A survey by Emerson Climate Technologies shows that many homeowners are unfamiliar with the SEER rating system and are neglecting professional inspection and service for their central air conditioning system. The 2004 Home Air Conditioning Test revealed:

  • More than three out of four Americans (77%) with central air conditioning say they have never heard of the federally mandated SEER rating.

  • More than a third of homeowners indicate they did not have their home's central air conditioner inspected or serviced by a professional contractor in the past year, and the same percentage do not plan to this year.

  • One-third of homeowners would consider purchasing a high-efficiency two-stage air conditioner that provides more even temperature and humidity control.

  • 43% of respondents would consider installing a programmable thermostat.

  • 49% with central air conditioning are likely to consider installing or using more ceiling fans.

The telephone survey of 427 U.S. homeowners with central air conditioning has a sampling error of plus or minus five percentage points.
