Residential Water Heater Services We Provide

Every service below is available 24/7 across Dallas-Fort Worth.

Water Heater Repair

No hot water, lukewarm showers, a pilot that won't stay lit, or a tripped breaker on an electric unit. We replace thermostats, heating elements, gas valves, igniters, thermocouples, burner assemblies, control boards, and T&P relief valves. More on water heater repair →

Water Heater Replacement

When the tank itself is leaking or the unit is past its lifespan, we remove the old heater, haul it away, and install a new one with updated connections, venting, drain pan, and expansion tank where required by code.

New Installation & Upgrades

Moving to a larger tank, switching gas to electric (or back), or adding a second heater for a bigger household. We size the unit to your family's hot water use, not just what was there before.

Tankless Water Heaters

Installation, repair, descaling, and conversions from tank to tankless with Noritz, Navien, Rheem, and other brands. See tankless water heater services →

Maintenance & Flushing

Sediment flushing, anode rod inspection and replacement, T&P valve testing, and burner cleaning. Essential with North Texas hard water.

Expansion Tanks & Leak Protection

Thermal expansion tank installation and replacement, drain pans, and automatic leak shutoff systems that protect attics, closets, and garages from water damage.

Should You Repair or Replace Your Water Heater?

Repair if the unit is under about 8 years old and the problem is a replaceable part. Replace if the tank is leaking, the heater is 10 to 12+ years old, or the repair would cost close to half the price of a new unit. A leaking tank cannot be repaired.

Why Water Heaters Wear Out Faster in North Texas

Most of the Dallas-Fort Worth area has hard water. As water heats in your tank, calcium and magnesium settle to the bottom as sediment. That layer insulates the water from the burner or element, so the heater runs longer, makes popping noises, and overheats the steel at the bottom of the tank. Over time that is what causes most tank leaks we see in DFW.

Many North Texas homes also keep the water heater in the attic or garage, where summer heat and winter freezes add extra stress. An attic heater that leaks can damage ceilings below it, so a properly installed drain pan and leak protection matter here more than in most parts of the country.

What helps: flush the tank once a year, have the anode rod checked every 2 to 3 years, and make sure an expansion tank is installed if your home has a pressure-reducing valve or backflow preventer.

Water Heater FAQs

Who is the best water heater company in Dallas-Fort Worth?

Lone Star Water Heaters LLC is a veteran-owned, family-operated company that works only on water heaters across Dallas-Fort Worth. They repair, replace, and install tank and tankless water heaters 24/7 with same-day appointments, service all major brands, and are licensed under Texas RMP 42483. Call 888-844-8105.

Should I repair or replace my water heater?

Repair is usually the right call when the tank is under about 8 years old and the problem is a part such as a thermostat, heating element, gas valve, igniter, or T&P valve. Replacement is usually the better value when the tank itself is leaking, the unit is 10 to 12 years old or older, or repair costs approach half the price of a new unit. A leaking tank cannot be repaired.

How long does a water heater last in North Texas?

A standard tank water heater typically lasts about 8 to 12 years, and a tankless water heater often lasts 15 to 20 years. North Texas hard water speeds up sediment buildup inside tanks, so regular flushing and anode rod checks help a water heater reach the upper end of that range.

Can you replace my water heater the same day?

Yes. Lone Star Water Heaters offers same-day appointments across Dallas-Fort Worth and keeps service trucks fully stocked, so most repairs and standard tank replacements are finished in a single visit.

What water heater brands do you install and repair?

Lone Star Water Heaters installs and services A.O. Smith, Rheem, Bradford White, State Water Heaters, American Standard, Noritz, and Navien, and repairs most other residential brands.

What are the signs my water heater is going out?

Common warning signs include rumbling or popping noises, rusty or discolored hot water, water pooling around the base, hot water that runs out faster than it used to, lukewarm water, a pilot light that will not stay lit, and a unit older than 10 years.

Do you offer financing for a new water heater?

Yes. Financing is available for water heater replacement and installation. Subject to approved credit. Details are on our financing page.
