A heat pump repair diagnosis in Seminole County starts with a question about history: what has this system actually been running against? 94 severe weather events were recorded in Seminole County, Florida between 2015 and 2024. At that rate, severe weather is a standing condition of operating here, and a contractor looking at a failed component has to separate ordinary wear from load accumulated through years of rough weather before they can tell you what needs replacing and why.
Ductwork and wiring in a house this old were put in for equipment that no longer exists. Half the homes in Seminole County, Florida were built in 1988 or earlier (2020-2024 ACS 5-year). When a contractor opens a heat pump in a house from that era, the lines feeding it and the connections behind the air handler often belong to an earlier system, adapted rather than replaced. Parts for the heat pump may still be made; getting to them cleanly is a different question when the surrounding infrastructure was never sized for it.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit is the piece most homeowners recognize on sight. It sits outside the house and holds the compressor and the condenser coil. The compressor is where a contractor looks first when a heat pump stops heating or cooling altogether, because it is the part that does the hardest mechanical work. A failed capacitor, a refrigerant leak, or a seized compressor all show up here.
Inside the house, the air handler holds the evaporator coil and the blower fan, moving conditioned air through the home. The reversing valve, which sits in the outdoor unit, is what lets a heat pump shift between heating and cooling modes, and it is a common repair target when the system runs but delivers the wrong temperature. The expansion valve and the refrigerant lines that run between both units round out what a contractor traces when a problem is not obvious at first look.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines which components apply and what needs attention in your specific home.

Severe Weather Events in Seminole County
Florida's weather puts real stress on heat pump equipment, and Seminole County gets its share. Every storm cycle, humidity spike, and power disruption adds to the cumulative load a unit carries, which is why local repair demand is shaped as much by what the sky does as by equipment age.
