• •  In addition to working at homes and office buildings, HVAC damper technicians can routinely find high-paying jobs at places like airports and large manufacturing plants.

HVAC motorized dampers are not very sexy but are very useful. For example, when installed in a building's ventilation system, air conditioning dampers help to cool down occupied areas while shutting off airflow to unconditioned spaces. This type of HVAC damper system keeps people comfortable while lowering energy bills.

Damper manufacturers have upgraded HVAC damper parts in recent years to incorporate sophisticated circuitry that allows workers to control HVAC dampers remotely, reducing the need for "on-site" temperature adjustments.

In the past, HVAC damper systems were found primarily in commercial and industrial applications. Industrial HVAC dampers were necessary to control temperatures in sensitive locations such as computer rooms while ventilating large areas at the same time, such as warehouse areas. But now HVAC damper technology is becoming very popular in residential applications-for the following reasons:

1. Fully-automated HVAC motorized dampers leave the "thinking" to a specialized control system.

2. Building occupants don't have to continually adjust thermostats to maintain comfortable temperature and humidity levels.

3. The cost of installing a system of central air dampers, for example, will pay for itself in money saved from lower air conditioning electrical usage.

Turn to professionals for expert HVAC damper installation

Professional installation of HVAC dampers using proper HVAC damper parts is critical. Many qualified professionals list dampers for HVAC systems as part of their services.

I recommend: You can't discuss dampers without discussing zoning systems. Whether you need an air conditioning damper for your home or industrial HVAC damper for your business, find the professionals who can help you with all of your needs. Professional organizations like the Air Conditioning Contractors of America (ACCA) can recommend residential HVAC contractors and the Sheet Metal and Air Conditioning Contractors National Association (SMACNA) can recommend commercial and industrial HVAC mechanical contractors.

Realize that a damper manufacturer and zoning equipment manufacturer are two of a kind

The very 'guts' of a residential or commercial zoning system are the HVAC dampers. You can't discuss the dampers without discussing zoning and vice-versa.

I recommend: Visit websites of companies such as Jackson Systems and Arzel Zoning to find out about the latest HVAC damper system technology. These are the two leading dampers/zone system manufacturers in the HVAC trade.

Get useful tips on HVAC damper installation if you plan to do it yourself

Although HVAC damper installation, such as central air dampers and air conditioning dampers should be handled by trained professionals, there are outlets for do-it-yourselfers who want to tackle the job head-on and save labor costs.

I recommend: Visit the websites of some of leading damper manufacturers such as RetroZone Inc., which publish instructional guides for zone installations. Honeywell Zone Controls is a leading name in indoor comfort and is also another good source of information.

• •  Zoning systems with automated HVAC dampers are becoming a necessity today with issues over indoor air quality, HVAC system efficiency, comfort, and energy costs. Take the time to research the products you need for your home or business.
• •  The best method of installing industrial HVAC dampers or simple residential air conditioning dampers is to call a professional, licensed HVAC contractor. If you are intent on doing it yourself, learn as much as you can from damper manufacturers.

HVAC dampers are a simple, yet essential, part of the HVAC system. Much like the damper in your chimney, HVAC dampers serve to either shut off or allow air flow as it is desired and help to maintain comfortable temperatures for people and, in some cases, equipment. Office buildings may have a building-wide HVAC system or smaller climate-controlled areas for each office client. Make sure you understand your landlord's jargon — or the HVAC repairman's working vocabulary — by studying the following key terms.

HVAC

HVAC stands for Heating, Ventilation and Air Conditioning. HVAC is basically the climate-control system in a building or part of a building. Some offices buildings, for example, offer separate HVAC controls in each office.

I recommend: Green Ideas provides a definition of HVAC.

Damper

HVAC dampers are small discs that fit into the ducts of the HVAC system and can be rotated to either allow or impede air flow through any specific duct and, thus, to any specific part of the HVAC-services area.

I recommend: Engineers Edge gives an explanation of how HVAC dampers work and illustrations of what they look like.

Zoning

When used in the context of HVAC, zoning refers to the division of a building into more than one separately climate-controlled area or zone. HVAC dampers usually are used to separate and control each of these zones.

I recommend: High Performance HVAC gives an explanation of how zoning systems work.

Thermostat

The thermostat is the most basic 'brain unit' of your HVAC unit. It's the thermostat that activates the unit to either heat or cool at appropriate temperatures, and the thermostat may also control the HVAC dampers.

I recommend: DW Optimum HVAC Services explains how the thermostat activates your HVAC unit.

SEER, or seasonal efficiency energy ratio

The SEER, or seasonal efficiency energy ratio, is a measure of how effectively your HVAC damper system heats or cools the service area per dollar spent.

I recommend: The Anytyme heating and HVAC glossary gives detailed information on the SEER.

Ductless system

Most HVAC systems force warm or cool air through a series of ducts in the ceiling. Ductless systems, however, use a ceiling or wall-mounted blower to control local temperature. Dampers are still used to control airflow, much as the damper in a residential chimney.

I recommend: The Air Conditioning, Heating and Refrigeration Institute offers a detailed explanation of how a ductless HVAC system works.
