John Proctor - Air Conditioning: Smart Solutions for Customer Comfort
John Proctor is the president of Proctor Engineering Group, Ltd. and the primary development engineer on the CheckMe! quality assurance system. John's current research projects include two new high efficiency air conditioners for hot dry climates and a low cost system for continuous monitoring of residential and small commercial system performance.
SUGGESTED READING:
  • 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.

    AC Sizing
    John Proctor, with Proctor Engineering, gives an overview of the necessary step needed to ensure the proper sizing of A/C units and ducts.

    AC Installation
    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.
