Unnecessary Refrigerant Recharge
One of the most common HVAC scams: charging for refrigerant when your system actually doesn't need it — or has a leak that recharging won't fix.
How This Scam Works
A technician (sometimes legitimate, sometimes not) tells you your system is "low on refrigerant" and needs a recharge. They may charge $150–$500. The catch: sealed AC systems don't consume refrigerant — if refrigerant is low, there is a leak. Recharging without finding and fixing the leak is throwing money away; the refrigerant will escape again within months. Some technicians actually remove refrigerant to create the "low" reading.
Warning Signs
- Refrigerant was added during your last visit and it's "low" again within 1–2 years
- Technician recommends recharge but doesn't mention finding or fixing a leak
- No leak detection performed before adding refrigerant
- Can't show you the gauge readings or explain which refrigerant type your system uses
- Quote for refrigerant is vague ("top it off") with no quantity specified
What To Do Instead
Any refrigerant add should be accompanied by a leak test. Ask specifically: "Where is the refrigerant going?" A legitimate tech will look for the source. Minor leaks can be repaired; significant leaks may indicate the system needs replacement. Get a second opinion before approving refrigerant adds over $200.
