AC Size / BTU Calculator for Broward County Homes

What size AC do I need for a Broward County home?

A rough Broward County AC sizing estimate starts with square footage, then adjusts for ceiling height, insulation, sun exposure, glass, and humidity load. This calculator produces a BTU and tonnage planning range; Abraham AC should still confirm final sizing with an in-home load review before replacement.

Calculator Inputs

Estimated BTU = conditioned square feet x Florida load factor x ceiling, insulation, sun, and window multipliers, plus extra occupant load.

AC Size / BTU Calculator for Broward County Homes FAQs

Is this the same as a Manual J calculation?

No. It is a Manual-J-lite planning tool. A final replacement decision should use an in-home load review that checks the home, ducts, windows, insulation, and humidity load.

Why can an oversized AC be a problem in Florida?

An oversized AC can satisfy the thermostat before it removes enough moisture, which can leave rooms cool but sticky.

Can I size a new AC from the old model number?

The old tonnage is useful context, but it can repeat a past sizing mistake. Home changes, duct condition, windows, and insulation should be reviewed.
