Craft Installs That Last

Build with Precision. Grow with Purpose.

At SumZero, installation isn’t just about hooking up equipment. It’s about protecting customer trust, representing the brand on-site, and training the next generation of professionals. We’re looking for HVAC Installers who take pride in their craft and believe that a great install is the beginning of a long relationship — not the end of a transaction.
If you want to be part of a team that’s known for quality, accountability, and mentoring — this is your shot.

What You’ll Do

  • Install new heating and air conditioning systems with precision and pride
  • Follow clear project plans and execute top-tier workmanship
  • Train and mentor apprentices during jobsite execution
  • Diagnose and resolve installation-related system issues on-site
  • Ensure compliance with all safety standards, code requirements, and protocols
  • Communicate clearly with customers and project managers
  • Keep your workspace clean, organized, and safe
  • Represent the company with professionalism at every stop
Hours: FullTime
Location: Holliston, MA
Start Date: As soon as you’re ready

What You'll Get

  • $35/hour starting pay, depending on experience
  • Company vehicle, gas card, uniforms, and tool reimbursement
  • Paid vacation, holidays, and health insurance
  • Simple IRA retirement contributions
  • Daily support and long-term opportunity
  • A company culture rooted in mentorship, excellence, and respect

“There’s no egos here. You do great work, they notice. You need help, someone shows up.”
Maurice D., Service Manager

What You Bring

  • 5+ years of HVAC install experience in residential systems
  • Ability to read and interpret system designs and project plans
  • Strong knowledge of air handlers, ducted/ductless systems, line sets, condensate management, and controls
  • Experience with boiler system tie-ins and water/air balancing is a plus
  • Valid driver's license and a clean driving record
  • Willingness to lead crews and support junior teammates
  • Pride in your work and accountability to your crew
