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 the customer had a leak coming from the guest vanity showing itself in the living room ceiling. Further inspection showed a pin hole leak on the copper. The customer decided to do the repair as well as a partial repipe of the basement. Water was shut off to the home and the old copper was removed and replaced with pex. All work was thoroughly tested for leaks and proper function. The area was cleaned to the customers liking.
On today’s visit we performed a troubleshoot for tripping breakers. All breakers tripping are QO Dual Function breakers. The issue started about a month ago and many of their neighbors report having the same issue. Cobb EMC has been out to look at the transformer but claim it is not on their end. I was unable to replicate the tripping. The homeowners agreed to replace one of the affected breakers as a test case to see if it holds with a new breaker.
We replaced all of the smoke detectors in the house.
Repiped house with pex water lines. Insulated hot, recirc line and in the garage. Added stud guards and fire sealed. Installed new pit filler and kitchen faucet. Adapted onto shower valves. Secured pipe and tested.
Split Job. Service Upgrade, Smart Panel, Whole Home Re Device, Server Quad Outlet, Furnace Accessory Quad, Fireplace Outlet, Garage Lights, Upstairs light, Upstairs Fan. Will return next week Monday/ Tuesday to complete remainder of work.
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.
Completed a full spring maintenance on one HVAC system. Inspected heat exchangers, burners, and ignition components for safe operation. Checked blower assembly, airflow, system settings, electrical connections, breaker sizing, and motor amp draws to verify proper performance. Tested controls and safety switches and inspected for any potential safety or code concerns. System is currently operating as designed at this time. Gas pressure was adjusted to manufacture specs. Blower wheel is getting dirty and system lacks any time of indoor air quality device. Untreated, indoor air allows, allergens, bacteria, and odors to continuously recirculate through the home and HVAC system, contributing to poor air, quality and internal system contamination. The APCO-X Purification system is recommended to neutralize these contaminants at the source and prevent ongoing buildup . Without air purification, airborne pollutants, such as allergens, bacteria, and odors remain present in the HVAC system, and
Technician installed a new water service line from the meter to the home. The new line enters on the left side of the home, runs up the wall, and then drops down to tie into the existing main. All penetrations were sealed with hydraulic cement and tar. The home had been repiped with PEX before the current homeowner moved in. Original water lines in the slab and walls were left in place, with uncapped piping concealed inside the wall. The leak originated at the original water main where it rises into the water heater room. Water followed the route of the old piping into the walls and flooded the first floor. The homeowner was unaware that the original piping remained in the slab. Technician also replaced the toilet in the upstairs bathroom above the garage and installed new toilet bolts, a wax ring, and a supply line. The base was sealed with a hygienic seal. The toilet was tested for proper operation, and no leaks were observed at the time of testing. Capping the remaining water lin
Arrived to troubleshoot the furnace circuit after the breaker had tripped. Upon inspection, found that the furnace and garbage disposal were sharing the same circuit. Recommended separating the loads and relocating the furnace, garbage disposal, and an additional kitchen lighting circuit to a new subpanel. Relocated the oven circuit wiring to the subpanel, freeing up two spaces in the existing panel for the additional circuits. Installed dual-function AFCI/GFCI safety breakers to provide the required circuit protection. Also inspected the garbage disposal receptacle and found the hot and neutral wires reversed. Corrected the wiring and tested the receptacle for proper polarity. Tested the completed work and verified proper operation.
Rewire Splice
Home care completed on two systems. Media filters replaced with approval. Drain lines flushed. Noticed ductwork on both systems to be undersized. Advised homeowners and the decision was made to not discuss any further at this time. Both systems operational upon departure. Thank you for choosing TE certified!
Upon arrival, met with customer and spoke with them regarding their issue. Customer stated that their kitchen sink drain has been slowly getting worse over time and now it is not draining at all. Both sides of the sink are holding water. The dishwasher has been draining properly. There is a clog in the tubular underneath the sink. I removed the p trap and it was clogged with rice/oats. I cleaned all of the tubular piping under the sink and reconnected them. Tested sink and it is now draining well. No leaks. Cleaned work area. Thank you for choosing TE Certified.

We will install new outlets for tv’s in the home and replace the existing surge protector with a higher rated one.
Garage circuit was extended to new outdoor outlet. Conduit was installed down the wall to accommodate new wiring, an outdoor rated box and outlet was installed. Outdoor box was seal with silicone to ensure moisture/water stays out. We tested everything and it is all working as it should.
On today’s visit, we installed a new outlet for a bidet. We came out of the vanity outlet to a J box outside, down along the exterior wall with pvc, to a second j box and into our new outlet. We also installed a dual function breaker on the circuit to provide both arc fault and ground fault protection.
Arrived on site to flush customers tankless water heater. customer had requested we come out and service her tankless water heater because she has been getting inconsistent hot water, at the shower and noticed the kitchen sink. Fixtures would get hot then get cold. I informed her that only flushing the heater may not solve the issue and could be something else causing temp issues. I went ahead and replaced the internal check valves , and installed an external check valve on the dedicated Recirculation line as well as a ball valve . After parts were installed I went through the house and ran hot water at all the fixtures . I then went to the master shower and let the water run for 20 minutes and found no reduction in temperature .
Today we came out for the main level not heating 2014 Lennox single stage 45k furnace found failed draft inducer motor. Client would only like to get repairs made at this time. Installed new draft inducer assembly checked operations and left equipment operational
Returned to the home to wait for the inspector to arrive and went over the project with him and opened light locations he requested so that we can get the rough and final for the original electrical work permit and the final for the service upgrade.
Came across no power to Tstat. Went down to the garage and found the furnace not have any high voltage. Checked breakers, everything was on. Found a Light switch around the corner that powered the switch for the furnace. Flipped that on and everything came on. System was heating great, indoor temperature was too cold to trigger the AC. system is operating upon departure.
