Sizing a central AC system for Ford County starts with what the compressor is being asked to do every summer. Homes in Ford County, KS run cooling about four months a year, from June through September. A compressor cycling through that kind of cooling load puts steady wear on the contactor and the condenser fan motor. A unit that is too small runs longer to hold temperature, and that extra runtime accelerates wear on exactly those parts. A contractor doing a load calculation here accounts for the local cooling demand before settling on equipment, because an undersized install announces itself in the first few seasons through component failure rather than comfort complaints.
Ductwork in houses this old was sized for equipment that is no longer sold. Half the homes in Ford County, Kansas were built in 1972 or earlier (2020-2024 ACS 5-year). A contractor installing central AC here will measure what the existing duct system can actually carry before anything else, because a trunk line built for a smaller, older unit may not move enough air for a modern one without changes to the runs. That gap between what the house was ducted for and what a new system delivers is where the scope of an installation job in Ford County gets settled.
What a Central AC Installation Puts in Your Home
The outdoor condenser unit sits on a concrete pad outside the house, usually beside or behind it. Inside, the air handler mounts in a utility closet, basement, or attic and moves conditioned air through the home. These two units are the core of what a contractor installs.
A copper refrigerant line set runs between the outdoor and indoor units, connecting them through an exterior wall. The thermostat goes on an interior wall where it can read the home's air temperature and signal the system to run.
The drawing shows a typical layout, and a licensed contractor determines exactly how the system comes together in your home.

What happens on installation day
Split-system central air conditioners rated below 45,000 Btu/h manufactured on or after January 1, 2023 must meet a federal minimum of 13.4 SEER2.
Split-system central air conditioners rated at or above 45,000 Btu/h manufactured on or after January 1, 2023 must meet a federal minimum of 13.4 SEER2.
Split-system central air conditioners manufactured between January 1, 2015 and December 31, 2022 had to meet 13 SEER, the metric that preceded SEER2.
Single-package central air conditioners manufactured on or after January 1, 2023 must meet a federal minimum of 13.4 SEER2.
Space-constrained central air conditioners manufactured on or after January 1, 2023 must meet a federal minimum of 11.7 SEER2.
Federal efficiency standards for split-system central air conditioners and heat pumps are set on each certified combination of outdoor unit and indoor coil rather than on the outdoor unit alone.
Residential and light commercial air conditioning and heat pump systems assembled in the field, including mini-splits and unitary systems, may not be installed on or after January 1, 2025 using a refrigerant with a global warming potential above 700.
A field-assembled system whose specified components were all manufactured or imported before January 1, 2025 carries no installation compliance date under the refrigerant restrictions and may still be installed.
