Air Quality

Poor air quality is caused by dust, dirt, moisture, debris build-up, and overly dry conditions. Having air quality comfort systems in place can prevent you from breathing in all kinds of gross pollutants like dander and bacteria, developing mold and mildew, as well as prevent irritating conditions that put you and your family’s health at risk. In fact, in-home air quality tends to be between two and five times more polluted than the air outside.

Don’t let your family suffer from home environment conditions that can cause illnesses. Make sure you have the proper air quality comfort systems installed in your home by a Cates Heating and Cooling technician.
