Minimum heat requirements are part of what is called the state Sanitary Code. If a landlord does not respond to a tenant’s complaints about a Sanitary Code violation, the tenant may request that a code enforcement officer or the local board of health inspect the apartment. Find your local board of health or inspectional services department to register a complaint about lack of heat in rental property.

Options if your landlord refuses to make repairs, Mass. Legal Help, 2017. 
"If your landlord does not make repairs after you have either notified her in writing or she has been ordered by the Board of Health to make repairs, you may need to consider other options, such as withholding your rent, making repairs and deducting the cost from your rent, working with other tenants to put pressure on the landlord, taking your landlord to court, or breaking your lease."
