Sizing a heat pump for Lawrence County requires accounting for what the climate here regularly delivers, not what a standard regional chart suggests. 77 severe weather events were recorded in Lawrence County, Kentucky between 2015 and 2024. At that rate, severe weather is a standing condition in this area, and a contractor who ignores it when calculating heating and cooling loads will specify equipment that runs harder than it should from the first season. A unit sized correctly for this county handles the range of conditions the climate actually produces. One sized for a milder place does not.
Ductwork laid for an older heating system carries assumptions about airflow that a heat pump does not share, and in Lawrence County a sizable share of the housing stock was built under exactly those assumptions. Half the homes in Lawrence County, Kentucky were built in 1989 or earlier (2020-2024 ACS 5-year). A contractor pricing a heat pump installation here sizes the new unit and then turns to what is already in the walls: whether the duct runs can move the volume the equipment needs, and whether the electrical service meets the load it draws. Those two questions, answered from what the house actually contains rather than from its age alone, are what set the scope of the job.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece a homeowner sees first, sitting on a pad beside the house. Inside, the air handler mounts in a closet, basement, or utility space and moves conditioned air through the home. Together these two cabinets form the core of what a contractor puts in.
A refrigerant line set runs between the outdoor unit and the air handler, carrying the working fluid that lets the two cabinets communicate. A thermostat goes on an interior wall where it reads the living space and tells the system when to run. A condensate drain line runs from the air handler to a suitable drain point nearby.
The drawing shows a representative layout, and a licensed contractor determines exactly how these pieces are positioned and connected in your specific home.

Severe Weather Events in Lawrence County
Heating and cooling equipment in Lawrence County works against whatever the local climate throws at it, and that load shapes what a heat pump here needs to handle. Weather history is part of sizing and installation decisions, which is why it belongs on a page about this work.
