How Winter Weather in Boone Can Affect Your HVAC System — And What You Can Do About It
Winter in the High Country is beautiful — crisp mornings, occasional snow flurries, and that cozy mountain feel many of us love this time of year. But Boone’s winter weather also creates unique challenges for your home’s HVAC system. With average highs in the 40s and lows frequently dipping near or below freezing, your heating system is working harder than you might realize. At Edmisten Heating & Cooling, we’re here to help you understand how winter conditions affect your HVAC equipment — and how proactive care can keep your home comfortable all season long.
1. Freeze-Thaw Cycles Put Extra Strain on HVAC Components
Boone often experiences temperatures that swing above and below freezing throughout the day. These daily freeze-thaw cycles can stress outdoor heat pump components, refrigerant lines, and even the protective coatings on your system. Over time, this stress can lead to cracks, corrosion, or premature wear.
What to do:
- Keep outdoor units clear of ice and snow buildup.
- Schedule a winter tune-up to catch small problems before they become costly.
2. Your Heating System Is Running More Than You Think
Even on milder winter days, the average high stays in the 40s. That means your furnace or heat pump is often needed to keep indoor temperatures comfortable — even when it feels warm outside. If your system isn’t maintained, this additional runtime can expose worn components and inefficient operation.
Pro tip:
Change your air filter regularly — every 1–3 months — to maintain airflow and efficiency during heavy use.
3. Low Outdoor Temperatures Can Reduce Heat Pump Efficiency
Heat pumps are excellent for year-round comfort, but Boone’s colder winter temperatures can reduce their efficiency. As the outdoor air gets colder, the heat pump must work harder to extract heat from the air — and efficiency drops.
Solution:
Consider a dual-fuel setup (heat pump with a furnace backup) or a high-efficiency heat pump designed for colder climates.
4. Watch for Signs Your System Needs Attention
A little awareness can go a long way. During winter ask yourself:
- Are some rooms colder than others?
- Do you notice higher heating bills compared to last winter?
- Is the system making strange noises?
If so, it might be time for a professional inspection.
5. Don’t Wait for a Breakdown — Be Proactive
Nothing’s worse than a heating system failure on the coldest night of the year. Preventive maintenance — like a winter HVAC inspection — helps ensure:
- Your system runs efficiently
- Wear-and-tear issues are caught early
- You stay warm and worry-free all season
Our Boone technicians know how mountain weather impacts HVAC systems and can tailor maintenance or repairs to your home’s needs.
