Allergens in the home, such as pollen, dust mites, and pet dander, can significantly impact the comfort and health of allergy sufferers. Upgrading your HVAC system can play a crucial role in reducing these allergens and improving indoor air quality. Here’s how strategic upgrades can help:

Enhanced Filtration Systems

One of the most effective ways to reduce allergens through HVAC upgrades is by improving the filtration system.

  • HEPA Filters: Installing High Efficiency Particulate Air (HEPA) filters can dramatically reduce the presence of allergens in your home. HEPA filters can capture particles as small as 0.3 microns, effectively removing nearly 99.97% of airborne pollutants.
  • Electrostatic Filters: These use an electric charge to attract and trap airborne particles, including allergens, which can be especially useful for homes in urban areas like Philadelphia where air quality may be compromised.

Sealed and Improved Ductwork

Leaky ductwork can allow dust and other allergens to circulate throughout your home. Sealing and insulating ducts can prevent allergen entry and improve overall system efficiency.

  • Duct Sealing: Professional sealing of ductwork reduces the risk of allergens and pollutants from entering and being distributed by your HVAC system.
  • Regular Duct Cleaning: Periodic cleaning of ducts removes any accumulated dust, mold, and other allergens, ensuring cleaner air distribution.

Humidity Control

Maintaining optimal humidity levels can also help reduce allergens. Too much humidity encourages the growth of mold and dust mites, while too little can exacerbate respiratory symptoms.

  • Dehumidifiers and Humidifiers: Integrated solutions that control humidity can help maintain it within the ideal range of 30-50%, mitigating the proliferation of mold and dust mites.

Advanced HVAC Systems

Modern HVAC systems equipped with smart technology can automatically adjust settings based on real-time air quality and humidity levels, enhancing comfort and reducing allergen exposure.

  • Smart Thermostats: These devices can be programmed to adjust indoor temperatures and humidity levels, optimizing conditions to minimize allergens.

UV Light Systems

UV light systems installed within the HVAC system can help destroy microorganisms such as mold, bacteria, and viruses before they enter your indoor air.

  • In-Duct UV Treatment: This can significantly reduce airborne pathogens that can trigger allergies.


Upgrading your HVAC system with advanced filtration, proper ductwork, and humidity control can significantly enhance indoor air quality and reduce allergens in your home. For families in Philadelphia, where changes in seasons can introduce different allergens, these upgrades are particularly beneficial. Consulting with HVAC experts like those at McCorry Comfort can ensure that your system is optimally configured to handle allergens effectively, making your home a healthier place to live.
