Indoor Air Quality in Madison: what's different
Indoor Air Quality work in Madison follows the local climate. Long heating seasons dry indoor air and tight homes can trap pollutants. Humidification, ventilation and sealed ducts in basements and attics are common improvements.
Most homes have basements with gas furnaces or boilers, and central AC is common in newer homes. Older homes may have hot-water radiators and limited ductwork, making ductless systems a popular upgrade.
The indoor air quality services Madison homeowners ask for most are whole-Home Humidifiers. Bypass and steam humidifiers for dry winter air.
The City of Madison Building Inspection Division issues mechanical permits, and Wisconsin licenses HVAC contractors through the Department of Safety and Professional Services. Focus on Energy offers incentives for qualifying equipment.
