About this service
High-Efficiency Water Heater Replacement in Carrollton
High-Efficiency Water Heater Replacement in Carrollton means swapping a failing tank or aging unit for a condensing, power-vent, or heat-pump model that squeezes more heat out of every therm of gas or kilowatt of power. We cut the old unit loose with a tube cutter, drain it with a water heater drain pump, and rebuild the connection with copper pipe or PEX tubing, brass fittings, and dielectric unions so electrolysis never eats your new tank. Every install gets a new expansion tank, T&P valve tester check, and a fresh anode rod.
Carrollton sits in Carroll County where the water runs hard enough to shorten tank life, and many homes still have the builder-grade 40-gallon unit from the 1990s. If you are searching for high-efficiency water heater replacement near me and your basement floor is wet, we can usually get a truck out the same day. We also handle the permit and inspection so your install passes Uniform Plumbing Code and NFPA 54 on the first visit.

What's included
What Our High-Efficiency Replacement Covers
Every high-efficiency water heater replacement we do in Carrollton includes the parts and labor below. If your setup needs a gas line upgrade, a new vent run, or an electrical circuit, we price that separately and tell you before we start.
Code-Correct Connections
Copper pipe or PEX, brass fittings, dielectric unions, and Teflon tape on every threaded joint. We test the gas connection to NFPA 54 and confirm the venting meets the International Plumbing Code.
Expansion Tank and T&P Valve
A new expansion tank goes on the cold side and we test the temperature and pressure relief valve before we open the supply. These two parts prevent the pressure spikes that kill tanks early.
Permit and Inspection
We pull the Carrollton permit and meet the inspector on site. You get a documented, legal install that will not raise questions when you sell the house.
Removal and Haul-Away
We drain the old tank with a pump, disconnect it, and carry it out. Nothing sits on your curb, and the old unit goes to proper disposal.
Warranty Registration
We register the manufacturer warranty in your name and hand you the paperwork. Our workmanship carries a 6-year labor warranty on top of whatever the factory covers.
How it works
What to Expect on Install Day
We ask how many people live in the house, how many bathrooms, and whether you have gas or electric. That tells us whether a 50-gallon tank, a 75-gallon, or a Navien tankless fits your demand. You get a flat price before we roll.
We kill the gas valve or breaker, close the supply, and hook up a water heater drain pump. Draining a 50-gallon tank takes about 15 minutes. We lay drop cloths and move anything within four feet of the unit.
The old tank comes out through the same path it came in. We disconnect the gas flex connector, cut the copper with a tube cutter, and carry the unit to the truck. Removal and disposal are included, so nothing sits on your curb.
We set the new unit, level it, and rebuild the connections with copper pipe or PEX, brass fittings, dielectric unions, and Teflon tape. A new expansion tank goes on the cold side, and we check the T&P valve with a tester before we open the supply.
We fire the burner or energize the element, watch the flue for proper draft, and confirm the thermostat holds at 120 degrees. Then we walk you through the shutoff, the anode rod schedule, and what the warranty covers.

Tools & methods
Tools and Methods We Use
Water heater drain pump
Empties a 50-gallon tank in about 15 minutes instead of an hour of gravity draining, which keeps the job on schedule and the floor dry.
Tube cutter and soldering torch
Cuts copper cleanly and makes leak-free sweat joints. We use them on every copper connection and pressure-test before we open the supply.
Multimeter and T&P valve tester
Confirms heating element continuity and verifies the temperature and pressure relief valve opens at the rated setting. Both checks happen before we call the job done.
Pipe wrench and flaring tool
Tightens gas and water connections and forms flare fittings on gas lines where code calls for them instead of a soldered joint.
Dielectric unions and flexible connectors
Separate copper from steel to stop electrolysis, and absorb vibration so the connections do not crack over years of thermal cycling.
Expansion tank
Absorbs the pressure created when water heats and expands, protecting the tank, the T&P valve, and every fitting in the system.
Real results
Before and after.
High-Efficiency Water Heater Replacement
Leaking 40-Gallon Swap in Trinity Mills
A 13-year-old 40-gallon tank was weeping from the shell onto a basement floor. The anode rod was gone, sediment filled the bottom third, and the T&P valve was stuck shut.
After: We installed a high-efficiency 50-gallon unit with a new expansion tank, dielectric unions, and a fresh anode rod. Recovery time dropped from 55 minutes to 38, and the floor stayed dry.

