Furnace Repair in Greater Boston & the South Shore

Furnace Repair Costs in Greater Boston

Most furnace repairs we complete fall in this range:

What Affects the Price?

• The parts: some parts are simple and affordable to replace, while others, like a control board or major component, cost more and may need to be special ordered.
• The labor: some repairs are quicker than others, depending on the part and how easy it is to reach.
• The warranty: if your equipment 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.

Common Furnace Problems We Fix

• Heat that comes and goes: the furnace kicks on and off at odd times, leaving your home unevenly heated.
• Flame rollout: the furnace isn’t burning fuel properly and flames can escape the burner area. This is a safety issue that needs attention right away.
• Failed safety components: flame sensors, ignitors, gas valves, high limit switches and related parts.
• Bad thermostats.
• Leaks on high-efficiency furnaces: these furnaces produce water that drains through a condensate line. Without regular service, the drain clogs and water backs up into the furnace.
• Failed inducer motors: the inducer pushes combustion gases, including carbon monoxide, out through the chimney or vent pipe.
• Bad control boards.
• Failed blower motors: the motor that moves warm air through your home.

Is Your Furnace the Right Size?

We see a lot of furnaces that are too big for the home. An oversized furnace short cycles, turning on and off over and over, which wears it out early and drives up your energy bills. A furnace that’s too small runs almost constantly and struggles to keep up. A properly sized furnace runs in steady, even cycles and turns on and off in step with your thermostat. If repeated breakdowns or high bills point to a sizing problem, we’ll explain what we find.

Safety Checks on Every Call

Every furnace repair visit includes a heat exchanger inspection and a carbon monoxide test. It’s part of our checklist, every time.

If We Find a Cracked Heat Exchanger

A cracked heat exchanger can let carbon monoxide into your home, so we treat it seriously:

• We show you exactly where the crack is.
• We ask you to sign a form acknowledging that the heat exchanger is cracked and dangerous.
• We place a red tag on the furnace noting that it’s unsafe to operate.

Our cracked heat exchanger guarantee: we’re so confident in our process that if you get a second opinion and they don’t find a crack, we’ll replace your furnace for free. We’ll just make one more visit to double-check first.

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 furnace 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, including safety checks.
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 furnace’s age, the cost of the repair, your monthly utility costs, how often it has needed repairs and any comfort problems. A cracked heat exchanger or carbon monoxide concern changes the conversation, because safety comes first. Either way, we’ll give you honest information and a clear recommendation, and the decision is yours. If replacement makes sense, see our furnace replacement options.
