Walla Walla’s freezing winters are brutal to bear, and not having a furnace working correctly can pose a huge problem. If your furnace is not blowing sizzling air, there might be quite a few reasons behind it. But, we’re here with all the solutions to help.

Read the article to know what’s causing your furnace to blow cold air instead of hot, and for solutions to fix it!

Incorrect Thermostat Settings:

Often, it’s the thermostat that stops your furnace from blowing hot air. Thermostat problems can be many, but there is a solution for all of them. When your furnace stops blowing hot air, then check the thermostat first. This might lead you to save money by not calling in the professionals.

  • If your thermostat is set to ‘ON’ all the time, it will blow cold air at some point. This is because a furnace does not blow hot air continuously, and when it reaches the desired temperature, it will blow cold air until the room cools down again.
  • According to their comforts, if the thermostat has been adjusted by someone else, then the chances are that cold air is blowing because they might’ve left the switch in the ‘ON’ position.
  • A low battery can also cause the furnace to misbehave. It can alter the furnace’s settings and cause it to blow cold air instead of hot. However, this is more likely to happen in old units.

The trouble with the condensate lines: 

Cold air can cause condensation in the condensate lines in the summer. This water can turn into slime if there is a lot of dirt in the pipes. This, in turn, stops the flow of the condensate lines and blocks the pipe. When winter approaches, this blocked condensate line causes trouble and stops the furnace blowing hot air. So, clean the condensate lines regularly to avoid this issue.

Dirty and clogged filter:

Another problem warrants an easy fix. If your furnace filter is dirty due to the accumulation of dust and dirt, it can stop the airflow to the furnace. This can lead the furnace to blow cold air. So, to fix this, you need to change your air filter regularly, once every 90 days or so.

Burner & flame sensor issues:

The furnace will stop producing hot air if either of these components is covered in dust and dirt. To fix the issue, consider cleaning these components. Switch on your furnace after that.

Leak in the ductwork:

Your ducts and pipelines may have been subjected to outerwear and tear, which can cause leaks. This allows outside air to mix with the hot air. To prevent this from happening, consider repairing your vents and ducts.

These issues are the most common ones when your furnace is not blowing hot air. However, the pilot light, high limit switch, or gas valves might also be at fault. However, pilot lights are present only in older furnaces, so if some work is done on the gas lines, it might lead to the pilot light going out. Also, systems with pilot lights should be replaced by newer models, as they’re more efficient and cost-effective.
