  • "I have worked with EIP on many projects over the last 18 years, and it has truly been a pleasure. They are always willing to go the extra mile and possess extensive knowledge of the products they represent.  They continually strive to satisfy the customer and provide exceptional service. There are very few rep firms that deliver the way EIP does."

  • "As a project engineer responsible for the design, construction, and operation of HVAC systems for multifunction buildings and state of the art research facilities, I have had the distinct pleasure of working with EIP for the past 35 years. They have always provided exceptional service and prompt support for an excellent line of products. I would highly recommend EIP, their product line, and dedicated staff."

  • "The customer service offered by e.i.p. is above and beyond their competitors. Whether it is technical support for unusual or unique applications, job site visits to determine the best installation practices, or improving delivery times to meet tight schedules, we can always count on e.i.p. We always get prompt, professional, friendly service. e.i.p. is more like a partner than a vendor."

  • "My experience with EIP has been phenomenal; they are always ready to be there, by our side, to get the job done. This involves jobs that have just one BTU meter or AFMS to jobs that have 100 of each.  Both projects receive the same attention. Thank you EIP for years of partnership!"
