A contractor quoting a heat pump install in Duval County has to size for what the climate actually demands, and the local weather record is where that work starts. 457 severe weather events were recorded in Duval County, Florida between 2015 and 2024. At that rate, severe weather is a regular part of what any system here runs against across its service life, which means equipment capacity and installation quality are not generic catalog decisions. A unit undersized for this load runs harder, more often, and shows strain in the compressor and refrigerant circuit before a well-matched system would. The contractor's first job is matching the unit to the real thermal and weather load this address carries.
Ductwork sized and routed for a different era of equipment is what a contractor opens the job with in much of Duval County. Half the homes in Duval County, Florida were built in 1986 or earlier (2020-2024 ACS 5-year). A heat pump moves air differently than what many of these systems were originally built around, and whether the existing duct layout can carry that load without modification is the question that shapes the quote. The electrical service gets the same scrutiny. What the contractor finds in both determines the scope before the unit itself is priced.
What Gets Installed With a New Heat Pump
The outdoor unit sits on a pad beside the house and holds the compressor and the condenser coil. The indoor air handler mounts inside, usually in a closet, attic, or utility room, and pushes conditioned air through the home. Together, these two units are the core of what a contractor installs.
A refrigerant line set runs between the two units, carrying refrigerant back and forth through insulated copper tubing. A thermostat goes on an interior wall and gives the homeowner control over the system. The contractor also installs a condensate drain line from the air handler to move moisture out of the house.
The drawing shows a typical layout, and a licensed contractor determines what applies to your specific home.

Severe Weather in Duval County
Florida's climate puts real demands on heating and cooling equipment, and Duval County gets its share of what the atmosphere delivers. A heat pump sized and installed for local conditions carries that load better than one spec'd for somewhere else.
