Must-know "My furnace is running but blowing cold air. Who can I call for service in the Roseville area?" terms:
It is a confusing sensation: you hear the hum of your HVAC system, you feel air coming out of the registers, but instead of a cozy warmth, it feels like an air conditioner is running in January. When a Furnace Blowing Cold Air becomes a reality in your home, several mechanical or settings-based issues could be at play.
One of the most frequent culprits is a simple pilot light failure or an ignition issue. If the furnace cannot light the burners, the blower fan will still move air, but that air will never be heated. Additionally, a dirty flame sensor can be a major headache. This small component detects whether a flame is present; if it is covered in soot or grime, it tells the system to shut off the gas as a safety precaution, leading to a Furnace Blowing Cold Air even though the fan keeps spinning.
Before you assume the worst, we always recommend checking your thermostat. It sounds simple, but many service calls in the Roseville area are resolved just by toggling a switch. If your fan setting is set to "ON" instead of "AUTO," the blower will run 24/7. This means that even when the furnace isn't actively heating water or air, the fan is still pushing room-temperature air through your house, which feels like a cold draft.
For residents in the neighboring areas, following Granite Bay Heating Cold Air Tips often starts with ensuring the thermostat is set to "HEAT" and the fan is on "AUTO." This ensures the fan only blows when the burners are actually firing.
Another common scenario involves the furnace overheating. This usually happens because of restricted airflow—often caused by a neglected air filter. When the internal temperature of the furnace gets too high, a safety device called a "high-limit switch" trips. This kills the burners to prevent a fire but keeps the fan running to cool the unit down.
If you find yourself looking for Folsom Heating Cold Air Tips, a clogged filter is the number one cause of "short cycling" and cold air blasts. The system is essentially gasping for air, getting too hot, and shutting down its heating capacity to protect itself.
If you are asking, "My furnace is running but blowing cold air. Who can I call for service in the Roseville area?", you might want to try a few DIY checks first. You could save yourself a service fee with these simple steps:
If you've tried these and still have no heat, it’s time to consult a guide like Heating Blowing Cold Air in Auburn CA or call us for a professional look.
Older furnaces use a "standing pilot"—a small, constant flame. If this goes out, your furnace won't light. Newer models use electronic ignition or a hot surface igniter. If you hear a clicking sound but no "whoosh" of flames, your igniter might be cracked. This is a common part of Furnace service Roseville CA, where we inspect the thermocouple and ignition sequence to ensure everything is firing correctly.
Airflow is the lifeblood of your HVAC system. If your home has "dead zones" where air feels colder, check for blocked returns. Dust accumulation in the ductwork can also impede efficiency. Proper Heating service Roseville CA includes checking that the entire "breathing" system of your home is clear of obstructions.

The question "My furnace is running but blowing cold air. Who can I call for service in the Roseville area?" eventually leads to a bigger decision: is it worth fixing again? Most furnaces have a lifespan of 15 to 20 years. If your unit is approaching two decades of service and starts blowing cold air, it might be a sign of a failing heat exchanger—a serious and often expensive issue.
If you find yourself asking, "Need your system replaced?", consider the frequency of your repairs. If you've called for service three times in the last two years, the money spent on repairs could have been a significant down payment on a modern, high-efficiency system.
The fifteen-year threshold is a major turning point. Beyond this age, parts become harder to find, and efficiency drops significantly. A cracked heat exchanger isn't just a repair issue; it's a safety hazard that can leak carbon monoxide into your home.

Modern HVAC technology has come a long way. Today's "sophisticated adaptive systems" can adjust their heating capacity based on the weather outside, meaning they don't have to run at 100% power all the time. This leads to more stable temperatures and lower energy bills. Plus, Roseville residents can often qualify for federal tax rebates of up to $2,000 on qualified equipment, making an upgrade even more attractive.
