Stay Warm in Saskatoon: Furnace Maintenance Tips for Fall and Winter

It happens every year. Spring, Summer… Roadwork, and the inevitable colder months of the Canadian prairies.

Your furnace is truly the core of your home, and regular furnace maintenance not only prolongs the life of your heating system but also enhances its efficiency and reduces energy costs. Here are some essential tips to help you prepare your furnace for the colder months.

1. Schedule Your Yearly Inspection

Before the heating season kicks into full gear, it’s good to have your furnace inspected by a professional HVAC technician. A thorough inspection can:

• Identify and address potential issues before they become costly repairs.
• Ensure the furnace is operating safely, especially for gas or oil systems where carbon monoxide leaks can be a concern.
• Optimize efficiency, reducing your energy bills.

2. Replace Air Filters Regularly

Air filters are among the most critical components of your furnace system. They trap dust, debris, and allergens, so that the air circulating through your home is clean. Over time, however, these filters can become clogged, reducing airflow and forcing your furnace to work harder. Here’s what you can do: 

• Check your filter monthly and replace it every 1-3 months, depending on usage and filter type.
• Consider high-efficiency filters that capture smaller particles, especially if you have allergies or pets.
• Pro Tip: Talk to your Razor Heating tech to learn more about our filter program, and find out how you can get your replacement filter delivered right to your door. 

3. Clean the Furnace and Surrounding Area

Dust and debris can accumulate in and around your furnace, potentially causing it to overheat or function inefficiently.

Keep the area around the furnace free from clutter for maximum airflow. You can also clean it by using a vacuum to remove dust from the exterior and accessible interior components (Don’t forget to turn the furnace off while doing this!).

4. Test Your Thermostat

A properly functioning thermostat ensures your furnace runs efficiently, maintaining a comfortable indoor temperature without wasting energy.

Test the thermostat by setting it to a higher temperature and ensuring the furnace responds promptly.If you’re using an older thermostat, consider upgrading to a programmable or smart thermostat for better control and energy savings. We’re always happy to chat with you about the best options for your home and needs. 

5. Inspect and Seal Ductwork

Leaky ducts can result in significant heat loss, so your furnace has to work harder to maintain those comfortable temperatures. A couple of things you can do: 

• Look for visible gaps, holes, or disconnected sections in your ductwork.
• Use metal tape or mastic sealant to seal any leaks. Don’t use duct tape – it  deteriorates over time.
• Consider insulating ducts in unheated spaces like basements or attics to prevent heat loss.

6. Check the Pilot Light or Ignition System

If your furnace has a pilot light, it should burn blue. A yellow or flickering flame could indicate a problem, such as dirt buildup or a carbon monoxide issue. For electronic ignition systems, consult your furnace manual for troubleshooting tips or call us if it fails to ignite.

7.  Inspect the Heat Exchanger

The heat exchanger is a vital component that transfers heat from the furnace to the air. Cracks or damage can lead to carbon monoxide leaks, which are hazardous.

Pro Tip: Install a carbon monoxide detector near your furnace for added safety.

8. Monitor Energy Bills

An unexpected spike in your energy bill could signal that your furnace is working inefficiently. Keeping an eye on your bill will let you catch any major changes more quickly. 

9. Maintain Proper Ventilation

Blocked vents can hinder airflow and reduce your furnace’s efficiency. Ensure all supply and return vents are open and unobstructed, and be sure to clean vents and registers regularly to remove dust buildup.

10. Check the Exhaust System

The exhaust flue removes harmful gases produced during combustion. Any blockages can pose serious safety risks. A few things you can do:

• Inspect the flue for obstructions like bird nests, leaves, or snow.
• Ensure all connections are secure and free of rust or damage.

11. Prepare for Power Outages

Winter storms can lead to power outages, leaving your furnace inoperable. Be prepared by:

• Installing a backup generator to keep your furnace running.
• Making sure you have lots of blankets and warm clothes available, just in case.

12. Consider Upgrading Your Furnace

If your furnace is more than 15-20 years old or frequently needs repairs, it may be time to invest in a new, energy-efficient model. Modern furnaces have improved energy efficiency, potentially reducing heating costs. Feel free to reach out and talk to us if you have questions about when to upgrade, and what systems would work best for your home and your budget. 

13. Winterize Your Home

A well-insulated and sealed home reduces the workload on your furnace. Some of the things you can do: 

• Install weatherstripping around doors and windows.
• Use heavy curtains to reduce heat loss through windows.
• Seal gaps and cracks in walls, floors, and ceilings.

A Couple of Bonus Tips for Even Better Energy Efficiency

• Lower your thermostat by a few degrees when you’re asleep or away from home. If you have a smart thermostat, you can often schedule these to change automatically.
• Use ceiling fans to circulate warm air (set them to rotate clockwise at a low speed).
• Schedule regular maintenance to ensure your furnace operates at peak performance.

Proper furnace maintenance is essential for a warm, comfortable, and energy-efficient home during Saskatchewan’s fall and winter months. Don’t wait for the first snowstorm to start thinking about your furnace— start in October!
