Once the blueprints are complete, we will create a map of the new HVAC, i.e., heating, ventilation and air conditioning, system. With the help of a reputable HVAC company, we will determine the correct positioning of the air ducts and registers throughout your new home by calculating the transmission heat loss through windows, doors, walls, etc. Our end goal for this phase is for your new home to have its optimal temperatures and temperature control systems, in order to promote your maximum comfort and most efficient energy use.
