- Why it matters: A clogged or dirty air filter reduces airflow, causing the furnace to work harder, which can lead to higher energy bills and potentially damage the system.
- How to do it: (if you’re going to do this yourself)
- Turn off the furnace and remove the filter.
- If you’re uncertain where the filter is on your furnace, start by following the cold air return to your furnace. Most filters are located close to the base of where the cold air return connects to your furnace.
- Inspect the filter for dust and debris. If it’s clogged, replace it with a new one of the correct size.
- Replace the air filter at least once every 1-3 months during the winter season, depending on your usage and the type of filter.
- When replacing your air filter, it’s important to replace the new filter in the right direction. Along the edge it will show an arrow that aligns with how the air flows through your furnace.

Do you know the MERV rating of your furnace filter?
Furnace filters are rated by a system called MERV (Minimum Efficiency Reporting Value), which measures how effectively a filter captures particles. The higher the MERV rating, the smaller the particles the filter can trap, but it also means the filter is denser, which could potentially reduce airflow if not properly matched to your system. Resource: https://www.epa.gov/indoor-air-quality-iaq/what-merv-rating.
MERV Rating Breakdown:
MERV 1-4:
These are basic filters. They catch large particles like dust, dirt, and pollen. They’re typically found in cheaper fiberglass filters.
-
- Particle Size: 10 microns and larger.
- Common Use: Basic filtration for home environments where air quality is not a major concern.
MERV 5-8:
These are more efficient and can trap smaller particles like pet dander, mold spores, and dust mites.
-
- Particle Size: 3-10 microns.
- Common Use: Used in homes, apartments, or offices where better filtration is desired but not at the highest level.
MERV 9-12:
These filters are highly effective at trapping even smaller particles like pet dander, fine dust, and smoke.
MERV 13-16:
These are hospital-grade filters that capture very fine particles, including bacteria, some viruses, and fine dust.
MERV 17-20 (HEPA filters):
These are the most efficient filters, often used in clean rooms, labs, and hospitals. They can capture nearly all particles down to 0.3 microns.
2. It’s always advised to test the Furnace Before Cold Weather Hits
Why it matters
Testing your furnace before you really need it can prevent unpleasant surprises during the first cold snap.
How to do it:
- Turn the thermostat to the “heat” setting and raise the temperature a few degrees above room temperature.
- Ensure that the furnace starts up and runs smoothly.
- Check that hot air is coming from the vents after a minute or two
3. Inspecting and Cleaning the Furnace Vents
Why it matters
Blocked vents can hinder proper airflow, leading to inefficient heating and potential furnace overheating.
How to do it:
- Turn the thermostat to the “heat” setting and raise the temperature a few degrees above room temperature.
- Ensure that the furnace starts up and runs smoothly.
- Check that hot air is coming from the vents after a minute or two
4. Examine the Thermostat
Why it matters
A malfunctioning thermostat can cause your furnace to cycle erratically, resulting in inconsistent temperatures and higher energy usage.
How to do it:
- Check if the thermostat is working properly by setting it to a temperature above room temperature and verifying the furnace responds.
- If you have an older manual thermostat consider upgrading to a programmable or smart thermostat for better control over heating cycles. Talk to your professional as they can recommend the thermostat that will work best with your system.
- Make sure the thermostat is installed away from heat sources like lamps or direct sunlight
5. Inspect the Flue and Venting System
Why it matters
A blocked flue or vent can cause dangerous carbon monoxide buildup.
How to do it:
- Ensure the venting system is free from debris nests or obstructions.
- Look for signs of wear or rust in the flue.
- If your furnace is venting through a chimney ensure the chimney is clear of blockages and buildup.
6. Are you hearing unusual noises or smelling Odors from your Furnace?
Why it matters
Unusual sounds or smells can indicate problems with the furnace, such as worn parts, gas leaks, or mold in the system.
How to do it:
- Listen for banging popping or rattling sounds which may indicate loose components or airflow issues.
- If you smell a musty odor or a gas-like smell shut off the furnace and call a professional immediately.
7. Ensure Proper Airflow and Insulation
Why it matters
Proper airflow and insulation help your furnace work efficiently and ensure even heating throughout your home.
How to do it:
- Check that your home’s insulation is adequate especially in attics basements and crawl spaces.
- Ensure that ducts are properly sealed and insulated to prevent heat loss.
- Consider using draft stoppers on doors and windows to improve the overall efficiency of your heating system.
We encourage you to schedule a Professional Inspection
Why it matters
Even with regular maintenance, it’s important to have a professional HVAC technician inspect and service your furnace annually to ensure it’s in top condition.
How to do it:
- A technician will typically clean and lubricate the furnace check for gas leaks ensure proper burner function inspect the heat exchanger and calibrate the thermostat.
- Regular maintenance extends the life of your furnace and can help avoid costly repairs.
A profession will…
A profession will inspect the Furnace Blower Motor and Components
Why it matters: The blower motor circulates warm air through the ductwork. If it’s dirty or malfunctioning, it can reduce heating efficiency. Resource link: OSHA Guide on Furnace Safety
A professional will check the Gas Line and Pilot Light (for Gas Furnaces)
Why it matters: A malfunctioning gas line or pilot light can cause your furnace to stop working or even be dangerous. Resource link: NFPA Guidelines on Gas Furnace Safety
A professional will inspect the Furnace’s Burner Assembly (for Gas Furnaces)
Why it matters: Dirty burners can affect the furnace’s performance, causing uneven heating or inefficient combustion.
Consider Upgrading to a More Efficient Model
Why it matters
If your furnace is old and inefficient, it may be time to upgrade to a more energy-efficient model to save on heating costs in the long run.
How to do it:
- Consult with a professional HVAC technician to see if upgrading to a new furnace makes sense for your home and budget.
- A professional will look at the overall square footage fuel source how well the home or business is insulated and how the furnace will be used to determine the right equipment for your home or office.
Winter Furnace Maintenance Tips – Quick winter tips for homeowners
-
Keep vents clear of obstructions.
-
Schedule a professional inspection before winter hits.
-
Test your furnace early in the season to catch issues.
-
Consider upgrading to a more efficient furnace if your current system is outdated. You may find that a new furnace will cost less to operate and maintain resulting in an overall significant savings.
