More Indoor Air Quality Products for the Atlanta Area


Everyone deserves fresh, clean air in the comfort of their own home. Unfortunately, though, studies have shown that indoor air quality can often be even more contaminated than outdoor air. Heating and cooling systems recirculate air throughout the home without actually removing contaminants or other suspended particles. Our Clean Green Comfort Systems do exactly that, using the most advanced products and technology to improve indoor air quality (IAQ) and ensure the air in your home is safe for the entire family.

Air Quality Testing

In just 30 minutes, we can deliver a snapshot of the six leading indicators of air quality. We use “Air Advice” monitors that will check the temperature, humidity, particulates, volatile organic compounds (VOCs), carbon monoxide, and carbon dioxide levels in your air. The “Air Advice” system uses a wireless connection to upload readings to their central servers and generate a detailed IAQ report. Usually, within moments a technician can share the results of your air quality analysis directly in your home.

Ventilation SystemsOutside-air-Duct-with-Fresh-Air-Damper-Illustration

Outside Air Ducting – One of the core concepts of clean air is ventilation. The old saying, “the solution to pollution is dilution, ” is certainly true when it comes to indoor air quality and heating and air conditioning. One way to provide fresh air is to install outside air ducting to supply a small amount of fresh air to your HVAC system. Properly introducing fresh air will allow for filtering, conditioning, treating, and distribution through the supply ductwork.

Energy Recovery Ventilator

Energy Recovery Ventilator Honeywell ERV from Empire HVAC

– If a simple outdoor air duct is not an option or if a higher level of ventilation is required, we often use an energy recovery ventilator (ERV) that can be integrated with your HVAC system or function as a standalone system. An ERV works by exhausting a specified amount of air and replacing it with fresh air from outside. The “energy” part comes in the form of a core that can salvage the heating or cooling you have already paid for. For example, if the temperature in your home is 70 degrees and the air outside is 40 degrees, the core would allow the outside air to be introduced into your home at about 55 degrees, allowing outdoor air to freshen the home without altering the indoor temperature. In cases where larger amounts of outside air are needed, this can be an extraordinary cost-saving feature for heating and cooling.

Air Treatment Products

Ultraviolet Germicidal Light –Field-Controls-UV-Germicidal-Light-UV-16-120-Aire from Empire HVAc Germicidal lights have been used in commercial and medical HVAC systems for decades and now that same technology can be used in residential systems as well. The air in your home is recirculated continuously throughout your ductwork and HVAC system, bringing viruses, bacteria, and mold spores along with it. Adding a simple Germicidal light can help control these unwanted pollutants. Germicidal lights are available both with and without ozone. We typically recommend avoiding ozone unless needed for a specific application or commercial task. The bulb in a germicidal light will need to be replaced annually to remain effective and cut down on airborne germs.

Photocatalytic Air PurifierField-Controls-UVPCO-Duo-24-volt-14-inch from Empire HVACUsing a Photocatalytic Air Purifier in conjunction with your HVAC system is an effective method to reduce airborne odors, chemicals, and VOC contaminants. Photocatalytic Oxidation (PCO) is a reaction that occurs when Titanium Dioxide (TiO2) is exposed to ultraviolet (UV) light rays. When VOCs, gaseous contaminants, and odors come into contact with the PRO-Cell™ surface, they are converted into odorless, harmless molecules of water vapor and carbon dioxide. The PCO unit uses the same type of ultraviolet light as the device above but adds extra purification with a honeycombed metal unit that is coated with titanium dioxide. We often use a PCO unit if outside air ventilation is not available or in applications where more aggressive treatment is needed to deliver proper air quality.

