Why is My Furnace Blowing Cold Air?

A furnace that isn't blowing warm air clearly isn't doing it's job. If you're having this problem and trying to troubleshoot, here are some things that may be causing the issue:

  • No Fuel. Furnaces depend on fuel in order to run. When there is no fuel in your furnace and the furnace is turned on, it will only blow out cold air. If you have a gas furnace, check the pilot light. If you have an electric furnace, make sure that your electric breakers are in the on position.
  • Clogged Air Filters. If your furnace is blowing out cold air, a dirty air filter could be to blame. A clogged air filter will only inhibit airflow, which also leads to heat loss. Changing your air filters once a month or as needed is a must.
  • Broken Duct Work. Duct work takes the heat from your furnace and distributes it to the rooms in your home. However, if your duct work is damaged, it will be carrying cold air to each room. If you suspect that your duct work has holes in it, have it patched up by a professional.

Signs You Need a New Furnace

  • You’ve had your furnace for 20 years or more.
  • The flame on the burner is yellow instead of blue.
  • Your furnace has started to make noises; such as banging, popping or hissing.
  • Your gas and electric bills are on the rise.
  • You constantly change the temperature on the thermostat to stay warm

Things to Consider When Buying a New Furnace

Are your heating bills unreasonably high? Your old furnace is probably burning your money away. If that is the case, it might be time to purchase a new one. With so many choices on the market today, it can be hard to make a selection. Below are some key points that will help you narrow down the search for the perfect furnace.

Size Matters

When it comes to furnaces, size matters. If you have a large house and a small furnace, it will have a hard time warming your house effectively. It will end up using more electricity in order to make it to all areas of your home. In return, this drives up the cost of your utility bill. Only a properly sized air conditioning unit will effectively warm your home.

Energy Efficiency

A new furnace is bound to be more energy efficient than an older model. In fact, all new furnaces on the market today come with an Energy Label Guide. This is a helpful tool that displays the annual energy costs.

The Price Tag

As with any purchase or investment, it is important to have a realistic budget in mind. Investing a decent amount of money in a furnace could save you money on your utility bills in the long run.
