HVAC, Plumber & Electrical FAQs
The average cost to replace an electrical panel ranges from $1,595 - $3,000 depending on the amperage. The higher the amperage needed the more expensive the new electrical panel would be. Amp replacement is necessary when the existing system cannot be upgraded to meet new standard needs or when there is a safety risk to the existing system.
Tankless water heater cost in Marietta ranges from $1,500 to $5,000 depending on the size and type of the water heater being installed. Tankless water heaters have a higher initial price compared to tank heaters because of a more labor-intensive set-up if new gas and water lines are required for installation. For electrical tankless heaters, new electric wiring will probably not be needed for installation in most cases.
If you're experiencing AC not cooling your Marietta area home while the system is powered on, you could have a clogged or blocked coil. Unfortunately, a wide variety of debris can find its way into this equipment, including grass, dirt, and other contaminants. This can result in a serious clog, which can lead to a system malfunction. The best way to prevent this is with regular AC cleaning and maintenance visits.

Job Locations and Reviews
For this job, I replaced a panel with a burnt busbar
Trench new water main from water meter to home (outside only)
9/17: put ticket in w/ CEMC for 9/30, waiting for confirmation. MO Upgrade the home service to 200 A. Replace the existing electrical panel and add a new 100 amp outdoor panel sharing the same 200a as the main panel . Wire in a generator inlet on the main electrical panel. Add the required code safety items that Cobb County is enforcing. Wire some dedicated circuits and a dedicated 240 V circuit off of the new outdoor panel for outside electrical needs. Add two outside outlets on the front of the home. Run a dedicated circuit to a disconnect for the outside unit of the mini split.
Roughed-in and properly secured a new washer box in the mud room. Ran new water and drain lines for the system in the crawlspace. New vent piping was terminated through the roof above. Flushed tankless water heater. Also, replaced failed cold water shut off valve for the kitchen sink faucet as a courtesy to the customer. All work performed was thoroughly checked for leaks and proper functionality. Water was ran through the new drain line for several minutes to check all work completed. A walk-through was completed with the customer, all work areas were thoroughly cleaned up, and payment was successfully collected. THANK YOU for trusting T.E. Certified!
Homeowners tankless water heater was leaking from the recirculating pump in the unit. Unit is 11 years old and recommend replacing. The recirculating line is 1/2 pex that tees into the hot side near the kitchen and is not properly strapped. We will replace the recirculating line with 3/4 and strap. Need to replace the piping to the unit and install a new check valve and mini expansion tank. Run new venting for the intake. Condensate line goes into a pump and hvac also ties into the pump. Installed a ball valve on the recirc line to stop the leak and get the water back on. Noticed a leak from the drain in the basement from the washing machine. Pipe was not connected. Installed new pipe and mechanical fitting.
I replaced bulbs in the kitchen, batteries in the fan remotes and a switch in the living room and will return when the special material comes in.
No Cool - 2020 Goodman Customer explained that the situation with this system has been ongoing since installation. Unit never really cools the space. I checked refrigerant pressures and the system is low. TE added refrigerant in 2022. No record after that but customer did say another company added refrigerant last year. I leaked checked all accessible parts and found no leaks. Suspect the leak may be in the wall. The refrigerant line is ran in a wall that has been the chemical storage room for the pool supplies. It is possible the refrigerant line deteriorated and needs replaced repair. Cost for the leak search will be applied to the repair. Emailed estimates.
Installed new Tesla charger/ Load Management Kit + Installed Whole Home Surge Protection
For today’s service, I replaced a 4 foot section of copper piping that had pinhole leaks with a new section of copper on the vertical stack on the cold line. I also replaced two tub overflow, gaskets for the upstairs bathrooms. Turn the water back on and tested work and found no issues with what was done today. I’ve also provided an estimate to re-pipe the entire house with pecks piping and getting rid of all the copper piping. Estimate is valid for 60 days and after that timeframe they quote would need to be revised and may not be the same price as what was provided today in the estimate. Thank you for choosing TE certified and have a blessed day.
Came to troubleshoot the GFCI in the garage find out the connection are lose for GFCI installed by homeowner fixed and secured the connection and tested everything
For this job, I replaced existing smoke detectors
Concerns of system not coming on at all to cool. A quick visual determined that the condensate pump had shifted and was not fully settled, causing the pump to fill with water in the safety to shut the unit down. Adjusted the pump and it immediately began draining the water, which allowed the system to come on and begin cooling. Thank you for choosing TE certified!
Arrived on site to perform a 1 system Homecare for a 2021 Rheem AC/Furnace. We changed filters, cleaned drain lines and completed a comprehensive evaluation of the systems performance, condition, safety and cleanliness. We measured refrigerant, tested motors, tested airflow and ensured all combustion components were safe, clean and ready for heating season. We did discover the condenser coil extremely dirty, which clients approved having us deep clean today. I deep cleaned the condenser coil inside out, ensuring all paneling was secured as well. System is fully operational upon departure. Payment collected via credit card.
Removed the Gen 3 Tesla Charger in the garage and installed a junction box with cover plate to safely put the wires in and capped everything off.

