Your furnace helps warm your house, mainly during the cold season. Unfortunately, it might be one of the appliances you probably hardly think about. A furnace should be well maintained for it to work optimally. However, it can sometimes fail in the middle of the cold season. When this happens, you should hire a furnace repair technician to fix the problem. Handling a faulty furnace is not a good idea because you could compromise your safety or damage it further. Consider a furnace repair service when you notice any of these three signs.

A Yellow Pilot Light

You should always check the pilot light because it helps you know when all is not well with your furnace. The pilot light of a well-maintained furnace is blue. However, the color could change when the furnace develops a problem. It's, therefore, crucial to inspect its pilot light quite often. It's not usually a hard task because you just need to remove the cover panel to inspect it. The pilot light can sometimes be out for various reasons. If yours is out, just relight it and follow the instructions in the manufacturer's manual. Contact a technician if the pilot light is yellow because it shows the heat exchangers of your furnace could be leaking carbon monoxide.

Hiked Energy Bills

Various factors can contribute to hiked energy bills. However, some people don't know that a faulty furnace might be a culprit. Your furnace won't heat your home efficiently if it's old. Surprisingly, even a newer model could also lead to increased energy bills when defective. It usually works harder to warm the house, consuming more energy than it should. As a result, you experience hiked energy bills. Luckily, you won't experience this problem once you hire a technician to repair the furnace.

Strange Sounds

Most furnaces are usually designed to operate quietly or smoothly. So you should be worried when yours makes disruptive noises because they indicate something is wrong. The noise your furnace makes can tell the specific problem it has developed. Actually, most competent technicians diagnose the problem the furnace has developed based on the sound it makes. A furnace with loose internal components will make a banging sound. It may also make a rattling noise if its screws are loose. Furthermore, the furnace may make a whistling sound if its belt or fan is broken or damaged. So don't take the furnace's strange sound for granted. Instead, contact a technician to identify the actual cause and fix it.
