Furnace Tips and Advice for Heating Repairs
Check the Battery In Your Thermostat
If it seems as if your furnace doesn’t produce any heat, check the battery level in the thermostat. In some models, simply replacing the battery may do the trick.
Change the Air Filters
Dirty air filters lead to a multitude of furnace problems. Clean or replace the filter once a month, according to the manufacturer’s directions. One of our furnace repair professionals can show you how to do this.
Most Common Furnace Problems
Whether it’s a house or commercial building, the same basic problems plague furnaces in Illinois. Below are some of the most common furnace problems we see in Illinois as well as common causes.
The Furnace Blows Cold Air
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.
Rumbling, squeaking, and rattles aren’t normal. The sounds may indicate a mechanical problem, airflow reductions, or a clogged burner.
Cycling between the “On” and “Off” modes may indicate a clogged filter, improper airflow, or a bad thermostat setting.
A faulty thermostat can lead to problems with the fan, causing uncomfortable temperature levels.
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.
