In Boone, NC, fall can feel like it flips to winter overnight. One week you’re enjoying crisp mountain hikes; the next, frost is on the grass, and you’re firing up the heat for the first time in months. A few simple fall checks now can help you avoid cold-weather breakdowns, high utility bills, and costly repairs later. Here are five essential heating system steps to take before the High Country winter settles in.

1. Schedule a Professional Heating Tune-Up

Your furnace, heat pump, or boiler has been sitting idle through summer. A seasonal tune-up ensures everything is running safely and efficiently before it’s pushed into full-time service. Our Mountaineer Heating & Cooling technicians check and clean burners, inspect electrical components, lubricate moving parts, and verify system performance. Catching small issues now can prevent an emergency call in the middle of a snowstorm.

2. Replace or Clean Your Air Filter

A clogged air filter can make your heating system work harder, leading to higher bills and unnecessary wear. In Boone’s mountain climate, where we keep windows open in early fall, filters can collect more dust and pollen than you might expect. Check your filter monthly and replace it every 1–3 months—or more often if you have pets or allergies.

3. Test Your Thermostat and Settings

Switch your thermostat from cooling to heating mode and raise the temperature a few degrees. Make sure the system kicks on promptly and produces warm air. This is also a good time to:

Change thermostat batteries
Verify programmed schedules match your fall and winter routine
Consider upgrading to a smart thermostat for better comfort control and efficiency

4. Inspect and Clear Vents, Registers, and Returns

Blocked airflow is one of the most common heating inefficiencies. Walk through your home and ensure all supply vents and return air registers are open, unblocked by furniture, and free of dust buildup. Restricted airflow can make some rooms colder, strain your system, and drive up your heating costs.

5. Check for Air Leaks Around Windows and Doors

Your heating system works best in a well-sealed home. Cold drafts around doors and windows force your unit to run longer, wasting energy and money. Adding weatherstripping or caulking problem areas is an inexpensive fix that makes a big difference in comfort and utility bills.

Why These Checks Matter in Boone’s Climate

Our High Country winters are long, cold, and unpredictable. Skipping fall maintenance can mean waking up to a frigid house during a sudden temperature drop—or facing a repair backlog during the first cold snap of the season. By getting your system ready now, you’ll have peace of mind knowing your home will stay warm no matter what the mountain weather throws at you.
