<human>: So I had a new HVAC system installed in my house yesterday and before the installation one of the service techs was going over the different types of systems I could purchase to replace my old system. During this time he also mentioned that the company offered financing through Wells-Fargo. I didn't think anything of it because I had plenty of money in my emergency fund to cover it plus Wells-Fargo and the HVAC repair company are very reputable. However, the salesman later mentioned that the loan was interest free and I was shocked. I agreed to have the 24 month interest free financing instead of paying it off upfront thinking that since the loan was interest free there was no harm in having it financed so I could keep my emergency money in the bank. Well later on today I started to get a bad feeling about the whole deal. I found this [explanation of interest free financing] and understand now that I have a credit card through wells fargo with the balance of the HVAC unit loaded on. Now of course I am responsible with my credit cards and I keep them paid off so I dont think I will fall into a credit trap here but I still kind of feel uneasy about the whole situation. Do you guys think this was a bad move? What would happen if I just went and paid off the credit card early?

Can you provide a brief overview of the text?
