Two new gas water heaters with expansion tanks installed side by side by The Right Guyz

If you’re standing in a cold shower, or you just found a puddle around the bottom of your water heater, you’re probably wondering what a new one is going to cost. We think you should know that before you call, so we post our prices.

A standard 40-gallon electric water heater replacement (not in the attic) is $2,850 before taxes. That price includes the expansion tank, an atmospheric vacuum breaker and two new flexible water supply connections. It comes with our 1-year parts and labor warranty, and manufacturer coverage is typically 6 years, depending on the brand and model. You can see every water heater price we’ve published on our prices page.

Signs your water heater is on its way out

Water heaters usually give some warning before they fail completely. Watch for these:

  • Water pooling around the base of the tank, or rust stains on the floor
  • Rusty or brown hot water, while the cold water looks clear
  • Popping, rumbling or banging sounds when the heater runs
  • Hot water that runs out much faster than it used to
  • A tank that’s more than 10 years old (the date is usually on the label)
  • A relief valve that drips or keeps opening

A little noise can mean sediment buildup, which a flush may fix. A leak from the tank itself can’t be repaired, and it can go from a drip to a flood without much notice.

San Antonio’s hard water and your water heater

Most San Antonio tap water comes from the Edwards Aquifer, which runs through limestone. That makes our water hard. When hard water heats up, the minerals drop out and settle at the bottom of the tank as scale and sediment. Over time that layer insulates the water from the burner or elements, so the heater runs longer, makes noise and wears out sooner.

That’s why we recommend a yearly flush, and why a lot of our customers pair a new water heater with a water softener. It’s also why every install we do includes an expansion tank, because the pressure on a lot of San Antonio water lines runs on the high side.

Gas or electric, garage or closet

We replace both gas and electric tank water heaters in 40 and 50 gallon sizes, from brands including Rheem, Navien and other manufacturers. Gas installs include a new flexible gas connection, and we check the venting and the gas shut-off while we’re there. If you’re thinking about going tankless, we install tankless water heaters too, and we’ll give you an honest take on whether it makes sense for your household.

Straight answers from the owner

If another company has already told you what you need, Tito is glad to give you a second opinion. He’ll look at your setup, tell you what he sees, and give you options. If your heater just needs a new part, he’ll say so. If it’s time to replace it, you’ll know the full price before any work starts.

My family and I were in dire need to get her water heater fixed. It was late at night. The kids had no hot water and the owner of the company answered his phone and showed up on time. What a great guy I can't say enough and as he was there, I decided to ask him several questions About some previous work we did and what else might need to be done that he thought.

Water Heater Replacement questions

How long does a water heater last in San Antonio?

Most tank water heaters last somewhere around 8 to 12 years. San Antonio's hard water can shorten that, because minerals settle in the bottom of the tank and make it work harder. A yearly flush helps a lot.

Why does a new water heater need an expansion tank?

When water heats up it expands. In homes with a check valve or pressure reducing valve on the main line, that extra pressure has nowhere to go, so it strains the tank, the relief valve and your fixtures. An expansion tank gives it somewhere to go. It's included in our posted replacement price.

Should I repair my water heater or replace it?

If the tank itself is leaking, it needs to be replaced. If the problem is a part like a thermostat, heating element, gas valve or thermocouple on a heater that's still fairly young, a repair can make sense. We'll tell you which way we'd go if it were our house.

Can you replace a water heater the same day?

It depends on the model and where the heater sits. Call us and we'll give you a realistic timeline.
