What size air conditioner do I need for my home?

As a rough starting point, homes need about 20 BTU of cooling per square foot, so a 2,000 sq ft Bucks County home often needs a 3 to 3.5-ton system. But proper sizing requires a Manual J load calculation that accounts for insulation, windows, and layout. LegendAir sizes every system correctly — call (215) 317-6099 for a free assessment.

Is a bigger AC unit better?

No. An oversized air conditioner short-cycles — it cools the air quickly but shuts off before removing humidity, leaving your home cold and clammy while wearing out the compressor faster. A correctly sized unit runs longer, gentler cycles. Call LegendAir at (215) 317-6099 for proper Manual J sizing.
