How to Improve Indoor Air Quality with Your Existing HVAC System Jun 27, 2025

Maintaining optimal indoor air quality is crucial for a healthy and comfortable home environment. Many homeowners, however, are unaware that their existing HVAC system plays a pivotal role in this process. Brannan’s Heat and Air, a leader in HVAC services, is committed to helping you understand how you can leverage your system to enhance the air quality within your home.

First, it is essential to appreciate the role of your HVAC system in circulating and filtering the air you breathe daily. As your primary line of defense against airborne contaminants, ensuring your system is functioning at its best can significantly impact indoor air quality. Here are some strategies to improve air quality using your existing HVAC setup without having to make significant upgrades.

Regular maintenance is the cornerstone of an efficient HVAC system. Scheduling routine check-ups with Brannan’s Heat and Air ensures that your system is not only running efficiently but also capable of adequately filtering out pollutants. During these maintenance visits, technicians will check and clean various components, including filters, coils, and ductwork, which can accumulate dust and debris over time. Keeping these clean is essential for preventing recirculation of contaminants.

Speaking of filters, replacing them regularly is arguably the simplest and most effective way to improve air quality. Filters capture dust, pollen, mold spores, and other irritants. Depending on your specific needs, you might opt for high-efficiency particulate air (HEPA) filters, which are designed to trap the smallest particles. It is advisable to replace standard filters at least every three months, more frequently if you have pets or allergy sufferers in the household.

Another effective strategy involves checking and adjusting the humidity levels within your home. Excessive humidity can lead to mold growth, while low humidity can result in dry skin and irritated respiratory passages. Your HVAC system can help maintain a balanced humidity level through the use of a humidifier or dehumidifier, ensuring that the air quality remains optimal year-round. A relative humidity level between 30-50% is generally considered ideal.

Regularly inspect your ductwork for leaks or blockages. Leaks in the ducts can introduce pollutants and allergens into your system, severely affecting the quality of the air circulated throughout your home. By having ductwork inspected and sealed by professionals at Brannan’s Heat and Air, you can ensure that your system is airtight and efficiently filtering the air.

In addition to these measures, consider investing in an air purifier to supplement your HVAC system’s efforts. While these are standalone devices, they work in tandem with your HVAC system to further enhance air quality, capturing pollutants that the system’s filters may miss.

Finally, adopting simple practices such as regular dusting and vacuuming can significantly reduce indoor air pollutants. Using vacuums equipped with HEPA filters can further help in trapping fine particles.

Improving indoor air quality is an ongoing process that involves both your HVAC system and vigilant household practices. By implementing these tips, you can enjoy a healthier home environment with cleaner, fresher air.
