A contractor quoting a heat pump install in Polk County has to price for real operating conditions, and the weather record here is part of that calculation. 94 severe weather events were recorded in Polk County, Florida between 2015 and 2024. Severe weather at that rate means a system runs harder and longer to recover after each event, which pushes demand-load figures above what a catalog spec built for mild conditions assumes. A unit sized to a generic load will run at capacity more often than designed, shortening the life of components that might otherwise last. Contractors who know this area size and install accordingly.
Ductwork sized for a different system is what a contractor finds in a large share of homes here. Half the homes in Polk County, Florida were built in 1992 or earlier (2020-2024 ACS 5-year). That matters for a heat pump installation because a heat pump moves air at lower temperatures and higher volumes than older cooling equipment did, and ducts laid out for the latter can create pressure and airflow problems the new unit cannot correct on its own. The electrical panel is the second check. Both are in the house before anyone prices the equipment.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece most homeowners notice first. It sits on a concrete pad outside the house and holds the compressor and the outdoor coil, which together do the work of moving heat. Inside, the air handler mounts in a closet, attic, or utility room and circulates conditioned air through the home.
A refrigerant line set runs between the two units, connecting them through a small penetration in the wall. A thermostat goes on an interior wall where it can read the living space and signal the system when to run. Some installations also include a supplemental electric heat strip inside the air handler for the coldest nights.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits the conditions in your house.

Severe Weather Events in Polk County
Florida weather puts real stress on heating and cooling equipment, and Polk County's conditions are their own. A heat pump sized and installed for local weather loads lasts longer and runs more efficiently than one treated as a generic job.
