About this service
What Navien Water Heater Replacement in Carrollton Involves
Navien Water Heater Replacement in Carrollton is the removal of an existing tank or tankless unit and the installation of a new Navien condensing water heater, including gas supply, venting, water connections, and startup. On a Navien NPE or NCB unit we check gas pressure with a manometer, cut and solder or press the copper pipe, set the T&P valve and expansion tank, and run a condensate line to code. The job usually takes three to five hours for a straight swap and six to eight hours when we are converting from a tank.
Most Carrollton calls come from one of three situations: a 12-year-old tank is leaking onto the garage floor, a family of five keeps running out of hot water, or a homeowner wants the lower gas bill that comes with a condensing Navien. We see hard water out of the Carroll County water system, so sediment buildup and a corroded anode rod are common on the units we pull. If you are searching for Navien water heater replacement near me, we cover every ZIP in town, including 30117 and 30116.

What's included
What Our Navien Replacement Includes
Every Navien replacement we do in Carrollton includes the unit, the labor, the code-correct connections, and the cleanup. If a gas line or vent needs work beyond a straight swap, we quote it before we start so there are no surprises on the invoice.
Gas and Water Connections
We run new copper pipe or PEX tubing with brass fittings, seal every joint with Teflon tape and pipe dope, and tie in a new gas flex connector. Gas pressure is tested with a manometer before we fire the unit.
Code-Correct Venting
The PVC vent is cut and glued to Navien's spec, with the correct clearance from windows and doors. Condensate is piped to a drain or neutralizer. We build to Uniform Plumbing Code and NFPA 54 so the inspection passes.
Old Unit Removal
We drain the old tank with a water heater drain pump, cut it loose, and haul it off. No tank sitting on your curb, no disposal fee tacked on later. That is part of the flat price.
Startup and Walkthrough
We purge the gas line, fire the Navien, and set the outlet temperature. You get a walkthrough of the display, the error codes, and the annual flush procedure so you know exactly how to keep it running.
How it works
Our Navien Replacement Process
You call (943) 469-0029 and we ask about fixture count, gas meter size, and venting path. That five-minute conversation tells us whether an NPE-180A, NPE-240A, or NCB combi unit fits your home. We quote a flat range before we roll a truck.
A licensed tech confirms gas line size, checks for a dedicated 120V circuit, and measures the vent run. We test incoming water pressure with a gauge and inspect the existing shutoff. If the gas line needs upsizing, we tell you before any work starts.
We kill the gas, drain the old unit with a water heater drain pump, and cut it loose with a tube cutter. The old tank goes on the truck for disposal. We cap the lines, then prep the wall with blocking rated for the Navien bracket.
We hang the Navien, run new copper pipe or PEX tubing with brass fittings, and seal every joint with Teflon tape and pipe dope. The PVC vent is cut and glued to the manufacturer's spec, and the condensate line is pitched to a drain. A gas flex connector ties into the shutoff.
We purge the gas line, fire the unit, and set the outlet temperature with a multimeter on the thermistor. You get a walkthrough of the display, the error codes, and the annual flush procedure. Total time on site is usually three to five hours.

Tools & methods
Tools and Methods We Use
Water heater drain pump
Empties a 50-gallon tank in minutes so we can cut it loose without flooding the floor. Faster and cleaner than a garden hose siphon.
Tube cutter and soldering torch
Cuts copper pipe square and makes clean soldered joints. We also carry a flaring tool and press fittings for tight utility closets where a torch is not safe.
Pipe wrench and flaring tool
Breaks loose old unions and makes flare connections on gas lines. We use a pipe wrench on the gas shutoff and a flaring tool where code calls for a flare.
Multimeter and T&P valve tester
Tests the thermistor, heating element, and thermostat on electric units, and confirms the T&P valve opens at the right pressure. We test before we call a job done.
Manometer and gas leak detector
Verifies gas pressure at the Navien inlet and sniffs every joint for leaks. NFPA 54 requires the pressure test, and we do it on every install.
Expansion tank and dielectric unions
Controls thermal expansion on a closed system and stops galvanic corrosion where copper meets steel. Both go on every Navien replacement we do.

