Paradigm Packaging Chiller Replacement
Saddle Brook, New JERSEY

An existing 20-year old 170-ton chiller was no longer reliable and breaking down on a weekly basis. Armistead Mechanical, Inc. Services installed a new Carrier AquaSnap chiller on a Thursday and had the plant up and running and ready by 7 a.m. on Monday morning.

Mount Saint Mary College
President’s Villa
Newburgh, New YORK

Armistead Mechanical Services completed this design build project for the college president’s office known as The Villa. A barely functioning system was replaced with a state-of-the-art Carrier AquaSnap high efficiency chiller. Not only was the system up and working in record time, we made sure the area surrounding the unit was neat and landscaped.

A new high efficiency chiller was installed along with a dry-cooler. New controls were installed to interface with the existing system to provide smooth integration of the new equipment.

Energy Benchmarks

As a member of the United States Green Building Council and an ENERGY STAR Partner, Armistead Mechanical, Inc. Services can assist with “Green” projects, energy performance, energy cost reduction and providing better indoor air quality and optimal thermal comfort environments.

Thirty percent of the controllable costs of operating a building are energy-related. Building owners and managers need to successfully balance energy savings with occupant comfort. Armistead Mechanical, Inc. Services can assist you in developing an efficient system design as well as help you in lowering your energy and operating costs and increasing your ENERGY STAR rating. Building managers and owners need to rely on their HVACR contractor partner to help reduce energy consumption and cost, improve the quality of a building’s indoor environment, and proactively offer solutions to help them be more successful.

Call us to arrange for an energy benchmark for your building. Using resources and methodologies developed by the Environmental Protection Agency (EPA) and the Mechanical Service Contractors of America (MSCA), we assess your building using an extensive diagnostic process to ensure optimal performance and provide solutions at every stage of your building’s lifecycle.



Armistead is environmentally conscious and committed to sustainable practices in the mechanical contracting industry. We promote the importance of “green initiatives” for plumbing, heating and air conditioning systems and the impact they can have on buildings and the people who inhabit them. As a company, we do our part to recycle and evaluate how we can reduce waste on a day-to-day basis. Both Armistead Mechanical, Inc. and Armistead Mechanical, Inc. Services, Inc. have LEED AP’s on staff and are active in promoting green building practices.
