I can’t say enough good things about Thayer AC. From the first call, they were responsive and professional. They came out quickly, took the time to explain what was going on, and were incredibly honest about what did and didn’t need to be fixed. No pressure — just straightforward, trustworthy service. It’s rare to find that these days. You won’t regret calling them. I am so thankful I did. I honestly feel like I would’ve spent so much more calling anyone else. Highly recommend!!

Signs You Need Water Heater Repair

Most water heaters give you a few warning signs before they fail. Call us if you notice any of these.

  • No hot water
  • Water runs cold quickly
  • Rusty or discolored water
  • Rumbling or popping noises
  • Water is pooling around the tank
  • Rotten egg smell
  • Pilot light keeps going out
  • Fluctuating water temperature

Catching these problems early can save you from water damage and a costly emergency replacement. If something seems off, it’s worth having a technician take a look.

Common Water Heater Problems

Water heaters in New Braunfels face a few local challenges. Hard water is common in our area, and the minerals in it build up inside the tank over time. Many homes also keep their water heaters in garages or attics, where Texas heat and humidity wear down components and accelerate corrosion.

Sediment Buildup

Minerals from hard water settle at the bottom of the tank and form a layer of sediment. This makes your water heater work harder, causes popping noises, and reduces the amount of hot water you get. Left alone, it can shorten the tank’s lifespan.

Faulty Heating Elements or Burners

Electric water heaters rely on heating elements, while gas units use a burner and pilot assembly. When these parts wear out or get dirty, your water may come out lukewarm or not heat at all. These parts can usually be repaired or replaced without replacing the whole unit.

Leaks and Corrosion

Leaks can come from loose connections, a failing pressure relief valve, or a corroded tank. Humid garages and attics make rust more likely on fittings and the tank itself. Some leaks are an easy fix, while a leaking tank usually means it’s time for a replacement.

Thermostat and Valve Problems

A bad thermostat can cause water that’s too hot, too cold, or inconsistent. Faulty gas valves, temperature relief valves, and pressure relief valves can also affect performance and safety. These issues should be checked by a professional rather than handled as a DIY project.

Our water heater repair service in New Braunfels, TX, covers both gas and electric units, including traditional tank and tankless models. Whether you live in Gruene, Mission Hills, River Chase, or one of the newer neighborhoods around town, we’ll come to you ready to work.

We start by inspecting your water heater to identify the root cause of the problem. Then we explain what we found in plain language and give you an upfront price before any work begins. There are no hidden fees and no pressure to buy something you don’t need.

Once you approve the repair, our technicians fix the issue using high-quality parts and test the system to ensure everything is working properly.

Winter cold snaps in New Braunfels can be especially hard on water heaters. Colder incoming water makes the unit work harder, and older systems often fail right when you need them. If your water heater fails during a freeze, give us a call, and we’ll get there as quickly as we can.

Frequently Asked Questions

How much does water heater repair in New Braunfels, TX cost?
The cost depends on the type of water heater and what’s wrong with it. We give you an upfront price before any work begins, so there are no surprises.

If your water heater is fairly new and the problem is a single part, repair is usually the better option. If the tank is leaking or the unit is near the end of its life, replacement often makes more sense.

Traditional tank water heaters typically last about 8 to 12 years, while tankless units often last longer. Hard water and skipped maintenance can shorten that lifespan.

Popping or rumbling usually means sediment has built up at the bottom of the tank. Flushing the tank can often help, but heavy buildup may need professional attention.

Yes, we repair both tank and tankless water heaters, including gas and electric models. Our technicians can diagnose the problem and recommend the right fix.
