MEEA Co-Authors U.S. Department of Energy’s Improving Gas Furnace Performance: A Field and Laboratory Study at End of Life.
MEEA worked in conjunction with our Partnership for Advanced Residential Retrofit (PARR) team members to collect and analyze working furnaces that were removed from Iowa homes. The purpose of this research was to investigate the impact of age degradation and typical installation practices on the steady-state furnace efficiency. This research found that ‘typical’ field installation practices result in less than optimal steady state efficiency and that normal furnace equipment age degradation does not impact steady state efficiency. This research is important to MEEA’s HVAC SAVE program because it supports the principal that improved installation practices, similar to what is taught in the HVAC SAVE program, can improve a furnace’s in field operating efficiency.
