Not sure what size air conditioner your home needs? Enter a few details below for a quick tonnage and BTU estimate tuned for Middle Georgia's hot, humid summers. It is a great starting point, and we will confirm the exact size with a free in home load calculation.
Why the Right Size Matters
Bigger is not better with air conditioning. An oversized unit short cycles and leaves your home humid and clammy, while an undersized unit runs constantly and struggles on the hottest days. Correct sizing keeps you comfortable, lowers your energy bill, and helps the equipment last longer.
AC Sizing Questions
What size air conditioner do I need for my house?
A rough rule of thumb is one ton of cooling for every 400 to 600 square feet, but the right size depends on your ceiling height, sun exposure, insulation, and Georgia's heat and humidity. Our calculator gives a quick estimate, and a proper Manual J load calculation during an in home visit confirms the exact size.
Is it better to oversize my AC to be safe?
No. An oversized system short cycles, turning on and off too often. That wastes energy, leaves the air feeling clammy because it never runs long enough to remove humidity, and wears the equipment out faster. Right sizing matters more than bigger.
