Why is My Furnace Blowing Cold Air?

It is crucial to have a warm and cozy home, especially during the colder months. If you’ve ever found yourself asking, “Why is my furnace blowing cold air?” – fear not, for we’re here to shed light on this common concern and guide you towards a comfortable solution.

There are several reasons why your furnace might be delivering chilly air instead of the warmth you crave. Let’s explore some common culprits and potential solutions.

1. Thermostat Issues:

Sometimes, the root cause can be as simple as a thermostat hiccup. Ensure that your thermostat is set to the desired temperature, and consider changing the batteries if it’s been a while. A malfunctioning thermostat can lead to inaccurate temperature readings, causing your furnace to behave unexpectedly.

2. Dirty Air Filters:

Clogged or dirty air filters can obstruct the airflow, resulting in reduced heat output. Regularly check and replace your air filters to ensure optimal furnace performance. This simple maintenance task not only improves heating efficiency but also prolongs the life of your HVAC system.

3. Pilot Light Problems:

For those with older furnace models, a malfunctioning pilot light could be the culprit. If you notice that the pilot light is out or has a yellowish color, it’s time to call in a professional technician to assess and rectify the issue.

4. Fuel Supply Issues:

A furnace blowing cold air may be a sign of fuel supply problems. Ensure that your gas supply is uninterrupted and that the gas valve is fully open. If you’re using a propane furnace, check the fuel level in your tank.

5. Ductwork Leaks:

Leaky ducts can allow cold air to infiltrate your heating system, diminishing its efficiency. Our expert technicians at NORCO Heating & Air Conditioning specialize in duct inspection and sealing, ensuring that your warm air stays where it belongs.
