Why Is My Heater Blowing Cold Air?

December 21, 2023 | Blog

Understanding Your Heating System’s Challenges

As the winter chill sets in, a warm and cozy home becomes more than just a comfort—it’s a necessity. But what happens when your heater, instead of wrapping your Baton Rouge home in warmth, starts blowing cold air?

This is a common issue faced by many, and understanding the reasons behind it is crucial. Southern Air Heating, Cooling & Plumbing, your trusted experts in Baton Rouge, LA, are here to shed light on this perplexing problem.

Common Causes Of A Cold Air Blast

Discovering why your heater is blowing cold air is the first step to restoring your home’s comfort. Let’s explore some of the most common causes that could be affecting your heating system.

Thermostat Settings

Before diving into more complex issues, check your thermostat. It might sound simple, but sometimes the solution is as easy as adjusting the settings. Ensure it’s set to ‘heat’ and not ‘cool’ or ‘fan’.

Clogged Filters

A clogged air filter restricts airflow, causing the system to struggle and sometimes blow cold air. Regularly checking and replacing your filters can prevent this issue.

Pilot Light And Ignition Problems

For gas heaters, a faulty pilot light or ignition system can lead to cold air output. These components are important for heating the air. If they’re not working correctly, a professional heater repair might be necessary.

Ductwork Leaks

Leaky ducts can cause warm air to escape before reaching your living spaces, resulting in cold air blowing through your vents. Inspecting and sealing ductwork is a job for professionals.

When To Call In The Experts

Discovering why your heater is blowing cold air is the first step to restoring your home’s comfort. Let’s explore some of the most common causes that could be affecting your heating system.

Complex System Issues

If basic troubleshooting doesn’t resolve the issue, it’s time to call in the experts from Southern Air Heating, Cooling & Plumbing. Complex problems like a malfunctioning heat exchanger or a broken blower motor require professional heater repair or even heater replacement.

Safety Concerns

Heating systems, especially gas heaters, can pose safety risks if not handled correctly. If you suspect a gas leak or any other hazard, it’s crucial to contact professionals immediately.
