Lead Supervisor HVAC Journeyman

Advantage Air needs a licensed journeyman who can install a system in the morning and solve a no-heat call in the afternoon. You'll be the lead supervisor for a small field team, working directly with the owner while we grow.

About Advantage Air

Advantage Air has served St. Louis homeowners, apartment communities, and commercial customers since 1999. We're a locally owned Bryant dealer based in Valley Park, and we came under new local ownership in 2026. We keep the old-school service that built the company and are adding better tools and systems. Our goal is to grow the field team to 6–7 techs.

About the role

No two weeks look the same. You'll handle replacements, service calls, maintenance, and sheet metal on residential, multifamily, and light commercial jobs. A year from now, you'll be someone customers ask for by name and the tech newer team members come to with questions.

This is a small company still building its processes. You'll have real input and a respectful, no-drama place to work, but you'll also need to be comfortable when things aren't perfectly polished yet. Summer attics and on-call nights are part of the job.

What you'll do

• Install and replace furnaces, air conditioners, heat pumps, and related equipment from start-up to final walkthrough
• Diagnose and repair heating and cooling systems, including electrical and refrigerant problems
• Fabricate sheet metal in our shop and on site, including transitions, plenums, and duct changes, and install it
• Perform maintenance on residential, multifamily, and light commercial equipment
• Complete work to code and support permits and inspections
• Explain problems and options to customers in plain language
• Keep your truck stocked and organized, and record time and job notes in our field software
• Supervise and mentor the field technicians, and hold installs and service work to a high standard

Required

• Active St. Louis County journeyman mechanical license (HVAC Service-Installer), which you'll hold for the company as its license holder
• EPA 608 Universal certification
• 10 years of hands-on HVAC experience, including both installation and service
• Hands-on sheet metal fabrication experience
• Valid driver's license and clean driving record
• Ability to pass a background check and drug screen

Preferred

• City of St. Louis mechanical license
• NATE certification
• Experience with Bryant or Carrier equipment
• Experience with light commercial rooftop units

Pay and benefits

• License incentive for holding an active St. Louis County journeyman license, plus performance bonuses tied to daily revenue, service agreements, and system replacements
• Take-home company vehicle and fuel card
