Water Heater Replacement in San Marcos, TX

Trusted Hot Water Heater Installation Since 1996

Whether your hot water isn't working at all, or is simply not staying hot long enough for you to shower, you can count on the team at Reliable Air for expert water heater repair in San Marcos, TX.  We will always try to repair your water heater rather than replace it, but sometimes it makes more financial sense to get a new water heater instead of repair your old one. 

Signs You Need a Water Heater Replacement

  • Water leakage around tank: Water leakage isn't always a guaranteed sign you'll need a replacement. But it's a major red flag if it comes from a crack in the tank. If you do see a crack, contact Reliable Air right away.
  • Uneven temperatures or no hot water: Is your water heater notoriously unreliable? Maybe it's only working for a few minutes at a time, or worse, not at all! There's no guarantee you'll need a replacement here, but when combined with other signs, you'll definitely want to consider a new system.
  • Constant repairs: If you've called plumbers to your home multiple times to fix your tank water heater, chances are deeper issues aren't being addressed. Constant repairs indicate that the system is on its last leg and needs replacement. This is especially true if the system is 15+ years old.
  • Increased usage limiting hot water: If you've had a few additions to your family but haven't replaced your water heater for a while, it may be time for an upgrade. We can help size your new water heater so you won't have to worry about hot water running out!
