Takes about a minute. No obligation.
The compressor in a central AC unit starts and stops repeatedly across the cooling months, and that cycling is where the wear lands. Homes in Kent County, DE run cooling about three months a year, from June through August. Because the season is compressed rather than spread across most of the calendar, the contactor, the capacitor, and the condenser fan motor absorb the bulk of the stress in a short window. A contractor pulling a service call here checks those components first, since they are the ones that have actually been working. Refrigerant charge and coil condition follow.
Ductwork in a house carries whatever system a contractor put in it last, but the opened unit is what sets the terms of a repair. Half the homes in Kent County, Delaware were built in 1993 or earlier (2020-2024 ACS 5-year). A system running in stock that old has likely been replaced at least once, which means the refrigerant lines, the air handler, and the condenser outside are each a different vintage. When a technician opens a failing unit, the question that drives the bill is whether the part it needs still has a supply chain. Compressor valves, control boards, and motor assemblies for older equipment are the first things to go scarce, and a part that cannot be sourced turns a repair into a replacement whether the homeowner planned for one or not.
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. These are the parts a contractor goes to first when a system is running but not cooling, because a failed compressor or a fouled coil will kill performance before anything else shows up.
Inside the house, the air handler holds the evaporator coil and the blower that pulls air across it. The refrigerant lines connect the two units, and the thermostat tells the whole system when to run. A fault in any of these can look like a compressor problem until a contractor traces it back to its source.
The drawing shows a typical central AC layout, and a licensed contractor determines which components apply to your specific house and setup.

What Happens When the Contractor Arrives
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.
Licensing and Legal Requirements in Kent County, Delaware
Delaware requires a state licence to provide HVACR services, and forbids holding yourself out as a master HVACR licensee without one.
Severe Weather Events in Kent County
Storm activity puts real stress on central AC systems: power surges, prolonged run times, and moisture intrusion all accelerate wear. How much of that your equipment faces depends on what the local weather actually does.
