COVID-19 Update:

To protect the health of our staff and our customers, Efficiency Vermont offices are closed to the public. We have cautiously begun scheduling project related site visits when required. You can find more information on our safety protocols here.

We know that you need support in reducing energy costs now more than ever, and we will continue to launch new offers and programs over the course of the summer. In the mean time, our customer support team is available to help you remotely. Contact us at (888) 921-5990 or

Six maintenance tips

  • Clean cooling coils several times a year

  • Shade outdoor coils from the sun and allow air to circulate around them

  • Make sure doors on freezers, refrigerators, and display cases seal tightly

  • Check door gaskets and auto-closers, and repair or replace if they are damaged or in poor condition

  • Have units serviced regularly to clean condensers and evaporators, and to check operation of fans and defrost systems

  • In refrigerated cases, replace T12 fluorescent lighting with LEDs—they generate less heat, easing the cooling demands on refrigerated equipment

Six refrigeration upgrades

  • If you have door heaters, add humidity-based heater controls so they don’t run continuously

  • 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

  • When buying a new compressor, look for energy-efficient discus or scrolling models—both use less energy than standard compressors and can last up to 33% longer

  • Choose ENERGY STAR® certified commercial reach-in units with solid or glass doors—and talk to us about financing options
