Is your home feeling colder than usual this November in Glenview, IL? With the crisp autumn air giving way to early winter chills, a furnace that won’t turn on can quickly become more than just an inconvenience. It can leave you and your family shivering in your own home. If you’ve ever asked yourself, “Why isn’t my furnace working?” or “Where can I find reliable HVAC near me in Glenview?” you’re not alone. Many homeowners face this exact problem as temperatures drop and their heating systems are pushed to the limit.
In this blog, we’ll walk you through common reasons a furnace might not turn on, practical steps you can take to troubleshoot, and how to find a trustworthy HVAC professional in Glenview, IL, to get your system running smoothly.
Understanding the Glenview November Climate
November in Glenview typically brings cooler temperatures, ranging from the mid-40s to low 50s Fahrenheit during the day and often dipping into the 30s at night. According to historical weather data, residents can expect frost and occasional light snow as the month progresses. With this transition from fall to early winter, heating systems are often switched on for the first time after months of inactivity.
Because furnaces may have sat idle, it’s common to encounter minor issues or unexpected breakdowns. Preparing for these problems in advance and knowing how to respond can make all the difference in keeping your home warm and comfortable.
Common Reasons a Furnace Won’t Turn On
Before calling for help, it’s helpful to understand why a furnace may fail. Here are some of the most common reasons:
1. Thermostat Issues
Your furnace relies on your thermostat to signal when heat is needed. If the thermostat isn’t working properly or the batteries are dead, your furnace may not start.
-
Check that your thermostat is set to “heat.”
-
Ensure the temperature setting is above the current room temperature.
-
Replace batteries if your thermostat uses them.
A quick thermostat check can sometimes solve the problem without any technical expertise.
2. Power Supply Problems
Even the most reliable furnaces require power to operate. If your system isn’t receiving electricity, it won’t turn on.
-
Confirm the furnace switch is on (it’s usually near the unit).
-
Check your circuit breaker to ensure it hasn’t tripped.
-
Examine the fuse box for blown fuses.
Power-related issues are common, especially after storms or minor electrical surges, and they can be easily fixed once identified.
3. Dirty or Clogged Air Filters
Air filters are crucial for furnace efficiency and safety. A dirty filter can block airflow, causing the furnace to shut down or fail to ignite.
-
Inspect your filter monthly during heating season.
-
Replace filters when they appear dirty or clogged.
Regular maintenance like this not only prevents furnace failure but also improves indoor air quality.
4. Pilot Light or Ignition Problems
Older furnaces often use a pilot light, while modern systems rely on electronic ignition. If these fail, your furnace won’t start.
-
For pilot lights, ensure the flame is lit and stable.
-
If your furnace has an electronic ignition, listen for clicking or clicking sounds when trying to start the system.
Attempting to relight a pilot light should be done with caution. If you’re uncomfortable, it’s best to contact a professional.
5. Gas Supply or Valve Issues
For gas furnaces, the system requires a steady flow of natural gas.
-
Ensure the gas valve to the furnace is open.
-
If you smell gas, leave your home immediately and call your gas company.
Never attempt to repair a gas line yourself. Safety comes first.
6. Mechanical or Component Failures
Other causes might include malfunctioning motors, worn-out belts, or faulty limit switches. These issues are less obvious and usually require professional attention.
Regular preventative maintenance can help identify worn components before they lead to a total system failure.
Quick Steps to Try Before Calling HVAC Professionals
If your furnace isn’t turning on, there are some practical things you can try before scheduling a service call:
-
Check the thermostat settings and batteries.
-
Inspect power sources, switches, and breakers.
-
Replace dirty air filters.
-
Ensure the gas valve is open.
-
Look for error codes or blinking lights on the furnace panel.
These steps often resolve minor issues and can save time when the HVAC professional arrives, as you’ll have already ruled out basic problems.
Why Professional HVAC Service Matters
While small troubleshooting steps can help, many furnace problems require professional expertise. Attempting to repair complex systems without proper training can lead to:
-
Increased damage to the furnace
-
Safety hazards, especially with gas or electrical components
-
Higher repair costs down the line
A certified HVAC technician can quickly diagnose the problem, ensure safety, and restore comfort to your home efficiently.
According to the U.S. Department of Energy, regular professional maintenance not only extends the lifespan of your furnace but can also improve energy efficiency by 10–30%.

Seasonal Maintenance Tips for Glenview Homeowners
Preventing furnace issues before they occur is always better than dealing with an emergency in the cold. Here are some tips for November in Glenview:
-

Strange noises like banging or squealing
