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 PRV and set house pressure to 65 PSI. Flushed out both electric water heaters. THANK YOU for being a valued HomeCare member, and for trusting T.E. Certified!
Liam was amazing. He installed an EV charger very quick and efficiently
Ali, thank you for the 5-star review and kind words. We are glad to hear Liam installed your EV charger quickly and efficiently. We appreciate you taking the time to share your experience with TE Certified.
Two full system replacements. New plenums. Duct modifications. New thermostats.
I came out to investigate an issue with the dishwasher, not working as well as a smoke detector that wasn’t working. I investigated the issue with the dishwasher and found that your breaker was tripped off. For the smoke detector this was a bad smoke detector and I replaced it with a new smoke/carbon monoxide detector. Because the troubleshoot was very simple, I did not charge you for the troubleshoot, but did that as a courtesy. Thank you for using TE certified electrical! Veaya
On today’s visit we came out to replace 2 exterior lights on the front porch. One of the lights was broken in the packaging, and the homeowner is ordering a replacement. We will need to come back at a later date to install the replacement when it arrives.
Tesla Wall Connector Installation
I came out to investigate an issue with the recessed light as well as to give prices for landscape lighting. The recessed light had a very small issue. The tab up inside the socket was pushed down flat so that it was not making a good connection with the lightbulb. I was able to fix that and the light is working great. While we were looking at your landscape lights, we noticed you did not have it out front porch outlet so I went ahead and installed that for now and you can get back to me when you’re ready to do your landscape lights. Thank you for using TE certified electrical! Veaya
Outstanding service! Very personable and knowledgable.
On today’s visit I met with the homeowner. The homeowner expressed a issue with a clogged sink and non operational garbage disposal. I took a look and was able to brake it loose with a disposal key. The sink and disposal are back to functioning properly. Thanks for choosing TE certified plumbing!
Run cable through floor drain Ran k400 through floor drain on backside of building. Ran cable until we cleared blockage and water from all floor drains cleared. After clearing we ran water for a long duration of time. No signs of system backing up. Clearing successful. Thank you for choosing TE Certified.
Replace costumer supply lights
We completed a full panel restoration, install a whole home, surge protector, and run a new circuit for outlets in the basement.
Installed Tesla wall connect and whole home surge protection at panel .
Full system installed for Basement with: New safety switches New smart thermostat New drain line New whip and disconnect New return plenum New drain pan New condensate pump New media AprilAire cleaner
I was called out to Byrd’s house for a homecare maintenance. We recently installed the system so we performed a thorough evaluation. During the evaluation we changed the filter, set up the WiFi for the thermostat & adjusted the settings, adjusted the gas pressure, and cleaned the drain line. The system can benefit from additional air quality and the ductwork up in the attic is very outdated.
New water heater installed. While installing, found pinhole leake in non related pipe and fixed.
Replaced aged AO Smith water heater with new AO Smith 10 year warranty water heater. Tested for leaks and function no issues. Repaired pinhole leak. Tested for leaks and function. No issues. Bubble tested all new gas connections and found no leaks. Bubble tested a second time approximately 30 mins later and found no leaks.
We performed an electrical home, care inspection, and replaced the light in the basement
Jeffrey was my technician today and he was absolutely incredible! Super friendly and extremely knowledgeable. He explained everything happening with my electrical panel very simply so I could understand it and my options. He also spent time figuring out the issue with one of my light switches before fixing it. I would definitely have Jeffrey do electrical work at my house again.
Performed panel restoration and installed surge protection
For this job
Came out today to locate the pressure reducing valve. Valve could not be located. Pressure was reading 130. Dug up area downstream of meter and installed shut off valve and watts 25aub pressure reducing valve. Set regulator to 65 psi. Installed regulator and valve in access boxes. Restored water to home. No leaks were observed.
Arrived on site to look at a chirping smoke detector in the master bedroom. The homeowner stated that this smoke detector started chirping on 10/24. The batteries in these smoke detectors haven’t been replaced since installed in 02/24. I recommended replacing all batteries since they need to be replaced annually. For today, we replaced the bedroom smoke detector battery. We tested all smoke detectors and they are working as they should. Everything is working upon departure.
Ricky is the BOMB - genuine human who is great at his job. Calling him for everything.
Thank you, Chelsea, for the fantastic 5-star review. We’re thrilled to hear Ricky made such a great impression, and we’ll be sure to share your praise with him and our team. We appreciate your kind words and support of TE Certified.
Homeowners called us out to assess sewer smell coming from the half bathroom. I pull the wobbly toilet to inspect the flange. The flange had spacers installed at the incorrect height. That coupled with the wax ring never being able to make a full seal caused the smell. I raised the flange to the appropriate level, reset the toilet and tested for leaks.
For this job, I conducted lead detection services as a TTL for original technician JR. During the investigation, I did introduce compressed air to the system via the unregulated hose bib on the right side of the home. I discovered the leak in the middle of the yard halfway between the driveway and the tree in the front yard Approximately 8 feet off of the retaining wall in front of the front porch. Location has been marked with blue flags.
