WHY FREE? AeroSize is part of the HALOCORE app ecosystem. We believe professional HVAC tools shouldn't cost $50/month. Every feature is free, forever. Supported by optional non-intrusive ads.

Whether you're a solo technician doing residential installs, a contractor bidding jobs, or an engineering student learning load calculations — AeroSize is the tool you've been looking for.
