5 Things You Should Do For Your Furnace During Subzero Cold Snaps

You're in the heart of winter and your furnace is your shield against the icy onslaught. But is it ready for the fight? If it's struggling, you're feeling it. Don't let the chill invade your cozy haven.

Let's dive into 5 things you need to do for your furnace during these subzero battles. Not only will you boost your home's warmth, but you'll also save on potential repair costs. 

Key Takeaways 

  • Check and replace furnace filters regularly, especially during winter months, to ensure the furnace works efficiently and to avoid higher energy bills. 
  • Schedule a professional furnace inspection once a year to spot any issues early, prevent major breakdowns, and ensure the furnace can handle extremely cold weather. 
  • Keep the exhaust pipes clear of snow, ice, or debris to prevent dangerous carbon monoxide buildup and maintain a safer and more efficient furnace. 
  • Consider scheduling a professional tune-up to have all components checked, potential issues fixed, and to keep the furnace running efficiently and safeguard your home from dangerous situations. 

1. Ensuring Proper Insulation 

Proper insulation is crucial during the winter months to ensure the efficient functioning of your furnace. Without adequate insulation, your home becomes more susceptible to heat loss, resulting in your furnace working harder to maintain a comfortable temperature. This increased workload not only puts a strain on the system but also leads to higher energy consumption and utility bills. 

By properly insulating your home, you can create a barrier that prevents heat from escaping, allowing your furnace to operate at its optimal level. Insulation reduces heat transfer through walls, ceilings, and floors, keeping the warm air generated by your furnace inside and preventing cold drafts from entering. This not only improves the overall efficiency of your heating system but also enhances the comfort and coziness of your living space during the chilly winter months.

Don't scrimp on this. If you ignore it, you're risking a major furnace breakdown in the middle of a subzero snap. And trust us, that's not a situation you want to find yourself in. A regular check-up might cost you a bit, but it's a small price to pay for the comfort and peace of mind it brings. 

3. Changing Your Furnace Filters 

Continuing with your furnace maintenance, it's crucial to regularly change the filters, especially during the winter months. When temperatures plummet, your furnace works overtime to keep your home warm, and a dirty filter can cause it to work even harder. This not only increases your energy bills, but it can also shorten the lifespan of your furnace.   

Changing your furnace filters is an easy task. Simply purchase the correct size, turn off your furnace, remove the old filter, and replace it with the new one. Check your filter monthly and change it at least every three months during the heating season. This simple act can keep your furnace running efficiently and save you from costly repairs.
