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
Very personable and excellent work
Customer called us out for both sinks in the kitchen clogging. On arrival I tested the line and it quickly backed up. I gave the customer multiple options and they chose to have the line jetted and a bottle of Endure. I removed the trap and ran my jetter down the line clearing the blockage. I then ran the jetter down two more times to make sure it was clear. I then tested the sink throughly and cleaned up.
Home inspection
Hang lights and replace customer switches
Installed free standing tub and tub filler. We rested the tub on two 2x4 pieces of wood to test the drain for leaks before fully setting it to the floor. We leveled the feet of the tub to prevent rocking. The tub filler is mounted to the matching rough in block under the floor. We tested the filler for leaks, proper flow, and temperature adjustment. Thank you for choosing TE Certified! This bathroom turned out AMAZING!
Replaced a GE 60a breaker for a Tesla wall connector
Replace kitchen faucet, and replace water stop valve under kitchen
On this job customer had a small leak in ceiling with customer approval I cut the ceiling to find a small pin hole that form on a copper pipe. Again with customer approval I made all necessary repairs to fix the leak. Insloet legt estimate for whole house repipe since this isn’t the first time leak they had while living in the home. At this time there no other issues found that’s found thanks for choosing TE Certified.
Upon arrival, met with customer and spoke with them regarding their issue. Customer showed me upstairs to their master bathroom and stated that their freestanding tub is draining slowly. The tub is installed with a flexible drain hose. All other fixtures are draining properly at this time. I informed the customer that I do not recommend running a drain machine through the flexible hose as it may bind up the flexible piping or poke a hole through it. I informed them that I would likely only be able to plunge the tub to get it draining better and also recommended our Endure drain maintenance product. Gave customer options and after getting signature approval I began work. Ran hot water and plunged tub multiple times. Tub is now draining better. Still slightly slower than preferred but cannot be made better unless the flexible drain is replaced with hard pipe. Also applied first treatment of Endure. Cleaned work area. Whole house water pressure is at a safe level @50psi. Thank you for ch

