Why AC size matters more than brand

Oversized and undersized air conditioners both cost you comfort.

An oversized air conditioner cools the house quickly, shuts off, and never runs long enough to remove humidity — so the home feels cold and clammy.

An undersized unit runs all afternoon on hot days and still can't keep the upstairs comfortable.

The right size comes from a cooling-load calculation that looks at your windows, insulation, orientation and ductwork — not the size of the old unit.

We do that calculation for every new system we quote.
