Chilly season is right around the corner: which means cozy blankets, hot cocoa, and cranking up the heat. But before winter sets in and you flip that thermostat on for the first time, it’s worth taking some time to prepare your heating system so it performs at its best when you need it most. A bit of prep now can save you headaches (and money) once winter’s in full swing. Here are a few things to keep in mind:

Book a Tune-Up Book a professional inspection. “Tune-up” means a technician will clean and check for worn parts, make sure all the parts are working properly, and catch small problems before they turn into expensive emergencies. Think of it as an annual wellness visit for your furnace or boiler. Bonus? A freshly tuned system runs more efficiently which means electric bills are lower.

Don’t Forget to Change/Clean Filters (regularly)This one’s easy but often overlooked. Dirty air filters restrict airflow, forcing your system to work harder and use more energy. Not only does this increase utility bills, but it also shortens the lifespan of the unit. Swap yours out every month or two during heating season (or clean it if it’s reusable).

Check for Drafts and Insulation GapsEven the most efficient heating system can’t keep up if your home leaks warm air. Take a walk around your windows, doors, and attic to spot drafts. Weatherstripping, caulking, or added insulation goes a long way to keeping that cozy warm air inside where it belongs.

Test the Thermostat Give your thermostat a quick check before temps dip too low. If you don’t already have a programmable or smart thermostat, now might be the time to invest in one. These devices help regulate temperature efficiently and can cut down on unnecessary heating costs.

Keep Vents and Radiators Clear Make sure nothing’s blocking your vents or radiators. Furniture, curtains, or rugs can trap heat and keep it from spreading through your home. A little rearranging can make your whole place feel warmer.

Pay Attention to Warning Signs Strange noises, funky smells, or uneven heating should never be ignored. Those little quirks could mean your system is struggling and might be on the verge of a bigger problem. Better to call in a pro early.

Safety First If you have a gas furnace, carbon monoxide detectors are a must. Check the batteries and make sure you have one on every floor of your home. It’s an easy step that could save lives.

Have a Backup Plan Sometimes, even with the best prep, heating systems fail. Know who to call for emergency repairs and have backup heat sources like space heaters and extra blankets in case of a temporary outage.

The takeaway? A little bit of prep before winter hits can keep you warm, safe, and stress-free all season long. Your heating system works hard for you—show it a little TLC now, and it’ll return the favor when the temps drop.
