The best way to spend less on commercial refrigeration

Refrigeration is a major energy expense for many businesses. You can spend less on refrigeration. Focus on basic maintenance and preventing refrigerant leaks.  

Five maintenance tips for commercial refrigeration
  • Clean cooling coils several times a year
  • Shade outdoor coils from the sun
  • Check door gaskets and auto-closers. Plan to repair or replace if they are in poor condition or have damage
  • Replace T12 fluorescent lighting with LEDs. LEDs use less energy and generate less heat, easing the cooling demands on refrigerated equipment
  • Maintain a leak-tight refrigeration system, keeping refrigerant in the system where it belongs 
Prevent refrigerant leaks with these best practices

Refrigerant leaks can be a big challenge for many businesses that have a lot of commercial refrigeration. Start with these best practices to make sure you are not losing refrigerant. A system that is low on refrigerant must work harder to control temperatures, costing more to operate. Getting too low on refrigerant can even cause a system failure, leading to climbing case temperatures and even spoiled food.

Conduct thorough leak checks on a regular basis. A service technician should check for leaks every 1-2 months, based on the size of the system and the system type. Large central systems likely need to be checked more often. 

Install an automated leak detection system. Install a refrigerant leak monitoring, notification, and alarm system. This will allow you to detect leaks and repair them before they become a major problem. 

Why refrigerant leaks matter

Preventative leak detection and repair can: 

  • improve equipment reliability 
  • reduce refrigerant expenses 
  • increase energy efficiency of refrigeration equipment  
  • mitigate the environmental impact of refrigerant leaks 
Six upgrades for your refrigeration system
  • If you have door heaters, add controls so they don’t run all the time
  • Add doors to open cases or install night curtains to reduce the energy needed to cool open cases overnight
  • Use an outside air economizer to ease the demand on your compressor
  • If you’re replacing your evaporator fans, consider high-efficiency motors and controls
  • Look for energy-efficient models. These models use less energy than standard compressors and can last up to 33% longer
  • Choose ENERGY STAR® certified commercial reach-in units
