| John Proctor, P.E. (2009) | AC Sizing, Electrical Peak, and Energy Savings. Reducing the power draw of the air conditioners that cause electrical peak cannot be justified by energy savings. It is necessary for both the peak causal effect of air conditioners be understood and the high cost associated with that peak be fully valued. |

| George Peterson, P.E., Rob de Kieffer, John Proctor, P.E., Tom Downey. (1999) | An Assessment Of Technical Degradation Factors: Commercial Air Conditioners And Energy Management Systems. This Study , is the third project to examine the relative technical degradation of demand side management (DSM) measures compared to standard efficiency equipment. This project covers two major DSM measures: commercial direct expansion air conditioners (Comm. DX AC) and energy management systems (EMS). | ||

| M. Blasnik, J. Proctor, T. Downey, J. Sundal, G. Peterson. (1995) | Assessment of HVAC Installations New Homes in Nevada Power Company Service Territory. In residential air conditioning systems, dutc leakage, low duct insulation levels, and insufficient air flow across the indoor coil can result in significantly reduced efficiency. This project investigates oppertunities for enhancing the performance of AC systems and recommebds a package of moderate cost improvements leading to lower energy use and demand and greater occupant comfort. | ||

| Tom Downey, John Proctor, P.E. (2004) | CheckMe! In Southern California Edison Company’s (SCE) Territory. The CheckMe system saves energy and reduces peak load by addressing the problems of leaky duct systems, and air conditioners which are either incorrectly charged, and/or operating with low airflow. These problems are widespread. CheckMe is a one of a kind combination of in-field technician training, computer diagnostics, and immediate test verification and feedback. |

| John Proctor, P.E., Rob deKieffer, Mary O’Drain, PG&E, Amalia Klinger, PG&E. (1999) | Commercial High Efficiency Air Conditioners : Savings Persistence. Proctor Engineering Group established a time series estimate for condenser and evaporator coil fouling rates for commercial air conditioning units. This was derived from available research. Laboratory testing was used to modify the estimated fouling rates and establish a profile for coil fouling. Both high efficiency and standard efficiency coils were tested in a controlled laboratory environment and subjected to continuous fouling. The efficiency of the air conditioner was monitored at various intervals to document the effects of coil fouling on efficiency. |

| Abram Conant, Mark Moder, Joe Pira, John Proctor, P.E., Mike Gebbie (2004) | Comprehensive Diagnostic and Improvement Tools. Proctor Engineering Group, Ltd. (PEG) and Carrier-Aeroseal LLP performed an investigation of opportunities for improving air conditioning and heating system performance in existing light commercial buildings. |

| Tom Downey, John Proctor, P.E. (2001) | Evaluation of the 2000 SDG&E Residential HVAC Training Program. The 1990 Fresno Appliance Doctor Pilot Project was created to investigate the potential energy and peak savings in residential air conditioners and gas forced air furnaces. The Fresno study was targeted at Pacific Gas and Electric’s high bill complaint customers (Energy Cost Inquiry’s or ECI’s). | ||

| John Proctor, P.E., Danny Parker (2000) | Hidden Power Drains: Residential Heating and Cooling Fan Power Demand. This paper compiles power draw, airflow, and static pressure measurements of residential air handlers taken during nine separate field tests of space conditioning systems in Arizona, California, Florida, Nevada, and Canada. The field tests show that air handler power draws exceed the standard assumptions and that the interactions between airflow and cooling capacity combine to degrade overall system efficiency. The findings support conclusions from previous research in Canada that called for a systems approach to improving air handler efficiency. | ||

| Tom Downey , John Proctor, P.E. (2001) | Assessment of HVAC Installations in Long Island Lighting Power Authority’s Service Territory. Conservation Services Group (CSG) contracted with Proctor Engineering Group (PEG) to analyze data collected by CSG field personnel on air conditioner installations in Long Island Lighting Power Authority’s (LIPA) service territory. This investigation involved field testing the air conditioning units, duct systems, and building shells of a sample of homes with recently installed air conditioning systems. | ||

|||
| John Proctor, P.E. (2012) | Indoor Air Quality Application: Residential AC Filters. Field research in California residences has found that the trend for homeowners to replace lower arrestance filters with higher arrestance filters results in lower airflows, which means lower efficiencies of the furnaces, heat pumps, and air conditioners. |

| John Proctor, P.E., Tom Downey, Abram Conant, Dave Wright (2003) | Innovative Peak Load Reduction Program CheckMe!® Commercial and Residential AC Tune-Up Project. In homes and small commercial buildings, the primary cause of electrical peak is central air conditioning. The predominance of older existing air conditioners (not new ones) and their contribution to peak make ensuring highest efficiency operation a prominent priority. | ||

| John Proctor, P.E., Zinoviy Katsnelson, George Peterson, P.E., Ann Edminster (1994) |
Investigation Of Peak Electric Load Impacts of High SEER Residential HVAC Units. The objective of this study was to collect data on and analyze the performance of presently manufactured air conditioners operating at high ambient temperatures. The design parameters that affect power draw under these conditions were investigated. |

| Tom Downey, John Proctor, P.E. (1998) | Investigation Of The AC2 Air Conditioner. Pacific Gas and Electric Company (PG&E) contracted with Proctor Engineering Group (PEG) to field test residential air conditioners with evaporatively cooled condensers. The units tested are AC2 units manufactured by Refrigeration Technology Incorporated. Five sites were selected as representative of conditions in PG&E's service territory. | ||

Pacific Gas and Electric Company (PG&E) contracted with Proctor Engineering Group (PEG) to field test residential air conditioners with evaporatively cooled condensers. The units tested are AC2 units manufactured by Refrigeration Technology Incorporated. Five sites were selected as representative of conditions in PG&E's service territory. | ||

| Tom Downey, John Proctor, P.E., Michael Blasnik (1995) | Nevada Power Company New Construction HVAC Program Implementation Plan. This implementation plan is based on a study performed for Nevada Power Company (NPC), the Electric Power Research Institute (EPRI) and the Nevada State Energy Office (NSEO) and on a series of HV AC pilot studies performed for Pacific Gas & Electric (the Appliance Doctor™ projects) conducted by Proctor Engineering Group (PEG) over the course of several years. | ||
