When it comes to HVAC maintenance, many homeowners understand the importance of things like regular filter replacements, annual tuneups, and other services. However, indoor air quality is often overlooked, as many people assume that the air inside their homes is cleaner than what’s outside. In the article below, look at a few key factors affecting indoor air quality at home and what you can do about them.

What Are Some Aspects Affecting Indoor Air Quality?

1. Ventilation

In homes with poor ventilation, airborne dirt, allergens, and microbes can become trapped inside and continually recirculated through ducts and vents. Whenever possible, it’s a good idea to open your windows and turn on a fan to move stale air, along with dust and other contaminants, outside and fresh air in. For those living in the southeast, having an ERV (energy recovery ventilator) might be a better option to bring fresh air in consistently, especially when it's too hot, too cold or there is too much pollen in the air.

2. Humidity Levels

Humidity refers to the amount of water vapor present in the air. As a rule, it’s best not to have an indoor humidity level that is either too high or too low. Too little humidity can leave rooms feeling dry and raise the risk of cracking and other forms of physical damage to drywall, wood, and other materials. Excessive humidity can contribute to the conditions needed for mold and mildew spores to establish new colonies.

Indoor humidity levels should ideally fall between 40% and 50%. You can lower humidity levels with a dehumidifier or by running your heating. If your home is too dry, use a humidifier to raise humidity levels as necessary.

3. HVAC Maintenance

Poor indoor air quality may also result from issues affecting heating and cooling systems. For example, ducts that haven’t been cleaned for some time may contain large amounts of dust and dirt which can raise the risk of illnesses and irritation. 

Alternatively, excessive condensation caused by poor ventilation or blockages can contribute to mold and mildew growth. You can avoid these issues by scheduling regular HVAC maintenance and cleaning services.
