A contractor diagnosing a heat pump failure in San Patricio County starts with the system itself: how old the compressor is, whether the refrigerant charge has been maintained, and how the installation was done. 49 severe weather events were recorded in San Patricio County, Texas between 2015 and 2024. At that rate, severe weather is an occasional event in a system's life, not a grinding background condition. A heat pump that breaks down here broke down for reasons a contractor finds inside the cabinet, and the repair scope follows from what those components actually show.
Ductwork and electrical in a house this old were built for whatever ran in it first, then adapted over time as equipment changed. Half the homes in San Patricio County, Texas were built in 1982 or earlier (2020-2024 ACS 5-year). A contractor who opens a heat pump in stock like this finds components whose replacement parts are not always a current catalog item, and what is available shapes which repair is possible and which requires a different path entirely. That is what decides the job scope here.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit is usually the first thing a contractor opens up. It holds the compressor, which pressurizes the refrigerant, and the outdoor coil, which either pulls heat from the air or releases it depending on the season. When the system is not heating or cooling the way it should, these are the pieces a contractor looks at first.
Inside the house, the air handler moves conditioned air through the home and contains the indoor coil and the blower motor. The reversing valve, which sits inside the outdoor unit, is what allows the system to switch between heating and cooling modes. A faulty reversing valve is one of the first things a contractor checks when the system runs but delivers the wrong kind of air.
The drawing shows a general layout of these components, and a licensed contractor determines what applies to your specific house and setup.
