7 Easy DIY Furnace Maintenance Tips

1. Change or Clean the Furnace Filter

This is the biggest secret to a long and healthy furnace life. Your air filter captures dust, dirt, and debris to keep your home’s air clean and protect the furnace's inner components. When filters clog up, your furnace works overtime, wasting energy and wearing out faster.

How often should you do it?

You should clean the filters every 1-3 months during heating season. If you have pets, allergies, or lots of dust, do it more frequently.

If you find filters heavily clogged while cleaning, contact a professional team to get them replaced with brand new filters.

2. Keep the Area Around Your Furnace Clean

The area around your furnace should be clear of dust, debris, and flammable materials. Vacuum the floor and clean surfaces to prevent dust buildup, which can affect performance.

3. Clean Vents and Registers

Clogged or dirty vents can block airflow, resulting in uneven heating.

• Make sure all vents and registers in your home are unobstructed.
• Wipe them down or vacuum as needed.
• Periodically, consider having your air ducts professionally cleaned. If you notice excess dust, allergies, or uneven heating, cleaning becomes even more important.

4. Test the Thermostat

Is your home colder or warmer than you set it? Your thermostat may not be functioning correctly.

• Check if the setting matches the current room temperature.
• Try replacing the batteries.
• Upgrade your furnace settings to a programmable thermostat to save energy. This can actually pay for itself over time.

5. Check and Maintain Your Furnace Humidifier 

Low humidity during winter is uncomfortable and can stress your heating system.

• Clean the humidifier pad or drum as directed in your furnace manual.
• Set your home’s humidity between 30-40% for comfort and furnace efficiency.

6. Clean Up the Furnace’s Interior

Dust and debris can collect inside your furnace over time. 

• Carefully vacuum around the blower compartment using a soft brush attachment.
• Then wipe fan blades with a damp cloth.
• Avoid touching wiring or the burner, and leave deeper cleaning to professionals.

Before starting the cleaning procedure, always turn off the power and gas.

7. Don’t Ignore the Warning Signs

If your furnace is showing signs like odd noises (rattling, banging, squealing), frequent cycling, or a yellow burner flame, it means something’s wrong.

• Regularly check for any water leaks, dust layers, or strange odors.
• If you spot any of these, schedule a professional inspection. Small issues often turn into expensive repairs when ignored.

8. Take Care of Carbon Monoxide and Gas Leaks

• Install a carbon monoxide detector near your furnace and in sleeping areas.
• Test batteries monthly.
• If you ever suspect a gas leak (like a rotten egg smell), leave your home immediately and call emergency services.

9. Check the Condensate Drain

Make sure that the condensate drain is clear to maintain humidity levels and prevent water damage. A blocked drain might result in system shutdowns and potential water damage at any time.

10. Schedule Yearly Professional Maintenance

Some tasks are best left to the pros. An annual inspection and tune-up by a licensed HVAC company, like Ace Plumbing, is important so that you can make sure 

• All critical components, like the heat exchanger, burners, and electrical connections, are safe.
• Your system is running at peak efficiency.
• Hidden problems are fixed, and cannot become emergencies later.
