Why won't supply houses sell to homeowners?
Specialized industrial supply houses refuse to sell parts and materials directly to homeowners, forcing them to hire licensed contractors for simple DIY repairs. This restriction locks everyday buyers out of affordable retail pricing on items like capacitors and motors, driving up project costs tenfold through mandatory service fees.
