When you turn on your furnace, the last thing you expect is for it to blow cold air. It’s not just frustrating—it’s also a clear sign that something isn’t working properly. If you’re in Oakland County, MI, and dealing with this issue, don’t worry. At Kotz Heating, Cooling & Plumbing, we’re here to help. Let’s look at why your furnace might be blowing cold air and what you can do about it.
Common Reasons Your Furnace Is Blowing Cold Air
Your furnace is designed to keep your home warm and cozy. If it’s failing to do that, one of these common problems could be the culprit.
Incorrect Thermostat Settings
It might seem too simple to be true, but sometimes, the issue is your thermostat. If the thermostat is on the “fan” setting, the furnace will blow air that feels cold. Switch the setting to “auto” so that the fan only runs when the furnace is actively heating.
A Clogged Air Filter
Air filters trap dust and debris to keep your furnace running efficiently. However, if the filter is clogged, airflow is restricted, and the furnace may overheat. This can trigger a safety feature that shuts off the burner, leaving the fan to blow unheated air. Replace your air filter regularly to avoid this issue.
Ignition Problems or Pilot Light Issues
For gas furnaces, a pilot light or ignition system is critical. If the pilot light goes out or there’s an ignition system failure, the furnace won’t produce heat. You can try relighting the pilot light (if your furnace has one), but if it doesn’t stay lit, it’s time to call a professional for heating repair.
Dirty or Faulty Flame Sensor
The flame sensor detects whether your furnace’s burner is working. If it’s dirty or malfunctioning, the furnace may shut down the burner while the fan continues to run. Cleaning the flame sensor might solve the problem, but this task is best left to an experienced technician. Schedule a heating repair with Kotz today!
Low Fuel or Gas Supply
If your furnace uses natural gas or propane, insufficient fuel can cause it to blow cold air. Check that your gas supply is on and that your propane tank has enough fuel. If everything checks out, there could be a bigger issue with your gas line that requires professional attention.
When to Call for Professional Heating Repair
While some furnace issues can be resolved with a quick DIY fix, others need a professional touch. Here’s when you should reach out to Kotz Heating, Cooling & Plumbing.
Persistent Cold Air
If your furnace continues to blow cold air after checking the thermostat, air filter, and pilot light, it’s time to call for expert heating repair. A trained Kotz technician can identify and resolve complex issues like faulty sensors or gas valve problems.
Unusual Noises or Smells
Strange noises or unpleasant odors coming from your furnace can indicate serious issues, such as mechanical failure or a gas leak. These situations require immediate professional attention to ensure your safety.
Frequent Cycling On and Off
A furnace that turns on and off repeatedly, known as short cycling, is not only inefficient but can also lead to more extensive damage. This issue is often caused by dirty components, thermostat problems, or overheating. Schedule heating system maintenance with Kotz Heating, Cooling & Plumbing.
Preventing Furnace Problems
The best way to avoid your furnace blowing cold air is by taking proactive measures. Here’s how you can keep your heating system running smoothly.
Schedule Annual Maintenance
Regular maintenance is key to a well-functioning furnace. Kotz Heating, Cooling & Plumbing offers professional tune-ups to clean, inspect, and optimize your system. This helps catch minor issues before they become major problems.
Change Air Filters Regularly
Replacing your air filter every one to three months can prevent clogs and maintain proper airflow. A clean filter also improves energy efficiency and indoor air quality.
Keep Your Vents Clear
Blocked vents can restrict airflow, causing your furnace to work harder than it should. Make sure furniture, curtains, and other objects aren’t obstructing your vents.
