A heat pump installed in this county is not going into a mild operating environment. 115 severe weather events were recorded in Ashtabula County, Ohio between 2015 and 2024. At that rate, severe weather is part of what every system here runs against across its life, and a contractor who ignores it when sizing equipment or designing the install will produce a system that fits a different county. Refrigerant line routing, outdoor unit placement, and electrical spec all carry more consequence here than in places where the climate asks less of the equipment.
Ductwork put in for a furnace was sized around a different airflow velocity than a heat pump needs, and in Ashtabula County a contractor quoting a heat pump job has to treat what is already in the walls as an open question. Half the homes in Ashtabula County, Ohio were built in 1962 or earlier (2020-2024 ACS 5-year). Stock built in that era was ducted for forced-air heat at delivery temperatures a heat pump does not reach, which means the duct layout and register placement that worked then can underperform with the new system. A contractor assessing the job measures and inspects the existing runs before the equipment gets ordered.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece most homeowners notice first. It sits on a concrete pad or wall bracket outside the house and holds the compressor and the outdoor coil, which together do the heavy work of moving heat between outside air and the refrigerant. The indoor air handler mounts in a closet, attic, or basement and pushes conditioned air through the home.
A refrigerant line set runs between the two units, carrying refrigerant back and forth through insulated copper tubing. Alongside the air handler sits the expansion valve, which controls how refrigerant enters the indoor coil, and a condensate drain line that carries away any moisture the coil pulls from the air.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to this house based on its construction and existing setup.
