Takes about a minute. No obligation.
A contractor diagnosing a central AC problem here starts with the parts that take the hardest mechanical punishment each season: the contactor, the capacitor, and the condenser fan motor. Homes in Morgan County, CO run cooling about three months a year, from June through August. The compressor starts and stops hundreds of times across that window, and the contactor closes every single time. That cycling burns contact surfaces and stresses capacitors in ways that refrigerant charge and coil condition rarely match. A repair quote that skips those components and goes straight to refrigerant work is likely missing where the actual wear landed.
Half the homes in Morgan County, Colorado were built in 1975 or earlier (2020-2024 ACS 5-year). A system that has been running in a house this long carries what those years ask of it: compressor wear, refrigerant line degradation, and capacitors that have cycled far past their rated life. When a contractor opens the unit, the question is rarely which part to order and often whether the part is still manufactured. Stock this old runs equipment that predates the current parts catalogs, and a repair quote depends on what the opened system actually contains, not on the age printed on the permit.
The Parts of a Central AC a Contractor Checks During Repair
The outdoor condenser unit sits outside the house, usually on a concrete pad at ground level, and it holds the compressor and condenser coil. These are the pieces a contractor reaches first when the system stops cooling, because a failed compressor or a fouled coil accounts for a wide range of common breakdowns. The indoor air handler or furnace-mounted evaporator coil sits inside, and a refrigerant leak or a frozen coil there can shut down the whole system just as completely.
The copper refrigerant lines run between the two units, and a contractor checks them for leaks or insulation damage that starves the system of charge. The expansion valve and the metering device that feeds refrigerant into the evaporator coil also draw attention when cooling is weak but the compressor runs. The thermostat and its wiring are checked early too, since a wiring fault or a failed thermostat can mimic a mechanical failure in the equipment itself.
The drawing shows a typical layout, and a licensed contractor determines which components and conditions apply to this particular house.

What HVAC Repair Looks Like in Morgan 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 Morgan County
Extreme weather puts real stress on cooling equipment, running compressors and capacitors harder and shortening the window before something fails. How much of that load a system carries depends on what the local climate actually does, and in Morgan County that is a local repair question.
