These factors accelerate wear on motors, sensors, ignition controls, and refrigerant lines. HEP’s heat repair services are crafted to combat the specific challenges caused by Erwin’s fluctuating climate, helping homeowners avoid emergency breakdowns and excessive utility bills.

Temperature Extremes That Push Equipment to the Limit

The average January low in Unicoi County dips near 25°F, while July highs frequently touch 87°F. This 60-plus degree swing requires HVAC systems that switch seamlessly between heating and cooling modes. Heat pumps must operate in defrost cycles, furnaces must ignite reliably, and air conditioners must expel moisture efficiently. HEP technicians have extensive training on how these temperature swings affect thermal expansion, refrigerant pressures, and electronic controls so they can calibrate and repair systems for optimal year-round performance.

Common Heating Systems in Erwin Homes

Gas Furnaces

Natural gas furnaces remain a popular choice for their strong heat output. A modern condensing furnace can reach up to 98% AFUE, but only if the burners, heat exchanger, and venting remain free of dirt and corrosion—issues HEP addresses during repair visits.

Heat Pumps

Thanks to their ability to provide both heating and cooling, heat pumps are increasingly common. When reversing valves malfunction or defrost sensors fail, HEP’s EPA-certified technicians restore proper operation so owners retain efficient comfort in every season.

Dual-Fuel Hybrid Systems

A combination of heat pump and gas furnace offers efficiency and power. However, two heat sources also double the number of potential failure points. HEP’s diagnostic process pinpoints whether the compressor, furnace burner, or system controls are at fault.

Electric Resistance Heaters

Townhouses and smaller cabins sometimes rely on electric baseboard or in-duct resistance heat. Tripped limit switches, failed sequencers, and worn heating elements can all lead to cold rooms—issues HEP resolves with OEM-grade replacements.
