How to Know When to Repair or Replace Your Water Heater

August 22, 2025

If your water heater isn’t working like it used to, it can throw off your daily routine and even cause damage if left unchecked. You’re probably wondering: should I fix it or get a new one? It’s a common question—and the answer isn’t always simple.

This guide will help you understand the signs that your water heater needs attention, explain when repairs make sense, and when replacement might be the better choice. Our goal is to help you feel confident in making the right decision for your home, your budget, and your comfort.

Signs Your Water Heater Needs a Closer Look

It’s not always obvious when a water heater is failing. Here are some common warning signs that mean it’s time to schedule an inspection:

  • Not enough hot water or no hot water at all
  • Inconsistent water temperature (too hot or too cold)
  • Visible leaks or moisture around the unit
  • Water looks rusty or discolored
  • Strange noises like popping or rumbling

If you notice any of these, it’s important to get a professional to assess the situation before the problem gets worse or causes damage.

When Should You Consider Replacing Your Water Heater?

Water heaters don’t last forever. Most traditional tank models have an average lifespan of about 8-12 years. Tankless water heaters can often last 15-20 years, but this depends on how hard your water is, how much you use the system, and how well you maintain your water heater.

To find out your water heater’s age, check the serial number on the manufacturer’s label or sticker. Sometimes it is encoded in the serial number so you may have to contact the manufacturer to find out. Even if you’ve kept up with regular maintenance, an older unit may not be as reliable or efficient as newer models.

As your water heater approaches the 10-year mark, repairs might become less effective or more frequent, so replacement becomes a more practical option.

Balancing Cost: Repair vs. Replacement

One big factor in deciding whether to repair or replace is the cost comparison. Deciding if putting money into an aging water heater make sense can be tough. Our Technicians are trained to look at all the angles to help you figure out what makes the most sense for your specific situation.

Newer water heaters are usually much more energy-efficient. That means you could save money on your utility bills each year, which can help offset the initial cost of a new unit.

Check if your water heater is still under warranty. Manufacturers provide 6 to 12 year warranties. If yours is still covered, repairs will cost less.

Taking advantage of available rebates before they’re gone is another key factor to consider.

Comfort and Convenience Matter Too

Sometimes it’s not just about repairs or costs, your comfort matters. If your water heater is too small for your household’s needs, you might run out of hot water during normal use. It might be time for a larger unit.

Major problems like broken control valves or significant corrosion usually mean replacement is the safest choice. In these cases, repairs may only be a temporary fix.
