April showers bring May flowers, but springtime also means a wave of pollen, dust, and other allergens arrive which can easily make their way into your home and impact your indoor air quality.
Indoor air quality (IAQ) refers to the cleanliness and health of the air inside your home. Improving it is essential for creating a more comfortable and healthy living environment for you and your family.
Sneezing, runny noses, worsening respiratory issues, and lingering coughs are just a few of the common symptoms you can expect when flowers bloom and springtime pollen appears. For households with allergies, asthma, pets, or young children, these issues can become even more noticeable.
But you don’t have to just wait— improving your indoor air quality quickly this spring is easier than you think with these 5 expert HVAC tips from Charlotte Mechanical’s top technicians:
1 - Replace Your Air Filter
Air filters are your home’s first line of defense against dust, pollen, pet dander, and other airborne contaminants. Over time, filters become clogged and less effective. Once they can no longer capture anything new, air filters will allow pollutants to circulate in your home, worsening the air your family breathes.
Replacing your air filter regularly helps your HVAC system to properly capture more allergens, improves airflow, and keeps your system running efficiently.
How often should you replace your filter? It depends on the type. Small filters may need to be replaced monthly, while larger, high-capacity filters can last for several months. In general, we recommend replacing most filters seasonally.
2 - Run HVAC Fan + Increased Circulation
Your HVAC system does more than just heat and cool— it also has the important job of circulating air throughout your home. Running your HVAC fan in the “On” setting helps move air through the filtration system, reducing stagnant air and limiting the buildup of dust and other contaminants.
This reduces stagnant air, limits the buildup of dust and allergens, and can help prevent musty odors. It’s a simple way to improve overall air circulation and reduce allergies.
3 - Keep Your Vents and Air Grilles Clean
Spring cleaning doesn’t stop at closet clean-outs and decluttering! Air vents and return grilles are essential for airflow in each room of your house, but they’re often overlooked during routine cleaning. Dust and debris can build up, which allows these contaminants to be pulled back into your system and recirculate to every room in your home.
Making sure there is no build up or other obstructions on your vents will also allow your HVAC system to run more efficiently and puts less strain on your system!
4 - Add an Air Purifier, Air Scrubber, or UV Lights
Want to get serious about reducing allergies or asthma symptoms at home? Consider adding indoor air quality equipment to your HVAC system.
IAQ equipment like air purifiers and air scrubbers provide added layers of filtration to capture small airborne particles, while UV lights help reduce mold, bacteria, and other microorganisms inside your system.
