A telltale sign that something is wrong with your home's furnace is if it makes a lot of noise when running. It shouldn't do this and if it is, you need to repair it before a major system or part breaks down completely. These repair tips can keep you away from trouble.

See if Part Tightening Does the Trick

When furnaces make noise, sometimes it's just because some of their parts have loosened over time. You might look into this potential cause first before taking your furnace apart and going through extensive repair steps to alleviate the noise. 

For instance, there might be some fasteners that just need to be tightened. Then components won't move around as much and make noise when the furnace runs. This repair step doesn't cost you anything and may be all that you need to do.

Lubricate Moving Parts

Another culprit of sound coming from the furnace is friction. There might be some parts that are rubbing against each other and thus causing this noise to develop each time you run the heating system. In that case, what you can do is lubricate these moving parts and thus reduce friction.

That should help you bring the noise levels back to a normal range. Make sure you use lubricants that are designed for your furnace's components and treat them at consistent intervals. Then chronic noise shouldn't continue unless something more serious is wrong with your furnace.

Opt For Professional Assistance When Loud Booms Occur

One of the more startling sounds a residential furnace can make is a boom. It kind of sounds like an explosion. If your furnace has reached this point, then you need to stop using this heating system and have it looked at by a repair contractor that specializes in furnaces.

Your burners are more than likely dirty and that's the reason why you heard the loud noise. Furnace repair contractors can easily clean these components and check other systems to verify your furnace is not a hazard to your family. That should take care of the noise and, more importantly, give your family peace of mind.

If you're having to deal with loud noises coming from the furnace when it's active, do something about these complications before you're left in a bad spot with part replacements and repairs. You just need to listen to this system when it runs and refine your inspections based on the noises you hear.
