WHAT WE DO

NEW SYSTEM
Whole House Air Purifiers
Whole home air purifiers work with your HVAC system to help reduce airborne particles, allergens, odors, and other contaminants throughout your property. Unlike portable units designed for individual rooms, whole-home systems provide additional filtration and purification as air circulates through your heating and cooling equipment. Cardinal Heating & Cooling installs and services a variety of air purification and filtration systems, including the Respicaire OXY 4. Our technicians can evaluate your existing HVAC equipment and help you select an air purifier suited to your indoor air quality needs.
NEW SYSTEM
Whole House Humidifiers & Dehumidifiers
Chicago’s changing seasons can create very different indoor humidity challenges throughout the year. Dry winter air may leave your home feeling uncomfortable, while excessive summer humidity can create a warm, damp indoor environment even when your air conditioner is running. Cardinal Heating & Cooling installs and services whole house humidifiers and dehumidifiers designed to work with your HVAC system for more consistent humidity control throughout your property. We can evaluate your indoor environment and recommend the right solution to add moisture in dry conditions or remove excess humidity when needed.
