Intry.
Know what the number means.
The decision engine for HVAC and electrical work. Get the number. Know what it means. Know what to do next.
One answer opens the next question.
A technician doesn’t finish a job with a single calculation. Intry connects the decisions: size the wire, check the voltage drop, choose the conduit, and lay out the bends. Or identify a unit, check the charge, and work through a changeout.
The tools are free, with no login or paywall. Save the readings together and hand the job to your AI agent to take it further.
Sources you can trace.
Results cite the relevant code, standard, or manufacturer document. Intry’s own automated checks re-derive calculator values on each build.
