Winter chills can be uncomfortable, especially before work in the morning. The best feeling in these cold winter months is to wake up nice and toasty thanks to an efficient heater, but what happens when that heater starts to chill your house? If your heating system is suddenly blowing out cold air, here are some of the reasons why!

Lack Of Cleaning

Cold air coming from a heating system can be linked to a lack of cleaning because the build-up of dirt and grime can be detrimental to your system’s air filters. When air filters become congested with dust and dirt, this can overheat your furnace, causing HVAC malfunctions.

Avoid a chillier than usual morning this winter by taking the time to clean and replace your air filters! The key with air filters is to replace or clean them roughly every two to three months to avoid malfunctions or strain on the HVAC system.

Check The Thermostat

Have you checked if your thermostat is set to heat? We know that may be the first thing you check, but you would be surprised by the number of homeowners that accidentally forget to set their thermostat to heat and get cold air instead of warm air.

However, if you have your thermostat set to heating your home and still are experiencing a sudden chill, you may have issues with your thermostat’s wiring. Thankfully thermostat malfunctions can be fixed easily with a proper technician.

Air Duct Leaks

Air ducts with leaks can be a significant factor in messing with your home’s general airflow and temperature, which can interfere with your ability to stay cozy this winter. Leaks in your air ducts can cause warm air to escape your home and lead to uneven heating that impedes the general airflow of your home.

When it comes to fixing air duct leaks, you will need to call a professional to help seal those leaks. Air leaks can be tricky to spot without the proper equipment, so don’t try to DIY this project and leave it to the pros.

Check The Pilot Light

Often, homeowners will have a heating unit that uses a pilot light for gas-powered heating systems. If your pilot light goes out, you will begin to notice a heating system that blows cold air, but thankfully the issue can be resolved by relighting your system’s pilot light.

There can be numerous reasons why your heating system suddenly begins to malfunction, but the best thing to do is to schedule maintenance with a team of professionals immediately, and
