If your refrigeration column isn’t cooling and you suspect a refrigerant leak, it’s worth understanding upfront: this isn’t a DIY-appropriate repair, and in most cases, it’s not legally something a homeowner can do themselves.
Why Refrigerant Work Is Regulated
Under EPA Section 608 of the Clean Air Act, handling refrigerant requires certification, specifically because these substances are regulated for environmental and safety reasons.
The Physical Risks
Refrigerant exposure can cause frostbite on contact and respiratory irritation if inhaled in an enclosed space. The sealed system also operates under significant pressure.
How to Tell If It’s a Sealed-System Issue
A compressor that runs constantly without cooling effectively, unusual hissing, or oily residue near refrigerant lines can indicate a sealed-system problem — but confirming it requires specialized pressure-testing equipment.
What to Do Instead
Book a diagnostic with an EPA-certified technician. Visit our refrigerator repair page to get started.
Not Confident Doing This Yourself?
A factory-trained technician can diagnose and fix it safely, usually same-day.
