The height requirement for refrigerant piping applies unless the piping is located against the ceiling.

The height requirement for refrigerant piping applies unless the piping is located against the ceiling.

• A. True
• B. False
• C. Not Applicable
• D. Sometimes

Answer: (A)

Height clearances for refrigerant piping are about keeping the line out of the way and making it accessible for service while protecting it from damage. In general, there’s a minimum height above the floor for these pipes. The statement is true because there’s an exception: when the piping is run against the ceiling, the usual floor-height requirement doesn’t apply. In that ceiling location, the pipe is out of reach and not in the path of people or foot traffic, so enforcing the floor-based height rule isn’t necessary.