High-Efficiency Water Heater Replacement
Tankless Conversion in Castle Hills
A family of six was running out of hot water every morning with a 50-gallon tank. Their gas bill averaged $95 a month, and the unit was 11 years old.
After: We converted to a Rinnai condensing tankless unit, upgraded the gas line, and ran a new side-wall vent. Their first full month's gas bill came in at $71, and hot water never runs out.

Emergency Holiday Replacement in Downtown Carrollton
A tank ruptured on a Saturday morning before a family gathering. Water was spreading toward stored boxes, and the pilot would not stay lit even after relighting.
After: We shut the supply, pumped the tank dry, and had a high-efficiency 50-gallon unit installed by early afternoon. The family had hot water for the evening, and the old tank left on our truck.

Problems a High-Efficiency Replacement Solves
Most calls we get in Carrollton start with one of these four symptoms. Each one points to a tank that is past saving, and each one gets fixed the same day we install the new unit.
Ask a pro →Leaking tank flooding the closet floor
We shut the supply, drain the tank with a pump, and install a high-efficiency replacement the same day. The old unit leaves on our truck, and we dry the area before we set the new one down.
Rusty water and popping noises
We replace the unit with a high-efficiency model and install a fresh anode rod. On tankless conversions we flush the heat exchanger and set the thermostat to 120 degrees to slow future scale.
No hot water after a pilot light outage
We diagnose with a multimeter, price the repair honestly, and replace the unit when repair no longer makes sense. Most Carrollton swaps finish in three to five hours, so you have hot water by dinner.
Gas smell near the water heater
We shut the gas at the valve, test every joint, and replace the connector and fittings during the install. Every gas connection gets checked to NFPA 54 before we relight the burner.

What Replacement Costs in Carrollton
$1,450 - $3,200 installed, depending on unit type, venting, and gas line work
Typical 2026 pricing for high-efficiency water heater replacement in Carrollton runs $1,450 to $3,200 installed. A standard 50-gallon gas tank sits near the low end. Tankless and hybrid heat-pump installs land higher because they often need a new vent run, a gas line upgrade, or a dedicated electrical circuit. The quote you get includes the permit, the expansion tank, and haul-away, so the number you hear is the number you pay. We will tell you plainly if a standard unit fits your budget better than a high-efficiency model.
A high-efficiency unit costs more up front and cuts water heating energy 20 to 35 percent. Over a four-year stay, most Carrollton homeowners come out ahead, and they get a longer warranty and fewer emergency calls along the way.
•affects cost
A 40-gallon unit costs less than a 75-gallon, and a tankless or hybrid heat-pump unit costs more than either. The right size depends on how many people live in the house and how many fixtures run at once.

Gas installs need a properly sized line and a tested flex connector. If the existing line is undersized for a high-efficiency unit, upgrading it adds labor and material to the job.

A straight atmospheric vent is simple. Power-vent and condensing units often need a new side-wall termination or a larger flue, which adds a few hundred dollars and a couple of hours.

What Carrollton Neighbors Say
★★★★★
“Our 14-year-old tank started weeping on a Friday afternoon. They had a 50-gallon high-efficiency unit in by 4 p.m. the same day. The tech showed me the old anode rod, which was down to nothing, and explained why the new one matters. Clean work, no mess left behind.”

“We switched to a Navien tankless and the crew handled the venting and the gas line upgrade without drama. They pulled the permit and met the inspector. Our gas bill dropped about 22 percent the first full month. Worth every dollar.”

“I manage four rentals and needed a replacement done between tenants. They installed a high-efficiency 40-gallon unit, replaced the expansion tank, and sent me the paperwork the same day. No callbacks, no leaks, and the tenant moved in on schedule.”

We do. Our technicians hold a Georgia Plumbing License and manufacturer certification for Rheem, A. O. Smith, and Navien equipment, and we work across Carroll County daily. We pull the permit, meet the inspector, and test the gas connection to NFPA 54 before we leave. Call (943) 469-0029 and we will size the unit over the phone.
A straight tank swap takes three to five hours. If we are converting to tankless or a hybrid heat-pump unit, plan on six to eight hours because the venting, condensate line, and electrical circuit usually need work. We give you a realistic window when we book, not a two-hour promise we cannot keep.
Yes, if you plan to stay in the house more than four years. A condensing or heat-pump unit cuts water heating energy 20 to 35 percent, and Carrollton's hard water shortens the life of cheap tanks anyway. You get a longer warranty, lower bills, and fewer emergency calls. We will tell you honestly if a standard unit fits your budget better.
