As a homeowner, you can troubleshoot a heater that still turns on but blows cold air. This problem could have an easy fix, but it could also require a professional technician to make a repair. Here’s a quick guide to why your heater might be blowing cold air.

DIRTY AIR FILTER

Dirt buildup on a filter can block warm air from flowing into your home. It’s important to replace the filter every three months. Not only is the air blocked from flowing out, but the dirty filter can also cause the equipment to overheat. Parts and components can break down faster, and the unit could become permanently damaged. Replacing the filter on schedule is a simple yet important task.

WRONG THERMOSTAT SETTING

If your thermostat has been set incorrectly or not adjusted properly for winter weather, your equipment can blow cold air. You may find that the fan has been inadvertently set to the on position. In that case, it will operate constantly, and the air it blows out won’t have been warmed. Consequently, it will feel colder than expected. When a heater is set to auto, it will cycle on and off according to the temperature requested. Reset your system to auto, choose the temperature you prefer and allow the equipment to respond.

PILOT LIGHT IS OUT

The small flame of your pilot light is the ignition source for your burner. Without it, the burner won’t ignite. When the pilot light goes out, the air your heater blows will feel cold. If you know how to relight the system, you can easily correct this. If you don’t or you have other concerns, contact a licensed technician for help.