HumidificationAprilaire-Steam-Humidifier-800_07In southern cities like Atlanta, we only require about 2100 hours of heating each winter, so our demand for winter humidification is much lower than our northern neighbors. We still see homes that will have indoor humidity levels as low as 15% relative humidity, which can have negative side effects on you and your family like increased sensitivity to allergens, skin conditions, and static electricity. Your home can also be affected as the dry air pulls moisture out of indoor furnishings like cabinets and hardwood floors, making them more worn and rugged. Perhaps most importantly, low humidity can make it feel colder than it is, forcing you to crank up the thermostat. We have a full complement of powered central humidifiers to suit every application. The best unit for most residential and commercial applications is a steam-powered humidifier, which can provide the best level of on-demand humidity control. Other units are available that use an evaporative process and require a functioning heating system to produce humidity.

DehumidificationHoneywell-TrueDry-Dehumidifier-Family_Fam_DR65_DR90_DR120_LR from Empire HVAC During those humid Georgia summers, we’ve all heard that it’s not the heat that makes it unbearable, but the humidity. It is a fact that air conditioning does provide some dehumidification, but it just isn’t enough with our hot and often wet summers. When high humidity levels are limited to a specific area of the home (like a garage or basement), a mobile dehumidifier can be used for no-hassle operation. However, the most powerful and effective solution is usually a central dehumidifier that can be integrated with your HVAC system. A central dehumidifier can use the ductwork of your heating and cooling system to provide relief to all the areas of the home and can be configured to work even when the air conditioning isn’t running. Many sizes are available to properly fit your indoor space, both residential or commercial. Our advanced units can even be installed with features that allow the system to drain automatically or to shut down in the event of a malfunction so that you don’t have to worry about drainage buckets or plastic drain lines.

Duct Sealing – You may not think your ductwork should be a consideration for resolving indoor air quality, but unfinished or faulty ductwork can cause major changes in indoor air quality. Empire Heating and Air conditioning recommends testing the ductwork in your building as the first corrective action. This will identify faulty, leaky, or incomplete ducts that might allow allergens to enter the home. Leaky ductwork in attics and crawlspaces can draw in unwanted contaminants, cause pressurization issues in your home, and reduce the efficiency of your central HVAC system. We have the equipment and the training to properly test duct systems and determine if there are leakage levels that need to be identified, sealed, and protected for years of worry-free operation.

Low-Level Carbon Monoxide DetectionThe NSI-3000 Low-Level Carbon Monoxide Detector from Empire HVAC.

Carbon monoxide is responsible for thousands of deaths and injuries each year. It is an odorless, colorless gas that, when breathed in, reduces the flow of oxygen to the heart, brain, and other organs. Carbon monoxide poisoning can happen in virtually any home, especially those that use heating equipment of any sort, wood stoves, fireplaces, or have an attached garage. That’s why having a reliable carbon monoxide detector is so important. At Empire, we can assist you by providing you with the NSI-3000 low-level carbon monoxide monitor.

The main benefit of a low-level carbon monoxide detector is that it alerts you and your family when there are lower levels of the gas present in your home. Generally speaking, typical CO detectors alarm when carbon monoxide levels reach 70 parts per million. That means, CO gas can be present in the air your family is breathing, and can have a very serious effect on your health over time.

Repeated or continuous exposure to amounts as low as 20 parts per million is just as unhealthy as being exposed to a large amount of CO. This alarm can detect the low levels of CO present in your home where the less expensive models cannot, so you can take the appropriate safety measures before they become a serious concern.

The NSI-3000 features:

  • An advanced electrochemical sensor designed for accurate measurement of low levels of carbon
  • monoxide (CO) providing an early warning of toxic CO levels in your home
  • Detects carbon monoxide continuously
  • Resistant to false alarms caused by usual household contaminants
  • Sounds a loud 85 dB alarm to alert you in case of an emergency
  • Digital readout of CO level in parts per million (ppm)
  • A continuous circling line on the display when the reading is under five ppm
  • Remembers peak CO level until battery removal
  • Test/Reset button clears display to 0 ppm
  • Icons to identify various status conditions (reset button clears)
  • Simple to mount, portable, ideal for traveling
  • 5-year limited warranty (batteries excluded)
