What Is Emergency Heat?
Every heat pump thermostat has an "Emergency Heat" or "Em Heat" setting, and most homeowners in Asheville and Western North Carolina have no idea when to use it — or what it actually does. Emergency heat bypasses your heat pump entirely and relies solely on your backup heating system, which is typically electric resistance heat strips built into your air handler. This backup system is less efficient (and more expensive to operate) than your heat pump, which is why it's labeled "emergency" — it's meant for situations where the heat pump itself cannot operate.
When to Switch to Emergency Heat
Use emergency heat only when your heat pump has physically failed and cannot run — for example, if the outdoor unit is damaged, the compressor has failed, or the unit is completely iced over and the defrost cycle isn't working. Emergency heat keeps your home warm while you wait for repair. Do NOT switch to emergency heat just because it's cold outside. Modern heat pumps, especially cold climate models, are designed to heat efficiently even in sub-freezing temperatures. Running on emergency heat when the heat pump is functional wastes enormous amounts of electricity.
The Cost of Running Emergency Heat
Electric resistance heat is roughly three times more expensive to operate than a heat pump per unit of heating. If your heat pump has a COP (coefficient of performance) of 3.0, it produces three units of heat for every unit of electricity consumed. Emergency heat strips have a COP of 1.0 — they convert electricity to heat at a 1:1 ratio. Running emergency heat for even a few days during a WNC winter can add $100 to $300 to your electric bill. This is why prompt heat pump repair is critical.

HVAC Challenges in Mills River
Mills River's rural properties often sit on larger lots with longer refrigerant line runs between indoor and outdoor units — requiring careful system design to maintain efficiency. Many homes use well water and septic systems, which means HVAC condensate drainage needs specific attention. The area's mix of farmland and forest creates heavy pollen loads in spring that clog filters quickly.
Seasonal Tip for Mills River Homeowners
Mills River's open valley floor means summer temperatures can run 3–5°F warmer than tree-covered areas at the same elevation. If you're in an exposed location, consider adding shade structures near your outdoor condenser unit — it can improve AC efficiency by up to 10%.
