When the leaves start to turn and the evenings get cooler, there’s nothing better than stepping into a warm, cozy home. But here’s the thing—your furnace doesn’t magically keep you comfortable. Just like a car, it needs regular attention to run its best. If you wait until the first frosty night to flip the switch and something goes wrong, you could be left shivering while waiting for emergency service.
That’s why a little preparation now can save you from headaches later. Here are seven things every homeowner should do to get their furnace ready before the cold weather really sets in.
1. Schedule a Professional Tune-Up
This one can’t be overstated. Our licensed HVAC technicians don’t just give your system a quick glance—they’ll clean critical components, check for worn-out parts, and make sure everything is running efficiently. It’s like a wellness check for your furnace. Skipping this step might save you a little upfront, but it could cost you much more if a breakdown happens on the coldest night of the year.
2. Change Your Air Filter
It might sound basic, but this is the most important step you can take. A clogged filter makes your furnace work harder, shortens its lifespan, and drives up your energy bills. Plus, it impacts your air quality—something you’ll notice once your home is sealed tight for the season. A fresh filter every 1–3 months is a small effort that makes a big difference.
3. Clear the Area Around Your Furnace
Think of your furnace like the heart of your home—it needs room to breathe. Boxes, storage bins, or laundry piled too close can restrict airflow and even become a fire hazard. Take a quick look around your utility space and clear at least 3 feet of space around the unit. It not only improves safety but also makes it easier for technicians to do their job when it’s time for service.
4. Test Your Thermostat
Your thermostat is basically the “remote control” for your comfort. Switch it over to heat mode and set the temperature a few degrees higher than the current room temperature. You should hear the furnace kick on within a minute or two. If it doesn’t, or if it takes longer than it should, that’s a red flag worth addressing before you’re relying on it daily.

6. Check Your Carbon Monoxide Detector
Furnaces burn fuel to create heat, and while modern systems are built with safety in mind, carbon monoxide leaks can still happen. Testing your detector and replacing the batteries gives you peace of mind. If you don’t already have one near your furnace and sleeping areas, this is a good time to add them. Safety first, always. And if you need a new CO monitor, we can install one for you during your tune-up visit.
7. Seal Up Drafts Around the House
Even the best furnace struggles if your warm air is escaping. Check around windows and doors for drafts and use weatherstripping or caulking to seal them. Not only will your home stay warmer, but your furnace won’t have to work as hard—meaning lower utility bills and less wear and tear.
8. Listen and Pay Attention
Finally, trust your instincts. When you first fire up your furnace, pay attention to how it sounds and smells. A slight burning odor is normal the first time (dust burning off after sitting unused), but it should go away quickly. If you hear clanking, banging, or smell anything unusual beyond that first hour, it’s best to call in our team right away.
