HVAC License vs. Electrical License Guidelines

As of April 1, 2015, the following guidelines apply for the installation of new and/or replacement of HVAC systems:

• All new units require an electrical license, NOT HVAC license.

If there is a proposed REPLACEMENT, the following guidelines apply:

• The unit must be less than 25 tons.
• Max 240 volt SINGLE PHASE.
• The contractor may only run wire from the existing disconnect to the new/replacement unit.
• All low-voltage applicable wiring.

If the proposed replacement does not comply with the above listed criteria, then a licensed electrician must be used.
