4 Sounds that mean bad news from your furnace are BOOM, SCREECH, RATTLING, and CLANKING. If you're hearing bumps in the night.. no need to hide under the covers. The culprit very well may be your furnace. Most definitely any out of the ordinary sounds coming from your heating and air system can pose a big problem. Immediate action is required. 
Recently, we had a Calhoun heating repair visit where the sounds coming from the furnace sounded as if we were in a machine factory. Thankfully the customer called right away to address the issue, but had they not, it could have been a huge hit to their wallets! As expected, the customer was alarmed and thankful to have the peace and quiet of her home once we repaired the system.
B is for BOOM!
Are you hearing a boom or banging noise coming from your furnace? It could mean something as simple as a dirty burner. This most certainly is not a sound to ignore. Any possible repairs involving your burners, if neglected, can become dangerous. We always want to stress that anything involving the burners and possible gas emission, should be addressed sooner than later.
If you are hearing a boom sound coming from your furnace, the combustion chamber and burners can become clogged from grime and build up. The gas builds up and when it ignites, makes a "boom" sound. Dirty heating equipment can cause a problem called "delayed ignition" where there is a small explosion within the combustion chamber.
Preventative heating maintenance is the way to prevent the furnace sound of "tick tick BOOM." Get that heater repaired and continue with routine inspection and cleanings. This will assure your heater is operating safely, which is most important.
Cover Your Ears… SCREEEEECH!
That grinding and screeching you are hearing from your heater is most certainly not good. Your furnace has a number of electrical and mechanical components. When these components stop working , yet your system is still running, it can cause a screeching sound. Usually the culprit is your blower motor, which is what pushes the air throughout your home. While the screeching blower motor may just need some lubrication, it could also be "seized up."
A screeching furnace sound is a good indicator that your heat is not blowing or will need emergency heater repair soon enough. We can't stress enough that routine check ups will help prevent these unbearable furnace sounds.
