Breaking up with contractor

[Heath D Wallace]

I am ready to just pay off my current contractor and hire someone else or just finish it myself. My current contractor started back in January 2025. Inside the property is nearly complete. The last major job is the HVAC install. I have a HVAC installer coming to give me an estimate for a complete install, Condenser, Furnace, A-coil, ducting, fuse box. If he can give me a reasonable price I will be looking to pay my contractor for the work he has done so far, and finishing up the rest. I believe 9 months is too long for a BRRRR.

Has anyone else been through this?  What kind of problems can I run into?
