Takes about a minute. No obligation.
The compressor in a central AC unit sits dormant through most of the year in Washington County, then starts hard when summer arrives. Homes in Washington County, KS run cooling about three months a year, from June through August. Contactors and capacitors carry the stress of those first startups after months of no use, and those are the parts a contractor checks when a system that worked last August refuses to turn on in June. A failed start capacitor costs far less than a seized compressor, but only if a technician catches it before the compressor labors through a failed start cycle and burns out.
Ductwork in these houses was sized and routed for systems that have long since been replaced, sometimes more than once, and the components inside a unit running on that original infrastructure may draw from a parts catalog that has thinned considerably. Half the homes in Washington County, Kansas were built in 1953 or earlier (2020-2024 ACS 5-year). When a contractor opens a failing system here, the question is not just what broke but whether a replacement part still exists, or whether the repair requires fabrication, substitution, or a different scope entirely. Stock this old carries that uncertainty in ways newer housing does not force.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad beside the foundation, and it carries the compressor and the condenser coil. Both are common repair targets. A failed compressor means the system runs but produces no cooling, while a dirty or damaged condenser coil forces the compressor to work harder than it should.
Inside the house, the air handler holds the evaporator coil and the blower. The evaporator coil sits where warm indoor air passes over it, and a refrigerant leak or a frozen coil points here. The blower motor pushes air through the system, and a contractor checks it when airflow is weak or absent even though the unit appears to be running.
The drawing shows a typical layout, and a licensed contractor determines which components apply to your specific system and what repair each one needs.

What HVAC Repair Looks Like in Washington 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.
