Takes about a minute. No obligation.
A contractor called out for heat pump repair in St. Clair County has to separate what the climate has asked of the system from what time and maintenance have done to it. 90 severe weather events were recorded in St. Clair County, Alabama between 2015 and 2024. That puts this area in a range where severe weather is a real but not dominant variable. The refrigerant lines, the capacitor, the contacts on the contactor: these wear at rates set by run hours and service history more than by storms. A contractor will check for weather-related stress, but in a county at this level of exposure, age and neglect write most of the repair orders.
Half the homes in St. Clair County, Alabama were built in 1998 or earlier (2020-2024 ACS 5-year). A house built around that year has almost certainly been through at least one equipment change since it was first wired, which means what sits in the unit now tells a contractor more than the house does. When a heat pump opens up, the question is whether the components inside it still have a supply chain. Older systems pull from parts pools that narrow over time, and if the replacement part is scarce, the repair scope and the bill both shift before any labor begins.
The Parts of a Heat Pump a Contractor Checks During a Repair
The outdoor unit sits beside the house and holds the compressor and condenser coil. The compressor is the piece a contractor reaches for first when a heat pump stops moving heat altogether. The condenser coil, visible as the metal fins wrapped around the cabinet, is what a contractor examines when the system runs but struggles.
Inside the house, the air handler holds the evaporator coil and the blower. The evaporator coil is a common source of refrigerant leaks and ice buildup. The blower motor is what a contractor tests when airflow through the vents is weak. The reversing valve, which sits in the outdoor unit, is the part a contractor checks when the system heats but will not cool, or the other way around.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines which components apply to the specific setup in your house.

Severe Weather Events in St. Clair County
Weather puts work on heating and cooling equipment. The harder a heat pump has to run to hold indoor conditions, the more wear it accumulates, and in St. Clair County that workload is shaped by local conditions that show up year after year in the record.
