Packaged Multizoneasaurus thrived primarily between 1960 and 1980 A.D. The habitat for this large heating and cooling beast typically consisted of rooftops in cool and temperate regions of the North American continent, where the length and severity of heating and cooling seasons are similar. Many can still be found in place today. Notably, its present-day counterparts consume far less energy, a process that took decades of evolution.
Usually, packaged multizone air handlers were installed at institutional facilities, schools, hospitals, or banks, and were selected based on their ability to provide simultaneous heating and cooling to different zones within the structure.