Navien Water Heater Replacement
Leaking 50-Gallon Tank to Navien NPE-240A
A family of five in Castle Hills had a 50-gallon tank leaking from the bottom seam onto the garage floor. The unit was 13 years old, the anode rod was gone, and the third morning shower ran cold every day.
After: We drained and removed the tank, ran a new vent and condensate line, and installed a Navien NPE-240A. The family now runs two showers and the dishwasher at once. Gas use dropped about a third on the next bill.

Tank-to-Tankless Conversion in Old Downtown
A 1920s home near the Square had a 40-gallon tank in a closet too small for a modern replacement. The gas line was 1/2-inch, and the homeowner wanted the floor space back for storage.
After: We upsized the gas line to 3/4-inch, ran a new PVC vent through the rim joist, and mounted a Navien NPE-180A on the wall. The closet is now empty floor space, and hot water is endless.

Emergency Swap Before a Holiday in Rosemeade
A homeowner in Rosemeade called on a Friday evening with no hot water and a tank that had started to weep at the drain valve. Family was arriving the next morning.
After: We isolated the water and gas, drained the tank, and installed a Navien NPE-180A from truck stock. The unit was fired and tested by 9 p.m. Hot water was back before the guests arrived.

Problems Our Navien Replacement Solves in Carrollton
Most calls start with one of these four problems. Each one has a clear fix, and none of them get better by waiting.
Ask a pro →No hot water at all
We diagnose the unit, and if replacement is the answer, we install a Navien tankless the same day. You get hot water back the same evening, and we haul the old unit away.
Running out of hot water
A Navien NPE-240A delivers up to 11 GPM, enough for simultaneous showers and appliances. We size the unit to your fixture count so you never stagger showers again.
Leaking tank or rusty water
We shut off the water, drain the unit with a pump, and replace it. If the tank is rusted through, we quote a Navien tankless so you are not buying another steel tank in ten years.
Popping noises and sediment
We flush the system and inspect the anode rod. If the tank is too far gone, we replace it with a Navien and set you up on an annual descaling schedule that keeps efficiency high.
Transparent pricing
Navien Replacement Pricing in Carrollton
$2,400 - $5,500 depending on scope
Typical 2026 pricing in Carrollton runs $2,400 to $3,800 for a straight tankless swap and $3,500 to $5,500 for a tank-to-tankless conversion. The unit itself is the biggest line item, followed by gas and venting work. We quote a flat range before we start, and the price does not move unless you approve extra work. If you are comparing quotes for Navien water heater replacement and installation Carrollton GA, ask whether the price includes the permit, the haul-away, and the condensate line. Ours does.
A Navien tankless unit lasts about 15 years with annual service, roughly double a tank, and runs at 0.95 UEF. The gas savings alone often cover the price difference over the unit's life.

An NPE-180A costs less than an NPE-240A, and a combi NCB unit that also handles space heating sits at the top of the range. We size to your fixture count so you are not overbuying capacity.

A straight swap on an existing 3/4-inch line adds nothing. Upsizing from 1/2-inch, adding a regulator, or running a new line from the meter adds $400 to $1,200 depending on the run.

Carrollton Navien Replacement Reviews
★★★★★
“Our 50-gallon tank was leaking in the garage on a Friday morning. I called at 9 and had a Navien NPE-240A on the wall by 4 that afternoon. The tech ran a new vent, checked gas pressure, and walked me through the display. Two showers and the dishwasher at once now, no problem. Price matched the quote exactly.”

“I manage three rentals near the Square and needed a unit swapped between tenants fast. They pulled the old tank, installed a Navien, and had the place ready for the next renter in one day. They documented everything and left the utility closet cleaner than they found it. I have used them twice since.”

“We kept running out of hot water with two teenagers in the house. They quoted a tank-to-tankless conversion, upsized the gas line, and finished in about seven hours. The gas bill dropped noticeably the next month. The tech explained the annual descaling and even left the vinegar ratio written on the unit.”
