No form. No signup. Nothing collected. Tap a symptom, answer a few taps, and get a plain-English next step — a safe check you can do yourself, a pro to call soon, or a stop-now emergency.
Stop first if any of these are true
Smell gas, hear a carbon monoxide alarm, or see sparking, smoke, or a burning smell? Don’t work through this tool — jump straight to the emergency step.
The lines this tool never crosses. It will never ask you to touch gauges, handle refrigerant, open anything inside the unit, open the electrical panel beyond resetting a breaker, or bypass a safety switch. If a fix needs any of those, the tool tells you to call a pro instead — that’s the point.
