Does anybody know for certain if in the State of Georgia, an HVAC ("conditioned air") license is required in order for a homeowner to install their own HVAC system?

The type of unit called a "package unit", where the condenser and air-handler are combined into a single outdoor unit comes from the factory already charged.

That solves the refrigerant side of the equation. Don't actually know if that is sufficient in Georgia or not.

Some un-named individual who lives in my house in NC installed one of these and, so far at least, has gotten away with it.

Refrigerants are controlled by the EPA, so a license is required for charging the system in any state. However, the installation is not regulated.

  • There's also a bit of electrical work involved, which may or may not be homeowner friendly. – Tester101 Sep 21 '15 at 10:56
  • The low and medium voltage electrical is not trivial, by any means, but there isn't a law requiring a license by the homeowner to do it himself/herself. – N8sBug Sep 22 '15 at 0:40
  • There aren't rules against it where you live, or there aren't rules against it anywhere? – Tester101 Sep 22 '15 at 1:59

    GA requires a permit to do the work but a licence is not required if you are the homeowner. I have yet to run into a state that does, state websites are pretty clear about it. – N8sBug Sep 23 '15 at 9:16
  • This. You need a license to buy REPLACEMENT refrigerant. Once you own some, which new condensers come charged with and which do not require a license to purchase, and you use it for devices in your own home, then you just have to follow the rules. – Mazura Jul 2 at 4:17

You should contact your local building department. They'll be able to definitively answer your question.

Though I'd be surprised if a homeowner had all the tools and knowledge, required to install an air conditioning system themselves.
