About
Every free HVAC load calculator I could find makes you pick one of five climate regions, which can put you 20°F off your real design condition. This one resolves your ZIP code to published 99%/1% design temperatures and tells you how closely it matched. Eight inputs, whole-house heating and cooling BTU plus tonnage. No account, no email gate. Same engine as the iOS/Android app, checked by an automated parity test. Block load only, and it says so.
AI Summary
The HVAC Load Calculator provides accurate heating and cooling load calculations based on specific ZIP codes, utilizing published design temperatures. It requires eight inputs for whole-house BTU and tonnage calculations, with no account or email required for access.

A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
