Takes about a minute. No obligation.
A contractor called out to repair a heat pump in Shelby County has to work out what actually wore the system down before pricing the job. 84 severe weather events were recorded in Shelby County, Texas between 2015 and 2024. At that rate, severe weather is a genuine part of the operating load here, but it is not so relentless that it explains every failure on its own. A refrigerant leak or a failing capacitor still points first to age and service history, and a contractor who skips that check will misread the repair.
Ductwork laid down for an older system carries its own history into every heat pump repair job: crimped flex runs, gaps at collars, insulation that has lost its rating. Half the homes in Shelby County, Texas were built in 1984 or earlier (2020-2024 ACS 5-year). A contractor who pulls a heat pump apart in a house of that vintage has to account for what the duct system has done to airflow before they can settle on what failed and why. A refrigerant issue and a restricted return can produce the same symptoms on the equipment side. That narrows to a different repair and a different bill depending on what the ductwork turns out to actually be.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit is usually where a repair starts. It houses the compressor, which does the hardest work in the system, and the condenser coil wrapped around it. When either goes wrong, the whole system feels it. A failed compressor means no conditioning at all; a damaged coil means the system runs but struggles.
Inside the house, the air handler holds the evaporator coil and the blower fan that moves conditioned air through the home. The expansion valve sits between the two coils and controls refrigerant flow. A contractor also checks the refrigerant lines connecting the units and the reversing valve, which is the part that lets a heat pump both heat and cool.
The drawing shows a typical layout, and a licensed contractor determines which parts and conditions apply to your specific house.

Severe Weather Events in Shelby County
Weather puts a load on heat pumps that steady indoor climates rarely reveal. How hard a system has to work, and how often it fails, is shaped by what the local climate throws at it.
