Acronym for Heating, Ventilation and Air Conditioning. Refers to equipment used to heat and cool a building. Before the TCJA, eligible properties included only rental properties, restaurant real estate and retail real estate. The two new ADS property categories will henceforth be described collectively as properties covered by the choice of real estate or trades or agricultural businesses or simply by the choice of companies.
To be eligible, HVAC costs must correspond to non-residential real property that is put into service after the date the property was first put into service.
