They even check factors to take care of while manufacturing an HVAC system like the roofs and walls of the place, exposed to the direct sunrays, absorb considerably high heat. For instance, the walls exposed to north and south gain the maximum amount of heat while those exposed to the west gain the least. The heat stored in the walls during the daytime is released during the night making the environment hot. Nevertheless, proper insulation of the walls will help reduce the heat gained.
