AC Installation in Washington

Sizing a central AC unit for this house is the question a contractor has to answer before anything else. Homes in Washington County, KS run cooling about three months a year, from June through August. The compressor starts and stops only during those months, so total runtime on the contactor and condenser fan stays low year over year. A system that fails early here points back to the original install: a unit that was undersized for the house's heat load, or ductwork that was never balanced to deliver air where the rooms needed it. Long idle periods also let refrigerant leaks go unnoticed until the first call of summer, which is why a contractor commissioning a new system pressure-tests before handing it off.

Ductwork laid out for a much older system shapes what a contractor can and cannot do with a new central AC unit. The routing, the sizing, the supply and return positions: all of it was designed around equipment that is long gone, and a new unit has to work within those choices or the ducts have to change. Half the homes in Washington County, Kansas were built in 1953 or earlier (2020-2024 ACS 5-year). That history shows up in the electrical too, where service panels sized for lighter loads sometimes need upgrading before a new system can run on them. What a contractor quotes in Washington County reflects the house as much as the equipment.
