Cost of Tank Water Heater Repairs in San Marcos
At Reliable Air, we believe that repairing your water heater shouldn’t cost you an arm and a leg. That’s why we offer fair, affordable prices for our repair services.
Factors that affect the cost of water heater repairs:
- Age of the water heater: The age of the water heater can significantly impact the cost of the repair. Older water heaters may require more extensive repairs, and replacement parts may be harder to find, resulting in higher costs.
- Gas versus electric models: Generally, gas water heaters tend to be more expensive to repair than electric water heaters. This is because gas water heaters are more complex and require specialized training to repair, as they involve gas lines, combustion chambers, and other components that require more expertise to fix. Additionally, gas water heater parts can be more expensive to replace than the heating elements and thermostats found in electric water heaters.
- The type of repair: Minor repairs such as replacing a thermostat or valve are generally less expensive than major repairs like replacing a heating element or fixing a leak. Leaks are particularly difficult to repair, and depending on the severity of the hole or tear, you may end up needing a tank replacement. At Reliable Air, we perform thorough evaluations to identify problems and determine necessary repairs. Then, we’ll present solutions that align with your budget needs.

As a contractor myself, I’ve worked with Reliable on several projects in the past. Knowing their quality of work, when I needed work on my own home I knew who to call. Arrived on schedule. Diagnosed to problem and fixed it quickly. Travis was friendly and helpful and answered my questions. I would recommend them to anyone.

When I called to request service they were able to send someone out that same day. When Edgar arrived he was polite and courteous. He explained what he was going to complete the diagnostics first. He then explained what needed to be done and made sure I understood. It was very appreciated that he gave me time to decide on my repair because it was going to cost a bit of money. He finished quickly and explained the invoice. Great job!
