My Heater Is Only Blowing Cold Air!


The nights are cold in Yorktown, Virginia, and you want your heater to be in top condition. If you turn on your furnace and only feel cold air blowing, you may have problems with your thermostat, ductwork or the ignition system. Read on to discover solutions to these problems.

Check the Thermostat’s Batteries

If the fan setting is set to “on," the furnace will constantly blow air, even if the HVAC system isn’t actively heating. Set the fan to “auto” and you should feel warm air. Many thermostats use batteries. If the batteries are dead, the thermostat won’t function. Try replacing the batteries.

Investigate Leaky Ductwork

Your furnace creates warm air that gets transported into your home via ductwork. If the ductwork has leaks, warm air can escape before it gets delivered to your living spaces. In addition, if your ductwork clogs with dirt and dust, it can restrict airflow through the ducts.

Dirty ductwork also leads to poor indoor air quality, which is harmful to your family’s health. Therefore, it’s important to invest in duct cleaning.

Diagnose Ignition System Issues

Your furnace needs the pilot light to create warm air. If the pilot light has gone out, you’ll only receive cold air. If you’ve tried to relight the pilot light and it won’t stay on, you could be experiencing an issue with the thermocouple, which you may need to adjust or replace.

Always call a member of our service team if you can’t relight the pilot light or if you believe you’re facing a problem with the furnace’s ignition system. We’ll inspect and repair any problems your furnace may have so that your family can stay warm throughout the winter.
