Keeping your furnace in good operating order is important not only for your home’s comfort, but also for its safety and efficiency. Regular furnace maintenance can help prevent unexpected malfunctions, lengthen the life of your unit, and potentially reduce your energy expenditures. But the question remains: How often should your furnace be serviced? Let’s get into the details.

Why Annual Furnace Maintenance Matters

Safety: Furnaces provide heat by burning fuel, which can lead to safety issues such as carbon monoxide leaks if not properly maintained.

Efficiency: Regular maintenance ensures that your furnace performs as efficiently as possible, lowering your energy bills and carbon footprint.

Preventing Breakdowns: Catching minor difficulties before they become severe problems will save you money and inconvenience.

Longevity: Well-maintained furnaces can last many years longer than neglected ones, reducing the cost of a replacement.

Annual Servicing: The Golden Rule

The industry standard suggestion is to have your furnace serviced at least once a year. This annual maintenance is best done in early autumn, before the heating season begins. This timing guarantees that any problems are recognised and addressed before you rely significantly on the unit during the colder months.

What Does Furnace Maintenance Include?

Thorough Inspection:

• Heat Exchanger: Checked for cracks or signs of wear, as these can lead to dangerous carbon monoxide leaks.
• Burners: Inspected and cleaned to ensure efficient operation.
• Fan Motor and Blower Wheel: Checked for proper operation and alignment.

Cleaning

• Internal Components: Including burners, ignition systems, and the blower wheel, are cleaned to prevent dirt buildup that can impede performance.
• Air Filters: Replaced or cleaned to ensure good airflow.

Lubrication:

• Moving Parts: Like the blower motor and fan bearings, are lubricated to reduce friction and wear.

Safety Controls Check:

• Thermostat Calibration: Ensuring accurate temperature control.
• Safety Controls and Switches: Tested to ensure they are operating correctly.

Ventilation System:

• Flue System: Checked for obstructions or leaks that could introduce harmful gases into the home.

Efficiency Check:

• Overall Efficiency: Evaluated to ensure the furnace is operating at peak performance.

DIY Furnace Maintenance Tips

While professional servicing is recommended at least once a year, here are some furnace DIY maintenance tips to keep your furnace in top shape:

Change the Air Filter

• Frequency: Every 1-3 months, depending on usage and type of filter.
• Benefit: Improves airflow and efficiency, reduces strain on the furnace.

Keep the Area Around the Furnace Clean

• Regular Cleaning: Ensure the area around the furnace is free from debris, dust, and other obstructions.
• Benefit: Prevents dust from entering the system and reduces fire hazards.

Inspect and Clean Air Vents

• Check Vents: Regularly inspect and vacuum indoor air vents.
• Benefit: Improves airflow and heating efficiency.

Listen for Unusual Noises

• Identifying Issues: Pay attention to any strange sounds coming from the furnace, as these can be early indicators of problems.
• Benefit: Early detection of potential issues before they become serious.

Monitor the Thermostat

• Check Functionality: Ensure the thermostat is working correctly and batteries are replaced if needed.
• Benefit: Maintains consistent temperature and ensures efficient furnace operation.

Inspect the Furnace Flame

• Flame Color: The flame should be blue with a small yellow tip. A predominantly yellow, orange, or flickering flame can indicate a problem.
• Benefit: Indicates efficient burner operation.

When to Call a Professional

Despite regular DIY maintenance, some situations require professional attention, such as:

• Odd Noises: Rattling, banging, or whining noises.
• Frequent Cycling: The furnace turns on and off more frequently than usual.
• Carbon Monoxide Detector Alarms: Indicates potential leaks and requires immediate professional intervention.
