Takes about a minute. No obligation.
A central AC compressor in Niagara County spends most of its calendar standing still. Homes in Niagara County, NY run cooling about two months a year, from July through August. The contactor, the capacitor, and the condenser fan motor are all subject to degradation during long off periods, not just from running. Seals dry, electrical connections oxidize, and a refrigerant leak that started in September goes unnoticed until July. A contractor diagnosing a failure here checks for that kind of dormancy-related damage before pricing parts, because the fault often predates the call by months.
Ductwork laid out for a furnace and a gravity system carries refrigerant lines and filter returns that were added later, and what sits behind a service panel in a house like this reflects the same layered history. Half the homes in Niagara County, New York were built in 1958 or earlier (2020-2024 ACS 5-year). When a compressor or air handler comes apart, the parts inside often belong to a replacement cycle that has already run more than once, and the components a technician needs may be sourced rather than pulled from a distributor's shelf. That is the repair the age of this housing stock actually predicts.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad at ground level, and it is where heat gets pushed out of the building. The indoor air handler or furnace coil lives inside, often in a basement, attic, or utility closet, and it is the piece that gets cold and cools the air moving past it. These two units are the first places a contractor looks when a system stops cooling.
A copper refrigerant line set runs between the indoor and outdoor units, carrying the refrigerant that makes the whole exchange possible. The thermostat on the wall is the control point, and when it reads or signals incorrectly, every other piece behaves as though it has failed. The condensate drain handles the moisture the indoor coil pulls from the air, and a blocked drain is a common source of water damage and shutdowns.
The drawing shows the general layout of a central AC system, and a licensed contractor determines which components and conditions apply to your specific home.

What HVAC Repair Looks Like in Niagara 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.
