Winter can be a tricky season for many homeowners. With low temperatures and the need to keep your home comfortable, it is important to make sure your furnace is running in peak condition. Unfortunately, furnaces are not designed to last forever, and at some point, you will likely have an issue that requires professional attention. To help you avoid costly repairs or even dangerous situations, here are four signs you should watch out for that indicate when it's time to call a furnace repair contractor.

1. Strange Smells

If running your furnace produces strange smells such as musty odors, burning rubber, or something else unpleasant then it could mean there is a problem with your unit. You may be able to pinpoint the source of the smell, such as a dirty air filter, but it's still important to have a professional take a look. If left unchecked, strange smells can indicate larger issues with your system and you don't want to risk further damage or endangering yourself and your family by running an inefficient furnace.

2. High Energy Bills

If you notice a significant increase in your energy bills then it could be time for some maintenance on your furnace. This is especially true if you haven't changed any of your habits such as taking longer showers or leaving more lights on throughout the house than usual. A faulty heating system may not be operating at its most efficient setting, resulting in higher energy costs for you each month.

3. Loud Noises

While furnaces do make a certain amount of noise when running, loud noises such as banging, rattling, or squealing can indicate a problem with your system. These could be caused by an old part that needs to be replaced or worn-out bearings that need lubrication. In any case, it is essential that you have this issue taken care of before using the furnace again.

4. Flickering Pilot Light

The pilot light in your furnace should always remain lit, and if it flickers on and off then there is likely something wrong with your system. This issue could range from something minor like a buildup of dust or dirt inside the unit to more serious issues such as a gas leak. Either way, it is important to contact a professional for repair as soon as possible since this could be a hazard in your home.

When the winter months hit, having a reliable furnace is essential to keeping yourself and your family warm and comfortable. If you notice any of the signs listed above, then it's time to call a furnace repair contractor before the issue becomes more severe or dangerous. Taking this precautionary step can help save you money in repairs and prevent potential hazards inside your home.
