Why Is My Furnace Blowing Cold Air?
When the weather is cold outside, the last thing you want is a furnace that is blowing cold air. If your furnace is not giving you the heat you need, do not call in the professionals just yet. Sometimes there is a simple fix that does not require the intervention of a technician.
Before you make that phone call, here are a few things you can check to see if calling in an HVAC specialist is even necessary!
Did you just turn on your heat?
It may sound silly, but you would be surprised at the number of people who are unaware that a furnace may not blow warm are for the first few minutes of operation. Much like turning on your hot water tap, you have to give it a moment to warm up. Just as a hot water tap must expel the cold water that is already in the line before the hot water can make its way out, so too must you give your furnace a chance to warm up.
Did you check the thermostat?
If the thermostat is set to a lower temperature than the one currently in your home, then you are not going to be getting warmer any time soon. Too often an HVAC specialist is called in only to find that the thermostat has been set by one person only to have been changed by another. Sometimes the answer to keeping your house warm is just communication.
When did you last change your furnace filter?
If the filter is dirty, your furnace may be working too hard to get the job done. This can result in overheating. If your furnace begins to overheat, it may turn off the heating elements and continue to run air through to cool itself down. If you are getting cold air from your furnace, try checking the filter.
Is the pilot light on?
The pilot light is there to ensure that your heater can ignite quickly. If your heater is not igniting then that would certainly explain why you are not getting any heat.
