How to keep your walk-in operating efficiently.

* Close door when not in use. Do not block or prop door open for extended periods of time. Make sure door is closed at all times except when entering and exiting the walk-in.
* Periodically, minimum of twice a year, clean evaporator and condensing coil. If located outside, the coils should be cleaned more often.
* Make sure fan motors are running at optimum speed.
* Clean fan blades to reduce drag.
* Make sure there is nothing stacked around the coil to restrict airflow.
* Occasionally have service technician check all electrical connections to make sure they are good and tight. Loose wires could cause high amperage, which will cause your unit to use more energy.
* Check for damage or decay in the insulation on suction lines between condensing unit and evaporator coil. Replace as needed.
* Check door sweep for tears and make sure sealing properly.
* Hinges should be lubricated once a year to keep closing properly.
* Make sure the lights are off when exiting the walk-in. Lights produce heat, which will cause your unit to run more to hold its optimal temperature.
* On outside condensing units, maintain clear and adequate airflow. For example, do not allow trash or weeds to accumulate around walk-in.
* Do not pile anything on top of the walk-in. This could cause damage to the ceiling panels.
* Periodically, check gaskets between panels to make sure they are not cracked or weathered. If so, check with your local health codes for the correct procedure to follow as far as repair and replacement.
