When the biting cold of a Winnetka winter sets in, a reliable furnace is the most important appliance in your home. It’s the key to keeping your family warm, safe, and comfortable. So, when it starts making strange noises, blowing cold air, or refuses to turn on, it’s a problem that needs to be addressed immediately. Finding a fast, trustworthy, and skilled solution is essential. But what do these common furnace problems mean? And how do you choose a local repair service that you can trust to work on such a critical piece of equipment? This guide will walk you through what you need to know about furnace repair services in Winnetka. We'll cover the most common furnace problems, a few simple things you can check yourself, and how to choose the right local expert to get your system back up and running safely. Common Furnace Problems You Shouldn't Ignore Your furnace will almost always give you clues before it fails completely. If you notice any of the following, it’s time to call a professional for a diagnosis. 1. The Furnace Won't Turn On This is the most obvious sign of a problem. If your thermostat is set to "heat" and nothing happens, the issue could be related to the power supply or the thermostat itself. It might be a simple tripped circuit breaker or dead thermostat batteries. However, it can also indicate a more serious problem, such as a faulty safety switch, a bad transformer, or a problem with the main control board. 2. The Furnace is Blowing Cold Air If the fan is running but the air coming from your vents is cool or lukewarm, it can be frustrating and alarming. Common causes for this issue include: A Dirty Air Filter: A severely clogged filter can restrict airflow over the heat exchanger, causing it to overheat and shut off as a safety measure, while the fan continues to blow cool air. An Extinguished Pilot Light: For older furnaces, the pilot light may have gone out and needs to be relit. Burner or Ignition Issues: For modern furnaces, a problem with the electronic igniter or the gas burners will prevent the furnace from producing heat. 3. The Furnace is Making Strange Noises Loud banging, scraping, or squealing sounds are not normal and should be investigated immediately. Banging or Booming: A loud bang when the furnace kicks on can indicate a delayed ignition problem, where gas builds up before it lights. This can be dangerous and needs to be addressed. Squealing or Grinding: These high-pitched sounds often point to a problem with the blower motor, such as worn-out bearings or a failing belt. Ignoring this can lead to the motor burning out completely. 4. The Pilot Light is Yellow A healthy pilot light should be a steady blue flame. If your pilot light is yellow or flickering, it is a serious safety issue. This is a sign of improper combustion, which could mean your furnace is producing carbon monoxide. If you see a yellow pilot light, turn off your furnace immediately, ventilate your home, and call a professional.
