You might be surprised to learn that the air inside your home can actually be more polluted than the air outside! That’s because our homes are full of potential sources of air pollutants — dust mites, pet dander, cleaning chemicals, even cooking fumes. These microscopic irritants can aggravate allergies and asthma and generally leave you feeling less than your best. Fortunately, there’s a simple solution to combating these pollutants: enhancing the performance of your HVAC system.
That’s right: your heating and cooling system significantly affects the quality of the air in your home. If not properly cared for, this system can cause your indoor air quality (IAQ) to decline. But this also means that you can do a few simple things to improve the air you breathe. Let’s take a closer look at how exactly your HVAC system affects indoor air quality.
How Your HVAC System Affects Indoor Air Quality
Your HVAC system and its various components, including the air handler, air filters, and air ducts, are essential for regulating the temperature and airflow in your home. However, it also has a significant impact on your indoor air quality. Here are some key ways your HVAC system affects indoor air quality:
1. Air Filtration
The air filters in your HVAC system are designed to capture dust, pollen, pet dander, and other airborne particles. If these filters are not changed regularly, they can become clogged and less effective, allowing pollutants to circulate throughout your home. Dirty filters can also strain your HVAC system, reducing its efficiency and lifespan.
2. Humidity Control
Humidity levels in your home can significantly affect indoor air quality. That’s why your HVAC system is designed to help control humidity by removing excess moisture from the air. Of course, if your system is unable to work properly, it can result in poor humidity levels. And this is bad news on either side of the spectrum. High humidity levels can promote the growth of mold, dust mites, and other allergens, which can negatively affect indoor air quality. Conversely, low humidity levels can cause dry skin, irritated respiratory passages, and an increased risk of respiratory infections.
3. Air Circulation and Ventilation
Proper air circulation and ventilation are crucial for maintaining good indoor air quality. Your HVAC system helps circulate air throughout your home, ensuring that fresh air replaces stale air. Without adequate ventilation, pollutants and volatile organic compounds (VOCs) can build up, leading to poor indoor air quality.
4. Ductwork Condition
The condition of your air ducts also plays a vital role in the quality of air circulating throughout your home. Over time, dust, debris, and even mold can accumulate in your ductwork, reducing airflow and spreading contaminants throughout your home. Fortunately, regular duct cleaning can help maintain good indoor air quality.
Ways to Use Your HVAC System to Improve IAQ
Understanding how your HVAC system affects indoor air quality is the first step. The next step is to take actionable measures to improve it. Here are some practical ways to use your HVAC system to enhance indoor air quality in your home:
1. Regular Maintenance of HVAC System
Regularly maintaining your HVAC system is the key to boosting indoor air quality. All you need to do is change the air filters every 1-3 months, have your system inspected and serviced by professionals at least once a year, and ensure all components are clean and functioning correctly.
2. Upgrade Your Air Filters
Consider upgrading to high-efficiency air filters, such as HEPA filters, which can capture smaller particles and improve indoor air quality. Also, regardless of which filter you choose, check its MERV rating (Minimum Efficiency Reporting Value); the higher the MERV rating, the better the filter is at trapping specific types of particles.
3. Use Air Purifiers
Installing air purifiers can help remove contaminants from the air, including VOCs, dust, pollen, and pet dander. These can be standalone units or integrated into your HVAC system for whole-house purification.
4. Control Humidity Levels
Invest in a humidifier or dehumidifier to maintain optimal humidity levels in your home. Aim for humidity levels between 30-50% to prevent the growth of mold and dust mites and to ensure comfort and health.
5. Ensure Proper Ventilation
Ensure your home has adequate ventilation to allow fresh air to enter and stale air to exit. This can be achieved through natural ventilation (opening windows and doors) or mechanical ventilation systems integrated into your HVAC system.
6. Clean and Seal Ductwork
Have your air ducts professionally cleaned every 3-5 years to remove accumulated dust, debris, and mold. Also, check for and seal any leaks in your ductwork to ensure efficient airflow and prevent contaminants from entering the system.
