You can get pro sounding recordings with a $100 preamp and a $79 microphone, so equipment is not your problem. The use of it is.
If your hearing something in your recording, you need to find the source of it. No one here can tell you. We can guess. Maybe its street noise or your A/C unit or maybe its your PC noise. Maybe a bad cable or mic. It can be anything and everything. Even Jewelry that you are wearing.
