Affiliate disclosure

Last updated: May 14, 2026

Splitsizer is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com. As an Amazon Associate we earn from qualifying purchases.

When a product link on this site goes to Amazon, the URL may include our affiliate tag. If you make a qualifying purchase, Amazon may pay us a small commission. This costs you nothing extra.

How this affects our recommendations

The sizing calculator is not a retailer checkout flow. It returns a BTU range and standard size class first. Product links, when present, are secondary to that sizing guidance.

We do not accept payment, free product, or promotional consideration from any heat-pump or mini-split manufacturer in exchange for placement or favorable mention.

Installer quote requests

The current calculator does not ask for your contact information. If Splitsizer adds installer quote requests later, the form will explain what information is shared, who it is shared with, and how Splitsizer is paid before you submit it.
