Water Heater Repair

Dealing with a broken water heater is stressful. Our team is ready to troubleshoot and repair a wide range of issues affecting both traditional tank-style and tankless units. Common problems we fix include:

  • No Hot Water: This could be due to a tripped circuit breaker or blown fuse (electric), a faulty thermostat, a problem with the heating element (electric), or a pilot light issue or thermocouple problem (gas).
  • Not Enough Hot Water: Possible causes include a thermostat set too low, a failing heating element, sediment buildup in the tank, or simply having an undersized unit for your household's needs.
  • Strange Noises: Popping or rumbling sounds often indicate sediment buildup in the bottom of a tank. Hissing sounds can be leaks.
  • Leaking Water Heater: Leaks can come from various points, including the temperature and pressure relief (T&P) valve, drain valve, or connections. A leak from the tank itself often signifies internal corrosion and the need for replacement.
  • Discolored or Smelly Water: Rusty water could indicate a failing anode rod or rust inside the tank. Foul odors might suggest a bacterial issue that needs flushing and disinfection.
  • Pilot Light Issues (Gas): If your pilot light keeps going out, there could be a problem with the thermocouple, the gas valve, or a draft issue.
  • Thermostat Malfunctions: A faulty thermostat can lead to inconsistent water temperature or no hot water at all.
  • Heating Element Problems (Electric): When a heating element fails, it prevents the water from heating properly.

Our technicians will perform a thorough inspection to pinpoint the root cause of the problem and recommend the necessary repairs. We carry common parts on our trucks to facilitate swift fixes whenever possible.

Water Heater Installation and Replacement

Whether you're installing a water heater in a new home or replacing an old, inefficient unit, choosing the right system and ensuring proper installation is crucial. We install all types of water heaters, including:

  • Traditional Tank Water Heaters (gas and electric)
  • Tankless Water Heaters (gas and electric)
  • Heat Pump Water Heaters

We can help you evaluate your hot water needs, energy usage goals, and budget to select the best Water Heaters for your San Antonio home. Our installation process includes safely disconnecting and removing your old unit, expertly installing the new one according to manufacturer specifications and local codes, and testing the system to ensure it functions perfectly before we leave. Proper installation is key to efficiency, safety, and longevity.

Water Heater Maintenance

Regular Water Heater Maintenance is often overlooked but is vital for extending the life of your unit, maintaining efficiency, and preventing unexpected breakdowns. This is especially true in San Antonio due Antonio's hard water. Our maintenance service includes:

  • Flushing the Tank: This removes sediment buildup, which is common with hard water. Sediment reduces efficiency, can cause noise, and shortens the lifespan of tank-style heaters.
  • Inspecting the Anode Rod: The anode rod is a sacrificial metal rod that attracts corrosive elements in the water, protecting the tank lining. In areas with hard water, the anode rod can corrode quickly and needs regular inspection and potential replacement.
  • Checking the Thermostat and Heating Elements/Burner Assembly: Ensuring these components are functioning correctly is essential for consistent heating.
  • Testing the Temperature and Pressure Relief (T&P) Valve: This is a critical safety feature that prevents the tank from overheating or over-pressurizing.
  • Inspecting for Leaks: We check all connections, valves, and the tank itself for any signs of leaks.
  • Checking Venting (Gas Heaters): Proper venting is necessary for safety to ensure combustion gases are expelled correctly.

We recommend annual maintenance for most water heaters to proactively identify potential issues and keep the system running smoothly.

Addressing San Antonio's Hard Water

San Antonio's water is known for its hardness, meaning it contains high levels of dissolved minerals, primarily calcium and magnesium. While safe to drink, hard water can significantly impact plumbing fixtures and appliances, especially water heaters.

Over time, these minerals precipitate out of the water and settle at the bottom of your water heater tank as sediment. This sediment acts as an insulator, forcing the heating element or burner to work harder and longer to heat the water above the sediment layer. This reduces energy efficiency, increases utility bills, and can cause the popping or rumbling noises you might hear. More importantly, sediment buildup can lead to premature failure of the heating elements or even the tank itself by causing localized overheating.

For tankless water heaters, hard water can lead to mineral scale buildup in the heat exchanger, restricting flow and reducing efficiency.

Regular flushing is the primary way to combat sediment buildup in tank-style heaters and scale in tankless heaters. Checking and replacing the anode rod is also crucial for tank heaters to protect the tank from corrosion accelerated by hard water minerals. For a more comprehensive solution to protect your entire plumbing system, including your water heater, consider installing a Water Softener or a Water Filtration system. We can assess your water quality and recommend appropriate solutions.

When to Repair vs. Replace Your Water Heater

Deciding whether to repair your existing water heater or invest in a new one can be tough. Our technicians can help you make an informed decision based on several factors:

  • Age: A standard tank-style water heater typically lasts 10-15 years. If your unit is approaching or exceeds this age, replacement is often more cost-effective than repair, as other components are likely nearing the end of their lifespan. Tankless units can last 20 years or more with proper maintenance.
  • Frequency and Cost of Repairs: If your water heater requires frequent repairs, or if the cost of a single repair is close to half the cost of a new unit, replacement is usually the better long-term investment.
  • Efficiency: Older water heaters are significantly less energy-efficient than newer models. Upgrading can lead to noticeable savings on your energy bills.
  • Signs of Tank Failure: Visible rust on the tank, leaks from the tank itself (not connections or valves), or consistently discolored water are strong indicators that the tank is corroding internally and needs to be replaced.

We provide honest assessments and transparent recommendations, helping you weigh the pros and cons of repair versus replacement for your specific situation.
