Planned Impact on the HVAC/R Industry
The USA is like a great big franchise. The states are the franchisees and the Federal Government is the franchisor. In return for their participation, the states (aka Franchisees) get to pick and choose from a menu of services. Some states take The Franchise exactly as it is, and some tweak things to accommodate their citizenry.
The US EPA (aka Franchisor) recently began to relax the requirements for the Franchisees. So many of them have begun to set their own policies in place. Specific legislation is in place in six states, and more than 30 states have some type of regulatory action that affects every HVAC/R owner, installer & servicer in the US.
