Why Is My Furnace Blowing Cold Air?

January 15, 2024 | Blog

How Do You Fix A Heater That Blows Cool Air?

At Ace Air Conditioning & Plumbing in Lake Charles, LA, we understand the discomfort and concern that occurs when your heater is blowing cold air. This common issue can arise from various causes, each requiring a specific solution.

In this comprehensive guide, we’ll explore what causes your heating system to blow cold air. Our team is here to offer effective solutions to ensure your unit functions efficiently, keeping your home warm and comfortable.

Furnace Heating Up: Normal Operation Or Delayed Heat?

It’s normal for heating systems to take a short period to heat up. However, if your unit takes more than 15 minutes to produce hot air, it’s time to schedule an inspection with Ace Air Conditioning & Plumbing.

Prolonged heating times can indicate issues like ignition problems or malfunctioning internal components. These problems require professional attention to restore heating.

Causes For A Heater Blowing Cold Air

A heatless heating system is a cruel oxymoron. It’s also an uncomfortable inconvenience many Lake Charles homeowners have experienced. Understanding what causes your unit to blow cold air will help you determine when to contact our team for assistance.

Incorrect Thermostat Settings

Incorrect thermostat settings can cause your system to blow cold air. Check your thermostat and determine it’s set correctly. Switching the setting to “AUTO” allows your furnace to produce heat, preventing continuous cold airflow.

Pilot Light Issues

In older furnaces, an extinguished pilot light can cause cold air output. Follow your heater’s manual to safely reignite the pilot light. Persistent issues might indicate a faulty thermocouple or control valve.

Damaged Ductwork

Damaged or leaky ductwork can lead to significant heat loss. Have one of our professionals check your ducts for any signs of damage. Repairing air duct leaks can significantly improve heating efficiency and prevent cold air from seeping in.

Furnace Short Cycling

Many individuals have experienced the burnout that comes from overworking themselves. Your heating system experiences the same thing!

Dirt buildup, airflow restriction and a lack of upkeep can cause it to short cycle. Your system will operate at irregular times and may produce cold air.

Regular maintenance, including cleaning internal components and replacing air filters, is crucial. If short cycling occurs, it’s essential to seek professional assistance as it can indicate more serious issues.

Dirt And Grime Buildup

An accumulation of dirt and grime on the flame sensor can lead to inefficient heater operation. Regular cleanings and timely filter replacements are also essential. A clean system operates more efficiently and is less likely to blow cold air.

Additional Tips For Furnace Efficiency

Before reaching out to Ace Air Conditioning & Plumbing to schedule furnace repair, there are several steps you can take to enhance your unit’s efficiency:

  • Upgrade your insulation — Improving insulation can reduce the workload on your furnace. This will enhance its efficiency and lifespan.
  • Clean air vents — Ensure all vents aren’t blocked by furniture or curtains. Clean them to maintain adequate airflow.
  • Seasonal maintenance checks — Schedule maintenance with our team to determine all components are functioning correctly.

Implementing these tips can significantly improve the performance of your furnace. They can extend their lifespan and reduce the likelihood of cold air issues.

What Our Customers Are Saying

Friendly and Honest

Technician came out to my house within an hour of calling and he was very friendly and honest. I was expecting to have to replace the whole unit or have a salesman try to have me “upgrade” to a newer unit but Mr Jeff was quick to diagnose and correct the problem at a reasonable cost.
