Controlled Air, Inc. recently replaced an Evapco Cooler with an Evapco closed circuit cooler. The new Evapco cooler has low fan sound, an easy-to-maintain drive system, and a swing-out motor. We also installed a new VFD one-source power control panel with an integral variable frequency fan drive. Additionally, the steel supports were replaced so that…

The Knotter office building required a complete rebuild. The front entry needed to be redesigned because they had taken over the whole building and previously there had been multiple companies within the space. The heating and cooling was a challenge because the entryway was made mostly of glass, making so traditional heating and cooling could…

55 Farmington Ave. began as a basic, but large project with a tenant fit out and rehabilitation for a state owned 12-story building. The building was being renovated for 10 state agencies to relocate. There were major time constraints on this project, which began in December, and needed to be completed by June 1. We…

The town of Greenwich requires that nothing can be viewable from the street. We found a Evapco 600 ton-cooling tower that was the same size. The new unit…

This amazing remodel included variable speed air handlers and sensors that read the room occupancy. The room sensors control the temperature and air speed, so that when the room is empty no energy is wasted. With shallow ceiling to deck space customized soffits and duct work was required to make the system work and look…

We reclaimed the R-22 per EPA guidelines and removed the old equipment. We then furnished a new high efficiency American Standard RTU with adapter curb and 100% outside…

Felner Corporation is a regular customer of ours. In this job we are replacing 20 roof top units over time. We priced out both regular efficiency and high efficiency units before beginning installation. We were able to get them a rebate on the high efficiency units of $250 per ton, making the energy efficient unit…
