Hands-on in New York City · Online in the app
Learn it in the app. Then work the equipment on the roof.
Commercial air conditioning and refrigeration, and the two things that turn a reading into an answer: the pressure enthalpy chart and the psychrometrics. Three Saturdays on real equipment, with an instructor beside you.

On the equipment
What you walk out able to do
Install and service commercial equipment
Light commercial air conditioning and refrigeration systems, the components inside them, and what to do when one stops.
Prove the system is doing what it should
The refrigeration cycle as numbers you can check: pressure enthalpy for capacity and efficiency, psychrometrics for the air going through it.

The equipment a business cannot do without
A walk-in that fails is a store losing stock, and a rooftop unit is somebody’s whole shop. This is the plant they call about first.
Training a crew
Group pricing, invoicing and purchase orders, and an activity report for every seat.
