Commercial range in house: they don't have heat insulation, doors get hot, sides and back need distance from combustible surfaces (like cabinets), some need 3/4" gas piping, burners don't do very low simmer, hard to find a repairman who will service them in a home. They are far cheaper than the high end commercial-like residential ranges, like $2K vs $5-7K. That said, I know people with commercial ranges in their homes. As mentioned, I ended up with a $5K commercial-like residential range that is pretty close to an actual commercial range, but with heat insulation and one simmer burner, five big burners.

Commercial refrigerators in homes: noisy, not energy efficient, usually no freezer (there are dual temp models), no conveniences like door shelves, baskets, etc, don't fit the standard cut outs for residential refrigerators. I have a freezer in the basement and don't mind going there for ice cream, and I don't care about noise in my kitchen since there is always activity going on there anyway. Also way cheaper than the high end Liebherr, SubZero, etc.
