Learning About Furnace Upgrades and Repairs

Hello, my name is Sarah Patricks. I am going to use my site to talk about furnace options and repairs. There are a wide number of furnaces to choose for your home. The furnaces may kick on using natural gas, electricity, or oil for fuel. If internal components in the furnace stop working, the entire unit will fail to turn on during the next cycle. As a result, the temperatures in your home will drop dramatically, especially at night. I will talk about ways HVAC contractors keep furnaces in working condition. I hope you will use the information on my site to keep your furnace running. Thanks.

How To Deal With A Furnace Creating Cold Air

16 December 2020
 Categories: , Blog

Have you fired up your furnace and noticed that the air coming out is not as warm as it could be? You're likely wondering if there is anything you can do on your own to save yourself from making a service call, or if it is a problem that requires professional help. Here are some tips to help you deal with this issue.

Determine The Actual Problem

The first thing you want to do is determine the actual problem. Does it feel as if the furnace is blowing cold air, or is your house actually warm? If the home is comfortable but your air feels cooler than you think it should be, there may not actually be a problem at all. Take a temperature reading of the air coming out of the vents and see if it is normal throughout all the vents in your home. Isolated vents with cold air could be due to an air duct leak that is limiting air flow, and would require professional help to fix. 

Reset The Furnace

It's worth performing a hard reset of your furnace to see if that fixes an issue where it is blowing cold air throughout all the vents of your home. This will help rule out a problem with the pilot not lighting and causing the furnace to just run the blower. Shut down the power for about a minute, then turn it back on and see what happens. The normal sequence is that you'll hear the ignition start up, then the fan will eventually come on. Sometimes this is enough for the problem to fix itself, such as from a burner that had a pressure problem and went out. 

Check The Fan Settings

If the furnace seems like it is intermittently making cold air, check your thermostat's fan settings and see what they are set to. When turned on, the fan will run when the furnace is turned off, which helps circulate the air in the home. When turned to auto, the fan will only run when the furnace is running. Putting the fan on auto mode will prevent it from running at all times, which is creating that cooler air you are feeling.

Call A Professional

If you restart the furnace and just the blower came back on, this is an indication that something could be wrong with the ignition itself. This is a problem that is much harder to fix on your own and will best be handled by a professional. They'll be able to swap out the damaged parts with new ones, clean parts that are dirty, and get the furnace up and running again. Contact a residential heating service for more information.
