Heating in Franklin comes with unique demands. At 2,113 feet elevation, winters are moderate but still require a reliable heating system. Franklin's location in the Little Tennessee River valley creates a moderate mountain climate, but the distance from major service centers means many homes go longer between HVAC maintenance visits. Macon County's mix of year-round residents and seasonal mountain homeowners creates varied demands — some systems sit idle for months, then must perform immediately. Natural gas availability is limited outside the town core, making propane and heat pump expertise essential. Our heating technicians factor in these Franklin-specific conditions for every repair and installation.
What Is the Heat Pump Defrost Cycle?
If you own a heat pump in Asheville or Western North Carolina, you've probably seen it: on a cold winter morning, your outdoor unit suddenly starts blowing steam, the fan stops, and the system seems to switch into cooling mode briefly. This is the defrost cycle, and it's completely normal. During heating mode, your heat pump extracts warmth from outdoor air by running extremely cold refrigerant through the outdoor coil. When outdoor temperatures drop below about 40 degrees and humidity is present, frost naturally builds up on the coil — and that frost must be melted periodically to maintain heating efficiency.
How Defrost Works
When the control board detects frost buildup (through temperature sensors or a timer), it temporarily reverses the refrigerant flow — essentially running the system in cooling mode for a few minutes to send hot refrigerant through the outdoor coil and melt the ice. During this time, the outdoor fan shuts off to prevent blowing cold air over the coil (which would defeat the purpose), and your system activates auxiliary heat strips or backup heating to prevent cold air from blowing into your home. A normal defrost cycle lasts 2 to 10 minutes and occurs a few times per day in cold weather.
When Defrost Becomes a Problem
If your heat pump defrosts too frequently (every 30 minutes or more), stays in defrost for extended periods, or fails to defrost at all (leaving the outdoor coil covered in thick ice), something is wrong. Common causes include a faulty defrost control board, a stuck reversing valve, a bad defrost thermostat or sensor, low refrigerant charge, or a failed outdoor fan motor. A heat pump caked in ice is losing efficiency rapidly and stressing the compressor.
Quality Comfort Knows Heat Pumps
Heat pumps are the primary heating system for thousands of WNC homes, and understanding the defrost cycle is essential to proper heat pump repair. Our technicians diagnose defrost issues by testing the control board, sensors, reversing valve, and refrigerant charge — not by guessing. If your heat pump seems to be icing up too much or not defrosting properly, call us before the problem causes compressor damage.

Seasonal Tip for Franklin Homeowners
Franklin homeowners with seasonal properties should install smart thermostats with freeze protection alerts. Set a minimum temperature of 55°F when away, and schedule pre-season HVAC checks before you return for the season to avoid unpleasant surprises with a system that's been dormant.
