HVAC work is thermodynamics, diagnostics, and preventive maintenance. Swap refrigerant for data and the job description starts to look like DevOps.
Free. No spam. Built for hvac techs.

Describe symptoms, model numbers, and readings to AI for a ranked list of likely causes and tests — then verify with your gauges. Like having a senior tech on every call.
Dictate your findings; AI produces the maintenance report, the customer summary, and the recommended-repairs upsell — consistently and professionally.
Generate your pre-season tune-up campaigns, reminder emails, and review responses in an afternoon — work that used to need an agency.
HVAC techs live by preventive schedules and sensor readings. That's monitoring and observability in tech — a well-paid, high-demand specialty.
You already work with control loops, sensors, setpoints, and troubleshooting trees. Modern infrastructure teams describe their work in exactly those terms.