Andrew was attentive and gave plenty of options for how to solve my issue. Would use again!
Thank you, Austin, for the 5-star review. We’re glad Andrew was attentive and offered clear options to resolve your issue. Your feedback means a lot to our team at TE Certified. We appreciate you taking the time to share your experience.
Today we’re called out because the homeowner had issues with their breaker tripping when an additional load was put on the circuit. He mentioned how frustrating it was to have the Wi-Fi go off for 10 to 15 minutes after the breaker with trip. He also mentioned wanting an ethernet run behind his TV into the utility room. Today we provided estimates on how to get his wants accomplished and installed a 20 amp circuit to the utility room to solve his frustration on the Wi-Fi. At the time of leaving everything is tested on working. Thank you for calling TE certified.
Very knowledgable and efficient
Troubleshoot lights not working.
On this job customer had a tankless that never had any maintenance. It still in a good age range so I gave customer some options. I recommend during a flush and installing a halo ion filter. So with customer approval I flush the tankless water and install a halo ion filter. Once installed I tested everything the water heater is working correctly and there no other issues found that’s for choosing TE Certified.
The feeders feeding the subpanel in the garage coming from the main panel inside the home has taken damage somewhere. The wire are leaving. The main panel is reading 251 V. When you go to the sub panel and test for voltage, you get 125 V on one leg and 0 V on the other. This is a quote to re-pull that circuit and have new feeders go to the subpanel.
2) System Inspection 2) 3 year old Goodman Systems Cycled each system through heat and cool from the thermostat. Checked both filters, filter in crawl space is a 14-25-1 and should be a 16-25-1. Took temperature readings at indoor equipment, inspected heat exchangers, blower motors, and coils. Checked and tightened all electrical connections, used multimeter to check all motors, power enhancers, and high wear components. Both systems are operating properly at this time with no immediate issues. No in-line flood protection on either system, highly recommend adding this to protect the home and equipment as well as a wet switch to the upper level system. Both systems are also a little short on return air. Both systems are heating and cooling properly and to their best ability at this time. Thank you for choosing T.E. Certified, have a great day!
Met with the owners on site and was shown to the master bathroom. The bathroom was remodeled two years ago with a new Toto AquaIV bidet. About a year ago, they noticed it was not flushing properly and was intermittent. Testing today, it appeared to be clogged. The flush valve and fill valve both appeared to function properly with the remote or manually but the bowl would fill. No other drains affected. I ran my auger through several times and found the toilet began flushing properly. I tested 10 times with and without paper. The toilet is functioning properly at this time. Perform draining clearing on toilet. Drain clear only. Does not include repairs or main line clearing. No warranty on drain clearing.
For this job, the customer is in the process of purchasing a new home. They called us out today to inspect the home’s electrical system. I completed a home buyers inspection and informed the customer of my findings.
Amazing service!
For today’s visit, we were called out here because of a pinhole leak on the hot side where it is located in the closet water heater. The pinhole leak was coming off of pecks piping that split. I replace the piping with new copper piping attached back to the pex pipe and removed the damage piping out. I also replace their pressure regulator with a new one of higher grade material that has a life expectancy of 20 years. I turned the water back on and tested the alliance for leaks and found no issues with the work that was performed today. I also advise that because of the amount of pinhole leaks that they’ve been having throughout the years approximately five times underground and in the walls that it’s probably time that the waterlines got replaced with new piping because of they’re on a collective billing through their HOA for their water bill and the building is off of one water meter that we would need to get the HOA involved to turn the water off and give notice to the neighbors tha
Wire customer supplied combo switch
Initial observations revealed the blower motor continuously running with no heat or cool functionality. Furnace board has a 6 block fault for open fuse revealing the fuse was tripped. Replaced 3 amp fuse and fault cleared allowing the operation of heat however, the flue pipe is completely rotted away and unsafe to operate as it is emitting carbon monoxide into the crawlspace and into the home through the return air system. The gas has been shut off to the furnace until this can be repaired. I also observed the return plenum is installed incorrectly and the filter is inside the furnace and unable to filter properly due to there not being proper clearance for the filter to slide in adequately. The return plenum needs to be replaced with an exterior filter rack. The furnace is not installed to code with gas flex inside the furnace. There is not proper clearance from the ground and no flood protection devices. Rodent dropping have covered the top of the furnace making it hazardous to brea
Install a water heater, safety shut off switch and a new light fixture.
No cool due to system being low on Freon and leaking at the evaporator coil. Also, outside condenser is dirty, blower wheel dirty, biological growth in the evaporator coil , filter was very dirty and heat exchanger is compromised and some heavy hot spots. Air quality in the house is compromised. System is 11 years old and not cooling. Two zones system . Sent estimates for potential repairs (nor recommend). At this age and conditions, the best option would be to upgrade system, and bring safety, savings and comfort back to the house. New system come with up to 12 years warranty and WiFi thermostat. We should credit back 98,00 spent today, if customer replace the system with us. Set a lead to quote upgrading for tomorrow after 2 pm.
For today’s service, I installed a grown post crossover T that did not have for one section of the house after a previous company installed a recirculating pump, but never installed a crossover T and just noticed now. I also did a minor toilet repair in the master bathroom that the toilet flushed tower ring had to disintegrated and needed to be replaced. Put everything back together and checked for leaks and found no issues with the work that was performed today. Work is complete and thank you for choosing TE certified and have a blessed day.

Kyle was my technician from TE and all I can say is that this guy was TOP TIER drain technician talent. He was as efficient and effective as you could possibly hope to have someone working on a main line blockage to be. To top it off, he was very try professional and enjoyable to interact with. Solely because of Kyle alone, I will continue to call TE first. Outstanding.

New water heater installed. While installing, found pinhole leake in non related pipe and fixed.
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.

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.
