Overview

Repair or replacement, sized for your home

No hot water, rusty water, popping sounds, or a heater that can't keep up? We diagnose whether a repair makes sense or a replacement is the smarter long-term call — and we tell you honestly, with the numbers to back it up.

Considering tankless? We'll walk you through the trade-offs: endless hot water and lower standby losses versus higher upfront cost and gas/venting requirements. Whatever you choose, we size it correctly for your household's real demand.

FAQ

Water heater questions, answered

How long does a water heater last in North Texas?

Tank units typically last 8–12 years here — often toward the shorter end, because DFW's hard water accelerates sediment buildup. Annual flushes and anode-rod checks meaningfully extend that life. Tankless units, properly maintained, commonly run 15–20 years.

Should I repair my water heater or replace it?

If the tank itself is leaking, or the unit is past about 10 years old, replacement is almost always the better spend. For younger units with a failed thermostat, element, or valve, repair usually wins. We quote both options side by side so you can decide.

Is a tankless water heater worth it?

Tankless gives you endless hot water and lower standby losses, but costs more upfront and may need gas-line or venting upgrades. It's a great fit for some homes and overkill for others — we walk you through the trade-offs and size either option to your household's real demand.

Why is my water heater making popping or rumbling noises?

That sound is water boiling up through a layer of sediment on the tank bottom — very common with DFW hard water. A flush can quiet a younger unit and slow the wear; on an older tank it's often an early warning that the end is near.
