As winter temperatures decades, it’s important to have a reliable furnace to keep you and your family comfortable in the harshest of weather. The last thing any homeowner wants is to discover cold air coming from their air ducts. However, if you’ve come across this problem, your local HVAC technicians at True North are here to help 24 hours a day, 7 days a week. Keep reading our blog to discover the most common causes of cold air blowing out your furnace and what you can do to make sure it never happens again.
Wrong Thermostat Settings
It’s always important to start with the easiest possible answer to your furnace problem. Have you double checked your furnace settings? If that answer is no, or you’re rolling your eyes at such a simple reminder, trust us – it’s something homeowners overlook all the time. If your fan is set to “on”, no matter what your thermostat is set too, cold air is going to come from your vents. If you notice that your furnace sometimes blows warm air and other times it’s cool, this is likely a fan setting issue on your thermostat that requires an easy fix from our team. If your thermostat is older, it could be touchy and set certain settings without even having to touch them purposefully. To be sure, schedule a maintenance check with one of our heating experts at True North in Newark, OH.
Dirty air filters are one of the most common causes of heating issues with gas and electric furnaces. Many air filters are meant to be changed once every 1-3 months depending on the size and type of furnace you have; unfortunately, many homeowners have busy lives and end up waiting until a year or longer to check their air filters. If you notice cool or slightly warm air coming from your airducts, and you’ve doubled checked the thermostat, the next likely issue is a clogged air filter. True North offers affordable maintenance services for systems needing a replacement filter, along with a comprehensive cleaning and inspection of your heating system. Once your air filter is replaced, you should notice a major difference in the heat produced by your furnace.
Pilot Light or Igniter Issues
Gas furnaces have a pilot light or igniter that is used to spark natural gas and turn it into a steady flame that produces heat for your home. When your pilot light has gone out or the igniter is damaged, you’ll notice right away that there is an issue when cool air flows from your vents. An extinguished pilot light can be relit; however, a bad igniter will need to be replaced by a certified HVAC technician. At True North, we offer complete furnace repair and replacement services for homes and businesses in Newark, OH. Many safety features in your furnace will shut down the entire system to prevent gas from invading your home. If you feel a cold and steady stream of air coming from your vent, followed by an abrupt stop, call our team right away for an inspection.
Dirty Flame Sensor
If you own an electric furnace, your system will have flame sensors, otherwise known as flame rods. These parts allow for proper heat to flow from your system, into your vents, and throughout your home. When your flame sensor is covered in years’ worth of dirt and grime, you’ll notice cool air coming from your furnace with each cycle. Thankfully, this is a simple maintenance fix and can be done by homeowners that are familiar with the internal system.
