Privacy policy

HVAC Cost Lab calculators run in your browser and do not require an account or email address. We do not sell project details to contractors.

Analytics and advertising

Hosting, analytics, security, and advertising providers may process device, browser, page-view, approximate location, cookie, or similar technical data according to their own policies. Google AdSense may use cookies or other identifiers to measure and personalize advertising where permitted.

Your choices

You may limit cookies through browser settings and applicable consent controls. Blocking some technology may change analytics or advertising behavior but does not prevent use of the core calculators.

Data you enter

Calculator inputs are used to display results in the current browser session. The site does not intentionally collect those inputs as a contractor lead.

Contact and updates

This policy may be updated when services or legal requirements change. The effective date will be revised for material changes.
