Takes about a minute. No obligation.
A heat pump in Lake County has been running against real weather pressure, and a contractor diagnosing a repair here will check the components that bear that load first: the compressor, capacitor, and contactor wear in ways that reflect how hard the system has been pushed. 87 severe weather events were recorded in Lake County, Florida between 2015 and 2024. At that rate, severe weather is a standing feature of operating a heat pump here, not an occasional event, and a contractor who skips checking those components risks misreading a weather-driven failure as simple age. The repair scope follows from what the opened system actually shows.
Ductwork and electrical panels in stock of this vintage were sized for systems that look a lot like what runs in them today, so they rarely become the story when a heat pump breaks down. Half the homes in Lake County, Florida were built in 1997 or earlier (2020-2024 ACS 5-year). What a contractor finds once the unit is open tends to settle the job: a failed contactor, a refrigerant leak at a corroded fitting, or a capacitor that has given out. Those parts either test bad or they test fine, and the repair scope follows from that, not from the building around it.
The Parts of a Heat Pump a Contractor Checks During Repair
The outdoor unit is the piece most homeowners recognize on sight. It holds the compressor, which is the heart of the system, along with the outdoor coil and a large fan. When a heat pump stops moving air or loses heating and cooling capacity, the compressor and outdoor coil are where a contractor looks first.
Inside the house, the air handler contains the indoor coil and the blower that pushes conditioned air through the home. A reversing valve connects the two sides of the system and is what lets a heat pump shift between heating and cooling modes. A fault in that valve or in the refrigerant lines running between the units shows up as the system doing only half its job.
The drawing shows a typical layout, and a licensed contractor determines which components apply to your specific system and what each one needs.

Severe Weather Events in Lake County
Florida's climate puts heat pump systems under sustained pressure that milder regions never see. How hard local weather bears on a system shapes how often that system needs attention, and Lake County conditions are a direct part of that picture.
