Common Home Heating System Problems & Solutions!

Problem: Why is My Furnace or Boiler Not Running?

When boilers or furnaces are “not running”, it is often a simple or routine problem. One way to save money on a service call is simply to check for some of the basic issues that we encounter. Try checking these do-it-yourself solutions before calling for service:


  1. Check that safety switch is on (usually at the top of the basement stairs) and that the circuit breaker is not tripped.
  2. Check thermostat: In Heat position? Temperature turned up?
  3. Check oil tank gauge to ensure you have oil.
  4. Change the filter on your furnace.

If none of these solutions solves the problem, then call our service team to get back up and running!

Problem: Why is my Furnace or Boiler Producing a Smell and/or Soot?

Problems related to smells or other visible signs (soot or smoke) are more serious and generally require immediate attention by a trusted professional. This is particularly true if you have natural gas, as both the smell (carbon monoxide) and the combustible nature of gas, pose a threat.

With oil-fired systems, the solutions may be straightforward, such as a plugged furnace or smoke pipe. It is essential that you have your boiler cleaned yearly to prevent sooting and smells.


  1. Shut off safety switch if you use heating oil (usually at the top of the basement stairs) or call the gas company immediately if you smell gas.
  2. Have your furnace/boiler cleaned yearly.
  3. Only use heating oil that has been treated with a high-quality additive.

Problem: Why Does my Furnace or Boiler Run Continuously or Make and Excessive Noise?

Many homeowners become concerned when they notice their heating system won’t turn off or is making consistent and excessive noise. If your heating system seems to run continually, this is often a sign of furnace problems related to the motor, or may be due to a clogged filter or improper air flow.


The only real solution here is to call your local HVAC professional to accurately diagnose the noise and make the necessary repairs. It’s important for homeowners to ensure that the HVAC technicians are licensed and insured, and that the heating company has a solid reputation in the community.
