Old disposal was leaking from the bottom , told the customer we would have to replace , replaced it with a 3/4 horsepower insinkerator , tested for leaks and turned the breaker for the disposal back on and everything worked perfectly

TESTED SYSTEM NOT COOLING FOR WHOLE HOME. UNIT FROZEN DUE TO FAILED DAMPER MOTOR. TESTED ALL COMPONENTS POSSIBLE & FOUND FAILING CAPACITORS, DIRTY COND COIL, DIRTY BLOWER WHEEL, SUBPAR FLOOD PROTECTIONS, & WEIGHTED BYPASS DAMPER. Today I completed repairs, including replacing the damper motor, replacing the blower capacitor, dual capacitor, adding wet switch, SS one, Cleaning, condenser coil, Replacing 1 inch filter, and Bluetube uv light to unit. After completing repairs the system was thawed out and I tested refrigerant levels. Found the unit low on refrigerant by about two and today. I also charged it up. No immediate failures at this time.
I’ve been a customer of TEC for many years, and as usual, they were prompt & efficient in repairing a surge-damaged light switch that caused my kitchen to go dark. Adrian & his helper were a delight to have in my home & quickly found the problem, explained what caused the damage & replaced all my can bulbs for me. I use TEC for all my electrical, plumbing & HVAC service. They are the best!

Troubleshot and made repairs to flood light not working.
Excellent

We will replace the GFCI outlet in the garage with a regular duplex outlet and GFCI protect it from the panel

Replace the bad switch with a dimmer

Customer has disposal that is malfunctioning due to rust/age. Manually I jammed disposal with key. Left estimates for future replacement.

Install new 50 gallon gas fired water heater. All work was tested and documented with pictures.

Performed 1 system diagnostic for upstairs unit. Found compressor intermittently turning on,. Found failed dual run capacitor, compressor drawing high amps, dirty condenser coil. Connected gauges and tested unit with new capacitor. Found unit short cycling from a restriction in the line set.due to age of unit and unit being out of warranty. Recommended replacing coil and condenser. We replace upstairs furnace 2 years ago. Also gave estimates for repairs and coil/compressor replacement with new refrigerant. Based on our findings today, it might be time to think about getting a brand new system.

Upon arrival customer stated that system was cooling properly. This is a 2 zone system. Unit is 4 years old. After inspection of system found that unit had a failed outdoor capacitor. Contactor tested good, condenser coils are clean, drain line is clean. Blower wheel is clean. Spoke with landlord about today’s issue, she approved to have capacitor replaced today. Replaced capacitor and tested amps on condenser fan motor, and compressor, everything tested out great with no issues. Refrigerant levels tested good with no issues at this time. Unit back up and cooling.

Arrived to find blower motor and control board had burned up. Blower would trip breaker and burning smell coming from control board and blower motor. Replaced and system had 18 degree delta. Will schedule homecare at a later date.

For this job I cleaned 2 blower wheels, a condenser, and installed a wet switch and ss1 for both systems . After completing the job I tested both systems to ensure everything was working as well as verified the pressures and temperature . The customer mentioned that both of the kids rooms upstairs gets hot and I recommended added 2 return ducts to those rooms. Another option was upgrading the thermostat and adding 2 sensors in each room . Either of these Tstats would work with sensors . Honey well t9 or t10

For this job customers upstairs bedroom had lost power. Customer stated bathroom switch was turned on and a loud pop happened. After inspection the back stabbed switch had broken. We also found a loose neutral wire for that circuit in the main panel causing the power to be sporadic to the room. We replaced the switch with a new single pole switch and made a new connection in the main panel for the neutral wire. We also did a load calculation in the customers home and it came out to 154 amps out of 200.

Came back on April 25, 2025 and properly replaced the upstairs system evaporation coil. Pressurized system. Performed a deep vacuum up to 600 µm. Recharge the system with 8lbs of R-410A refrigerant. System is cooling properly at this time with 20° delta split. Additionally, clean both upstairs and main floor condenser coils.
Knowledgeable and very nice to work with! Highly recommended!

Customer called us back out again after having septic tank flushed. Tested all fixtures and found no evidence of a blockage at this time. Customer has a bathroom sink drain line that is broken and leaking into crawl space. Camera inspection scheduled for today 2-5 to provide estimates for repair and also perform camera inspection as a courtesy.

Just this weekend out A/C went out in one of our rooms. As fate would have it as we talked in the car about getting a repair technician out to investigate, we turned into the neighborhood and Ellot was working on the next-door neighbors unit. I asked if he could take a look at our situation. He checked in with dispatch and was over in about 15 minutes. After a thorough inspection it was determined we had a couple of defective parts. A quick replacement with what was on the truck and we were good to go. Priced fair for not having to wait for parts. I would highly recommend them in the future.
Excellent service!
Mike showed up promptly. Knew how to remedy the problem immediately. Had the part on the truck and fixed it quickly.
I just wanted to say that Myles came out, assessed the issue and was able to promptly provide a solution to get me back up and running in very little time. I have hot water again and am very pleased with the TE Certified team.
Professional, knowledgeable
Could not be happier with the Servicemen today from TE. Elijah & his assistant were very knowledgeable, accommodating & they were very friendly & respectful of our home. It was a pleasure to see them again & have them working here. Great job!! Thank you !
Cory and Navy were great. I would definitely request them again!
Outstanding work! Very much appreciated.
Have had a recurring leak issue in a garden tub over last 7 years: Austin is the 4th plumber to look at this: Unlike the other 3 plumbers before him he listened to what I was telling him, that I needed something other than a quick fix. He offered a solution to fix it permanently . My wife and I are very happy with the work he did and that this nagging issue is now fixed.
