Affiliate disclosure
Clear and conspicuous — required reading, not fine print.
Who we are
The HVAC Stack is an independent occupation-stack comparison site for HVAC technicians. We are not a manufacturer, distributor, certifying body, or contractor. Brand names on this site refer to third-party products and training we research or link to.
How links work
When affiliate programs are active, product and course links may use tracking URLs from networks such as Amazon Associates, Impact, PartnerStack, or brand-direct partner programs. Commissions help pay for hosting, research time, and site maintenance.
We do not invent commission rates, cookie windows, or approval odds in editorial copy. Rates belong in private tracking after dashboard verification.
Editorial independence
Affiliate relationships may influence which products we can link, but they do not excuse fake winners, invented lab tests, or “#1 rated” badges without methodology. Incomplete research pages stay marked Researching — picks coming.

What we won’t do
- Teach unlicensed HVAC work, refrigerant workarounds, or DIY A2L charging procedures
- Present EPA 608 course pages as legal advice or proof you are certified
- Give insurance coverage advice (category links only, when present)
- Pretend to be an independent lab we are not
Third-party sites
