Heating Systems in Wake County, NC

What Most Wake County Homes Have

The large majority of Wake County homes heat with heat pumps. Gas furnaces exist, particularly in older construction and some neighborhoods where natural gas lines were installed in the 1970s–1990s. Resistance electric heat appears in older homes and some condos. Propane systems appear in rural areas without gas line access.

If you are not sure what your system is: a heat pump has an outdoor unit that runs in both summer and winter. A gas furnace has a flue pipe exiting the house (typically through the roof or wall). Electric resistance systems have no outdoor unit and often a simple thermostat with limited programmability.

Heat Pump Heating Mode

Heat pumps extract heat from outdoor air and move it inside. This works efficiently until outdoor temperatures fall below a system-specific balance point — typically somewhere between 30–40°F depending on the equipment. Below that point, auxiliary electric resistance strips engage.

One common misunderstanding: seeing the auxiliary heat light on the thermostat does not mean something is wrong. It means the temperature is low enough that supplemental heat is running. The issue is if auxiliary heat runs continuously at moderate temperatures (above 45°F), which can indicate a refrigerant charge problem or reversing valve fault.

What Good Heating Service Looks Like

A thorough heating service call on a heat pump includes:

• Refrigerant pressure check at heating conditions
• Reversing valve confirmation
• Defrost cycle test
• Auxiliary strip test with measured amperage
• Discharge air temperature at the register
