In order to better serve our clients, we have developed Hayes University. Hayes University is an ongoing educational video web series that focuses on a variety of HVAC, boiler, plumbing and related mechanical system topics. The intention of these videos is to help provide our clients with a better understanding of how their equipment operates, what needs to be done to maintain these systems plus provide general information that will help clients make educated decisions. In addition to the web series, we will begin hosting online and in-person classes to help further educate our clients.

Air Cooled Chiller Replacement Project

In this session of Hayes University we review the replacement process of two 250 ton air cooled chillers.

We review the steps we took to analyze their equipment and the entire replacement process from start to finish!

High Efficiency Condensing Boiler Installation

In this session of Hayes University we review the installation process of high efficiency condensing boilers. This client had two large vintage boilers, which given their age were in relatively good condition. So rather than replacing the entire boiler room, we removed one boiler, installed two smaller high efficiency condensing boilers and left one old boiler as an emergency backup. This allowed our client to maximize their system efficiency, while reducing the overall project cost.
