Should I upgrade my gas furnace

Honestly, I am not sure if I should upgrade my gas furnace, however I am seriously considering it, i honestly do not love the gas furnace that I have.

I do not even suppose if the gas furnace is going to last a long time. It is just so strenuous to tell, then my gas furnace is broken, and it isn’t doing anything right now. I have been having a lot of issues with my gas furnace; Every year, I have some kind of major problem with my gas furnace. My gas furnace is honestly old, however for the last few years, the Heating and A/C specialist has been convinced that he can help me get a few more years out of the gas furnace, however, I am pretty sure that that is running short, however when I called the Heating and A/C specialist to schedule the inspection for my gas furnace, he came over abruptly. However, but I only have a single gas furnace in my house, it took the Heating and A/C specialist a honestly long time to inspect my gas furnace. When the Heating and A/C specialist found me, he told me that the gas furnace has some pretty major issues; Apparently, the gas furnace was going to cost way over a thoUSnd dollars to repair; Furthermore, since the gas furnace is so old, it will continue getting worse and worse; The Heating and A/C specialist told me that I could also consider buying a new gas furnace, however I am not sure. He said that it was my option as to what to do. I have no idea! Obviously, if I can save money by fixing my gas furnace, I would rather, however the Heating and A/C specialist no longer seems sure that my gas furnace will last honestly long. I do not want to dump all of this money into my gas furnace just to have to upgrade it next year.
