Heating

Air Conditioning Services is responsible for repairing all heating system equipment within buildings on the Main and Agricultural campuses as well as off-campus buildings. Both systems which use steam from the central steam plant, and those with separate or stand-alone systems. Approximately 100 different heating systems are maintained on campus in addition to the central steam system equipment. Heating systems located in various buildings on the campus include, electric, gas fired boilers and furnaces, and hydronic hot water heating systems.

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 Vice Chancellor of Facilities Services.

Changeover from Heat to Air Conditioning

Facilities Services personnel change over building on 2 pipe systems from heat to air conditioning in the spring. 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.

Air conditioning changeover may not begin until outside temperatures have reached at least 80 degrees F for three consecutive days.
