Holy Spirit Catholic Church

We designed and installed an HVAC system and chiller plant as part of a church expansion, within a stringent timeframe.

Value Delivered

Based on our strong relationship with Holy Spirit Catholic Church for more than 15 years, they chose EMCOR Services Aircond to design and install their new HVAC system. 

Because their faculty and students were returning to school in just a few months, we were able to fast-track our services. We began construction of the chiller plant in early spring, and renovation of the preschool the day after school ended for summer break.

We collaborated with the project’s architect/engineer and general contractor to help ensure completion on schedule, and within budget.

Our solution supplies continuous fresh air to the buildings, serving to enhance overall air quality. The four-pipe system also provides dehumidification in areas of high occupancy to help increase occupant comfort.

Client Objectives

Holy Spirit Catholic Church was building a new, multi-level facility to meet the needs of their growing congregation. They wanted a new HVAC system that would serve the expansion and two existing buildings, improve indoor air quality, and be completed within a fixed several-month timeframe.


We installed a chiller plant to accommodate the newly-built facility, existing sanctuary, and preschool. The installations in the original buildings were possible because the core of this newly-installed HVAC system was a centralized chilled/hot water plant with a network of piping and air handling units. 

The HVAC control system monitors the indoor temperature from many points throughout the facility. Our solution included:

  • Modular chiller
  • Two boilers
  • Three cooling towers
  • Eight pumps
  • 10 air handling units
  • 10 fan coil units
  • More than 20 variable air volume boxes
  • Exhaust fans
  • Piping
  • Ductwork
  • Insulation
  • HVAC controls
