Indoor Air Quality and Home Performance
Services in Chamblee
When the average homeowner hears the term "indoor air quality," they tend to think about the temperature of their home, and maybe even the humidity levels. These are important factors of course, but not a total assessment of your home performance. Quality home performance means having a living space that has healthy, breathable air. You want to look beyond the HVAC air filter and consider your whole-house air filtration and purification options, in addition to heat and energy recovery.
