Imagine in the middle of winter, coming home after a long day at work or school and settling down with your family after to do homework, or watch a movie and suddenly there is cold air blowing out of your vents! This could be prime time to panic, but don’t! Here are a few things to check to troubleshoot before calling us to help.
Check your Thermostat
Make sure your thermostat is set on the correct setting. If it is set to “ON” the blower will run constantly even when the furnace isn’t heating any air. And the air that comes through the vents will seem cool because it is room temperature air. Turn your thermostat to “AUTO”, now the fan will only run when the furnace is heating and you won’t get tepid or room temperature air.
Change the Air Filter
A dirty air filter will cause your furnace to overheat. It restricts the air flow in and out of your furnace which can cause it to overheat. If it does overheat, the safety control will shut off the burners causing the fan to blow cool air versus heated air through the house.
Check the Pilot Light
Your furnace may be blowing cold air because the pilot light has gone out. It is a simple fix, just relight the pilot. If it continues to go out after you relight it a few times, then you should call us at 505-975-2550 or request service online. This is indicative of a bigger problem that requires professional help.
Reboot Your System
If you have a modern furnace, you probably have one that is controlled by a computer. Sometimes there is simply a glitch in the system and it needs a simple reset, the same way you would restart your computer or phone. If you turn off your furnace for 30 seconds and then back on, it may reset itself and begin functioning correctly. If it doesn’t start working the way it should after you have restarted the computer, call us or request service online today.
The older you ductwork is, the more likely it is to be damaged or leaky. If you have a damaged or leaky ductwork air can be escaping before it gets to the desired living areas. Inspect the ductwork yourself, but its possible that you may not be able to visually detect the rips or tears that are causing your leak. It is best to call us or request service online, for an in depth ductwork inspection.
