Industrial refrigeration units come at a high price. Without the proper maintenance and care, your investment could need replaced or repaired well before it should. Here, you will learn a few steps to take between professional maintenance servicing, and what to expect during professional servicing to extend the life of your refrigeration unit and avoid costly repairs.

Inspect the Door Seals

The refrigeration unit will only work efficiently if the seals on the doors are in good condition. Inspect the seals, looking for signs of cracking, peeling, or mold growth. Oftentimes, these seals are overlooked during the cleaning process and begin to grow mold that can be unhealthy and damaging to the unit. If the seal shows any signs of wear, replace it or contact your local refrigeration expert to have it replaced for you.

Check the Drain Lines

The drain lines on your refrigeration unit must remain free of blockages so that the condensation that is produced by the unit can drain. Locate the drain line, which is usually at the base of the unit, but can sometimes be found on the back-side of the unit. Check the opening of the line to be sure it is free of blockages and that it is draining properly. If it is not draining freely, tape a straw to the end of the line and give it a good blow. This should release any blockages, but if it does not, contact a professional for repairs.

Clean the Condenser

The condenser can be found at the bottom, on the top, or on the back-side of the refrigeration unit. To examine the condenser, you must remove the cover. Look for any buildup of grease, dust, or debris. If you notice any buildup, unplug the unit, and use a soft cloth to gently wipe away as much buildup as possible. If the condenser is consumed with buildup, contact a professional to service and clean it to keep it running efficiently.

Professional Servicing

Having a professional service your refrigeration unit is a very important part of maintenance. The technician will:

  • Perform a cycling check
  • Clean the seals, coils, and drains
  • Check the refrigerant levels
  • Oil the mechanical elements
  • Inspect the wiring and compressor
  • Provide you with a list of necessary repairs

There may come a day that the repairs for the refrigeration unit are costly enough to consider replacing the unit rather than repairing it. The newer models of refrigeration units are more efficient and will be less costly to repair and maintain over the years. Talk with your local commercial refrigeration company to learn more about your options.
