Frequently Asked Questions
My walk-in cooler is not cold. What should I do?
Keep the door closed, check that the condenser is not blocked, and call us at (703) 468-1339. Move critical product to backup storage if temperatures continue to rise.
How often should refrigeration equipment be serviced?
Most commercial refrigeration should be serviced quarterly, and coils in kitchens may need more frequent cleaning.
Can you add a temperature alarm to my walk-in?
Yes. We install temperature monitoring and alarms that alert you before product is at risk, and we can integrate them with existing building systems.
