Why do water heater prices vary?

Three things change the price: electric or gas, the size in gallons, and whether the tank is tall or medium.

Everything else — labor, haul-away, testing — is the same on every job, which is why we can post the whole price online instead of quoting it in your kitchen.

Can I get a water heater price online without someone coming out?

Yes. That is how we work: you see the price online, book at that price, and no salesperson visits your home first.

How do I find out what size water heater I have?

The size in gallons is printed on the sticker on the side of the tank, usually near the model number.

If the sticker is faded, send us a photo of it with your phone number and our team will read it and text you your price.

It is on the silver or white sticker on the side of the tank, usually at eye level or a little below, on the line labeled Model, Model No. or MOD.

How long do water heaters last in the Rio Grande Valley?

Most tanks we see here last somewhere around 8 to 12 years, and hard water tends to push that toward the shorter end.

Does hard water shorten water heater life?

Yes. Valley water leaves mineral scale in the bottom of the tank, which makes the heater work harder and wear out sooner.

Draining a few gallons from the tank once a year helps. A popping or rumbling sound usually means scale has built up.

What are the signs my water heater needs replacing?

Rusty or brown hot water, water pooling under the tank, popping or rumbling sounds, or hot water running out much sooner than it used to.

My water heater is leaking, what should I do right now?

Turn off the cold water valve on top of the heater, turn off the power at the breaker for an electric unit or set the gas valve to OFF for a gas unit, then call 956-686-6656 — phones are answered 24/7.
