A contractor sizing and installing central AC in Poquoson has to account for what the local climate actually demands, and that starts with an honest read of the weather record. 12 severe weather events were recorded in Poquoson city, Virginia between 2015 and 2024. At that rate, severe weather is an event here, not a background condition every system fights through season after season. A contractor who lets that record do too much work in the quote is pointing at the wrong variable. Duct layout, equipment sizing, and installation quality are what determine whether a new system handles summer heat or struggles against it from day one.
Ductwork laid in for an older system carries assumptions about static pressure, room-by-room airflow, and return placement that a new central AC unit does not share. Half the homes in Poquoson city, Virginia were built in 1977 or earlier (2020-2024 ACS 5-year). A contractor quoting a new system has to assess whether the existing duct network can move the volume the new equipment pushes, and in houses of this vintage the answer often means adding returns, resizing trunk lines, or sealing what has worked loose over decades of use. The electrical service is the second check: panel capacity and the circuit feeding the air handler have to match what the new equipment draws. Both are site questions, not catalog questions.
What Gets Installed With a New Central AC
The outdoor condenser unit sits on a concrete pad beside the house and holds the compressor and condenser coil, the two components that shed heat outside. Inside, the air handler mounts in a utility closet, basement, or attic and circulates conditioned air through the home. These are the core pieces a homeowner is buying.
The evaporator coil attaches directly to the air handler, where it does the cooling work on the air passing through. A copper refrigerant line set runs between the indoor and outdoor units, connecting them, and a condensate drain line carries moisture away from the evaporator coil to a floor drain or outside.
The drawing shows the general layout of a central AC system, and a licensed contractor determines exactly how each piece applies to your house.

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.
