Furnace Is Blowing Cold Air [Causes & Solutions]

We work with haste to find the source of your heater producing cold air and offer the best fix to the problem. Below are the most common Humble heater repairs that address cold air coming from your heater!

Thermostat Issues

The very first thing to check when your heater blows cold air is the thermostat. It’s very common for the thermostat to accidentally be on the wrong setting, and it’s a simple fix! Make sure the thermostat is on HEAT to engage the heating process. If the setting is on FAN or AUTO, fans within the system may be moving around cool air instead of warming it first.

If your thermostat is set correctly but cool air is still arriving, you’ll need a connection repair. Your heater takes directions from your thermostat, so this connection or sensor will need to be repaired or replaced to restore the connection between the two.

Dirty Air Filter

Every heater and furnace has an air filter to keep your air both warm and clean as it runs through the system. When enough particles are removed from the air, the filter will become clogged. This means it will take the warm air longer to pass through the filter, giving it a chance to cool down before entering your home.

Change out the filter to restore proper airflow and temperature. If you don’t feel comfortable making this adjustment, our technicians will be happy to show you how!

Pilot Light Is Out

If you have a furnace, then your heating system relies on combustion to heat the air in your home. The pilot light on your furnace simply indicates that the ignition process is ready and can make combustion possible. If you notice that your pilot light is out, then there is no warming happening within the furnace. You’ll need to shut down the system and relight the pilot light to ensure that the combustion chamber can be lit.

If you’re unsure how to make this happen, call on the pros. We’ll explain this process step by step for next time!

Leaking Air Ducts

One of the top sources of lost energy in your home is your air ducts. Holes, weak seals and other cracks in your air ducts allow air to escape before reaching your home. In the winter, the warm air produced by your heater has to travel through these ducts to reach your home. If there are multiple leaks, the air will escape and cool by the time it comes out of the vents. Your heater will then pump more and more air through the ductwork in an effort to warm your home, but it’s just a waste of energy.

Have a professional evaluate your ducts and repair any leaks they find. This will significantly improve your airflow and temperature accuracy in your home!
