Why Is My Alton, IL Home’s Heater Blowing Cold Air?

Thermostat has the Wrong Setting Causing It To Blow Cold Air When you are finally in your Alton, IL home from a long workday in the winter, the first thing that we all want to do is get snuggled in from the long day. One thing that we may not expect to happen is our heater blowing out cold air. This can be so frustrating and very confusing. Heaters are supposed to shoot out hot air and not cold air! Why is this the problem, and should you be thinking about getting a new heater? Continue reading on to find out what you may need to do!

Your Thermostat Has the Wrong Settings On

Thermostats allow Alton, IL homeowners to stay comfortable with ease. However, these devices can run into some problems at some point. If you have a heater blowing cold air instead of hot, your system could be set incorrectly. This is something that is common and could happen to the best of us. The best thing to know is that this isn’t a make-or-break problem. Just make sure to set it to the appropriate setting.

The heater Has a Dirty Air Filter

Your air filter is a very important piece of your system. When these pieces are clean, these filters provide fresh air for your home. However, if these happen to be dirty, it is harder for your system to work. If a filter is too dirty, it blocks airflow and overheats the furnace. This could cause problems down the road that are more expensive than simply cleaning out your air filter.

Your Heater System Has Overheated

Dirty Air Filters When a furnace only blows cold air, there could be a chance that the heater could have overheated. This doesn’t mean the heater is broken, but it could mean there is dirt buildup, your system is old aged, or there is a mechanical failure within your system.

Leaky Air Ducts

Your HVAC system will usually include air ducts, which are then scattered throughout your home. If you are experiencing cold air, this could mean that your air ducts are leaking. If this does happen, it is best to leave the issue to the professionals. Finding a leak can be hard enough, but sealing it is a challenge, make sure to make an appointment with our team at B & W Heating and Cooling to ensure the leak is fixed and your air is running perfectly.
