About Mini Split Size Calculator

What this site is

Mini Split Size Calculator provides beginner-friendly calculators, guides, and glossary pages focused on mini split sizing for US homeowners. All estimates use publicly available sizing guidance and are presented with clear assumptions so you can see how the numbers are reached.

Every result from a calculator on this site is an estimate and a planning starting point. These tools are not a replacement for a professional Manual J load calculation performed by a qualified HVAC professional.

What this site is not

This site does not offer professional engineering advice, installer recommendations, exact equipment selection, price claims, rebates, tax credit guidance, or product rankings. The maintainer does not hold an HVAC license or engineering degree. Content is based on publicly available sizing principles, common industry rules of thumb, and transparent assumptions — not professional certification.

Why estimates only

Accurate sizing depends on factors a website cannot measure: local climate data, insulation quality, window placement, ceiling height variation, internal heat loads, and duct conditions. A Manual J calculation accounts for all of these. An online calculator cannot. This site is honest about that limit on every calculator page.
