Laird and Son offer two types of attic air conditioning:
* A low velocity air conditioning system utilises a condenser outside and an air handler in the attic. We install conventional metal ductwork and insulate to prevent condensation. We install 4 by 10 inch supply air vents in each room with an 11 by 14 inch return air in the hallway of the top floor. This system is ideal for bungalows without ductwork and also in smaller two story homes. In cooling the upper level the lower level gets cooled by the down flow of cold air. These systems are a good value for those with limited budgets.
* A High Velocity air conditioning system uses high velocity air distributed through small flexible tubes. We install 2 inch round outlets in each room with a return air on the top level. This system also utilises a condenser on the outside and an air handler in the attic. The indoor components are smaller and the entire system is sound attenuated preventing mechanical and air noise. The air enters the living space with enough velocity to aspirate with the room air, eliminating hot and cold spots. We install the Unico system, which also removes 30% more humidity than standard air conditioning systems. This type of installation tends to be for larger homes and for noise sensitive situations.
