Changeover from Air Conditioning to Heat

Facilities Services personnel change over building on 2 pipe systems from air conditioning to heating each fall. Due to the nature of the equipment installed throughout the campus, buildings must be changed over separately. Facilities Services performs the changeover on the basis of priorities established 1) to maintain required temperatures to protect equipment and research in progress, and 2) to serve the greatest number of individuals and activities.

Heating changeover may not begin until outside low temperatures have dropped below at least 50 degrees F for a minimum of three consecutive days.

Consideration is also given to temperature projections. The wide swings in temperature during the fall have made this policy necessary. Special problems or hardships with the policy should be discussed with the .
