Why Is My Furnace Blowing Cold Air?

December 19, 2023 | Blog

Understanding Your Furnace’s Challenges

When winter’s chill sets in, a warm, cozy home is what we all desire. But what happens when your furnace — the heart of your home’s heating system — starts blowing cold air instead of warmth?

This is a common issue faced by many homeowners in College Station, TX, and Barker’s Heating & Cooling is here to shed light on this problem. Understanding why your furnace is underperforming is the first step towards a solution.

Common Causes Of A Cold Air Furnace

Discovering why your furnace is blowing cold air is crucial in determining the right course of action. Various factors, ranging from simple oversights to more complex mechanical issues, can contribute to this problem. Let’s explore some of the most common causes that could be affecting your home’s heating system.

Incorrect Mode Or Fan Setting

One of the simplest reasons your furnace might be blowing cold air is due to incorrect thermostat settings. Ensure your thermostat is set to ‘heat’ and not ‘cool’ or ‘fan’. The ‘fan’ setting, while circulating air, doesn’t necessarily produce heat.

An Unlit Pilot Light

For older furnaces, an unlit pilot light can be a common culprit. If the pilot light goes out, the furnace can’t heat the air, resulting in a malfunctioning heater.

Safety Switch Activation

Modern furnaces come equipped with safety switches that shut off the burners if overheating is detected. This can lead to the fan blowing without heated air.

Dirty Air Filters

Clogged air filters can restrict airflow, causing the furnace to overheat and, as a result, blow cold air. Regular maintenance is crucial to prevent this issue.

Faulty Ignition System

Newer furnace models with electronic ignition systems can face issues if the ignition fails. This can also prevent the furnace from creating heat.

Solutions: Repair, Maintenance Or Installation

When your furnace is blowing cold air, it’s important to consider all possible solutions. From simple repairs to complete system overhauls, the right approach depends on the specific issue at hand. Barker’s Heating & Cooling offers a range of services to address each of these challenges.

In cases where your furnace is old or repairs are too frequent, considering a new heating installation might be more cost-effective. Upgrading to a more efficient system can provide long-term benefits for your home.

To ensure your furnace consistently provides warm air, preventative measures are essential. Regular maintenance not only extends the life of your heating system but also enhances its efficiency and reliability.

What Our Customers Are Saying

Very Professional

Chandler did an excellent job checking out our heat pump. He was very professional, communicated well, was responsive to our questions and I was very happy with everything he did.

Steve M.

Honest and Trustworthy

Our AC went out during a late summer heatwave. Called Barkers and Victor worked very hard to get the outside unit up and running. Two hours later we conceded to the death of a 29 yo unit. Victor notified the office the next morning, and within 24 hours we had a complete new system installed, and the house cooled by the time I got home from work. Highly recommend. Honest and trustworthy.

Susan H.

Very Impressed

We were impressed by this company from the first phone call. Reed was an exceptional young man; very personable and professional. The installation team of Mike, John and Cody did an excellent job. Barker’s is a business with high standards and we are very satisfied with everything about them. So glad we found this company!
