Recent studies reveal that indoor air can be up to five times more polluted than outdoor air. Poor indoor air quality poses significant health risks, especially for those with asthma, allergies, or other respiratory issues.

Without proper indoor air quality systems, harmful pollutants like bacteria, pet dander, dust, and allergens can build up in your air ducts, circulating contaminated air throughout your home.

At K&Y HVAC, we take a comprehensive, whole-home approach to comfort. Our team provides a range of solutions to ensure your indoor air stays fresh, clean, and safe for your family.

When was the last time you had your air ducts serviced? It's easy for particles like pollen, dust, ash, and hair to build up if neglected. These air ducts distribute the air, either heated or cooled, throughout your home
and significantly influence your home's air quality.

A unclean air duct can heighten the chances of allergens spreading in the air, potentially triggering allergies.
