What your neighbors are saying about us

Patrick was very professional! I cannot recommend him highly enough, and whatever company he is working for. I very much liked their maintenance plan. He explained it very well and we purchased it. I highly recommend this plan, this company and this technician.

We absolutely love Hunters for all our electrical needs. We had originally called them out bc someone redoing our floors had burned up an outlet. Christopher was very knowledgeable and polite. He explained all recommendations that he had in a way that I understood. They are the only company I will use for all our electrical needs and upgrades.

I am very pleased with the service I've received from Hunter Service Group. Stacy was kind, respectful of my home, and professional. The install was performed in a timely fashion and I couldn't be more pleased. I will use Hunter Services for any future needs that I have within your scope! Thank you!

I highly recommend Hunter Service Group. We have recently worked with Noe Garcia and Tony Ruiz to help my in-laws find the right home generator for them to add some peace of mind if the power goes out. Installation should take place in the next few weeks. It has been a great experience so far.

Signs Your Water Heater Needs to Be Replaced

Most water heaters last between 8 and 12 years, but San Antonio’s hard water can shorten that lifespan. Mineral deposits from the area’s high mineral content build up inside the tank over time, reducing efficiency and accelerating wear. If you’re seeing any of the following, it may be time for a replacement rather than another repair:

Your water heater is 10 years old or older and showing signs of wear.
You’re running out of hot water faster than you used to.
The water coming out has a rusty color or metallic taste.
You hear popping or rumbling noises from the tank during operation.
There’s visible corrosion, rust, or moisture around the base of the unit.
Your energy bills have risen without a clear explanation.
You’ve needed multiple repairs in the past year or two.

Water Heater Types and Options to Choose From

There’s no single water heater that’s right for every home, and Hunter Service Group takes the time to walk you through your options before recommending anything. We install all major types of residential water heaters, including:

Traditional tank water heaters that store and maintain a set volume of hot water, available in gas and electric models.
Tankless water heaters heat water on demand for greater energy efficiency and an endless supply of hot water.
Heat pump water heaters that use electricity more efficiently by pulling heat from the surrounding air.
Water softener pairings to help combat San Antonio’s hard water and extend the life of your new unit.

Benefits of Upgrading to a New Water Heater

Replacing an aging water heater isn’t just about restoring hot water. A newer unit can genuinely improve your home’s efficiency and your family’s comfort. Benefits of upgrading include:

Lower monthly energy costs with a more efficient unit, especially when switching to a tankless model.
Consistent hot water throughout your home without running out mid-shower.
Reduced risk of leaks, water damage, and unexpected failures from an aging tank.
Better performance in San Antonio’s hard water conditions with a properly sized, modern unit.
Manufacturer warranty coverage that gives you protection and peace of mind on your investment.
A smaller footprint if you choose a tankless model, freeing up space in your utility area.

Our Water Heater Installation and Replacement Process

Hunter Service Group makes the replacement process as smooth as possible from start to finish. We begin with an assessment of your current setup and a conversation about your household’s hot water needs, usage habits, and budget. From there, we recommend the right unit for your home and provide upfront, flat-rate pricing before any work begins.

On installation day, our technicians handle everything, including removing and disposing of the old unit, installing the new water heater, and testing the system to make sure everything is working correctly. We check all connections, verify proper temperature settings, and walk you through the new unit before we leave. Your home will be left clean, and you’ll have hot water ready to go the same day.

Frequently Asked Questions

How do I know whether to repair or replace my water heater?

If your unit is under 8 years old and the issue is minor, a repair usually makes sense. If it’s older, the repair is costly, or problems are becoming frequent, replacement is typically the better long-term value. We’ll give you an honest assessment either way.

How long does water heater installation take?

Most installations are completed in two to three hours. If additional work is needed, such as upgrades to gas lines or electrical connections, we’ll let you know before we begin.

Is a tankless water heater worth it in San Antonio?

For many San Antonio homeowners, yes. Tankless units are more energy-efficient, provide hot water on demand, and tend to last longer than traditional tank models. They can be a smart investment, particularly for households with higher hot water demands.

How does hard water affect my water heater?

San Antonio’s hard water causes mineral scale to build up inside the tank and on heating elements over time. This reduces efficiency, increases energy use, and shortens the life of the unit. A water softener can help protect your new water heater and extend its lifespan.

Do you haul away the old water heater?

Yes. Our technicians remove and dispose of your old unit as part of the installation service so you don’t have to worry about it.
