Frequently Asked Questions
My freezer room is icing up — is that a refrigerant problem?
Not always. Heavy ice is most often a defrost system or airflow issue. We diagnose before regassing to avoid repeat failures.
Can you repair a freezer room without emptying it?
In most cases yes. We work around stored product and use temporary containment to protect stock during the repair.
How do you stop the ice coming back?
We correct the root cause — defrost timing, airflow or refrigerant charge — not just the visible ice.
