Atlanta's AC: Is New Drywall Hiding Deadly VOCs?
By Franklin Everett ShawThe air in your Atlanta home feels heavy, doesn’t it? That “new house smell” might be more sinister than you think, especially if you’ve recently had drywall installed. It could be volatile organic compounds, or VOCs, off-gassing into your living space, and your AC system might be making the problem worse. Let’s dive into how to tackle this invisible threat head-on, specifically tailored for the unique challenges of Atlanta’s climate and housing market.
VOCs are emitted from many building materials, including drywall. These chemicals can cause a range of health problems, from headaches and nausea to more serious respiratory issues. New drywall is a significant source, and the problem is exacerbated in humid environments like Atlanta, where off-gassing can be prolonged.
The first step is understanding the drywall you’re using. Standard drywall often contains formaldehyde and other VOCs. Opting for low-VOC drywall is crucial. Look for products certified by organizations like GreenGuard or UL GREENGUARD Gold. These certifications indicate that the drywall has been tested and meets stringent standards for low chemical emissions.
CertainTeed AirRenew drywall is a good example. It actively removes VOCs from the air, converting them into inert compounds. While it’s not a complete solution, it’s a proactive step. Another option is USG Sheetrock UltraLight, which boasts lower VOC emissions compared to standard drywall.
Now, let’s talk about your AC system. In Atlanta’s sweltering summers, AC is a necessity, but it can also trap VOCs indoors. The key is ventilation. Your AC system should be set to circulate fresh air regularly. Most modern systems have a fresh air intake setting. Use it!
Consider installing a whole-house ventilation system, like an energy recovery ventilator (ERV) or a heat recovery ventilator (HRV). These systems bring fresh air into your home while exhausting stale, VOC-laden air. They also help regulate humidity, which is a major factor in VOC off-gassing.
Here’s a practical tip: Run your AC fan on “auto” instead of “on.” This ensures the fan only runs when the compressor is cooling, reducing the amount of air circulated and potentially trapping VOCs. When you’re not home, open windows (when the weather permits) to air out the house.
DIY solutions can also help. Activated carbon filters are effective at absorbing VOCs. Place them strategically around your home, especially near the new drywall. Baking soda is another natural odor absorber. Place open boxes of baking soda in rooms with new drywall.
Houseplants can also play a role. Certain plants, like spider plants and snake plants, are known for their air-purifying qualities. While they won’t eliminate VOCs entirely, they can help improve indoor air quality.
However, don’t rely solely on DIY methods. Professional VOC testing is essential to determine the extent of the problem. Several companies in the Atlanta area offer VOC testing services. Prism Analytical Technologies and EMSL Analytical are two reputable options.
These companies will collect air samples from your home and analyze them in a lab to identify the specific VOCs present and their concentrations. This information is crucial for developing an effective remediation plan.
If testing reveals high VOC levels, professional remediation may be necessary. This could involve sealing the drywall with a low-VOC sealant, removing and replacing the drywall, or installing a whole-house air purification system. Companies like AdvantaClean of Buckhead and PuroClean of Decatur specialize in indoor air quality remediation.
One common mistake homeowners make is assuming that the “new house smell” will dissipate on its own. While some VOCs will eventually dissipate, others can linger for months or even years. Ignoring the problem can lead to long-term health issues.
Another pitfall is using standard paints and finishes on the new drywall. These products can also emit VOCs, negating the benefits of using low-VOC drywall. Always choose low-VOC paints and finishes for all surfaces in your home.
Consider the impact of humidity. Atlanta’s high humidity levels can exacerbate VOC off-gassing. Dehumidifiers can help control humidity levels, reducing the rate at which VOCs are released from the drywall. Aim for a humidity level between 30% and 50%.
Don’t forget about the HVAC system maintenance. Regularly change your air filters to ensure optimal airflow and filtration. A clogged air filter can reduce the efficiency of your AC system and trap VOCs indoors.
Here’s a step-by-step guide to mitigating VOC off-gassing from new drywall in your Atlanta home:
- Choose low-VOC drywall: Opt for products certified by GreenGuard or UL GREENGUARD Gold.
- Ventilate your home: Use your AC system’s fresh air intake setting or install a whole-house ventilation system.
- Use DIY solutions: Place activated carbon filters and baking soda around your home.
- Consider houseplants: Add air-purifying plants like spider plants and snake plants.
- Get professional VOC testing: Contact a reputable company like Prism Analytical Technologies or EMSL Analytical.
- If necessary, hire a professional remediation company: Companies like AdvantaClean of Buckhead and PuroClean of Decatur can help.
- Use low-VOC paints and finishes: Choose low-VOC options for all surfaces in your home.
- Control humidity levels: Use a dehumidifier to maintain a humidity level between 30% and 50%.
- Maintain your HVAC system: Regularly change your air filters.
- Monitor air quality: Continue to monitor your indoor air quality to ensure VOC levels remain low.
Remember, addressing VOC off-gassing is an ongoing process. It requires a combination of careful product selection, proper ventilation, and regular monitoring. By taking these steps, you can create a healthier and more comfortable living environment for yourself and your family in your Atlanta home. Don’t let the “new house smell” fool you; take proactive steps to protect your indoor air quality.
