Sound Familiar?

  • Radiators barely warm, or cold at one end of the house
  • No heat and no hot water
  • Banging, gurgling, or whistling at startup
  • Pressure gauge that keeps dropping
  • Water pooling near the boiler
  • Boiler firing and shutting off over and over

Any of these gets a real diagnosis from a licensed boiler technician, not a guess and a parts swap.

Boiler Replacement

New boiler installation may be worth discussing in some cases. Upgrade to a high-efficiency boiler that saves on energy bills and enhances your home’s comfort.

Boiler Tune-Ups and Annual Maintenance

A boiler tune-up before the cold sets in helps catch problems early, reduces the risk of an unexpected breakdown, and helps the system run more efficiently all season. Here is what our boiler technician checks:

  • Operating pressure and temperature against manufacturer specs
  • Heat exchanger for cracks, corrosion, and scale
  • Circulator pump, expansion tank, and pressure relief valve
  • Low water cutoff and other safety controls
  • Flue and venting for blockage or draft problems
  • Ignition, gas pressure, and thermostat and zone valve response
  • Air trapped in radiators or zone

Fall boiler inspection slots fill up fast. Annual boiler maintenance is also included for Efficient Comfort Club members.

FAQS About Boiler Repairs

It depends on the age of the unit and the specific failure. A newer boiler with a bad pump is worth repairing. An older one with a cracked heat exchanger or repeat repairs is worth a boiler replacement conversation. We will price both so you can decide.

Usually trapped air, scale buildup, or a circulation problem. Bleeding the zones sometimes fixes it. If the noise sticks around or comes with weak heat, get a boiler inspection before it grows.

Most pressure loss comes from a leak, a failing expansion tank, or air that needs bleeding. Refilling without finding the cause is temporary. A technician can pressure-test the system and locate the source.

A properly tuned boiler generally runs more efficiently than one that has gone years without service, which may help reduce energy costs. Results depend on your system and home. Maintenance can also help reduce the risk of surprise breakdowns mid-winter.
