How Often Should a Heater Be Serviced?
A heater should be serviced at least once a year, ideally before the start of the heating season, so that it operates efficiently and reliably throughout the colder months. Regular servicing includes a comprehensive system inspection, which involves cleaning components, checking for wear and tear, and ensuring all parts are functioning correctly. This proactive approach helps identify and address potential issues before they become major problems and helps the heater run safely.
Key benefits of routine heater services include:
- Enhanced efficiency: Keeps the system running at peak performance, reducing energy bills
- Extended lifespan: Helps prevent premature wear and tear, extending the life of the heater
- Improved safety: Identifies and addresses potential safety hazards
- Fewer repairs: Reduces the likelihood of unexpected breakdowns and costly repairs
- Better air quality: Ensures clean filters and components, improving indoor air quality
- Consistent comfort: Maintains reliable and even heating throughout your home

How Do I Know When My Heater Needs Service?
When you notice any signs of trouble, addressing them promptly is important to avoid more serious problems and costly repairs. Even heater issues that appear to be minor – such as malfunctioning thermostats or unusual noises – can quickly snowball into major repairs if left unaddressed.
Nine signs you need to schedule a heater service include:
- Uneven or inadequate heating in different rooms
- Unusual sounds like banging, squealing, or clanking
- Your heater turns on and off more frequently than usual
- A sudden rise in heating costs
- Dusty or musty smells, increased dust, or other signs of poor indoor air quality
- Weak or inconsistent airflow from vents
- Problems with the pilot light or burner flame
- Your thermostat is not responding correctly or showing inaccurate readings
- Your heater fails to start or shuts down unexpectedly
