An "air balance" is a useful process for measuring the performance of a simple or complex hvac system, and for providing the occupants with a comfortably conditioned space.
There are two types of Air Balance - Comfort Balance and AABC Certified Air Balance
A "comfort balance" is simply checking to see whether the room feels comfortably conditioned. It may be as easy as walking from room to room, holding a hand up to the ceiling to see if sufficient air is coming out of the registers, and asking the occupants if they are comfortable. If they are not, our journey starts to discover how to resolve the HVAC problems associated with the situation. It may involve adjusting/moving registers, installing restrictors/dampers after the fact, or just insuring the air doesn't blow directly on an occupant. Many occupant complaints are associated with air circulation: too much and too little.
Other type of Air Balance is AABC Certified Air Balance. The purpose of this type is to insure all components of the hvac (heating, ventilating, air conditioning) system are working in harmony, at their optimum performance, providing total occupant comfort.
