FAQ

Common Questions

Key signs include rising energy bills, strange noises like banging or whistling (kettling), frequent leaks, or if your system is over 15 years old. Modern high-efficiency boilers are dramatically more reliable and less expensive to operate than older cast-iron models.
Steam boilers heat water to a boil and send steam through pipes to radiators, while hot water (hydronic) boilers circulate heated water to baseboard heaters or underfloor systems. We specialize in both and understand the unique maintenance needs of each, especially in historic MA homes.
Yes! Many modern condensing boilers qualify for significant Mass Save® rebates and incentives. Our team stays updated on the latest state requirements to help you maximize your financial savings during a new installation.
Condensing boilers are significantly more efficient—often reaching 95%+ AFUE—because they capture heat from flue gases that would otherwise be wasted. This translates to substantial energy savings and a smaller carbon footprint for your home.
