Takes about a minute. No obligation.
A contractor quoting a central AC installation in this county has to size for what the climate actually demands, not for a quieter place and not for somewhere that sees severe weather as a constant siege. 108 severe weather events were recorded in Pocahontas County, Iowa between 2015 and 2024. At that rate, severe weather is a recurring pressure on outdoor equipment rather than a rare exception, and a properly sized unit with sound line-set work and well-sealed ductwork carries that load without it becoming the story of every service call. The install itself is where the margin gets built in.
Ductwork and electrical service put in for an older generation of equipment shape every central AC installation in this county. Half the homes in Pocahontas County, Iowa were built in 1950 or earlier (2020-2024 ACS 5-year). A contractor sizing a new system has to assess whether the existing duct layout can actually move the air a modern unit produces, and whether the panel will carry the load it draws. Those two questions, not the unit itself, determine what the job costs and how long it takes to scope.
What Goes Into a Central AC Installation
The outdoor condenser unit sits on a concrete pad beside the house and holds the compressor and condenser coil. Inside, the air handler or furnace-mounted evaporator coil lives in a utility space, basement, or closet and is the piece the cooled air passes through before moving into the home.
The refrigerant line set runs between those two units, connecting them through an exterior wall. A thermostat mounts on an interior wall and gives the homeowner control over the whole system. Both pieces are part of what a contractor installs when putting in a new central AC.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to your house.

What the Installation Actually Looks Like
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.
