Indoor Air Quality

Summer is in full swing now, and good air conditioning is essential for your family to stay comfortable during hot Florida afternoons. But since the pandemic is still going on, you might have some concerns about whether your HVAC system can contribute to the spreading of COVID-19. Here, we address common concerns you may have.

Can COVID-19 be transmitted through my HVAC system?

COVID-19, caused by the virus SARS-CoV-2, is mainly transmitted through droplets. Currently, there is no definitive scientific conclusion about whether these droplets can spread through your air distribution system. While it is theoretically possible for these droplets to stay in the air long enough to enter your HVAC system, some people say the chances of this happening are slim. Nonetheless, it is still advisable to take precautionary measures regarding your HVAC system.

Should I have my HVAC system cleaned?

It is a good idea to have your HVAC system cleaned. Besides helping to eliminate coronavirus particles that may be residing within the system, cleaning parts such as condenser coils and ductwork will keep your air conditioning running smoothly. It is important to note that cleaning your HVAC system would be a one-time sanitization, removing only particles that were already there. To keep your system clean in the future, you will have to repeat the cleaning or take other measures.

Wipe Down Fans and Vents

Dust and debris can build up on exhaust fans and vents throughout your home. When your air conditioning runs or when you use your exhaust fans, this dust and debris can then blow around your home. Wipe down vents in your home, and remove and clean the covers of exhaust fans with soap and water to remove debris and dust.

What other measures can I take to make sure COVID-19 doesn’t spread through my HVAC system?

There are several ways you can reconfigure your HVAC system to limit the spread of COVID-19.

  • Whole-home in-duct air purifier: A/C Designs offers the REME HALO® Whole Home In-Duct Air Purifier to be installed to your unit. The REME HALO® is the next generation of indoor air quality (IAQ) technology and capable of purifying every cubic inch of air that your central air conditioning system reaches. Designed to eliminate sick building syndrome risks by reducing odors and air pollutants, the REME HALO® whole home in-duct air purifier is the best solution for the whole house and building air purification. This device reduces common allergy triggers from particulates such as pollen, mold spores, dander, and dust. Thoroughly tested on airborne and surface bacteria & viruses*, such as MRSA, e-coli, and Norwalk, to name a few.
  • High-efficiency HVAC filter: A high-efficiency filter is able to capture small particles, including viruses, thereby removing them from your air. However, there are some tradeoffs to be aware of when using a high-efficiency filter. Since high-efficiency filters trap more debris, they need to be cleaned and changed more often. Also, high-efficiency filters do not allow for as much air penetration. When less air is flowing through your system, the system can struggle to keep your home cool and reach the set temperature. It is worth noting that the coronavirus might be too small for the system to trap every particle.
  • UV Germicidal Lights: Ultraviolet light can kill microorganisms such as viruses that live on your HVAC ducts. While it has been shown to work against some coronaviruses, there is nothing definitive yet about the effect of UV and SARS-CoV-2. However, it could still be worth installing to be on the safe side.
