The winter months are upon us, and as temperatures drop, our reliance on heating systems, particularly furnaces, intensifies. The last thing anyone wants is to face a malfunctioning HVAC system during extremely cold weather. To ensure your home stays warm and cozy, it’s crucial to take proactive steps to keep your furnace running smoothly throughout the heating season. Here’s a comprehensive list of cold weather furnace tips that will help you maintain optimal performance despite the extreme cold.


1. Schedule Furnace Maintenance

Start the winter season on the right foot by scheduling a professional furnace maintenance service. During routine maintenance, a certified technician inspects and tunes up your furnace, identifying potential performance or safety issues before they escalate. Regular furnace inspections and tune ups not only help you maintain an efficient furnace during extreme cold weather but also extend the lifespan of your heating system.


2. Keep the Air Filter Clean

A simple yet effective maintenance task is to make sure you have a clean air filter installed. A dirty or clogged filter restricts airflow, causing the furnace to work harder and consume more energy to push warm air through the system.

Aim to replace the furnace filter every 1-3 months, depending on the type of filter and the level of usage. Doing so will help your heating system keep your home warm and improve indoor air quality.


3. Check and Clean Vents and Ducts

Inspect vents and ducts for any obstructions or blockages. Clear away dust, debris, or any items that may be impeding the airflow. Proper ventilation ensures that the hot air generated by the furnace circulates effectively throughout your home.


4. Monitor the Thermostat’s Temperature Setting

Optimize your furnace’s efficiency by setting your thermostat at reasonable indoor temperatures. Typically, outdoor and indoor temperatures should only be about 10 to 15 degrees apart, but during extremely cold weather, this isn’t comfortable. Make minor increases as you work to find a comfortable temperature and conserve energy.

Consider investing in a programmable thermostat that allows you to automatically adjust the temperature based on your schedule. Lowering the temperature and keeping a consistent setting for longer periods when you’re away or asleep can significantly reduce energy consumption and reduce wear and tear on the HVAC system.


5. Seal Air Leaks

Prevent heat loss during extremely cold weather by identifying and sealing air leaks in your home. Check for gaps around windows, doors, and other potential entry points for cold air. Weather-stripping and caulking are cost-effective solutions to keep the warmth in and the freezing cold out.


6. Insulate Your Home

Proper insulation is key to maintaining a comfortable indoor temperature. Insulate your attic, walls, and basement to prevent heat from escaping. This not only eases the burden on your furnace but also contributes to energy savings. Insulation also helps prevent frozen pipes, which are a risk during extreme cold weather.


7. Clear the Area Around Your Furnace

Ensure that the space around your gas furnace is clutter-free. Remove any items stored nearby and create a clear path for proper ventilation. This not only enhances safety but also facilitates easy access for maintenance and repairs.


8. Monitor Carbon Monoxide Levels

Carbon monoxide is a colorless and odorless gas that can be emitted by a malfunctioning furnace, particularly one with a cracked heat exchanger. Install carbon monoxide detectors near bedrooms and other key areas in your home. Regularly check the detectors to ensure they are in good working condition.


9. Keep the Area Around the Outdoor Exhaust Clear

Make sure the furnace exhaust pipe or clue is clear of snow, ice, and debris, which can build up when it is extremely cold outside. A blocked exhaust can lead to improper ventilation and pose a safety risk. Regularly check and clear the area around the exhaust to ensure proper functioning.

Just like air conditioning and heat pump systems have a drain line for condensate, so do condensing furnaces. For homes with condensing high-efficiency furnaces that have a drain line that runs outdoors, make sure ice or snow is not clogging the discharge pipe.


10. Monitor Fuel Levels

If your furnace operates on oil or propane, keep a close eye on fuel levels. Running out of fuel can leave you in the cold and potentially damage your furnace. Schedule fuel deliveries in advance to avoid interruptions in service.


11. Invest in a Humidifier

Winter air tends to be dry, which can affect both your comfort and your furnace’s performance. Consider using a humidifier to add moisture to the air. This not only helps maintain a comfortable indoor environment but also reduces the workload on your furnace.


12. Utilize Ceiling Fans

By running your ceiling fan in a clockwise direction on a low setting, you can create an updraft that redistributes warm air accumulated near the ceiling back down to the living space. This allows you to keep your thermostat set back a few degrees from the normal temperature without sacrificing comfort.

As a result, your furnace doesn’t need to work as hard to maintain the desired at-home temperature. This reduces strain on the furnace to help prevent breakdowns and conserves energy, potentially lowering your heating bills.
