What follows are five of the most common reasons a furnace may blow cold air.
With most of these situations, you can probably correct the problems yourself. In other instances, though, you’ll need to call for help from an HVAC professional.
1.The Furnace Hasn’t Warmed Up – Sometimes, your furnace may blow cold air because it simply has not had enough time to warm up yet. Usually, if you just wait a few minutes, the air should begin to get warmer.
2.Your Thermostat is Set to “On” – If there’s a constant flow of cool air coming from your furnace, check your thermostat to see if the unit’s fan is set to “on” or “auto.” Make sure to set your furnace to “Auto” so that only warm air gets circulated in your home.
3. The Flame Sensor is Dirty – Pilotless ignition furnaces use a flame sensor to keep the furnace burning once it starts. If your flame sensor is dirty, your furnace will turn on and begin heating but then turn cold relatively quickly.
4. The Pilot Light is Out – If you have an older gas furnace and it’s blowing cold air, chances are the pilot light has gone out. If you’re comfortable doing so, just follow the manufacturer’s instructions for how to re-light it safely.
5. The Air Filter is Clogged – Dirty air filters are a problem because they limit airflow into your furnace. Restricted airflow can cause your furnace to run longer to heat your home until it overheats. When your furnace overheats, you will only get cold air. Changing or cleaning your Air Filters can help to solve this problem.
