There are many things that can go wrong with your furnace over the course of its life, but here are the most common problems, so you will be better prepared should they happen to you.
Call our Chicago furnace repair experts if you notice any of the following problems:
Thermostat Problems: First, if you have already checked the battery, make sure the power supply to your furnace has not been interrupted instead. If that appears alright and your thermostat still is not working, then you may need to replace it.
Noisy Furnace Problems: If you notice squeaks and squeals, there can be numerous potential reasons. Maybe the motor could be failing, or you could have an air leak in the ductwork. If you continue hearing noises, then you may have a motor problem that can only be fixed by a trained HVAC technician.
Furnace Blower Fails to Turn Off: First check the thermostat’s fan switch. If it is set to on, low, medium or high, then the fan will operate continuously. However, the “auto” setting will only operate the fan until the home is heated to the setting of the thermostat. If the blower keeps running even if the thermostat is set to “auto,” then you may have a clogged filter that has affected the limit stitch. When the temperature inside the furnace gets too high, the limit switch is supposed to turn off the fire. But clogged filters can damage limit switches easily to the point that they need replaced. This should be left to a professional HVAC technician.
Electric Furnace Ignition Problems: Open the front of the furnace, turn it on, and observe the burner. If one small flame starts, and then ignites the burners, you have an intermittent pilot system. If all the burners activate the moment you turn on the furnace, you have a direct ignition system. While this is not a problem you can fix yourself, at least you’ll know to call a trusted HVAC professional before that problem becomes worse.
