Why is My Furnace Blowing Cold Air?

At this time of year in the Northwest, our furnaces are some of our closest friends. The last thing you want to have is a furnace that malfunctions – brrrr! But don’t panic. While it might seem alarming that your furnace is blowing cold air, there are a few common reasons why.

#1: The furnace isn’t fully warmed up.
When you first turn on the furnace, it’s common for it to blow a blast of cool air. It often takes a few minutes for the air to feel warm. That’s because the cooler air needs to come through the vents. Give the furnace some time to warm up. Think of it kind of like letting your faucet water warm up – you’ll get cold water at first, then it will gradually get warmer. If the furnace isn’t blowing warm air within a few minutes, there is likely something else going on and a service call to our team at Specialty Heating and Cooling may be in order.

#2: Your thermostat may be on the wrong setting.
Is the air from your furnace constantly cool? Check your thermostat to make sure that the fan is set to ‘auto.’ If it’s set to ‘on’ only, then it will run even when the furnace isn’t heating the air. Keeping it on ‘auto’ will ensure that the fan only runs when the furnace is heating the air and bringing that air inside.

#3: Your filter is clogged.
When was the last time you changed or cleaned your air filter? Dirty air filters create problems for your furnace. It restricts your airflow causing your furnace to run longer, using more energy. If this goes on for a long time, the furnace can overheat, and this brings only cold air in. We recommend replacing or cleaning your air filter on a consistent basis for the type of filter and the use within the home  This helps your system work more efficiently and prolongs the life of the system.

Are you still having problems after troubleshooting? There may be something more serious going on liked a broken circuit board, a faulty igniter, or something else.

Signs Your Furnace Needs Fixing

When the temperature drops, you need a furnace that’s reliable and ready to keep you warm and comfortable. But as with any machine, time and usage can cause wear and tear. That means your furnace may need repair. How do you know that it needs fixing? Here are some common signs.

#1: Weird odors or sounds.
Your heating system should never have any loud noises or odd odors coming from it. Don’t ignore any smells – especially a rotten egg odor or a smoke or burning scent. This could signal something dangerous. If you hear something banging or clanging, it could mean that there is something loose or broken inside. Screeching noises could indicate a belt issue.  Even if the sound or smell doesn’t happen all the time, it should be looked at immediately. Prolonging a repair can increase energy usage or put extra strain on the machine, which can cause even more damage to other parts of it.

#2: A spike in energy bill.
Did your last energy bill make your eyes go wide? Maybe the cost went up so much, you thought there was a mistake. If utility costs weren’t raised, but your bill increased a lot, you may have a problem with furnace efficiency. Our team at Specialty Heating and Cooling can look and determine what the issue is. Preventative maintenance appointments are one way to do that. We will diagnose the problem and get it fixed and make sure the system is running at peak efficiency before we leave. If you notice a spike in your utility costs, let us help get everything repaired and running well again so you can save money and reduce energy usage.
