Smart and cool the art of air conditioning
SEGMENT 1 - Biggest opportunities for savings is in the duct system; what is wrong - what can be fixed; how people think is exact opposite to the truth.
SEGMENT 2 - Duct design good, bad and the ugly; Air handlers, good vs. bad.
SEGMENT 3 - Sources of good information; Getting the technicians to do it right; New systems that work; Ducts - different types - what works, what doesn't.
SEGMENT 4 - Getting the duct design right.

HVAC >Air Conditioning
John Proctor, with Proctor Engineering, gives an overview of the necessary step needed to ensure the proper sizing of A/C units and ducts.
Approximately 50% of the money spent on A/C systems is due to inefficiencies in the installation process. John Proctor, engineer and HVAC consultant, outlines proper A/C installation procedures and achieving optimum airflow.
