Rooftop ac units installed on metal building roof.

This guide does not address roof penetrations. When you are considering putting an air conditioner on your roof the system that you are looking at is a packaged unit. Because everything is together and on the roof ducts can be run straight down from the unit and throughout the building. It can also be mounted on a slab at ground level.

This is more often the best placement for private homes. Roof curbs should be supplied by the hvac manufac turer to the general contractor or building manufacturer and installed by an experienced erector. Unfortunately an improperly placed and installed packaged rooftop unit can lead to roof damage including punctured membranes and sagging that could lead to ponding water and leaks. This means that the condenser and the fan are all in one unit and not split apart and connected by hoses or pipes.

Mechanical contractors should not be asked to supply or install roof curbs for roo fi ng systems. New steel angles were added to support the metal decking at all new openings and below all edges of the new rooftop unit. It was also important to adequately fasten the new unit to the roof structure below. Rooftop units are an extremely common setup in hvac systems for commercial buildings due to their ease of installation good energy efficiency and ability to provide heating and cooling in one unit.

This combination heating and air conditioning unit can be mounted on the roof especially in the case of businesses with flat roofs. Instructions supplied with the unit curb.
