"Dan was incredibly helpful every step of the way. He broke our estimate down for us, separating the cost to just replace the boiler and to add a radiator to one of our rooms. He also had a plan to be able to do the projects separately, if we wanted. We ended up doing everything together. It was very quick, the techs were super polite and knowledgeable. Would HIGHLY recommend."

Boiler Repair questions, answered by experts

Clean regularly, check for leaks, and schedule annual inspections for safety and efficiency.

Annual servicing, checking for leaks, and maintaining proper pressure extend the system’s life.

In most cases, repairing a radiator is more affordable than replacing it. A typical repair may cost between $100 and $200, while a replacement can average $1,500, with a range of $250 to $2,500 depending on the unit type. Radiator issues are often simple fixes for a professional, such as a blown fuse, malfunctioning thermostat, or a loose valve, and can take less than an hour. However, if the long-term costs of fixing the radiator are higher than replacement, it's better to get a new model. It is recommended to consult a heating expert to diagnose the problem and determine the best solution for your situation.

An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.

Since your boiler keeps you warm and provides hot water to your home, you’re likely to notice issues with heating in your living space right away. The most obvious sign that your boiler is breaking is not getting any heat or hot water. You might also hear some odd sounds coming from your boiler during operation, the flame in your gas boiler is not blue, the pressure is inconsistent, or your boiler is using more energy than it should. If you notice any of these signs, be sure to call a pro right away.
