Decision

Repair or replace?

Replace when the boiler is 20 to 25 years old or more, breaks down repeatedly, has a cracked heat exchanger or venting problems, or a repair approaches half the price of a new one. Mass Save has discontinued rebates for new gas, oil and propane heating equipment purchased after its 2024 deadline and focuses on heat pumps [VERIFY AGAINST OFFICIAL SOURCE].
