Affiliate disclosure

Last updated: May 19, 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

Splitsizer may also earn money from installer quote requests. If you submit the optional quote form, your project details may be sent to up to 3 local installers serving your ZIP code. Installers may pay Splitsizer per qualified lead, per booked appointment, or through a fixed local sponsorship arrangement.

The quote form is separate from the Amazon product links. You can use the sizing calculator without submitting contact information.
