Common Problems with Oil Heaters

Corrosion and Mineral Build-up
The fuel line that connects your oil tank to the furnace can easily become blocked. The best way to prevent blockages is to make sure that you don’t run out of oil. If you notice a buzzing or clicking sound with the furnace is on, check to see if the fuel line is bent or has sludge, mud, or rust on it.

Rust can cause oil to seep out and minerals to build up, which provides less fuel to your burner, clogs your fuel line, and reduces heat circulation in your home. Call one of MGM Mechanical’s experienced technicians to assess the issue and make any necessary repairs.

Faulty controls
Control issues prevent your oil furnace from receiving signals that allow it to function properly. An MGM Mechanical HVAC professional should handle any electrical issue related to your heating system.

Smoking burners and strange noises
If you notice smoke or strange noises including hissing or gurgling sounds coming from your oil furnace, turn it off and call one of our HVAC professionals immediately. Smoking could indicate a clogged nozzle or misplaced burner. Unusual noises may indicate that your boiler needs repair sooner rather than later and could lead to larger issues if not addressed immediately.

Things to check if your boiler isn't working

Check that the burner has fuel and power

  • Make sure you haven’t run out of oil and that the power switch for the burner is on.
  • If you have oil and the switch is on, check your circuit breaker to make sure the breaker wasn’t tripped.

Look at the thermostat

  • If your thermostat is set too low, your boiler may not start.
  • Turn up the temperature setting and your system should start up again.

Clogged ductwork

  • Check your system’s ducts for any clogs.
  • Clear out any clogs and replace the filter.

If your home’s oil-boiler heating system still isn’t working, don’t wait; call MGM Mechanical. We’ll have one of our friendly heating specialists diagnose the problem and get your heater back up and running the first time.

How your oil heating system works

Your oil heating system can distribute heat in one of three ways – pushing warm air through vents, running hot water through baseboards, or sending steam through radiators.

When your thermostat senses that the temperature of your home has fallen below the thermostat setting, it sends a signal to your heating system to heat your home. When engaged, oil travels from a storage tank to the oil burner where it becomes a fine mist that mixes with air and is ignited in the combustion chamber of your burner. Your home’s heating system then works to distribute that heat throughout your home depending on the type of system you have.

Water-based systems (hot water or steam) heat the water in a cast iron or steel boiler and then send it through your home. A hot water system circulates hot water through radiators or baseboards, while a steam system turns water into steam that passes through pipes to the radiators.

In a warm air system, a blower sends the heated air from your furnace through ducts and out of vents in your floors or walls. Cooled air passes through a return duct and goes back to the furnace and repeats the cycle.

If you notice that your home’s oil heating system is not operating at its best, contact MGM Mechanical to get your oil furnace back to running at peak performance.
