Why Is My Furnace Blowing Cold Air?
There’s nothing more frustrating than turning on your furnace during a cold spell, only to have it blow cold air. At Burleson Plumbing & Heating, we understand the importance of a warm and comfortable home, and we're here to help you figure out why your furnace isn’t heating properly. Let’s explore some common reasons this might be happening and what you can do about it.
1. Thermostat Issues
One of the simplest culprits could be your thermostat settings. If your thermostat is set to “ON” instead of “AUTO,” the fan will blow continuously, even when the furnace isn’t heating. This could result in cold air blowing through the vents. Check your thermostat to ensure it’s set to “AUTO,” allowing the fan to operate only when your furnace is producing heat.
2. Overheating
Your furnace might actually be overheating. When this happens, a safety feature kicks in to shut the burner off, preventing damage. However, the blower might continue running, pushing cool air through your home. The main causes of overheating are dirty filters, which restrict airflow and cause the furnace to work harder than necessary. Be sure to change your filters regularly to prevent this issue.
3. Pilot Light or Ignition Problems
For older furnace models, the pilot light may have gone out, causing the furnace to blow cold air. For newer models, the issue could be with the electronic ignition system. In either case, this means the furnace is not igniting properly, and professional attention is needed to ensure it’s functioning safely.
4. Leaky Ducts
Even if your furnace is working properly, leaks in your ductwork could allow cold air from unheated spaces (like your attic or basement) to mix with the warm air. This would lead to cold drafts coming through your vents. At Burleson Plumbing & Heating, our technicians are experts at diagnosing and sealing leaky ducts, ensuring efficient and effective heating.
5. Fuel Supply Problems
If your furnace runs on natural gas, propane, or oil, an issue with the fuel supply could prevent it from producing heat. For example, a gas valve could be malfunctioning, or your fuel tank could be low. In such cases, it’s best to consult with a professional to check the system and ensure everything is functioning as it should.
