Since its inception in 1910, St. Patrick Catholic
Church (St. Patrick’s) in Lake Forest, Illinois, has been
a place for the community to gather. Over time, as the
Lake Forest community grew, the 3,900-square-foot
building underwent several structural renovations to
accommodate new members and guests.
In 2016, after tolerating many years without air conditioning,
the church decided to install a new HVAC system in
an effort to make the space even more comfortable
for the large congregation. It turned to Variable
Refrigerant Flow (VRF) technology from Mitsubishi
Electric Cooling & Heating (Mitsubishi Electric).
