Boiler Repair Costs in Greater Boston

Most boiler repairs we complete fall in this range:

Average: $1,200

Low: $500
High: $3,500

What Affects the Price?

  • The parts: some boiler parts are simple and affordable to replace, especially those readily available from manufacturers. Other components, such as a heat exchanger or control board, can be more complex and may require special ordering, which can affect the price.
  • The labor: some repairs are quicker than others, depending on the part and how easy it is to reach.
  • The warranty: if your boiler is still under manufacturer warranty, some parts may be covered, though labor may not be.

You’ll get your exact price before any work begins.

Signs Your Boiler Needs Repair

  • Banging, gurgling or whistling sounds
  • Leaking water
  • Pressure loss
  • No heat or hot water
  • A pilot light that burns yellow or orange, or keeps going out
  • Frequent unexpected shutdowns
  • Unusually high energy bills

Steam and Hot Water Boilers

We repair both gas steam and gas hot water boilers. Steam systems are common in older Greater Boston homes, and they work differently than hot water systems, so we diagnose each one on its own terms.

What to Expect on a Repair Visit

  1. We call ahead. Your technician calls on the way, and even asks if you’d like a coffee or anything from the store.
  2. We arrive ready. Our trucks usually carry the parts to fix your boiler during that first appointment.
  3. We respect your home. Technicians wear shoe covers and clean up the work area when the job is done.
  4. We listen and diagnose. We ask about your comfort concerns, then do a thorough evaluation.
  5. You see your options first. We give you all your options with pricing before any work begins, and we only move forward with your approval.
  6. We follow up. After your appointment, you’ll get a short survey. Your feedback helps us keep getting better.

Repair or Replace?

We use a repair-or-replace chart that weighs your boiler’s age, the cost of the repair, your monthly utility costs, how often it has needed repairs and any comfort problems. A failed heat exchanger is the most expensive boiler repair and often makes replacement the better value. You’ll get honest information and a clear recommendation, and the decision is yours. We install Rinnai, New Yorker, Williamson and Weil-McLain boilers. See our boiler installation page for pricing and options.

Prevent Repairs With Maintenance

Many boiler repairs can be avoided with a yearly boiler tune-up. Our Trust 1 Cares membership includes annual HVAC maintenance and makes it easy to stay on schedule.

Frequently Asked Questions (FAQs)

What are the signs that my boiler may need repair?

Your boiler needs professional attention if you notice:

  • Banging, gurgling, or whistling sounds
  • Leaking water
  • Pressure loss
  • No heat or hot water
  • The pilot light is burning yellow or orange, or it keeps going out
  • Smoke or sulfurous smells coming from the boiler
  • Frequent unexpected shutdowns
  • Unusually high energy bills
Is there anything I can do to prevent boiler problems?

Yes, regular maintenance is key to preventing boiler problems. In addition to scheduling annual maintenance with our team, you can also keep an eye out for signs of trouble, such as strange noises or leaks, and address them promptly. Avoid DIY repairs and rely on professional technicians for all your boiler service needs.

How much does a boiler repair cost?

Boiler repairs typically range from about $500 to $3,500, with an average of around $1,200. The price depends on the parts, the labor involved and whether any parts are still under manufacturer warranty. You’ll get your exact price before any work begins.

What’s The Most Expensive Part of a Boiler To Replace?

The heat exchanger is the most expensive part to replace on a boiler. This is in part because the component itself costs more than most. It also requires a significant amount of labor and expertise to replace.

Most techs recommend replacing the entire boiler rather than repairing the heat exchanger. The repair price is high enough that it’s almost always more cost-effective in the long run to replace.

Is it cheaper to repair or replace a boiler?

A repair usually costs less up front, but it isn’t always the better value. We use a repair-or-replace chart that weighs your boiler’s age, repair cost, utility costs and repair history, then give you an honest recommendation.

Do you repair steam and hot water boilers?

Yes. We repair both gas steam and gas hot water boilers.

Do boiler repairs come with a warranty?

Yes. Every boiler repair is backed by a 1-year parts and labor warranty.
