Indoor Air Quality in Cambridge: what's different
Indoor Air Quality work in Cambridge 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 older homes heat with gas or oil boilers and radiators, and multi-family houses often have a separate boiler per unit. Central AC is rare in older homes, so ductless heat pumps are the most common way to add cooling and efficient heat.
The indoor air quality services Cambridge homeowners ask for most are fresh-Air Ventilation (ERV/HRV). Balanced ventilation for tight newer homes.
The City of Cambridge Inspectional Services Department issues permits, Massachusetts requires licensed gas fitters and sheet metal workers, and Mass Save offers heat pump rebates. Historic districts may review visible equipment.
