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

Replaced leaking water heater. Repiped as needed. Tested for leaks and function, all good. Thank you for choosing T.E. Certified.
JR is personable and professional along with being a great technician. We are very pleased with his work.
Brandon was very professional and friendly.

Customer had a toilet leaking from the base. I left options to replace or just pull and reset. They opted for replacement. After getting signatures I went and purchased a new toilet. Upon pulling the old toilet I noticed two things. Flange was too low, and water was holding inside the drain. I went into the crawlspace to inspect the plumbing. The line for the toilet was extremely back pitched. Due to the previous drain install for the master bathroom, the only solution is to repipe the drain line for the master bath room. Left estimates for that work. When I went to turn water back on to the home I noticed a wet spot in the yard. I let customer know about service leak and that the main valve and prv were in really back condition. Presented the option to fix and customer agreed. I will be sending estimates for a whole home water repipe and a new water service.

Troubleshooting car charger outlet not working

Customer called us out for multiple drains that were stopped up or draining slowly. The master bathroom upstairs was draining slowly whenever the shower was being operated. The toilet was also gurgling. I performed a thorough investigation to make sure this was not a main drain stoppage and it was not. I augered the toilet in the master bathroom and was successfully able to remove stoppage. I flushed several times and ran water to ensure everything was draining properly. I did snake the shower drain and also was successful at removing the stoppage. Shower is draining properly at this time. The customer just moved into this home two weeks ago and as a courtesy I also checked the upstairs left bathroom and made sure to auger the toilet, ensuring this toilet was also draining and flushing properly. Customer is very satisfied.

Full system

We came out today due to the A/C not working and at the thermostat it was reading “No power”. The customer agreed to the diagnostic and this is what was was found: -A/C Disconnect- Circuit # Unit had 240v line to line and 120v line to ground. But we noticed some issues inside and they are as followed: *The existing disconnect has rust on terminals *Enclosures bonding is corroded *Cable is missing a proper connector *Dust and debris inside. Although the was getting power the disconnect was in a bad shape and needed to be replaced which we supplied and installed a new 60 amp non fused disconnect. -Furnace Switching- Circuit # I noticed someone had removed the disconnecting switch for the furnace and made a very poor splice of the wires. After removing the wire nut you could see where only (2) wires were connecting along with the insulation melting due to heat. I tapped the wires together to see if the unit would come back on and it did. We completed the follow work below to correct

Repiped pool house due to copper freezing. Tested for leaks and cleaned up.

Removed existing 3 inch exhaust and fresh air piping for tankless water heater located in the garage. Original piping was not installed properly and was causing condensation to drip onto the exterior of the home. Technician hung new 2 inch PVC, fresh air and exhaust piping in the garage and ensured proper slope. A new electronic display was also sent directly from the manufacturer, as the old was not functioning properly. New display was successfully installed. Parameters were set back to their original settings on the Navien tankless water heater. All air was bled from the plumbing system to ensure proper tankless functionality. All work performed was tested for leaks and proper functionality. Work area was thoroughly cleaned up and payment was collected. THANK YOU for trusting T.E. Certified!!

Ask for Kurt, a very efficient, capable technician that took care of a variety of issues we had. I appreciated the same day service since we have a tight schedule! Highly recommended--very knowledgeable and delivered as promised!
Great service.
Jeffrey Phung did a great job. He is very professional and knowledgeable.
Joaquin was outstanding. He is a true professional.
Excellent service
The service looked to be a quality service. I have no doubt most of the items identified that need attention are pretty accurate. I do think your pricing to correct or update is too high on certain items. Cleaning the coils on the outside units being one of them.
The technician was very knowledgeable and helpful, answering many of my questions, explaining exactly how the job was going to be done.
I had a very non-standard and difficult task. James did a great job of problem solving and keeping me informed. Would recommend.
Super informative, quick and all around nice guy!
Excellent Service
