Lack of Maintenance
Schedule annual furnace maintenance and inspections to prevent unexpected problems and breakdowns. These routine inspections can help your furnace run more efficiently and reliably.
Dirty or clogged air filters reduce airflow, making a furnace work harder to circulate. In some cases, a clogged filter may damage the switch that controls the fan.
Wear and Tear
Normal wear and tear can cause airflow problems, heat control-related problems or even overheating.
A faulty thermostat can lead to problems with the fan, causing uncomfortable temperature levels.
The Furnace is Too Noisy
Rumbling, squeaking and rattles aren’t normal. The sounds may indicate a mechanical problem, airflow reductions or a clogged burner.
The Furnace Doesn’t Heat at All
A furnace that doesn’t perform its main task may have problems with the thermostat setting, power, gas or the pilot light.
The Furnace Doesn’t Heat Enough
In addition to a clogged filter, a furnace may not produce enough heat if it’s the wrong size for the space.
Cycling between the “On” and “Off” modes may indicate a clogged filter, improper airflow or a bad thermostat setting.
The Blower Continuously Runs
Blower issues may indicate a problem with the limit switch, which a professional may need to replace.
Electric Ignition or Pilot Control Problems
A faulty ignition or pilot light could make it difficult to heat a home or commercial space. Thermocouple problems, drafts or clogs in the appliance may result in an unlit pilot light.
