When cool weather hits, our Orange County and Los Angeles heating and air professionals are often hit with numerous phone calls by home and business owners experiencing cool air flowing from their heaters, which can definitely be frustrating. Discover some of the most typical reasons heaters blow cold air with expert insights from our Orange County and Los Angeles heating and air specialists.
A lot of people find their furnace blows out cold air when they first turn it on. This is normal since when the blower starts up, it first pushes all of the air inside the ducts out. This is unheated air and can feel cool, especially if you lack the proper insulation around the ductwork. It is normal for your heater to release cool air on startup. However, if your heater does not begin to blow warm air within a minute or so you might have an issue.
If your heater is blowing cool air, it could just be simple matter of the house temperature is warmer than the thermostat setting. It could also be that the batteries in the thermostat need to be replaced or the thermostat itself needs replacement.
Heater is Not Large Enough
If your heater is blowing cool air, it could also be that the heater is not large enough to properly heat the size of your home. If the heater is too small for your space, it will run constantly and never heat your home properly. In this case, you will need to purchase a properly sized unit.
Of course, these are just a few of the reasons a heater can blow cool air. In some models, the pilot light may be out or the filters could be clogged.
