Benefits of a regular heater service
The benefits of a regular heater service
Gas, ducted and split-system heaters all need to be serviced regularly to help improve efficiency, reduce running costs and protect your health.
Autumn and winter in Victoria are seasons when puffer jackets, beanies and scarves emerge from summer hibernation. It’s also a time when household heaters can be on for 10 hours or more, after months of inactivity.
Not surprisingly, emergency heater repairs become more common when cold weather hits and heaters are suddenly switched back on. More than 4,000 RACV Emergency Home Assist heater repairs were undertaken in 2024, with callouts spiking in June and July, during Victoria’s coldest period.
Issues such as power faults, overheating, low gas pressure and faulty fans are some of the reasons for these callouts.
While you might think your heater can work tirelessly year after year, a regular heater service by a qualified professional can help negate the chances of costly emergency repairs when you need your heater most.
Benefits of a regular heater service
Improve air quality and safety
If your heater is unserviced and clogged from years of use and neglect, the hot air it emits may contain dirt, mould and bacteria.
"A regular heater service will ensure the major parts are thoroughly cleaned, improving the air quality in your home and the safety of those inside it," says RACV Trades Senior Product Manager Nathan Tayeh.
"If you have a gas heater, it is recommended that these heating systems are serviced every two years, which includes checking carbon monoxide levels."
A carbon monoxide leak is a threat to your health and safety. A leak cannot be seen or smelt, and can contribute to your household feeling dizzy and nauseous.
Rental properties with a gas heater (or other gas appliances) must have a gas safety check carried out every two years. This should be arranged and paid for by the rental provider and be carried out by a licensed gas fitter.

Reduce running costs and increase energy efficiency
Heating the home can be a huge contributor to energy bills and depending on the size of the rooms you’re heating and your heating system, the costs vary significantly.
According to Sustainability Victoria, the running costs for heating in a medium (160sqm) home can vary from around $1,200 per year for a multi-split reverse-cycle air conditioner system all the way up to more than $2,700 for ducted gas heating.
Tayeh says these running costs are likely to increase if your heater is working less efficiently.
"A heater technician will typically carry out several checks when servicing a heating system including testing the airflow, thermostat calibration, inspecting the duct work, and cleaning and changing the air filter – all of which contribute to an efficient heating unit that minimises energy consumption," he explains.

Having your heater cleaned and serviced regularly to maintain efficiency and prevent costly repairs.
Increase the lifespan of your heater
The lifespan of your heater doesn’t just depend on how frequently you use it. Factors outside of your control, such as dust and weather events, can impact the longevity and effectiveness of your heater system.
"A professional heater technician will examine the inner components of your heating system during a routine service, identifying any hidden issues and potential problems that could become a lot more costly and complex the longer they’re left," Tayeh says.
While most manufacturers advertise a lifespan of around 15-20 years for a new heater system, this is only if the system is properly maintained, according to the manufacturers’ recommendations.
Without regular servicing, your heater may last fewer than 15 years - meaning you may end up needing to spend thousands of dollars for a replacement unit ahead of time.
When should I service my heater?
To help avoid losing heating during the coldest months of the year, aim to have your heater serviced professionally before winter hits.
If you use reverse-cycle split-system air conditioners for heating, it’s also a good idea to additionally clean the filters during their peak usage period (generally between June and August).
How often should I service my heater?
The frequency of servicing depends on the type of heater or heaters in your home.
Gas heaters and ducted heating systems should be serviced at least once every two years. Consider servicing it annually if your gas or ducted system is old or you use it heavily.
Most air conditioner manufacturers recommend an annual service.
