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.

Warning Signs Your Water Heater Needs Repair

Water heaters usually give warning signs before they fail completely. San Antonio’s hard water is particularly tough on water heater components, causing mineral scale to build up on heating elements and inside the tank faster than it would in areas with softer water. Catching problems early can save you from a much bigger headache down the road. Watch for:

Your hot water runs out much faster than it used to.
Water comes out of the tap lukewarm even when set to a higher temperature.
You hear popping, rumbling, or banging sounds coming from the tank.
The water has a rusty tint or an unusual metallic smell.
You notice moisture, pooling water, or corrosion around the base of the unit.
The pressure relief valve is leaking or discharging water.
Your energy bills have increased without any change in your usage habits.

Common Water Heater Problems We Resolve

Many water heater problems are repairable, and our technicians have the experience to diagnose them accurately the first time. In San Antonio, hard water scale and sediment buildup are among the most frequent causes of water heater trouble, but we handle the full range of issues that come up with both tank and tankless systems. Common problems we see and fix include:

Sediment and scale buildup reduce heating efficiency and cause noise.
Failed heating elements in electric water heaters leave you with cold water.
Faulty thermostats that cause inconsistent or incorrect water temperatures.
Damaged or worn anode rods accelerate corrosion inside the tank.
Leaking pressure relief valves that need to be tested or replaced.
Pilot light and ignition issues in gas water heaters.
Burner problems are affecting heat output on gas-powered units.

Frequently Asked Questions

How do I know if my water heater needs repair or full replacement?

Age and repair history are the biggest factors. If your unit is under 10 years old and the issue is isolated, repair usually makes sense. If it’s older or has needed repeated fixes, replacement may be the smarter investment. We’ll give you an honest recommendation after assessing the unit.

Why is my water heater making rumbling or popping noises?

These sounds are typically caused by sediment buildup at the bottom of the tank. In San Antonio, hard water accelerates this process. Flushing the tank can often resolve the noise and restore efficiency, though heavily scaled units may need more attention.

Can a leaking water heater be repaired?

It depends on where the leak is coming from. Leaks from fittings, valves, or supply lines are usually repairable. A leak from the tank itself typically means the unit needs to be replaced. Our technicians will locate the source and tell you which direction makes the most sense.

How long does a water heater repair take?

Most repairs are completed in a single visit, often within one to two hours. If parts need to be ordered or the situation is more complex, we’ll let you know upfront so you can plan accordingly.

Does hard water really affect water heaters that much?

Yes. San Antonio’s water has a high mineral content, and that scale builds up inside the tank and on heating elements over time. It reduces efficiency, increases energy use, causes noise, and shortens the life of the unit. Regular maintenance and a water softener can help slow that process significantly.
