Who hires for this

Builders and GCs post new construction and fit-out HVAC. Property managers post replacements and service, and larger HVAC contractors sub out ductwork and installs during their busy season.

What they ask for

• EPA Section 608 certification for anyone handling refrigerant
• State or local HVAC or mechanical license where required
• Certificate of insurance and workers comp
• NATE certification, which many GCs like to see
• Experience with the equipment brands on the job
• Start-up and commissioning paperwork

How to land more of it

• Say whether you fabricate your own duct or only hang it. GCs split those scopes sometimes.
• Heat pump experience is in demand. Show the systems you have installed.
• HVAC contractors sub out installs in peak season. Get on their list before it starts.
• Clean start-up sheets and warranty registrations make you easy to hire again.

What certifications does an HVAC sub need?

Anyone who handles refrigerant needs EPA Section 608 certification. Licensing for HVAC contractors varies by state, and some towns add their own. NATE certification is voluntary but shows up in a lot of GC requirements.

Who handles the electrical for HVAC equipment?

Usually an electrician runs the circuit and disconnect, and the HVAC sub does the low voltage controls and equipment wiring. Some states let HVAC licensees do more. Make the split clear in the contract.

Can I sub for other HVAC companies?

Yes, and it is common. Larger contractors bring in install crews when they have more work than people, especially in the heating and cooling rush. Be clear on whose name goes on the permit and warranty.
