Sizing a heat pump for Tulare County starts with the heating load, not the cooling one. Homes in Tulare County, CA run heat about eight months a year, from October through May. A heat pump's capacity drops as outdoor temperatures fall, so the coldest weeks of that run are the ones a contractor has to size against, not the mild middle of it. A unit that handles October and April without trouble can still fall short in January, and once it is installed that shortfall is fixed. The load calculation done before the quote is what keeps a contractor from undersizing the refrigerant circuit or the backup heat strip for a house that will lean on both.
Ductwork designed around equipment that no longer runs in these houses is where a heat pump installation in Tulare County gets settled or gets complicated. Half the homes in Tulare County, California were built in 1983 or earlier (2020-2024 ACS 5-year). A contractor putting in a heat pump has to establish whether the existing duct system can move the volume of air the new unit requires, and whether the electrical service will carry the load. Those two questions get answered by opening walls and reading the panel, and the answers determine the scope of the job before the equipment itself is priced.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece most homeowners see first. It sits on a concrete pad or wall bracket outside the house and holds the compressor and the outdoor coil. Inside, the air handler mounts in a closet, attic, or utility room and circulates conditioned air through the home.
A refrigerant line set runs between the two units, carrying refrigerant through insulated copper tubing that passes through an exterior wall. A thermostat goes on an interior wall and gives the homeowner control over the whole system.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines exactly how these pieces fit the conditions of your particular house.
