A contractor quoting a heat pump install in Love County has to size the unit for what this area actually demands, and that means the weather record here is a starting point, not a footnote. 97 severe weather events were recorded in Love County, Oklahoma between 2015 and 2024. At that rate, severe weather is a standing feature of the local climate, and a system sized too small will run long hours trying to keep up before it has aged enough to have earned the wear. Contractors who know this area factor that load into equipment selection and installation quality from the first site visit.

An unfinished attic with wooden rafters, plywood decking and loose fiberglass insulation between joists, with a flexible foil-wrapped duct running along the floor toward two cardboard boxes at the far end.

Ductwork laid out for a furnace and central air system was designed around different airflow volumes and static pressure ranges than a heat pump requires. Half the homes in Love County, Oklahoma were built in 1984 or earlier (2020-2024 ACS 5-year). That gap between what the ducts were built to move and what a new heat pump asks of them is where installation jobs in this county get complicated or expensive. A contractor who quotes the unit without walking the duct runs is pricing the wrong thing first.

What a Heat Pump Installation Puts in Your Home

The outdoor unit sits on a pad beside the house and holds the compressor and the heat exchange coil, which together do the bulk of the work. Inside, the air handler mounts in a utility space, a closet, or an attic and moves conditioned air through the home. These two units are the core of what a contractor puts in place.

A pair of refrigerant lines run between the outdoor unit and the air handler, connecting the two halves of the system. The thermostat goes on an interior wall and gives the homeowner control over when and how the system runs. A condensate drain line also runs from the air handler to carry away moisture the coil pulls from the air.

The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits the specifics of your house.