We troubleshot lights flickering in the kitchen
For this call, homeowners was given options for repair or replacement of the main water service line and opted for the repair. We began by breaking up concrete where a leak detection company marked where the leak was at and found the pipe. We confirmed it was that by turning water back on for a moment. We cut out the section with the pinhole and put in new pipe in its place. We cut out the old gate valve to the home and put in a new ball valve as a courtesy as it had a leaking fitting in its area to give the homeowners a secure way to shut off water to the home without using the street meter. After completion, we tested everything for leaks and all is working as it should at this time. We put back the dirt and put in concrete for the garage. Thank you for trusting TE Certified with all your plumbing needs.

James found out why our electricity was not working in our Sunroom in no time. He reset our GFI and explained why we should replace the switches and receptacles in the Sunroom
Great work...very professional (& courteous too!)
Great service
I’ve use TE a few times in the last year-this was more involved but in each case they were on time and did a good job. Thank you
We were told on Tuesday by James that we had a leak somewhere in the slab. Michael, the leak inspector was sent out in a very timely manner the next day and after a lot of detective work found the leak in a location that was very accessible. Michael was professional and explained all the possible options available to us, and we were very satisfied with him, his service, and the outcome. James contacted us today and he will be here tomorrow to start the leak repair. We have been very satisfied with TE certified throughout the entire process.
This was the first time I called TE Certified to look at our upstairs air conditioning system. Frankly I expected the worst experience because of previous companies we used in the past. What a pleasant surprise. Great service, great and honest discussions, great recommendations and a pleasure to work with. Shane’s expertise, knowledge and resolution save the day. Restored our system and set up a schedule to discover problems before they happen. Glad we called them, looking forward to working together in the future.
Excellent service
Upselling rip-off artists. Came to one of my homes to check a couple of things. before I know it, the guy has the electrical panel off (I didn't ask), and they are sending me estimates for thousands of dollars. (which I decline) After many emails, we got an estimate for what I actually need. When the guy shows up he says it will be 50%, more for x,y,z. I always need electricians, but I won't work with TE again.
He really knows what he speakes of and I was impressed
Wayne was patient, very knowledgeable, and courteous. He analyzed my issue, discovered the problem, and fixed it right away. He took time to explain additional items that may need attention. However, $200 hourly rate with no materials involved seems a little excessive. I plan to follow thru with the full panel replacement he recommends. However, I will seek additional bids. That said, I like TE Certified a lot, especially their experience and professionalism.
Bryan came right on time for the appointment and was an excellent technician. He had a great way of telling me what he was going to do and carefully explained his process. He also checked other elements during his visit. He and his teammate (David) were great to work with and I highly recommend Bryan and this company. Bryan is a great representative for his company.
This was our first experience using TE Certified & we were very impressed. Kevin is an extremely knowledgeable electrician, personable and professional. He was able to address and fix our concerns as well as complete some other electrical work. We will definitely reach out to them for future needs.
