A contractor quoting central AC in Monroe County starts with what the house actually needs: square footage, insulation, sun exposure, and how the ductwork is laid out. 62 severe weather events were recorded in Monroe County, West Virginia between 2015 and 2024. At that rate, severe weather is an occasional fact of life here, not a constant operating pressure, so a bad season alone is unlikely to be what drives an early replacement. The sizing decisions and the quality of the original install carry far more weight in how long a new system performs.
Ductwork sized and routed for a different era of equipment shapes every central AC installation in this county more than the unit itself does. Half the homes in Monroe County, West Virginia were built in 1978 or earlier (2020-2024 ACS 5-year). A contractor who installs a new system in a house from that period has to assess whether the existing duct layout moves enough air, whether the runs are sealed, and whether the electrical service handles the load a modern condenser draws. Those are questions the house answers, and the answers vary room to room. Some houses need only a new unit tied in; others need duct work done before anything else gets priced.
What Gets Installed With a New Central AC
The outdoor condenser unit sits on a concrete pad outside the house and holds the compressor and condenser coil. Inside, the air handler mounts in a utility closet, basement, or attic and contains the evaporator coil and blower that moves conditioned air through the home. These two units are the core of what a contractor sets in place.
A pair of refrigerant lines runs between the outdoor and indoor units, connecting them through a small penetration in the wall or foundation. The thermostat goes on an interior wall where it reads the home's temperature and tells the system when to run. A condensate drain line also gets routed from the air handler to carry away the moisture the coil pulls from the air.
The drawing shows how these pieces relate in a typical installation, and a licensed contractor determines exactly how they fit the layout of your house.

What HVAC Installation Looks Like in Monroe 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.
