Can I keep and resell my old working HVAC system?

Contractors typically expect to take and handle old units, leaving homeowners wondering if they can keep a functioning system to sell and recoup some of their replacement costs. Because used HVAC units have decent potential value, keeping them avoids unnecessary waste, though it requires having the storage space and navigating whether to ask the installer to leave it behind.
