You’ve turned on the furnace and you expected to be greeted with warm air, but that didn’t happen. Instead, you were greeted with cold air. What could be the reason for this unexpected occurrence? Keep reading to find out some possibilities.
The Air Filters are Dirty
As air moves through the exchanges and into the gas chamber, the air goes through the system’s filter. If your filters are clogged or otherwise dirty, it can be difficult for air to enter the chamber. The chamber is where the air is heated up so if something is affecting the airflow into the chamber, that could be the reason why you’re experiencing cold air.
Interrupted Gas Supply
Check to see if your furnace’s pilot light is off. If it is off, that means that there’s a problem with supplying gas to the furnace. When that happens, the air isn’t heated and you experience cold air. You can fix this by following the instructions in your owners manual on how to relight your furnace’s pilot light. If it doesn’t relight after following those directions, it’s time to contact an HVAC Company in Perry Hall, MD to look at your furnace.
Dirty Flame Sensor
Your furnace’s flame sensor tells your heating unit to turn on and warms the air that cycles through. If it’s dirty, it may not realize that your burners have turned on. You can do a test to see if this is the case. Simply turn it off then on again. If the air feels warms for a moment but then turns cold, it’s a good indication that your flame sensor is dirty.
Something Wrong with the Thermostat
Sometimes it’s something as simple as someone else in the home adjusting the thermostat without you knowing. Other times, there can be something wrong with the thermostat itself. When was the last time you put batteries in it? Is it properly programmed? Take all of these things into account when trying to figure out the cause for cold air.
