Common Issues That Require Furnace Repair
If you notice immediate issues with your furnace, lets get it fixed today! It’s best to turn it off before further damage is done. Give us a call at 224-558-5051 for a quick inspection.
Thermostat Issues
Often times a thermostat can fail or the batteries can die. If this happens, your thermostat won’t properly communicate with your furnace to supply heat. This can result in a non-functioning furnace or a furnace that is not running long enough to properly heat your home.
Furnace is Running But Not Blowing Through Vents
If your furnace turns on but you receive poor air flow through your vents, there could be an issue with your fans or motors. Keep your furnace off and call a technician as soon as possible so that further damage can be avoided.
My Furnace Wont Turn On
There could be a number of reasons why your furnace wont turn on at all. This would require a thorough inspection to determine the cause and resolution.
Restricted Airflow
You’ll want to regularly check your filters. Dirty or clogged filters (especially if you have pets) can result in poor airflow and restrictions that could lead into more serious problems.
Furnace Starts but Does Not Ignite
Malfunctions happen. Usually if everything cycles correctly but will not ignite, we might need to replace your igniter. These kinds of problems can be unpredictable but are easily manageable.
