Commercial Indoor Air Quality Services & Products for Dacula, Lawrenceville & the Greater Atlanta Area

Commercial Indoor Air Quality

It's easy to take the air in your building for granted until an issue arises that draws attention to it. Acceptable indoor air quality (IAQ) is much more than providing a prescribed volume of outdoor air per person. Today's building owners are concerned about maintaining and documenting IAQ; not only to avoid problems with condensate, building sickness, or noise issues, but to provide a clean and healthy working environment in the building.

Zack Hammonds A/C Heating Refrigeration, Inc is a leading Atlanta commercial HVAC contractor. We believe that good HVAC system selection and design, specification of equipment and furnishings, along with proper building operation and maintenance are the foundations of high quality indoor air. Temperature, humidity, particulate count, fresh air volume and circulation, odors are all variables of IAQ that we can monitor and control for your specific building's purpose, whether your building is a school, 5-star resort, family restaurant or hospital.

We have the expertise to ensure that all essential aspects of your system support your IAQ requirements and help your building fulfill its purpose, however specialized it may be. For a commercial HVAC contractor you can trust, Zack Hammonds is the company you should call! Our service area includes Bishop, Watkinsville, Covington, Lawrenceville, Loganville, Buford, Snellville, Atlanta, GA, and the surrounding areas.

Pollutant Sources

Pollutant Sources1

There are many sources of indoor pollution. These include combustion sources such as oil, gas, kerosene, coal, wood, and tobacco products; building materials and furnishings as diverse as deteriorated, asbestos-containing insulation, wet or damp carpet, and cabinetry of furniture made of certain pressed wood products; products for cleaning, maintenance, or personal care, central heating and cooling systems and humidification devices; and outdoor sources such as radon, pesticides, and outdoor air pollution.

The relative importance of any single source depends on how much of a given pollutant it emits and how hazardous those emissions are. In some cases, factors such as how old the source is and whether it is properly maintained are significant. For example, an improperly adjusted gas stove can emit significantly more carbon dioxide than one that is properly adjusted.

Ventilation Improvements

Another approach to lowering the concentrations of indoor air pollutants in your building is to increase the amount of outdoor air coming indoors. Most building heating and cooling systems, including forced air heating systems, mechanically bring fresh air into the building. Opening outside air increases the outdoor ventilation rate. Local bathroom or kitchen fans that exhaust outdoors remove contaminants directly from the room where the fan is located and also increase the outdoor air ventilation rate.

It is particularly important to take as many of these steps as possible while you are involved in short-term activities that can generate high levels of pollutants - for example, painting, paint stripping, or engaging in maintenance activities such as welding, soldering, or sanding.

Air Cleaners

There are many types and sizes of air cleaners on the market, ranging from relatively inexpensive table-top models to sophisticated and expensive whole-building systems. Some air cleaners are highly effective at particle removal, while others, including most table-top models, are much less so. Air cleaners are generally not designed to remove gaseous pollutants.

The effectiveness of an air cleaner depends on how well it collects pollutants from indoor air (expressed as a percentage efficiency rate) and how much air it draws through the cleaning or filtering element (expressed in cubic feet per minute). A very efficient collector with a low air circulation rate will not be effective, nor will a cleaner with a high air circulation rate but a less efficient collector. The long-term performance of any air cleaner depends on maintaining it according to the manufacturer's directions.

Another important factor in determining the effectiveness of an air cleaner is the strength of the pollutant source. Table-top air cleaners, in particular, may not remove satisfactory amounts of pollutants from strong nearby sources. People with a sensitivity to particular sources may find that air cleaners are helpful only in conjunction with concerted efforts to remove the source.
