Sizing a heat pump for Kings County starts with understanding what the heating side actually demands. Homes in Kings County, CA run heat about six months a year, from November through April. Through those months, outdoor temperatures on the coldest nights push against the lower edge of a heat pump's capacity curve, and a unit that looks adequate on paper can fall short when the thermostat needs it most. A contractor has to run a proper load calculation and settle the back-up heat question before selecting equipment, because an undersized install does not reveal itself until the homeowner is already cold.
Ductwork and electrical panels in much of this county's housing were built for systems that no longer exist in most of those houses. Half the homes in Kings County, California were built in 1986 or earlier (2020-2024 ACS 5-year). A heat pump draws more from a service panel than what those original panels were sized to carry, and a contractor has to open the breaker box and read what is actually there before a quote for the equipment means anything. If the panel needs upgrading, that work gets priced and scheduled alongside the unit, not after it.
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 a homeowner sees. Inside, the air handler mounts in a utility closet, attic, or basement and moves conditioned air through the home.
A refrigerant line set runs between the two units, carrying the working fluid that lets them act as one system. A thermostat goes on an interior wall and gives the homeowner control over the whole thing. Some installations also include a supplemental electric resistance element inside the air handler for very cold days.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits into your home.
