HVAC systems provide a steady flow of conditioned air to keep indoor spaces comfortable all year long. They also reduce allergens like pollen, dust, and pet dander, promoting easy breathing and preventing allergy flare-ups. Here's how your heating and air conditioning unit can minimize these pollutants and freshen the air. 

4 Ways HVAC Systems Reduce Allergens 

1. Humidity Control 

Your air conditioner removes excess moisture from indoor air during the summer, keeping indoor humidity levels between the recommended range of 30% to 50%. This prevents your home from becoming too moist, ensuring comfort and creating an environment that doesn't promote mold growth. As a result, you'll have a reduced risk of inhaling fungal spores, which can cause allergenic rhinitis, asthma attacks, and potentially serious lung infections. Though the AC is designed to lower humidity inside, installing a dehumidifier in your existing HVAC system can maximize your home's humidity control. 

2. Hypoallergenic Filter

HVAC systems use a filter that traps debris as air enters the unit. This helps clean the air before your system blows it through vents in rooms. Though a standard filter is somewhat adequate, upgrading to a whole-home hypoallergenic filter can offer a high level of protection against smaller particles, such as mold spores and dust mites. 

These products feature a pleated, layered design with greater surface area, allowing them to capture more debris. Additionally, they're electrostatically charged, which can permit them to attract greater amounts of particulate matter and keep breathable air clean. 

3. UV Light System 

Air conditioners use an evaporator coil filled with refrigerant to absorb heat from intake air. This component may release condensation as a result of temperature fluctuations, and the moisture creates a favorable environment for fungal growth. Any mold or mildew spores that grow on the coil may circulate through the system and enter your home. 

A UV light system uses a lamp installed near the coil. It uses light and heat energy to keep the coil dry and prevent harmful microbes from entering conditioned air. Since it's positioned near the air intake, it can destroy harmful pollutants year-round, even when using the furnace.

4. Air Purifier

Fans move air through a series of high-efficiency particulate air (HEPA) filters, which can trap up to 75% of allergens with a size of 0.3 microns, including microscopic fungi, bacteria, and viruses. You may use portable purifiers in rooms of the home as extra filtration and protection against allergenic particulate matter. Alternatively, a whole-whole purifier is installed in the HVAC system to handle all the air that's circulated through the home.
