A contractor quoting a heat pump installation in San Patricio County is not building around a punishing storm record. 49 severe weather events were recorded in San Patricio County, Texas between 2015 and 2024. At that rate, severe weather is an event, not a condition, and it does not drive the sizing decisions the way it would in counties where the air equipment runs against is consistently violent. What shapes the install here is the home itself: duct layout, existing infrastructure, and how the system will be loaded day to day. A contractor who anchors the quote around storm resilience is answering a question this county's record does not ask.
Ductwork laid in for older cooling and heating equipment carries assumptions about static pressure, trunk sizing, and return-air volume that a heat pump does not share. Half the homes in San Patricio County, Texas were built in 1982 or earlier (2020-2024 ACS 5-year). A contractor pricing a heat pump installation here pulls those ducts into the assessment before the unit itself, because what the existing system can move determines whether the new equipment performs at its rated capacity or fights the house on every cycle. Electrical service gets the same look: branch circuits and panel capacity from that era were not planned around the draw a heat pump compressor puts on them.
What a Heat Pump Installation Puts in Your Home
The outdoor unit sits on a pad beside the house and holds the compressor and the coil that exchange heat with the outside air. Inside, an air handler mounts in a closet, attic, or utility space and pushes conditioned air through the home. These two pieces are the core of what a contractor brings to the job.
A refrigerant line set runs between the outdoor unit and the air handler, connecting the two halves of the system. A thermostat goes on an interior wall where it reads the home's temperature and tells the system when to run. Both pieces are part of what a full installation covers.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece applies to your house.

Severe Weather Events in San Patricio County
Weather puts a measurable load on heating and cooling equipment, and that load varies by location. What rolls through San Patricio County shapes how hard a heat pump has to work and how well it needs to be sized and installed to hold up.
