Whether your furnace runs on gas or electricity, it should produce warm air when functioning normally. Read on to learn about common reasons that your furnace would blow cold air into your home in Lincolnshire, IL.
Faulty Igniter
In a gas furnace, the igniter is usually a piece of ceramic inlaid with metal that gets red hot. At that temperature, it ignites the gas. Some igniters use a spark-creation system instead of simply getting hot. Generally, the most common problem is when the igniter cracks for some reason.
Bad Coils
In an electric furnace, the coils create the heat. The system is reminiscent of a large electric hair dryer. If the coils don’t function, the blower motor will move cold air around.
Something Wrong With the Pilot Light
Older gas furnaces will have a pilot light rather than an igniter. In many cases with these older systems, cold air is most often the result of damage to the pilot light. Other times, it could simply be that the light has gone out for some reason.
Thermostat Issues
This problem could affect both kinds of furnaces and is quite easy for one of our professional technicians to repair. We can replace the thermostat, and you might want to upgrade to a smart thermostat to save energy.
Leaking Ducts
Again, this can be a problem with either kind of furnace. When you have such leaks in your ductwork, the hot air seeps out before it gets to the registers in your home. One of our professional technicians will be able to do a few tests to determine whether this is your issue.
