A heat pump failing in Morgan County is almost never a weather story. 58 severe weather events were recorded in Morgan County, Tennessee between 2015 and 2024. At that rate, severe weather is an event here, not a constant pressure, and a contractor diagnosing a broken heat pump will look past it quickly. What they are actually chasing is how the refrigerant circuit has held up, whether the reversing valve has worn unevenly, and how well the original install was done. Those are the factors that decide the repair scope and the bill.
Ductwork in a house built for an earlier generation of heating and cooling carries the record of every repair, retrofit, and workaround that came before the current heat pump. Half the homes in Morgan County, Tennessee were built in 1985 or earlier (2020-2024 ACS 5-year). When a contractor opens a heat pump that is not performing, the refrigerant circuit and the electrical connections are often in serviceable shape. What sends the job in a different direction is what they find in the ducts: collapsed flex sections, bypassed dampers, or joints that have been leaking conditioned air long enough to hide the real cause of the comfort complaint. Parts for the unit are one question. Whether the distribution system is actually delivering what the unit produces is another, and in stock this age it is the one that changes the scope of the repair.
The Parts of a Heat Pump a Contractor Checks During Repair
The outdoor unit sits on a pad beside the house and holds the compressor, which is where most repair calls begin. When the compressor fails, the system runs but moves no heat. The unit also contains the outdoor coil and a fan that pulls air across it; a bent or blocked coil and a failing fan motor are both common finds during a service call.
Inside the house, the air handler holds the indoor coil and the blower motor that pushes conditioned air into the living space. The refrigerant lines connect the two units, and the reversing valve inside the system is what lets a heat pump switch between heating and cooling. A contractor checks the expansion valve and the electrical controls in both cabinets as well.
The drawing shows a typical layout, and a licensed contractor determines which components apply to your specific system and home.

Severe Weather Events in Morgan County
Weather puts a measurable load on heat pump equipment, and that load is local. How hard the system runs, how often it cycles under stress, and when it tends to fail are all shaped by what the climate here actually does.
