What's Causing Condensation In Your Walk-In Freezer Or Cooler?

A walk-in unit is designed to be air tight to regulate the temperatures within the cooler or freezer. If your normal regulated temperatures seem off, or if you begin to see condensation or ice buildup within the walk-in units it is a sign that something within the system is off. An air tight walk-in cooler or freezer should mean that no frost, ice, or any other type of condensation build-up should be possible.


When you call in a service call, the technician that shows up may start by measuring the humidity within the walk-in. Temperature changes within the unit will lead to humidity - and can often times help pinpoint what the issue may be. Often times it can be something as simple as a strip curtain or door sweep, or a door seal or gasket that is damaged. This little damage may not even be noticeable while going in and out of the walk-in unit, however just the littlest amount of breach in the air seal can lead to moisture buildup within the unit. If any damage to these seals or strips is found it is recommended to replace them as easily as possible and this will likely be the fix to the condensation issues.


A technician may also check outside the unit for any visible signs of damage to the exterior, or any signs of air blockage that could lead to damage to the exterior walls. A box falling may dent the walls enough to cause damage, and even the slightest hairline crack can cause air to get into the walk-in unit and begin causing problems. If the walls around a unit are not spaced out enough from the walk-in and the wall, or if storage around the unit is too packed in, it can cause poor air flow and lead to a build up of condensation in those poor air flow areas. Any wall that has condensation build up risks mold and mildew buildup, which can speed and cause significant damage to your building. 


Through regular routine check ups over your walk-in cooler or freezer you can likely spot any condensation and other issues that may cause long-term damage to your building and walk-in unit. By catching these problems early you may wind up saving yourself a significant amount of money as opposed to the issue getting worse and causing more damage to the equipment, leading to heavy repair or replacement fees.
