To Our Valued Customers:

As our concern regarding the spread of COVID-19 and the safety of our customers, employees and the community is of utmost importance, I wanted to update you and inform you that we are monitoring the situation through our Erie Risk Management Agency and following all guidelines established by the CDC and PA Dept. of Health. That being said, Diversified Refrigeration, Inc. remains open and ready to serve you and any needs you have, yet maintaining the safety of all concerned. Any and all work needed on your HVAC&R equipment, whether it be repairs, emergencies or Preventative Maintenance inspections which can be done while buildings are empty, should be considered.

We will continue to serve you in the safest manner possible during this crisis.
