Takes about a minute. No obligation.
A heat pump going in here is sized against a climate that runs hard. 220 severe weather events were recorded in Le Flore County, Oklahoma between 2015 and 2024. At that rate, severe weather is part of the normal operating envelope, and a contractor quoting an install factors it in from the start: refrigerant line placement, unit siting, and the structural ratings of the mounting all reflect what the system will regularly face. Skipping that work produces a system that meets the catalog spec and misses the actual site.
Ductwork laid out for a different kind of system is what a contractor has to assess before a heat pump job can be priced accurately. Half the homes in Le Flore County, Oklahoma were built in 1985 or earlier (2020-2024 ACS 5-year). That puts a large share of the county's housing in a range where original duct runs were designed around equipment with different airflow requirements than a heat pump carries. A contractor will check whether existing trunk lines and branch runs can handle the static pressure a heat pump moves, and whether any sections need to be rebalanced or replaced before the new unit goes in. The electrical service gets checked too, but duct layout is where the scope of this job usually opens up.
What a Heat Pump Installation Puts in Your Home
The outdoor unit is the piece most homeowners see first, a cabinet that sits on a pad or brackets outside the house and holds the compressor and one set of coils. Inside, the air handler mounts in a closet, attic, or mechanical room and moves conditioned air through the home. Together these two units are what a new installation places.
A refrigerant line set runs between the outdoor unit and the air handler, connecting the two through a wall or chase. A thermostat goes on an interior wall and gives the homeowner control over the whole system. Some installations also include an auxiliary or backup heat strip inside the air handler for the coldest days.
The drawing shows a typical layout, and a licensed contractor determines what the configuration looks like in your specific house.
