Ductless Room Planning

Mini-Split Sizing and Cost Calculator

What size mini split do I need for one hot room?

A single-room mini split estimate starts with room square footage, sun exposure, insulation, ceiling height, and whether the space is a garage, lanai, bedroom, or addition. The result is a BTU planning range and a quote-safe installation complexity range.

Calculator Inputs

Estimated mini-split BTU = room square feet x Florida room load factor x exposure and insulation multipliers.

Mini-Split Sizing and Cost Calculator FAQs

Can a mini split cool a garage in Florida?

Often yes, but garage insulation, door exposure, electrical capacity, and use pattern matter.

Is one mini split enough for an addition?

It can be enough for a single zone if the BTU size and placement match the space.

Does this calculator quote installation price?

No. It gives a planning range and flags scope factors that need an on-site review.
