Preparing Your HVAC System for Snow in the High Country
The High Country doesn't just get snow — it gets serious snow. Beech Mountain averages over 80 inches per year, and even Boone sees significant accumulation. When the snow flies, your HVAC system needs to be ready. Here's how to prepare your heating and cooling system for winter in the mountains.
Schedule Fall Heating Maintenance
Before the first snow, schedule a professional heating system tune-up. A certified technician will inspect your heat pump or furnace, clean critical components, check refrigerant levels, test the defrost cycle (for heat pumps), and identify any worn parts before they fail during a cold snap. In Boone, schedule this by October — our technicians get booked up quickly as winter approaches.
Protect Your Outdoor Heat Pump Unit from Snow
If you have a heat pump, your outdoor unit needs protection from snow and ice:
- Elevate the unit on a pad so it sits above typical snow accumulation
- Clear snow away from all sides after each major storm — at least 2 feet of clearance
- Never cover the unit with a tarp or cover that blocks airflow — this causes moisture buildup and corrosion
- Check for ice buildup on the coil and fan blades; if ice persists, call for service
Seal Drafts and Insulate
Your HVAC system can only do so much if your home is leaking heat. Before winter:
- Check weatherstripping around doors and windows
- Insulate exposed pipes in crawlspaces and attics to prevent freezing
- Seal gaps around plumbing and electrical penetrations
- Consider adding insulation to your attic if it's below R-38
Stock Up on Filters
During heating season, your system runs constantly and filters clog faster. Buy filters in bulk so you always have spares. A clogged filter restricts airflow, reduces efficiency, and can cause your heat pump to freeze up or your furnace to overheat. Check filters monthly during winter and replace them as needed.
Consider a Whole-Home Humidifier
Boone's winters are dry, and heating makes indoor air even drier. Dry air feels colder, so you crank the thermostat higher and pay more in energy bills. A whole-home humidifier adds moisture to the air, making your home feel warmer at lower temperatures and reducing dry skin, static shocks, and cracked woodwork.
