High Velocity Air Conditioners

High velocity air conditioners work by delivering air into a room at a high velocity (roughly two feet per second). This creates air currents that circulate cooler air throughout the room or entire house.

The high velocity systems have certain advantages and disadvantages over the conventional forced air system. For example, the conventional systems moves air slowly. You really don't feel the circulation and there can be dead spaces in rooms if vents were not placed properly. High velocity systems places vents in more locations; thus, there is a more consistent airflow and temperature throughout the house. However, since conventional systems use larger ducts, more air passes through and they are silent. The high velocity systems use much smaller tubes to circulate air and are nosier. Conventional systems are also easier on your pocket, as tend to last longer because of the metal ductwork, etc. High velocity tubing deteriorates more often than metal ducts and tubing causes stress on the mechanical components of the unit.

On the plus side, conventional systems are more visible in the home than the high velocity. Conventional systems require more space because of the larger vents, and every room needs a supply and return. The high velocity unit requires much less space and can be set up in one area for the supply and return requirements. Also, the high velocity system is less expensive than the conventional one.

Finally, keep in mind that central cooling systems are not easy to install. There is generally a problem with any installation. Any errors in installation can cause major problems and a major impact on your electric bill. Make sure you get plenty of bids and pick a contractor that you have faith in. The contractor should be experienced and offer you references to check out the work that has been done.
