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 a New Water Heater

Water heaters usually give you some warning before they fail. Watch for these signs.

  • Unit over 10 years old
  • Rusty or discolored hot water
  • Leaks around the tank base
  • Running out of hot water
  • Rumbling or popping noises
  • Frequent repair calls
  • Rising energy bills
  • Inconsistent water temperature

Hard water in New Braunfels causes sediment to build up in the bottom of the tank, which wears out water heaters faster. Many local homes also have water heaters in garages or attics, where Texas heat and humidity speed up rust and corrosion. If your unit is showing several of these signs, water heater replacement in New Braunfels, TX can save you from a messy leak and a cold shower.

Benefits of Upgrading Your Water Heater

A new water heater gives you reliable hot water when you need it, without the guesswork of an aging tank. Newer models heat water more efficiently, which can help lower your monthly energy bills. They also tend to run quieter and recover faster after heavy use.

Professional water heater installation in New Braunfels, TX also protects your home. An old tank sitting in an attic or garage can leak without warning and cause serious water damage. Replacing it before it fails gives you more control over the timing and the cost.

Upgrading is also a chance to choose a system that fits your household’s actual hot water use. A growing family, a new bathroom, or a home in a newer community like Veramendi or River Chase may need more capacity than the original unit offered.

Water Heater Options for Installation

There’s no one-size-fits-all water heater. If you’re planning a water heater replacement in New Braunfels, TX, it’s a good time to look at all your options. Our technicians will walk you through the pros and cons of each without pushing you toward something you don’t need.

Traditional Tank Water Heaters

Tank water heaters store and heat a set amount of water, usually 40 to 80 gallons. They’re available in gas and electric models and are a dependable, budget-friendly choice for many homes. They’re also the most familiar option for most homeowners.

Tankless Water Heaters

Tankless units heat water on demand instead of storing it in a tank. That means you don’t run out of hot water during back-to-back showers, and they take up much less space. They often cost more upfront but can last longer and use less energy over time. 

Hybrid Heat Pump Water Heaters

Hybrid water heaters draw heat from the surrounding air to warm your water, making them very energy-efficient. They work especially well in warm climates like ours. As a bonus, they remove some moisture from the air, which can help in humid New Braunfels garages. 

Our Water Heater Installation & Replacement Services

Every water heater installation starts with a review of your current setup and hot water needs. We check the size of your household, your fuel type, and the space where the unit will go. Then we recommend the right system and give you an upfront price before any work begins.

On installation day, we safely disconnect and remove your old water heater and haul it away. We install the new unit, connect the water and gas or electrical lines, and ensure safety components, such as the pressure relief valve, are functioning properly. For attic installations, we pay close attention to drain pans and venting to help protect your ceilings.

Before we leave, we test the system, check for leaks, and show you how everything works. Financing options are available to help you manage the cost of a new water heater. Whether you’re in an older home near downtown or a newer build in Gruene, we’ll get the job done cleanly and correctly.
