Is It Time to Repair Your Gas Heater? Repair vs Replace

While some gas heater problems simply require replacing a faulty part, some problems are far more complicated — and even dangerous. It is important to have an idea of which gas heater problems require repair and which issues require immediate professional attention.

Here are 10 key questions to ask yourself to help decide if you should repair or replace your gas heater.

Common Gas Heater Problems — Repair or Replace

1. Is the Gas Heater Causing Carbon Monoxide Leaks?

Carbon monoxide is an odourless, colourless gas that can lead to serious health consequences. If your gas heater is leaking carbon monoxide, your household is at risk of carbon monoxide poisoning. In this case, the safest route is to replace the gas heater right away.

Carbon monoxide leaks need to be addressed immediately to keep yourself and your loved ones safe. Along with replacing your gas heater, be sure to have a carbon monoxide detector installed in your household.

Leaky gas heaters also put your home at risk of a gas explosion. If you detect any gas leaks, contact a professional immediately to get it replaced.


2. Is It An Old Gas Heater?

If your gas heater is over a decade old, it may be time to consider replacing it. Installing a newer model will likely lead to a drop in your energy bills, increased safety, and improved function.

Old gas heaters are more likely to experience problems, including CO leaks, faulty parts, and inefficiency. Outdated models will also be complicated to repair as it may be difficult to find the proper replacement parts.


3. Have You Noticed a Sudden Increase in Your Energy Bill?

Has your energy bill mysteriously gone up? This may indicate issues with your gas heater, such as consuming more fuel. Upgrading to an energy-efficient gas heater may be your best option.


4. How Often Are You Having Problems with Your Gas Heater?

Whether your gas heater is new or old, constantly calling in a professional to repair it can get costly. If your gas heater needs service multiple times each year, you may want to consider a replacement.


5. Is Your Gas Heater Noisy?

Have you noticed odd rattling, rumbling, banging, or popping noises when you turn your gas heater on? A variety of factors can lead to a noisy gas heater, including:

  • A faulty fan
  • A malfunctioning motor
  • Loose ductwork
  • Faulty components

If you notice a noisy gas heater, it may be possible to repair it. When in doubt, have a gas heater professional evaluate it to determine if a simple fix will solve the issue.

6. Do You Have An Open-Flued Gas Heater?

If you have an open-flued heater, you will want to get it replaced immediately. The Victorian government has banned open-flued gas heaters due to safety concerns.

Open-flued heaters pull air from the room in order to raise the temperature. This can draw in carbon monoxide in some cases, making open-flued gas heaters dangerous. The risk of carbon monoxide poisoning from an open-flued heater is higher in newer homes that are tightly sealed to be energy-efficient.


7. Is Your Gas Heater Showing Signs of Excess Wear?

Check your gas heater for signs of excess wear, including:

  • Rust on the surface
  • Minor cracks
  • Visible damage
  • Bumps showing up in the metal

If your gas heating is showing signs of damage or wear, consider getting it replaced.


8. Is Your Gas Heater Not Producing Warm Air?

Is your gas heater failing to blow hot air? This is likely a result of built-up dust, debris, or dirt caught in the air vents.

It may also indicate a blown circuit breaker, faulty air blower, or broken fan. Cleaning the air vents may solve the issue. If needed, a professional can assess the air blower or circuit breaker and perform any necessary repairs.


9. Is Your Pilot Light Out or Flickering?

If your pilot light constantly goes out or flickers different colors, your gas heater may need repair.

Anything from clogged gas lines to air drafts can cause the pilot light to flicker. Typically, a professional can repair the faulty part to address the pilot light issue and get your gas heater up and running again.


10. Has It Been More Than a Year Since Your Gas Heater Has Been Serviced?

All gas appliances, including gas heaters, should be serviced at least once a year to comply with manufacturer warranties and instructions.
