HVAC Tips For Your Home

If your home has a forced-air system (HVAC), it’s important to understand how it works—especially during the coronavirus (COVID-19) outbreak. Knowing the basics can help you take steps to get cleaner, more efficiently circulated air in your home while keeping allergens and other unwanted particles at bay.

This guidance comes from the U.S. Centers for Disease Control and Prevention (CDC), the U.S. Environmental Protection Agency (EPA), and the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE).1

What is a forced-air system?

HVAC stands for heating, ventilation, and air conditioning. The HVAC system in your home is designed to help you control the temperature, humidity, circulation rate, and indoor air quality. Your HVAC system will either provide air conditioning only or a combination of air conditioning and heating. Both types have a fan that pulls heated or cooled air through a filter and distributes temperature and humidity-controlled air through the vents. Depending on the type of HVAC air filter you select, it may be able to capture millions of invisible particles like dust, pet dander, pollen, exhaust, tobacco smoke, viruses, and bacteria from the air passing through the filter.

What can I do to keep my HVAC system running properly?

HVAC systems are designed to heat and cool your home to comfortable temperatures, and they operate best in these temperatures, too. The air in the room with your HVAC should stay between 68 and 78 degrees with 40 to 60% humidity.¹ You should replace the air filter often and use high-efficiency Filtrete™ HVAC filters with a MERV rating of 12 or higher (MPR 1500 or higher for Filtrete™ HVAC Air Filters).¹ The cleaner your filter, the better it catches small unwanted airborne particles, so make sure you’re replacing it on the schedule recommended on the filter’s packaging. For more accurate guidance on when to change your filter, our Filtrete™ Smart Filter and compatible Filtrete™ Smart App allow you to track filter life in real-time and receive filter change notifications based on usage. The app also works with other Filtrete™ air filters—simply scan your filter’s barcode to start a personalized timer.

Also, HVAC systems do the best job cleaning your air when they’re used consistently, so keep the system running on a low fan setting at all times.

What should I know about air vents?

Before you turn on the heat or air conditioning, give your vents a good dusting. If your vents aren’t clean, forced-air systems can kick up dust and other unwanted air intruders that might have settled in those nooks and crannies. Remove the duct covers and wash them with warm, soapy water, and dust just inside the vents. If you want to give your HVAC system a deep clean, you can hire a professional to carefully clean all of your air ducts.

Can I use my HVAC system to get the coronavirus particles out of the air?

Although air filtration systems like HVACs using certain high-performing filters and standing air purifiers can help filter out virus particles, they’re not enough on their own to protect people in your home from contracting COVID-19.¹ Continue to follow CDC recommended best practices, such as wearing a mask in shared spaces around others, washing your hands and cleaning surfaces often, maintaining social distancing, and isolating anyone within your home that is sick or may have been exposed to the virus.²

How else can I circulate air in my home?

Opening windows, turning on ceiling fans and operating exhaust fans in your kitchen and bathrooms can also help circulate your indoor air. Portable air cleaners, such as Filtrete™ Air Purifiers, can also help clean the air in one room at a time.³
