Newsletter from HVAC Intelligence Network
HVAC Signal
High-signal HVAC news for contractors.
TLDR-style packaging — refrigerant rules, safety, shop economics, commercial/controls, and field tech. Not generic AI sludge.
We read the docket, the trade press, and the manufacturer notes so a shop owner does not have to. Each issue is a short brief: what changed, why it matters on a truck or a bid, what to do this week. The first issue goes out Monday, September 14, 2026 at 9:00 AM ET. After that, Monday / Wednesday / Friday. A human must APPROVE every send. This site does not auto-send email.
Past issues live on hvacsignal.ai once they have gone out. The first one lands Monday, September 14, 2026 · 9:00 AM ET.
