Sizing a New AC for a Greensboro Home
Short answer: a properly sized AC runs long enough to remove humidity and keep temperatures even. Bigger is not better. Ask for a load calculation, not a guess based on square footage or the old unit's size.
Request an AC technicianOversizing
Short cycles, uneven temperatures and clammy air.
Undersizing
Runs constantly and can't keep up on the hottest days.
Load calculation
Considers insulation, windows, orientation and air leaks.
Square footage
A rough start, but not enough on its own.
Ducts
A new system needs ducts that can carry its airflow.
Variable speed
Adjusts output to match the load.
Humidity
Right-sizing improves moisture removal.
Zoning
Two-story homes may benefit from zones or two systems.
Efficiency
Higher ratings save more over a long season.
Quotes
Compare equipment, sizing and scope, not just price.
Warranty
Ask about registration and labor coverage.
