The COVID-19 pandemic has many people considering ways to reduce the risk of transmission. Beyond social distancing, wearing masks, and washing hands, many people want to know if viruses can be circulated or prevented within a residential HVAC system. The case study that brought this to light related to a restaurant outside the United States where it is believed that transmission occurred due to the air conditioning system. Here are five facts to know about viruses and your HVAC system.

1. Proper Ventilation Is Key

Ventilation throughout your house is important, not only for preventing you from getting sick but also for keeping your family comfortable. Any type of airborne substance, such as pollen, bacteria, mold, or dust, will remain inside a structure if the ventilation is not adequate to circulate the air. HVAC systems bring little, if any, air from the outdoors, so what is inside your home stays in your house. If you want to improve ventilation, you can open a window to bring in fresh air. If someone in your household is ill, we recommend that you limit airflow from the room in which the person is recovering. Weather Masters Corp. in Frederick can perform an in-home evaluation to determine if your HVAC system is working properly and circulating air.

2. Filtration Removes Airborne Particles

Commercial and residential HVAC systems have a series of filters that are designed to trap most airborne particles, but no filter will capture 100% of what is in the air. The filters should be changed several times throughout the year depending on use. You should also change the filters should anyone in your home be ill or have certain respiratory issues, such as asthma, allergies, COPD, or lung disease. If you are unsure of which filter to use for your needs, Weather Masters Corp. helps Frederick homeowners like you to determine the best filters for their systems. We are a full-service heating and cooling company that offers installations, repairs, and maintenance services.

3. Public Health Recommendations Protect You

Even with the best filters and most efficient heating and cooling system, you still should follow public health recommendations that are outlined for residents of Frederick and the surrounding areas. Limit the number of people who come into your residence, and be sure to isolate anyone who is ill or has been around someone who is ill. Wash your hands regularly with soap and water, and avoid touching your face, too.

4. Highest Risk Is in Public Settings

Whether a virus is passed through the HVAC system or naturally circulated in a closed room, public indoor settings represent the highest risk or viruses and illnesses. Scientists continue to study data from situations where COVID-19 was passed to several patrons in a restaurant, so your best bet is to avoid these types of environments. Risk is significantly reduced when you are at home unless someone is ill.

5. All Surfaces Should Be Cleaned and Disinfected

Any particles that are in the air of your home are certain to land on surfaces, fabrics, and carpets. Particles that land on textiles become airborne again when you sit or walk. Make cleaning and disinfecting part of your weekly routine, and be sure to vacuum floors and furniture. While viruses may not live long enough on the various surfaces inside your house, these practices will give you extra peace of mind. If you notice that you have a good accumulation of dust around your residence, your HVAC system may need some routine maintenance. Weather Masters Corp. offers maintenance services for heating and cooling systems to identify areas where airborne particles may be entering the system and coming inside your household.
