Indoor air quality is a crucial aspect of home comfort and health, especially in densely populated urban areas like Philadelphia. Upgrading your HVAC system can significantly improve the quality of air in your home. Here's how:

Enhanced Filtration Systems

Modern HVAC systems come with advanced filtration options that can remove a wide range of airborne particles, including dust, pollen, pet dander, and even microscopic pollutants.

  • HEPA Filters: High-Efficiency Particulate Air (HEPA) filters are among the most effective, capable of trapping 99.97% of particles that are 0.3 microns in diameter.
  • Activated Carbon Filters: These filters are excellent for removing gases and odors from your indoor air, making them ideal for urban environments where outside air might include pollutants from traffic and industrial activities.

Improved Ventilation

Upgrading your HVAC system can also involve enhancing the ventilation mechanisms, which helps in reducing indoor pollutant levels by bringing in fresh outdoor air and expelling stale indoor air.

  • Energy Recovery Ventilators (ERVs): These systems exchange the stale indoor air with fresh outdoor air, while preserving the temperature and humidity levels inside your home.
  • Dedicated Outdoor Air Systems (DOAS): These are used to bring in clean outdoor air without the energy penalties typically associated with conditioning outdoor air.

UV Light Systems

Ultraviolet light systems can be integrated into HVAC systems to destroy bacteria, viruses, and mold that might circulate through your air ducts.

  • In-Duct UV Treatment: This installation helps purify the air as it circulates through the ductwork, neutralizing airborne pathogens and allergens effectively.

Smart HVAC Controls

With smart thermostats and HVAC controls, you can monitor and control the quality of your indoor air more effectively.

  • Real-time Monitoring: Smart controls can detect changes in air quality and adjust the HVAC operations accordingly, ensuring optimal indoor air conditions.

Regular Maintenance

No upgrade can maintain its effectiveness without proper care. Regular maintenance is crucial to ensure that the upgraded components continue to function properly and contribute to improved air quality.

  • Seasonal Check-Ups: Have a professional inspect and service your HVAC system at least twice a year to ensure it is functioning optimally and maintaining the best air quality possible.


Upgrading your HVAC system presents an excellent opportunity to enhance the air quality inside your Philadelphia home. By choosing the right components and ensuring regular maintenance, you can create a healthier and more comfortable living environment. Consulting with HVAC specialists, such as those at McCorry Comfort, can help you determine the most effective upgrades for your specific needs, ensuring that your home remains a sanctuary of clean air.
