Winter in Mesa, AZ can be surprisingly chilly, which makes your furnace essential during the colder months. It can be frustrating when you expect warmth, only to feel cold air coming from your vents. This common issue can result from several causes, some of which you may be able to troubleshoot yourself, while others require the expertise of a professional.
Check Your Thermostat Settings
The first step is to check your thermostat settings. Ensure your thermostat is set to “heat” and not “cool”, and that the fan setting is on “auto” rather than “on”. When set to “on”, the fan runs continuously, even when the furnace is not actively heating the air, which could explain the cold air you’re feeling.
Overheating Furnace
Furnaces include safety features to prevent overheating. If the system gets too hot, these features shut off the burners, but the blower may continue to run, circulating cold air. Overheating is often caused by a dirty air filter restricting airflow. Checking and replacing the filter could resolve this problem.
Pilot Light or Ignition Problems
Older furnaces with a pilot light may blow cold air if the pilot goes out. Modern furnaces with electronic ignition can experience similar issues if the ignition system fails. These problems are typically best handled by a professional technician who can safely make repairs or adjustments.
Ductwork Issues
Leaks or damage in your ductwork can allow heated air to escape before reaching your rooms or allow cold air from unheated areas to mix with warm air. While inspecting ducts can sometimes be a DIY task, repairs usually require a professional due to the tools and skills needed.
Furnace Size
A furnace that is too large for your home can also cause cold air issues. Oversized furnaces heat your home quickly but shut off before completing a full heating cycle, resulting in short bursts of warmth followed by cold air. A professional assessment can determine if your furnace is the correct size for your space.
Waiting It Out
Sometimes, what feels like cold air is simply room-temperature air circulating before the furnace reaches full operating temperature. Waiting a few minutes can allow the furnace to heat the air fully, resolving the issue.