Dug up yard due to a large wet spot near the meter. Customer had a handyman do a repair last week but there is still water. Found repair but no leak at the repair. Set up leak detection for customer. Customer elected to leave hole open at this time.
For this job, the customer had a small leak on the pressure relief line on the heater, and issues that I noticed with the venting of the old heater. After diagnosis and going over options with the customer, he decided to go with option one to replace the unit with a short 50 gallon gas to accommodate the pitch of the vent, and replacing the PRV and doing a minor leak repair on copper in the basement. Once complete we tested our work and cleaned up. Thank you for choosing TE Certified.
Dig up are in front yard to locate water main break that leak detection has marked. Repair water main and back fill area, replaced main shut off valve
We installed a new 200amp, whole home electrical service upgrade in order to fix the burnt main panel and also addressed the electrical for the open permit involving the living room expansion. We installed a new main electrical panel, new service wire, a new 200a meter base with safety disconnect outside, an updated the grounding system, new safety breakers and smoke and carbon monoxide detectors per current code and whole home surge protection for the main panel.
Very happy customer! TE always has the best technicians and Caleb was the perfect example of thatfriendly, knowledgeable and wanted to make sure the job was done right!

Vincent was great. Very helpful and did awesome work
Gabe was great as always! He is very particular and careful with his work, we really appreciate his attention to detail and listening/customer service mindset.
James did the right thing. It's not the easiest thing to do, but he stayed all day and did the right thing to rewire electrical outlets so a fire didn't break out behind my kitchen walls one day.
Lá-Shaun, thank you for the thoughtful review and kind words about James. Your safety is our top priority, and we’re glad he took the time to rewire the outlets the right way. We appreciate you sharing your experience and trusting TE Certified with your home. I’ll make sure James and our team see your feedback.
Vinny was fantastic. He is very knowledgeable and thorough. He went over and beyond any service rep I have dealt with. I highly recommend him!
This was my first experience with TE Certified, it won’t be my last! Vinny was extremely knowledgeable. He explained everything in detail and completed my job exactly like he said. I couldn’t be more pleased! Great service, very knowledgeable, respectful and friendly!
Dylan was kind, patient and respectful. He explained everything he was going to do and reviewed all the issues completely. To bring all, or at least my major plumbing issues up to par, I felt Dylan gave me a very fair price. I have never been disappointed by a TE Certified employee and I’ve now used HVAC, electrical and plumbing. Thank you for everything, Dylan!!
Toilet repaired
Great service
Great Service
We had an emergency situation with our water heater this morning I called Chris at TE certified and he was knowledgeable and addressed my concerns. Scheduled the technician Ricky to the technician that afternoon to diagnose the problem. I was informed every step of the way with the progress and ETA of the tech. Ricky was on time, professional and well presented. He was able to find the problem and got the necessary parts and got the water heater working correctly. Very grateful to the team and I will use their HVAC company to service my home. Very satisfied with the service and well recommended Thank youp
Cody was very personable, listened and understood my concerns. He was efficient and paid attention to detail, and arrived at the anticipated time.
Kevin listened to what we wanted and did a great job!!
This is our 2nd time using TE and Joaquin Partida. I am SO GLAD that we found Joaquin. He has done excellent work with various installations and always cleans up after himself. He is prompt, efficient, pricing is very fair, and he's polite & personable. He is definitely our go-to guy for electrical needs. If you need an electrician I highly recommend Joaquin Partida!
We had a water mark on our basement ceiling which is under out Master Bath shower. Fernando cut a hole in the ceiling and checked pipes, it was not the pipes. He looked at the Shower and said it may just be calking and if not that it was probably the drain which couldn't be seen without pulling apart the shower floor. He suggested we recalk with 100% water proof calking and test it. If it still leaked it was more than likely the shower drainpipe. Lucky for us the calking did the trick. We were very happy with Fernando. What I didn't like is that he was only their to check to see where the leak was but if found, TE had to send someone else out to fix it. That part I did not like as I have in the past had plumbers come out diagnose the problem and fix it. I tried TE because I see their trucks in the neighborhood and nearby neighborhoods.
Excellent same day service
This is the second time we've had Joe work on our electrical in our home. He takes his time and explains what they will be doing before they start the job and then executes it with ease. Whenever we have electrical issues we always use TE and so glad we chose them.
Excellent service
ON TIME. CAPABLE. JOB WAS COMPLETED QUICKLY AND PROFESSIONALLY.
Excellent, as always.
Great Service
Eric was honest and thorough
Andrew was such a great technician, guided me through every situation that he was doing step-by-step of what he was going to fix
Called Saturday for a blocked laundry drain line and they had availability Monday morning. Kyle and his partner were prompt and provided excellent service. $500 to clear one blocked drain line (took 15 minutes) was way more than I was expecting to pay. They did great work but I’ll shop around next time.
