Signs That Indicate Trouble With Your Natural Gas Furnace

As a homeowner with a natural gas furnace in the home, you are going to want to be fully aware of the things that indicate trouble with it. This way, you will know when to call in a professional HVAC contractor. To help you with this, you can easily review the following signs of natural gas furnace trouble.

Explosion Sounds

Okay, so your furnace might not have actually exploded, but if you find that is occasionally sounds like it is, then you have a problem. This sound is generally the result of a buildup of natural gas that is sitting there getting bigger and bigger, until it finally reaches the pilot light that might not be as high as it should be. The pilot light may have simply been turned down by accident. Then again, there could be a buildup of dirt, debris, or minerals that is causing the pilot light to no longer burn as high as it once did. If the pilot light needs cleaning or you are still unsure as to what is causing the explosive sounds, you will want to turn off the furnace and call in a skilled HVAC contractor.

Banging Metal Sounds

Do you find yourself hearing a lot of sounds of metal being banged around? This could be the result of a broken belt, a faulty blower fan, or a motor that is starting to lock up. Either way, you might notice that this sound is going to get a lot worse before it gets better. Also, it will continue to get worse until you do something about it, such as calling in a reputable HVAC contractor to fix the problem for you.

The Flame Is The Wrong Color

It is important to make sure that you are occasionally checking the color of your natural gas pilot light flame. If it is burning yellow or orange, then it is time to turn off the furnace and call in an emergency HVAC contractor. Your pilot light should always burn as a crisp blue color. Anything else indicates a serious problem. No matter what is causing it, the different color tells you that your natural gas furnace is leaking carbon monoxide into the home, which is an odorless and very deadly gas.

With just those three signs in mind, you should feel much more comfortable knowing that you will be able to spot the need for an HVAC contractor as soon as possible.
