What’s the Cost of a Water Heater Repair in San Antonio?

August 24, 2021

The cost to repair a water heater in San Antonio ranges from $298 to $785.

We know that’s not an exact answer, but without having a plumber inspect your water heater, it’s hard to say exactly what the repair will cost.

That said, the cost of a water heater repair will go up or down depending on the following factors:

  • The type of water heater you have
  • What’s wrong with your water heater
  • Whether your manufacturer warranty is valid
  • The plumber you hire for the repair

We’ll discuss each of these cost factors in more detail to give you an idea of what you could pay to repair your water heater.

Cost factor #1: The type of water heater you have

The two main types of water heaters are tank units and tankless systems. If you have a tankless water heater, you’ll likely pay more for your repair.

Why are tankless systems more expensive to repair?

Since tankless water heaters are more complex, their replacement parts are generally more expensive, raising the repair cost. Additionally, tankless repairs can be more complicated, which means it could take the plumber longer to repair the unit compared to a tank water heater.

Cost factor #2: What’s wrong with your water heater

If you have a complicated repair or an expensive part is broken, you can expect to pay more for your repair.

A few examples of expensive water heater repairs include:

  • A broken burner assembly: This is the part in a gas-powered tank water heater that actually heats the water. If it goes bad, it will be a costly repair.
  • Failed heating element: In an electric tank or tankless system, the heating element is responsible for warming up water. If it goes bad, you can expect the repair to cost more.
  • Leaks in the tank: If your tank water heater is leaking, it almost always means that you’ll need to replace the tank altogether.

Cost factor #3: The validity of your manufacturer warranty

When your water heater was installed, it came with a warranty to cover parts that fail due to a manufacturer error. Most water heater warranties last anywhere from 2 to 10 years from the day the water heater was first installed.

If your water heater warranty is still valid, you may not have to pay as much for your repair. That said, homeowners sometimes unintentionally “void” the warranty, which makes them responsible for the full cost of the repair.

Your manufacturer warranty may be void if:

  • A licensed plumber has not regularly maintained the water heater
  • The water heater was never registered with the manufacturer
  • The water heater has been repaired with parts that haven’t been approved by the manufacturer

The easiest way to check the validity of your warranty is to look up your water heater’s model number on the manufacturer’s website. You can find the model number on the rating plate printed on your water heater.

If you can’t find the warranty online, call the manufacturer of your water heater or call a plumber for help.

Cost factor #4: The plumber you hire for the repair

Unfortunately, not all plumbers keep high standards for service. Some plumbers without a lot of experience charge significantly less than their competitors. Beware of hiring these types of plumbers because they may cut corners during the repair, which can end up costing you more down the road in future repairs.

To make sure a plumber is sufficiently experienced to do high-quality work, ask yourself these questions before you hire them:

  • Is the plumber licensed and insured?
  • Does the plumber operate out of a physical office (instead of just a van)?
  • Has the plumber been in business for at least 10 years?
  • Does the plumber offer guarantees on their repair work?
  • Does the plumber have good customer reviews on sites like Google, Better Business Bureau, and Facebook?

If you answered “yes” to the questions above, chances are the plumber will do high-quality repair work for you.
