If your building a new home the key to getting an air conditioning system to work properly is to have a real professional size the equipment properly and install a ducting system that delivers the right quantity of air to each room of the house. Each room must also have a return-air duct inlet that vacuums hot air from the ceiling and returns this air to the central system to be cooled once more.  Or if  you already  have an exisiting unit and need help with it call Premier Air Colorado at 303-993-9060 and visit our website at www.premieraircolorado.com
