Air Quality

Air Quality Control

Indoor air quality does more than affect the performance of your HVAC system, it affects the quality of your life. The quality of the air you breathe inside your home can have a major impact on your day-to-day health. Respiratory illnesses, allergies and asthma can all be triggered by poorly filtered indoor air. Additionally, properly maintained filtration keeps your heating and cooling system running efficiently at peak performance.

Keep Your Air Clean

Proper HVAC filtration is especially critical in Southwest Florida. The warm and humid climate promotes mold and mildew growth that can infiltrate a poorly filtered system. For coastal residents, external factors such as red tide and algal blooms can also negatively impact indoor air quality.

  • Add Electronic Filtration Systems
  • Add UV Light Systems to Sanitize from the Inside Out
  • Clean Evaporator Coil, Handler & Blower Wheel

As usual a professional job well done over the years——including installation of a 4-ton York compressor and air handler that are working well in this increasingly hot atmosphere. I value consistency—-and is what Castle Air has shown. That is true professional service.
