The following pictures show the conditions of the current HVAC equipment at our two schools. At Concord Elementary, 9 of the 11 zones are heated and cooled by HVAC systems that were installed in either 1996 or 1997 and have already exceeded their life expectancy. At Cass Junior High, 15 of the 19 zones are heated and cooled by HVAC systems that were installed in 2002 or prior, with the vast majority at or nearing the end of their life expectancy.

Approximately 80 percent of the district’s HVAC infrastructure needs to be replaced. Following are several pictures of the school district's current HVAC systems:
