HVAC Brief: Safe Disposal Questions Start at the End of the Equipment Life

The useful part is not the headline. It is what a candidate should do differently before paying for another exam date, class, or practice product.

What changed for the reader

• The source is useful because it keeps connecting appliance disposal, final recovery, and responsibility for refrigerant removal tied to real field language instead of abstract test wording.
• The common exam trap is answering as if the system is still in normal service.
• Candidates should turn the topic into a short timed drill, then explain the rule cue before checking the answer.

For disposal practice, write who has possession and when refrigerant must be recovered.
