A contractor repairing a heat pump here has to settle one question before anything else: which components wore out under sustained weather load, and which gave out for reasons the weather had nothing to do with. 285 severe weather events were recorded in Smith County, Texas between 2015 and 2024. At that rate, severe weather is a standing feature of operating in this county, and the refrigerant lines, capacitors, and contactors on any system here have been carrying that load steadily. A diagnosis that skips that history risks replacing a part that failed for the wrong reason and leaving the real one in place.
Opened equipment in a heat pump repair tells you things the age of the house cannot. Half the homes in Smith County, Texas were built in 1986 or earlier (2020-2024 ACS 5-year). That spread means contractors working in Smith County regularly pull covers off systems whose internal components reflect years of prior service, piecemeal replacement, and wear patterns that differ unit to unit. Whether a part is still manufactured, and in what form, is a question the opened system answers. A quote built before that inspection is a guess.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit is the piece most homeowners can point to right away. It sits outside the house and holds the compressor and the condenser coil. The compressor is the part a contractor goes to first when a heat pump stops moving heat, because a failed compressor is the difference between a system that runs and one that does not.
Inside the house, the air handler contains the evaporator coil and the blower. The evaporator coil is where refrigerant problems show up as ice or as air that never reaches the right temperature, and the blower is what a contractor checks when airflow across the house turns uneven. The refrigerant lines connecting both units are also inspected, since a leak there affects everything the system tries to do.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines which parts apply to your specific house and what work each one needs.
