A contractor quoting a heat pump install in Fayette County has to size the system around what this area actually asks of it, not around a catalog default. 143 severe weather events were recorded in Fayette County, Kentucky between 2015 and 2024. At that rate of severe weather, the heating and cooling loads a system faces here are not occasional spikes but part of normal operation, which means an undersized unit will run harder and longer than its design accounts for. A contractor who gets the load calculation right before selecting equipment avoids the failure that follows from a unit that was never adequate for this address.
Ductwork laid down for one generation of equipment does not automatically carry the next. Half the homes in Fayette County, Kentucky were built in 1984 or earlier (2020-2024 ACS 5-year). A heat pump moves air differently than what most of that stock was originally built around, and the ducts reflect the priorities of whoever installed them first. A contractor fitting a new unit here pulls the duct layout and the electrical service into the quote before the equipment choice is settled, because those two things set the floor on what the job actually takes.
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. It is the largest piece of the installation and the one a visitor would spot immediately. Inside, the air handler mounts in a utility closet, attic, or basement and contains the blower fan and the indoor coil that conditions the air moving through your home.
A refrigerant line set runs between the two units, carrying the working fluid that lets them function as a single system. A thermostat goes on an interior wall where it reads the living space and tells both units what to do. Some installations also include a supplemental electric resistance strip inside the air handler, which a contractor fits when the local climate calls for backup heat.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece is positioned and connected in your house.

Severe Weather Events in Fayette County, Year by Year
Extreme weather puts direct stress on heating and cooling equipment, shortening service life and driving up energy draw during the hours it matters most. How often that pressure hits in Fayette County shapes what a heat pump here needs to handle and how it should be sized and installed.
