Have you ever had this problem? You turn on your heating system to find only cold air blowing. Well, there could be several reasons why your unit is not working properly. Here are some potential causes and quick fixes you should know:
Thermostat Issues
The problem may be hiding in your thermostat. It could be caused by dirt buildup, incorrect settings, or dead batteries. Here are some things to troubleshoot:
- This may sound simple but make sure it is set to “heat.” You wouldn’t believe it but this is among most of the service calls.
- Check the batteries and replace them if needed.
- Open the thermostat panel and clean your thermostat using a soft brush.
- Ensure that it is installed in the right place, not near an air vent or direct sunlight.
If none of these fixes work, it may need a replacement.
Wrong Sized System
Many homeowners assume that a bigger furnace is always better. Contrary to this belief, size does matter in this situation. An oversized system will cycle on and off, causing inconsistent temperatures. On the other hand, an undersized unit cannot effectively heat your home, which can lead to high bills. Having the right size of your heating system can make a big impact to your home’s comfort and savings. So if you need help with the sizing, reach out to your trusted HVAC company.
Clogged Filter
When your filter is clogged with dirt and other debris, it causes your unit to malfunction, blowing cold air instead of hot air. It’s also the reason why your heating bills snowball. To ensure good airflow and proper system operation, be sure to change your air filter regularly.
Leaking Ducts
Another reason why your home is freezing could be caused by clogged or damaged ductwork. Have your air duct inspected by your local HVAC contractor. It may need professional cleaning, sealing, or repair. Never take a chance to get it fixed by you or put your safety at risk, unless you’re a certified technician.
The Pilot Light is Out
If you’re using an old furnace, you may also want to check its pilot light. A gust of wind can blow the flame out. In that case, you can try to relight it by following the manufacturer’s manual or guidelines. If you’re not comfortable doing that, bring in the experts to inspect your furnace and provide you reliable solutions.
