When the cool fall and winter weather arrive, people call Indoor Comfort Heating & Air Conditioning furnace repair experts because of a problem with their heating system. Whether it’s a commercial or residential setting, the same basic problems plague furnaces. By knowing what the most common furnace problems are, you can take proactive measures to prevent them.
Furnace Problems that Occur the Most Often
Below are the 10 most common furnace problems. Read on for advice on how to repair and fix future furnace problems.
Lack of maintenance
You fail to schedule annual furnace maintenance and inspections that could prevent unexpected problems and breakdowns. These routine inspections can help the appliance run more efficiently and reliably.
Dirty Filters
Dirty or clogged air filters reduce airflow, making a furnace work harder to circulate. In some cases, a clogged filter may damage the limit switch, which controls the fan.
Wear and tear
Normal wear and tear can cause airflow problems, heat control-related problems or even overheating.
Electric ignition or pilot control problems
A faulty ignition or pilot 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.
Malfunctioning thermostat
A faulty thermostat can lead to problems with the fan or comfort levels.
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.
Frequent cycling
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.
The furnace is too noisy
Rumbling, squeaking, and rattling aren’t normal. The sounds may indicate a mechanical problem, airflow reductions or a clogged burner.
Mechanical issues: Unless you receive training to repair furnaces, let professionals handle problems related to mechanical wear and tear. Otherwise, you may void the warranty on the appliance or accidentally cause a larger problem.
