What Our Customers Are Saying

Pearl S. Buck International has been using Diversified Refrigeration for all aspects of our HVAC needs for over 15 years. The technicians are professional and knowledgeable and their maintenance program keeps or systems running efficiently and effectively. We look forward to a continued relationship for years to come.

Reliable prompt, courteous and efficient service – some people think these values are gone from the work place but we at Quakertown National Bank (QNB) have been working with Diversified Refrigeration for years and I can tell you that they are not. Their service department, has consistently come through for us providing prompt reliable repairs and replacement of parts.

Working with contractors to maintain capital equipment can be a challenge, especially in a 24/7 healthcare facility like the Madlyn and Leonard Abramson Center for Jewish Life. As director of Plant Operations I commend you on your company’s work ethics and communication while in our facility.
