What to look for

Signs your heating system needs attention

You don't need to diagnose it yourself — but knowing what you're seeing makes the call easier.

Some rooms never warm up

Uneven heat usually means airflow, zoning or a control problem — not necessarily a dying system.

It runs constantly, or in short bursts

Short-cycling wears equipment out fast and almost always points to a fixable underlying cause.

Banging, rumbling or squealing

Noise is information. A rumble on start-up, a bang in the pipes and a squeal from the blower are three different problems.

Heating bills climbing without a colder winter

Efficiency loss creeps in through dirty burners, bad combustion settings and duct leaks.

The burner won't stay lit

Ignition and flame-sensing faults are common and usually a same-visit repair.

It's over 15 years old and needs a big part

That's the point where repair-versus-replace math is worth running honestly.

Our work

What we do on heating

  • No-heat emergency diagnosisWe find the actual cause instead of swapping parts until something works.
  • Furnace and boiler repairIgnition, controls, circulators, zone valves, heat exchangers, venting.
  • System replacement and installationProperly sized for the house, installed so it can be serviced later.
  • Gas and oil heatBoth — including oil burner service and cleaning, which is in-house.
  • Thermostats, zoning and controlsIncluding the retrofits that finally fix the cold room upstairs.
  • Annual heating maintenanceThe fall check that keeps you off the January emergency list.

Repair or replace?

The honest answer depends on three things: the age of the equipment, what specifically failed, and how the rest of the system looks. A ten-year-old furnace with a bad igniter is a repair, full stop. A twenty-year-old unit with a cracked heat exchanger is not a repair — it's a safety issue.

Where it gets genuinely debatable is the middle: a fifteen-year-old system facing a major component. We'll tell you what the repair costs, what we'd expect the remaining life to be, and what a replacement would look like — and then it's your call, not a sales pitch. Consultations on replacement are free.

Questions

Heating questions we get a lot.

How fast can you come out for a no-heat call?
No-heat calls go to the front of the schedule, and in most cases we're out same day or next day. Call (508) 982-7953 — for an emergency the phone is much faster than the form.
Do you service oil heat?
Yes. Oil boiler and burner service, cleanings, and oil tank work are all handled in-house — a lot of Greater Boston housing stock still runs on oil.
Can you fix a cold room without replacing the system?
Often, yes. Uneven heat is usually a duct, balancing or zoning problem, and those are fixable without touching the equipment.
Is a consultation on a new system free?
Yes — consultations and estimates on new systems and larger projects are free.

Talk to the people who'll do the work.

Frankie and Hans answer their own phones. Tell them what's going on and they'll tell you straight what it takes to fix it.
