blockage. The 2nd floor bathrooms were the only ones being affected. The cleanout had proper flow.

Homeowner’s water company alerted them that there was a water loss of 7 per hour. After checking toilets, I searched the crawl space to find a moderately sized pinhole on the copper piping spraying water on the HVAC system. I cut and replaced a 10ft section of old copper piping with pex. Tested and checked for leaks. Explained to the homeowner about the condition of the existing water piping and recommended a full repipe.

Customer has a hose bib that will not turn off. I gave her some options and she wants to wait until she can schedule her drywall repair man before we schedule the hose bib replacement. Just isolated the line today using the existing isolation valve.

Today I came out for 2 system inspection. Josh is selling the house on Monday and wanted me to do full inspection on both systems. Both the main level and upstairs furnaces have cracks in the heat exchanger. I did a carbon monoxide test and both floors have up to 4ppm of carbon monoxide leaking throughout the house. Both furnace capacitors are failing. Both blower wheels are extremely impacted with dirt and debris on fan blades. Both condenser coils are heavily impacted with dirt and debris. On of the outdoor fan motors is deteriorating on top. Both AC units come on and cool. I did a full inspection, but given the ambient air temperature is below 40 degrees I was unable to get any refrigerant pressure readings.

Only System - 2006 Rheem furnace System operational and home 72° on arrival. System is having intermittent heating issues. All parts in furnace are subject to failure at this age. The flame sensor and igniter are weak, the inducer draft motor is weak and over amping and the bearings are worn. The blower wheel is dirty and the blower motor is over amping weak. The heat exchanger is compromised with rust and metal fatigue. Due to the age, condition, and reliability, I recommend updating the equipment. After testing the heat cycle a few times the system was going out no flame detected. I offered to remove the flame rectifier, clean it and reinstall it. The homeowner opted for this option at the time. After completing the work I cycled the system through heat 3 more times and checked resistance on the flame rectifier. System is currently heating. Still recommend updating the equipment due to reliability. Thank you for choosing T.E. Certified, have a great day!

Tech was out for no heat. Turn system on thermostat went to furnace found that thermostat is not sending 24 V to control board tech jumper out thermostat wire. Verified 24 V is coming to the furnace, thermostat wire is good. Failed thermostat. Tech jumper wires on it thermostat found inducer motor not receiving 120 V. This is caused due to a failed control board. Also with system not running tech is unable to check all operations of system. Let customer know the following repairs that are needing to be done. There is no emergency drain pan under the system. There is no flood protection. Blower will need to be cleaned , drain line for the condensate pump is needing to be rerouted to the waste line Due to hot water coming from furnace water is freezing outside , condenser is needing a chemical cleaning. Also let customer know if she does go with control board and thermostat. Once system is up and running. Tech is able to test other components tech cannot guarantee that there is no other
