Common HVAC Scams

  • The $25 tune-up bait-and-switch — low price gets them in the door, then scare tactics
  • Fake cracked heat exchanger — most common scam in the industry
  • Refrigerant leak fraud — claiming leaks that don't exist
  • Oversized system recommendations — selling bigger than needed for higher commission
  • No load calculation — guessing at system size instead of calculating

How to Protect Yourself

Always get a second opinion on major repairs. Ask for photo documentation. Verify claims with a camera inspection. Request a Manual J load calculation before any replacement. Check CSLB license status online.
