A heat pump spec that works in a calmer part of Florida can fall short here if the contractor has not accounted for what this area regularly puts equipment through. 94 severe weather events were recorded in Seminole County, Florida between 2015 and 2024. At that rate of events, outdoor conditions are an active variable in sizing, not background noise, and a contractor who ignores them risks installing a unit that runs at its limits from the first season. Capacity, refrigerant line routing, and pad placement all get decided with the real operating environment in mind.
Existing ductwork is what a contractor prices hardest in a Seminole County heat pump job. Half the homes in Seminole County, Florida were built in 1988 or earlier (2020-2024 ACS 5-year). Duct runs laid in for older equipment carry assumptions about airflow, return sizing, and static pressure that a heat pump does not share, and the electrical service in houses of that vintage often needs assessment before a new unit goes in. Whether the ducts stay, get modified, or get replaced is where the installation scope is actually set.
What Gets Installed With a New Heat Pump
The outdoor unit sits on a pad beside the house and holds the compressor and coil that do the system's main work. Inside, the air handler mounts in a closet, attic, or utility room and moves conditioned air through the home. These are the two pieces a homeowner buys when they go with a heat pump.
A refrigerant line set runs between the outdoor unit and the air handler, connecting the two halves of the system through the wall or ceiling. A thermostat goes on an interior wall where it reads the home's temperature and tells the system when to run.

Severe Weather Events in Seminole County
Florida weather puts real stress on heating and cooling equipment, and Seminole County gets its share of conditions that push systems hard. A heat pump sized and installed for local demands handles that load differently than one spec'd for a milder climate.
