Born from a simple realization — the hardworking trades were being left behind while technology moved forward without them.
AirIQ was built to change that. AI-powered diagnostics built for the tech in the field, because the trade deserves better.
Four ways to diagnose — pick the one that matches what you're seeing on the job.

No. AirIQ works with what you already carry — your phone, your multimeter, your manifold gauges. No smart probes, no tablets, no $500+ hardware kits required. Readings are optional throughout — enter them if you have them, skip them if you don't.
Every diagnosis includes a confidence score. Low-confidence results get flagged with specific verification guidance before you act on them. AirIQ is a diagnostic assistant, not a replacement for field judgment — it's designed to speed up the troubleshooting path, not bypass it. If something doesn't match what you're seeing, tap Ask AirIQ AI to talk it through.
Each plan includes a specific number of seats (1 for Solo, 3 for Crew, 8 for Company, 15 for Enterprise). One tech per seat. Account sharing isn't supported — sessions are tracked, and sharing a login will sign the previous device out.
After 3 days, your card is automatically charged the monthly rate for the plan you selected. You can cancel anytime before the trial ends and won't be charged.
Yes. No contracts, no cancellation fees. Cancel from within the app — your subscription ends at the close of your current billing period, and you keep full access until then.
Your job logs are private to your organization. Other shops can't see your data, and we don't sell it.
AirIQ is built for field conditions. Hardcoded fault databases work instantly with no AI call needed. AI-powered features require internet but include automatic retry on network failures. For basement calls or rooftop work with no signal, use the hardcoded databases first — AI steps in once you're back on signal.
AirIQ is an independent diagnostic tool. We are not affiliated with or endorsed by any HVAC manufacturer, thermostat brand, or parts supplier. All brand names are used solely for identification purposes.
Every plan includes all diagnostic paths, HVAC Tools, job history, and 100 AI calls per tech per week.
