Sizing a central AC system for a house in Wells County starts with what the building actually needs, not with assumptions borrowed from harsher climates. 68 severe weather events were recorded in Wells County, Indiana between 2015 and 2024. At that rate, severe weather is a periodic event here, not a standing condition the equipment fights through every season. A contractor quoting a new install is focused on duct layout, load calculations, and whether the equipment matches the structure, because those are the variables that decide how well the system performs and how long it lasts. Weather load is real, but it does not dominate the sizing conversation the way it would in a county where the skies are reliably punishing.
Ductwork laid down for an older furnace and electrical service sized for a different era of equipment are what a contractor has to evaluate before a central AC installation in Wells County can be quoted or sized accurately. Half the homes in Wells County, Indiana were built in 1973 or earlier (2020-2024 ACS 5-year). That gap between when the building was designed and what a modern central AC unit actually draws is where installs stall or change scope. A panel that looked adequate on paper turns out to need an upgrade; a duct run that served the old system does not move air the way a new unit requires. The equipment itself gets specified once the house is understood.
What Gets Installed With a New Central AC
The outdoor condenser unit sits outside the house, usually on a concrete pad beside the foundation, and holds the compressor and the condenser coil. Inside, the air handler or furnace-mounted evaporator coil sits in a utility room, basement, or attic and is the indoor half of the system. These two units are what a homeowner is buying.
A refrigerant line set connects the outdoor and indoor units, running through the wall or floor between them. The thermostat goes on an interior wall where it reads the temperature of the living space and signals the system to run. A condensate drain line also runs from the indoor coil to a floor drain or outside, carrying away the moisture the coil pulls from the air.
The drawing shows a typical layout, and a licensed contractor determines what fits this house specifically.

What happens on installation day in Wells County
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.
Severe Weather Events in Wells County
Weather conditions place real demand on cooling equipment, and that demand varies by location. What the climate does in Wells County shapes how hard a central AC system has to work and how well it needs to be sized and installed to hold up over time.
