Do HVAC technicians need to be registered or licensed?
I see 2 different trains of thought on this, if I was called to do an emergency repair that is a call that can be charged for even if the unit was not repairable. But if called for a quote on updating a system that would be different some do charge for quotes but take it off when they get the job, most don't charge for quotes. But it sounds like an emergency call was made so there could be a charge without a contract. But yes contractors need to be licensed and for hvac also need an EPA license called 608 1, 2 or 3 if they have all 3 it is called a universal license, but a 609 license is also required for motor vehicles to be able to do everything.
