Meh

Jonah did not seem confident in any communication. Was on the phone and checking the how-to manual. Other guy with him looked at the giant furnace and asked if it was a heat pump. They were pleasant and professional, but didn’t give “we’ve got this under control” vibes. Price for diagnostic was fine. Repair quote seems high.

Necessary repairs well done

Replacing a 50 year old electrical panel is not fun, but the job was completed with as few dings as possible. The work was well done, and the mess cleaned up.

Excellent electrical work

Chase, the electrical technician, was very professional and apprised me of several options to fix a complicated electrical configuration caused by a general contractor I had hired. He got everything up and running again, including a new fan and recessed lighting that had not been working. Highly recommend this company.

Very prompt and professional service!

Out of nowhere, a bathroom outlet started hissing and grinding. We got scared. I Googled “electrician Dunwoody” and started calling places. The first outfit I called said they could send someone- in three days! Next I called TE Certified. The answering agent said our outlet issue was urgent and she put us on the top of the list for same-day service. Within three hours, Jesus arrived. He called first, when he was a half-hour away. He arrived when he said he would and couldn’t have been nicer. He tested things and explained everything. He gave us options for fixes, and then he fixed us up. Very grateful to TE and Jesus, and the woman who answered my call!

Tested system not heating for the main level of the home. Found the blower motor, not kicking on due to a failed capacitor. Fully tested the system with a new capacitor and found carbon monoxide readings coming from the vents. Inspected the heat exchanger through the high limit and found a crack on the eyelet along with around the first bend of the heating exchanger. Based on our findings today, it might be time to think about getting a brand new system.

Tested system not heating for the whole home. This unit is a 90,000 BTU furnace with a 5 ton AC. Found the positive pressure switch was not opening and causing a fault on the board. Found that there was a good bit of water inside the drain and got all of it out. The system again was getting the same fault. Inspected the heat exchanger thoroughly and found multiple holes in the primary heat exchanger. Based on our findings today, it might be time to think about getting a brand new system.

Came out to master bath room, bar basement and partial kitchen remodel. Previous electrician clean up and restore power to basement bar area, microwave, kitchen switches, pre wired back deck heaters and rewired master bathroom. Surge protectors installed in both main panels. Most materials were customer supplied. No warranty given on previous work. If return visit is required that would require a charge.

The homeowner had a leaking garbage disposal, so I replaced it with a new one of the same size, featuring a one-horsepower motor. Additionally, I re-piped the main water line that enters the slab, replaced the main shut-off, the pressure regulator, and the hose bib shut-off for safety concerns and for homeowner to have higher water pressure. After completing these repairs, I insulated the pipes and thoroughly tested everything to check for leaks.

Called in for water pouring through ceiling. Homeowners turned off the water to the home. Upon arrival found that the ceiling was bowed, cracked, and holding water. Laid out plastic, and removed the drywall to determine what was burst. Found that a previous repair coupling had failed and burst causing the damage. Cut out the failed pipe and fittings and installed new pipe and fittings connecting back to the good, existing piping. Pressurized and checked the system.

Upstairs system is not heating due to a low voltage issue. I also noticed no ss1 on condensate drain, recommend wet switch to ensure no water issues, run capacitor is out of manufacture specs, gas sediment trap isn’t up to code, blower wheel is dirty, inducer motor is over amping, hot surface igniter is worn out, evaporator coil is rusted out, and system is low on return air by a 10 inch duct. Also noticed rust, burnt, and small hole on heat exchanger. Based on our findings today, it might be time to think about getting a brand new system.

Customer had a three eighths inch soft copper gas line that snapped off just below the shut off for the gas clothes dryer. There were two fixtures running off of the same three eighths line, which happened to be the dryer.And the range. They're dryer area within the utility room has an option for electrical.They opted to swap out their dryer for an electric dryer and simply cap off the line at the t for both fixtures. Capped off the line and tested with bubbles after turning the gas back on. I then tested the range for usability. It lit up on all burners. Thank you for choosing and considering t e for your plumbing needs
