Out of an abundance of caution about the spread of COVID-19, Columbia Gas is temporarily suspending Residential Energy Efficiency services, including home energy assessments and other efficiency services that require entering your home. We understand that will cause a delay in efficiency improvements to your home, but we believe this is a safer course of action for you, your families and the contractor network providing these services. Learn more about this decision from MassSave.

We will contact you to reschedule your home energy assessment and other efficiency services as soon as possible.
