Troubleshooting your Heating System Boiler or Furnace

Troubleshooting your heating system

You may be able to avoid a service call by checking some of the following items if your heating system is not running.

  1. Check your thermostat. First check that your thermostat is set higher than your actual room temperature. Also if you have a programmable thermostat, check that the batteries are ok if it has them and that it is set on heat not air or fan.
  2. Check that your emergency switch is on and has not accidentally been turned off. This is the red switch plate that is usually located at the top of the cellar stairs or near the near the boiler or furnace.
  3. If you are familiar with your breaker panel make sure that the breaker for your heating system is on. Call a technician for any other electrical issues beyond the breaker switch.
  4. If you have access to the burner, check that the green light near the reset button is on (if your unit is equipped with one). If the light is blinking or is off, try pushing the red reset button once. PUSH THE RESET BUTTON ONE TIME ONLY! Repeated attempts to restart the furnace could be dangerous to its relighting process and should never be done. If the furnace or boiler does not continue running on its own after the first attempt, call a technician.

Frequently Asked Questions (FAQs)

Please see our Maintenance and Service section for a detailed description of our service offerings, annual tune-up details and answers to some frequently asked questions. (FAQs)

Small leaks in your heating system, circulator pumps or plumbing fixtures can turn into a major headache if not addressed. Leaking circulators or heating pipes can damage your heating system or cause health issues.

Warm air registers should be cleaned from debris buildup that can restrict the flow of warm air from your furnace. Clean and vacuum your baseboards and registers yearly to keep air flowing over your heating registers freely. Make sure that carpeting or drapes are not blocking any heating register or radiators.

Dirty or clogged furnace filters could cause your furnace to work harder, thus reducing heating efficiency, waste money, and most importantly, cause premature failure of furnace parts or your entire furnace. Check your filter monthly during the heating season. When it is covered lightly with dust, change it. Some filters need to be changed more often than once a year, but not as often as once monthly.

Anode Rods save your water heater. The single most important factor in whether a water heater lives or dies is the condition of its sacrificial anode. Basically your anode is consumed to protect the inside exposed parts of your hot water tank from being damaged from galvanic action and mineral. Changing your anode rod before it is completely consumed is crucial in saving your hot water tank from premature failure resulting in replacement.

Never let your oil tank get below 1/4 tank and never let it run out of oil. If you run your heating system out of oil it will have to be primed manually to properly work again. Your system may also have pulled some sludge or debris from within your oil tank if it is an older tank. This sludge or debris can cause filter and nozzle damage that may require replacing these items to return your furnace or boiler to performing at its peak efficiency again. An improper spray pattern at your nozzle will cause soot build up in your heating system that will decrease efficiency and could cause air quality and health and safety issues.
