Position Overview

We are seeking a highly capable Commercial HVAC Sales Engineer / Account Executive to lead tenant improvement (TI) and special project opportunities within our commercial portfolio. This role is ideal for a technically strong professional with an engineering background who can independently develop HVAC concepts, prepare drawings, estimate projects, and guide customers from initial design through project completion.
This is a hands-on, technically driven sales role focused on fast-paced TI work, retrofit projects, and smaller-to-mid-sized special projects, rather than large ground-up construction.

Primary Responsibilities

  • Develop and grow tenant improvement and special project opportunities with existing and new commercial clients
  • Serve as the technical and sales lead for TI projects from concept through close-out
  • Independently develop HVAC system layouts, concepts, and solutions

  • Estimate, propose, sell, and manage awarded projects
  • Act as the primary point of contact for customers throughout the project lifecycle

Sales, Engineering & Estimating

  • Meet with building owners, property managers, general contractors, and tenants
  • Perform job site walks, field measurements, and as-built verification
  • Develop HVAC system designs and layouts for tenant improvements
  • Prepare HVAC drawings and markups using AutoCAD, Bluebeam, or similar tools
  • Define project scope, equipment selections, and system approach
  • Create accurate project estimates using Excel-based tools
  • Prepare customer proposals and presentations

Project Management (Post-Sale)

  • Coordinate manpower requirements with operations
  • Assist with permit and plan submittal requirements
  • Prepare and distribute submittal packages

    Coordinate with general contractors, subcontractors, and vendors
  • Purchase equipment and materials
  • Manage project documentation and close-out requirements

Qualifications & Experience

  • Engineering background (Mechanical Engineering preferred)
  • 3+ years of experience in commercial HVAC TI, retrofit, or special projects
  • Strong working knowledge of commercial HVAC systems
  • Ability to prepare HVAC plans and drawings independently
  • Experience in design-build or technical sales environments

Technical Skills

  • Microsoft Windows and Microsoft Office (Word, Excel)
  • AutoCAD and/or Bluebeam (required)
  • Ability to read and create construction documents
  • HVAC load calculations and basic system design knowledge
  • Revit experience is a plus

What We Offer

  • Competitive base salary plus performance-based incentives
  • Company vehicle or vehicle allowance (if applicable)
  • Health, dental, and vision insurance
  • Retirement plan options
  • Paid time off and holidays
  • Long-term growth opportunities
