Indoor Air Quality Solutions - Air Filtration System Sales & Installation, Northridge, CA

In addition to having clean, well-sealed ductwork, a good air filtration system is the other main contributor to having cleaner, healthier air in your home or business. This is particularly important in Northridge and other parts of the Santa Clarita and San Fernando Valley, where Santa Ana winds frequently stir up dirt, pollen, ash, and other contaminants. These contaminants easily get indoors through windows, doors, and cracks in the house and are then circulated throughout the house or building via the central heating and air conditioning system. To remove such contaminants, you'll want to change your HVAC system's filter on a regular basis and perhaps consider upgrading your air filtration system. For example, Carrier's Infinity Series Air Purifier doesn't just filter the air; it traps and kills viruses, bacteria, mold, and other pathogens as well as captures and removes the most common allergens, such as pollen. If you'd like to improve the air quality at your home or business, call the Healthy Air Experts at Zodiac Heating & Air Conditioning, Inc. today.
