Cold Air

Why is Cold Air Coming Out of My HVAC System’s Air Vents?

November 24, 2020

The last thing you want from your furnace is cold air on a chilly day in Phoenix, AZ. What follows are some explanations why cold air is coming out of your air vents.

The Flame Sensor is Dirty

Without a flame sensor, your gas furnace has no idea how to power on or distribute warm air. If the sensor’s dirty, there’s no way to recognize signals that show the burners are on. This could be the result of cold air pushing through the system.

The Pilot Light is Faulty

Older furnaces use pilot lights and they can go out. Consult instructions in the manual or on the unit itself to safely relight the pilot. If the pilot keeps going out, you need to call a service technician for a closer look.

Condensate Clogging

Newer furnaces with a high-efficiency rating use condensate drain lines. The drains remove moisture created throughout the heating process. If your lines clog, a switch may activate that prevents burners from lighting.

Lack of Gas Supply

If there’s cold air, check and ensure your gas supply isn’t shut off. Another issue could be the gas line is faulty and not sending enough gas to the furnace. Either of these can make the furnace shut down for safety purposes.

Check the Heat Pump

If you’re using a heat pump, there could be a malfunction in the unit. The problem could be low refrigerant, bad valves or a glitch in the metering device. Correcting these issues definitely requires the expertise of a professional.

Don’t poke in your furnace hoping to fix things and risk causing more damage. Though common, these issues contribute to system instability. If not dealt with promptly and properly, small issues turn into big problems.

The smart move to confronting heating problems is to bring in a service technician. They’re trained to save you money and time while keeping your home comfortable year-round. Call REEis Air Conditioning to get your furnace back in shape pronto!
