Furnace Repair: 3 Strange Noises That Indicate Repairs Are Needed

If maintained and cared for properly, your average furnace can last you anywhere from 15 to 20 years. To avoid costly repairs or having to replace the furnace prematurely due to damages that have worsened over long periods of time thanks to being neglected, you should clean and inspect your furnace each and every year. During normal operations, a regular furnace will usually make a low, rumbling noise. This type of noise is not a cause for concern; however, if you start to notice your furnace singing a different tune and making other weird sounds and noises, it's usually indicative that something is malfunctioning and needs to be repaired or looked at by a licensed technician immediately.
