Ohio Requires Safety Locking Caps on all AC Units

Ohio Safety Cap AC

Why Are Safety Locking Caps Required in Ohio?

Locking caps are a safety feature on your AC unit that protects against substance abuse. Some states or building inspectors do not require locking caps on refrigerant lines, but in Ohio, it is required by law to have them. Homeowners should have locking caps installed on their air conditioning units as it is enforced very heavily by local inspectors during new installations.

The International Mechanical Code (section 1101.10) and the International Residential Code (section M1411.6) are now requiring the use of locking caps. Section M1411.6 says, "Locking access port caps. Refrigerant circuit access ports located outdoors shall be fitted with locking-type tamper-resistant caps." These caps are lockable and can only be accessed by a licensed HVAC professional who is equipped with a special tool. The caps may be color coded to allow for easy recognition of certain refrigerant lines.


Why do both the International Mechanical Code and the International Residential Code require locking valve caps on all outdoor refrigerant access ports? 

To limit access to the refrigerant to professionals servicing refrigeration systems in order to prevent the intentional inhaling of refrigerant.
