What is Air Quality?

Air quality refers to the level of pollutants in the air we breathe. These pollutants include particulate matter (PM), ozone, and nitrogen dioxide. High levels of these pollutants can harm human health, particularly for people with respiratory issues such as asthma and chronic obstructive pulmonary disease (COPD).

Steps to Improve Indoor Air Quality

You can take several steps to improve indoor air quality when outdoor air quality is poor. These include:

  • Keep your home clean: Vacuum and dust frequently to remove pollutants from surfaces.
  • Avoid smoking indoors: Cigarette smoke can be a significant source of indoor air pollution.
  • Use natural cleaners: Avoid harsh chemical cleaners that can release pollutants into the air.
  • Monitor outdoor air quality: Keep an eye on air quality reports and avoid outdoor activities during high pollution.

Ensure your AC is functioning properly and not adding pollutants to the air. Regular maintenance and repairs, such as air conditioning repair in Burlington, can help keep your system running efficiently.

Factors To Consider While Using Your AC When Air Quality Is Poor

When it comes to using your AC when air quality is poor, there are a few factors to consider, such as:

Type of AC System:

The type of AC system you have can affect whether you should use it when air quality is poor. For example, central air conditioning systems recirculate indoor air, which means that the air inside your home is filtered before it is cooled and returned to the living space. In this case, ensuring your filters are clean and in good condition is essential. On the other hand, window AC units and ductless mini-split systems typically draw in outdoor air, meaning using them when air quality is poor could make things worse. In this case, keeping your windows closed and using fans to circulate indoor air is best.


The filters you use in your AC system can significantly affect indoor air quality. HEPA filters are the gold standard for clearing airborne particles but can be expensive. If you can’t afford HEPA filters, look for filters with a MERV rating of 11 or higher. These filters can remove a range of pollutants from the air, including PM and allergens. If you are facing issues with the filter, you can rely on our air conditioning repair services in Burlington and surrounding areas.

Outdoor Air Quality:

The quality of outdoor air is a significant factor in whether you should use your AC when air quality is poor. If outdoor air quality is especially bad, using your AC may not be enough to protect your health. In this case, it’s best to avoid spending time outside and to take steps to improve indoor air quality.

Considering the factors above, you may use your AC on days when the air quality is poor. However, suppose you’re worried about indoor air quality.
