A contractor quoting a heat pump repair in Loudon County has to settle one question before anything else: what actually drove this failure. 79 severe weather events were recorded in Loudon County, Tennessee between 2015 and 2024. That puts this county in the range where severe weather is a real but occasional pressure on equipment, not a constant one. A compressor or reversing valve that has given out here is more likely carrying years of deferred maintenance or an original install that was never quite right than it is bearing the marks of relentless storm load. The contractor checks refrigerant levels, electrical connections, and the condition of the coils before weather enters the conversation.

A heat pump sitting in a house old enough to have already outlasted at least one previous system was installed into infrastructure that has been through that adaptation before. Half the homes in Loudon County, Tennessee were built in 1992 or earlier (2020-2024 ACS 5-year). What a contractor finds once the unit is opened matters more than what year the house was framed: capacitors, reversing valves, and refrigerant fittings on a system of this vintage may draw from a parts supply that has thinned, and that is the variable that decides the scope and the bill. The house is not the bottleneck. Whether the part still ships is.

The Parts of a Heat Pump a Contractor Checks First

The outdoor unit is usually the first thing a contractor reaches for. It houses the compressor, which is the part that does the hardest mechanical work, and the outdoor coil, which sheds or pulls heat depending on the season. When either of those fails, the system stops doing its job in a way that is hard to miss.

Inside the house, the air handler holds the indoor coil and the blower fan, which moves conditioned air through your vents. The reversing valve, which sits within the refrigerant loop and tells the system which direction to run, is a common repair target, as is the expansion valve that controls refrigerant flow between the two coils.

The drawing shows how these pieces relate in a typical layout, and a licensed contractor determines what applies to your specific system.
