When you think about air pollution, you probably picture traffic, industrial areas, pollen or, increasingly, smoke from distant wildfires. But the quality of the air inside your Lawrenceville home matters just as much.
Recent periods of haze and smoke reaching the Southeast from Canadian wildfires have been a good reminder that outdoor air quality problems don’t necessarily stop at your front door. Fine particles from wildfire smoke can find their way indoors, while everyday indoor contaminants such as dust, pet dander, pollen, cooking particles and other airborne pollutants can accumulate inside your home.
Fortunately, your heating and cooling system can play an important role in creating cleaner, healthier indoor air.
Why Indoor Air Quality Matters in Lawrenceville, GA
Lawrenceville homeowners already deal with plenty of outdoor air quality challenges throughout the year. Georgia’s long pollen season is an obvious one, but humidity, dust, mold spores and other airborne particles can also affect the comfort of your home.
Wildfire smoke adds another potential concern. Even when the fires themselves are hundreds or thousands of miles away, changing weather patterns can transport smoke over large portions of the country. During smoky conditions, some of those fine particles can enter homes through doors, windows, gaps and ventilation systems. And simply closing your windows isn’t always enough.
That’s where a combination of proper HVAC filtration, air purification and humidity control can make a significant difference.
Start With the Right HVAC Air Filter
Your HVAC filter is one of the first lines of defense against airborne particles circulating through your heating and cooling system. However, not every filter provides the same level of filtration.
Filters are commonly rated using the MERV (Minimum Efficiency Reporting Value) system. In general, a higher MERV rating means the filter is capable of capturing smaller airborne particles.
During periods of wildfire smoke, the U.S. Environmental Protection Agency recommends using a MERV 13 filter, or the highest-efficiency filter your HVAC system can safely accommodate.
Check Your Filter More Frequently During Smoky Conditions
Wildfire smoke and unusually poor outdoor air quality can also cause filters to become dirty more quickly. If Lawrenceville is experiencing smoky or hazy conditions, it’s a good idea to inspect your HVAC filter more frequently than you normally would. A heavily loaded filter may restrict airflow and won’t perform as effectively as a clean one.
Consider a Whole-Home Air Purification System
For homeowners who want to go beyond standard HVAC filtration, a whole-home air purification system can provide another layer of indoor air quality protection. Unlike a portable air purifier that primarily treats one room, whole-home systems work with your HVAC equipment to address air circulating throughout the house.
Depending on the system, whole-home air quality equipment may help reduce airborne dust and fine particles, pollen, pet dander, mold spores, smoke particles and other common household airborne contaminants.
The right solution depends on your home, existing HVAC system and specific indoor air quality concerns.
Use Your HVAC System Wisely When It’s Smoky Outside
If wildfire smoke is affecting air quality in Lawrenceville, your HVAC settings can make a difference. Keep doors and windows closed while outdoor air quality is poor. If your HVAC or ventilation system has a fresh-air intake, consider closing it or switching the system to recirculate mode so you’re not intentionally pulling smoky outdoor air into the house.
With an appropriate high-efficiency filter installed, running the HVAC fan more frequently can also help filter particles from the indoor air. Once outdoor air quality improves, normal ventilation can resume.
Don’t Forget About Georgia Humidity
Particles aren’t the only indoor air quality concern in Lawrenceville. Georgia’s high humidity can make homes uncomfortable and may contribute to conditions that encourage mold and mildew growth.
Ideally, your air conditioning system removes both heat and moisture as it operates. But oversized equipment, ductwork issues, short cycling and other HVAC problems can interfere with effective humidity control.
For homes that continue to feel damp or muggy even when the air conditioner is running, a whole-home dehumidifier may be worth considering.
Unlike small portable units, whole-home dehumidification systems can work alongside your HVAC equipment to manage moisture throughout the house.
Your Ductwork Matters, Too
The air moving through your HVAC system travels through your home’s ductwork, making the condition of those ducts another part of the indoor air quality equation.
Leaks in ductwork can potentially pull air from attics, crawlspaces and other undesirable areas into the HVAC system. That can introduce additional dust and contaminants while also wasting conditioned air.
If you notice excessive dust, uneven temperatures or unusually high heating and cooling bills, having your HVAC system and ductwork inspected can help identify potential problems.
A Healthier Home Starts With Cleaner Air
You can’t control pollen season in Georgia, and you certainly can’t control when smoke from distant wildfires drifts across the Southeast. But you can take steps to improve the air circulating inside your Lawrenceville home. Better HVAC filtration, whole-home air purification, humidity control and a properly maintained heating and cooling system can all contribute to cleaner, more comfortable indoor air.
