Top 8 Reasons Why Your Furnace Is Blowing Cold Air

If you are worried about your furnace blowing cold air, consult our furnace repair Red Deer.

Take A Look At These 8 Of The Most Prevalent Causes:

Filters That Are Clogged.

If your furnace’s air filter is coated with dust, grease, or soot, replace it. Problems caused by a blocked filter include extended heating cycles and overheating. Your furnace will blow cold air throughout the home due to the system overheating.

A Pilot Light That has Been Damaged.

The thermocouple detects a reduction in temperature when the pilot light goes out and alerts the gas valve to shut. The most typical cause of a failing pilot light is a defective thermocouple. Your furnace will blow cold air under such circumstances.

A Clogged Flame Sensor.

A pilot flame sensor assures a successful heating cycle by sensing the heat generated. If the furnace is clogged with dirt and grime, it will rapidly lose heat and blow cold air.

Condensate Lines Clogged.

Excess moisture is removed using condensate lines or drain lines. If the pipe becomes clogged, the burners will become inactive, causing your furnace to blow cold air and Ductless AC Red Deer, Lacombe, Sylvan Lake, and surrounding areas.

Incorrect Temperature Settings.

When your thermostat is set to “ON,” your furnace will run even if it is not providing heat. It also can cause your furnace to blow cold air. Therefore always keep the thermostat in “AUTO” mode.

The Gas Supply is Running Out.

Your furnace will most likely be unable to provide heat if there is an insufficient gas supply. To tackle such issues, contact our professional.

The Ductwork has Been Damaged.

Before reaching you, warm air will escape via small gaps and leaks in your ducting. Damaged ductwork is a big issue that causes your furnace to malfunction and blow cold air.

The Furnace had Become too Hot to Handle.

When a furnace overheats, it will start blowing cold air, seemingly counterintuitive. When a furnace becomes too hot, it shuts down to avoid a fire or further system damage. Even after the fan has stopped producing heat, it will circulate frigid air.
