As people spend more time indoors, it’s important to pay attention to the quality of the air we breathe. According to the Environmental Protection Agency, indoor air can be 2-5 times more polluted than outdoor air. With the help of your HVAC system, you can improve your indoor air quality and create a healthier living environment for you and your family. Here are some tips from an air conditioning company for improving indoor air quality with your HVAC system.

Change your air filters regularly

The air filter in your HVAC system is responsible for trapping dust, dirt, and other particles that can circulate throughout your home. Over time, these filters become clogged and less effective at capturing pollutants. Make it a habit to check and replace your air filters every three months, or more often if you have pets or allergies. A clean air filter will not only improve the air quality in your home but also help your HVAC system run more efficiently.

Use high-efficiency air filters

Not all air filters are created equal. Look for high-efficiency filters with a MERV rating of 11 or higher. These filters are designed to trap smaller particles like pollen, mold spores, and pet dander that can cause respiratory problems. Keep in mind that high-efficiency filters may need to be changed more frequently than standard filters, so check them every two months.

Install an air purifier

If you have severe allergies or live in an area with high pollution, consider installing an air purifier in your home. Air purifiers can capture pollutants that may be missed by your HVAC system’s air filter. There are several types of air purifiers available, including mechanical filters, electrostatic filters, and UV light purifiers. Each type has its own advantages and disadvantages, so do your research before purchasing one.

Seal your home

Leaks and gaps in your home’s structure can allow pollutants to enter your home. Sealing your home’s windows, doors, and ducts can help prevent outdoor air pollutants from entering your home. It can also prevent heated or cooled air from escaping, which can improve the energy efficiency of your HVAC system.

Maintain your HVAC system

Regular maintenance of your HVAC system is important for improving indoor air quality. Dirt and dust can accumulate in your system, which can lead to poor air quality and decreased efficiency. Hire a professional HVAC technician to perform annual maintenance on your system, including cleaning the ducts and coils, checking refrigerant levels, and inspecting the blower motor.

Use natural cleaning products

Many common household cleaning products contain volatile organic compounds (VOCs) that can contribute to poor indoor air quality. Use natural cleaning products, such as vinegar and baking soda, instead of harsh chemicals. You can also look for cleaning products that are labeled as “Low VOC” or “No VOC.”

Control humidity levels

Humidity levels that are too high or too low can contribute to poor indoor air quality. Use a humidifier in the winter when the air is dry, and a dehumidifier in the summer when the air is humid. Keep humidity levels between 30-50% to prevent mold growth and improve respiratory health.


Ventilate your home

Proper ventilation is essential for improving indoor air quality. Open your windows and doors to let fresh air into your home. You can also install a ventilation system that circulates outdoor air into your home while expelling indoor air. This can help remove pollutants that may be trapped inside.


In conclusion, improving indoor air quality is essential for maintaining a healthy living environment. By following these tips from the best air conditioning company, you can ensure that your HVAC system is working efficiently and effectively to remove pollutants.
