To understand the need for air conditioning ducting, one must first understand how a central air system works. First, a system of intake grilles or louvers pulls fresh air from outside into the central air conditioner. The air is then cooled and blown into an air conditioning duct system where it is distributed to various rooms and office spaces. The cool air enters the rooms through air terminal units installed at the end of each duct line which generally take the form of diffusers or grilles. This network of ducts that transport cool air from the air conditioning unit to each room is called the supply ductwork.

To regulate the air pressure in each room, some air must be removed to make way for the new cool air supply. A second set of air conditioning duct called the return ductwork, is used to remove and transport warmer air from each room back to the air conditioning unit for cooling. The air enters the return ducts through exhaust grilles or registers in each room, then travels back to the central air conditioning unit where it is cooled again for redistribution or released to the outside of the building and exchanged for fresh air.

Thermoteq Pressure ventilation system draws drier, fresher air into your home from either the roof cavity or outside. This air is then passed through a high efficiency filter and introduced introduced into your home. This process positively pressurises your home creating air circulation and forcing out the moist, stale air that causes condensation, mould & mildew.
