My gas furnace still runs, but it makes a lot of noise

My gas furnace still runs, but my gas furnace is also making a lot of noise.

I have no idea what is wrong with my gas furnace.

I thought that my gas furnace was in good condition, but when I bought this house, the gas furnace was pretty old. I called an Heating and A/C specialist, and I totally expected the Heating and A/C specialist to tell me that I was going to have to upgrade the gas furnace before the people I was with and I moved in. However, the Heating and A/C specialist told me that the gas furnace was in pretty good shape, and she expected the gas furnace to last a few more years. It has been a few years, and the gas furnace was working well. I was really bragging to all of my friends about how awesome this gas furnace was. However, the gas furnace is starting to act up, and I have no idea why; One afternoon, while the people I was with and I were getting ready for bed, the people I was with and I began to hear this certainly loud screeching noise. The two of us don’t have children or pets, so I had no idea what this screeching noise was coming from. While I was looking around for the source of the loud noise, I discovered that it was really coming from the gas furnace, and for some reason, the gas furnace was making this awful noise. I tried turning the gas furnace off and back on again, but it didn’t stop the screeching sound. I even called a single of my friends that have maintained Heating and A/C units before, and she confirmed that it was easily a pretty immense issue. However, just as the gas furnace randomly started screeching, the gas furnace stopped. Now, the gas furnace only does that randomly, but I think that it is getting more common. I am absolutely going to have to do something about my gas furnace.
