Why you shouldn’t skip your Gas Heater’s Annual Service

Gas heaters are great for keeping warm, but they can be deadly if not maintained properly. Manufacturers recommend servicing gas heaters once per year. If gas heaters are faulty or poorly maintained, they can leak carbon monoxide. Carbon monoxide can be lethal as it can’t be seen and has no smell. It can cause death or chronic illness. Carbon monoxide poisoning can happen in any home or building with gas heating appliances, including newer ones. Gas heaters need to be serviced annually by fully qualified gas fitters who have the right equipment to test for carbon monoxide leakage.

The Importance of an Annual Service

Gas heaters are a popular choice for households and businesses as they provide warmth and comfort during colder months. However, it is essential to ensure that your gas heater is operating safely and efficiently, which is where an annual service comes into play.

During an annual service, a licensed gas fitter will thoroughly inspect and test all aspects of your gas heater, including the pilot light, burner, fan, thermostat, and safety controls. They will also check for any leaks and carbon monoxide emissions to ensure that your heater is not only operating efficiently but safely as well.


Regular maintenance of your gas heater not only improves its performance but also increases its lifespan. By servicing your gas heater annually, you are investing in the longevity of your appliance, avoiding the need for costly repairs or replacements in the future.

Additionally, an annual service can help detect any potential issues before they become bigger problems. Ignoring small issues could result in your gas heater malfunctioning or even causing dangerous situations such as gas leaks or carbon monoxide poisoning.

What Happens During an Annual Service?

During an annual service, a qualified technician will perform a thorough inspection of your gas heater. They will check for any signs of wear and tear, such as rust or cracks in the unit, and replace any damaged components if necessary. They will also clean the inside of the heater and if present, replace the air filter to ensure proper air flow and ventilation.

In addition, the technician will test the heater’s safety controls, such as the thermostat and carbon monoxide detector, to make sure they are functioning properly. They will also check the pilot light and gas pressure, and make any necessary adjustments to ensure the heater is operating efficiently and safely.

What if I Don’t Service My Gas Heater?

Skipping your gas heater’s annual service can lead to a host of problems down the line. Without regular maintenance, your gas heater may start to function inefficiently and even become dangerous. First and foremost, an unserviced gas heater can become a carbon monoxide risk. This odourless and colourless gas can build up if the unit isn’t functioning properly, potentially leading to serious health problems or even death. On top of that, a poorly maintained gas heater can also become a fire hazard. Built-up debris in the unit can cause the ignition system to fail or the gas to combust improperly, leading to a potential house fire. And even if your unserviced gas heater doesn’t cause a safety issue, it will likely start to operate less efficiently. A unit that’s running poorly will take longer to heat up your home, which means you’ll need to spend more money on your energy bills. Plus, if your gas heater is under warranty, failing to service it annually may void that warranty.

In short, skipping your gas heater’s annual service is a dangerous and expensive mistake. Don’t put yourself or your family at risk – make sure to book an annual service with a licensed professional.
