Every problem has a symptom, and frequently, it is accompanies by something you either see, hear or smell. Here are just a few examples.

Water Leaks or Rust Around your Boiler

Leaks or rust often mean that your boiler is wearing out. You should begin researching your replacement options.

Oil Odors

If your system is working properly, you should never smell fuel oil. An oil smell could come from a leak, burner or combustion troubles, heat exchanger failure or exhaust system problems. Schedule service as soon as possible.

Unusual Noises

Here are a few sounds and the possible causes. (Note: A correct diagnosis can only be made with an on-site visit by a service technician.)

Banging, whistling, howling or the sound of rushing water in your pipes.

These are common symptoms of air in the pipes, insufficient water flow or a buildup of sludge.

Booming or rumbling burner

It's normal to hear a burner "kick on," but if it makes a loud boom, which indicates a "hard start," the burner is not igniting properly. It needs to be serviced as soon as possible.

Straining sound from fuel pump

This means that there is a clog somewhere in the delivery system, for instance, in a filter or supply line.
