A furnace is an essential part of your house especially around winter time. It keeps the household warm and free from cold. However if you noticed a sudden spike in your bills or noticed that the furnace cycles goes on and off more than it’s supposed to work then you may have problems with it. In order to check out what is wrong with your furnace, here are the things that you should take note of.

What to check in your furnace:

Check for any odd smell coming from your furnace

You know your furnace is broken when you can smell an unusual odor. This is a definitive sign that there something that needs to be fixed in your furnace as they don’t really emit any kind of smell in the first place. Sure, the furnace may emit an odor after an hour or two once it has started but that is most likely due to the dirt it has accumulated. However if the smell lasts for hours, it could be due to a clogged filter or dry heating. The ventilation and air conditioning ducts may also be clogged.

If the furnace’s burners are dirty then expect odor coming from it. An overheated furnace system can also cause the smell. In case you smell gas coming from your furnace it could be due to leaky or cracked ducts and pipes. Make sure to leave your home until it is fixed.

There is sound coming from your furnace

Besides the smell, furnaces that are making sound for a period of time usually tell you that there is a problem. Normally, a furnace may cause a few ticks and rattles once it is activated but if the sound is crackling, sizzling, squealing and the likes, it may be due to parts that needs lubrication or motor belts that needs fixing. If the furnace continues to create grinding sounds, or constant clicking, your furnace might not be functioning properly. It’s best to have it checked right away if you don’t want any further damage to your furnace.

Check how your furnace looks

When a furnace is broken you can easily see if by just looking. If it is covered with dirt and dust then you may have a real problem. Rusts, cracks, burn marks and the likes are also among the things that you need to check in your furnace. Dirty burners may cause yellow and blue flames. If this happens, it’s time to clean out your furnace and check what other problems it might have.

Check if the filters are clean

A clogged filter may cause odor to your vents. If the filters are not regularly cleaned, it may cause other problems in the long run. If this is the case then all you need to do is get rid of the old filter and replace it with a new one.

There’s a rise and fall on the temperature

If you noticed a sudden change in the room temperature several times a day, it could be because of a broken furnace. To check if your suspicions are correct, place a thermometer in a room and take down of the temperature. Compare the readings to the recommended temps and see if it’s within normal range. If it is below or higher than the normal range then you definitely have trouble with your furnace.

In case you find any of these upon inspection, it’s important to have it checked right away. Immediate repairs on your furnace can prevent further damage than it already has. So make sure to give it a regular checkup at least once a week. It will help save you money in the future!
