We are seeking an experienced Commercial HVAC Design-Build Sales Representative to develop and sell commercial HVAC solutions from initial concept through project handoff.
This is not an entry-level HVAC sales position. You will work directly with contractors, building owners, and other project stakeholders to understand their needs, evaluate project requirements, develop HVAC systems, prepare estimates, and turn opportunities into profitable projects.
The right candidate understands commercial HVAC systems and is comfortable combining technical knowledge with relationship-driven sales.
What You'll Do- Build relationships with general contractors, building owners, and commercial customers
- Identify and pursue new design-build HVAC opportunities
- Meet with contractors and customers to evaluate project needs
- Review drawings, specifications, building requirements, and project scopes
- Develop HVAC system concepts and project solutions
- Prepare estimates, proposals, and pricing for commercial projects
- Coordinate equipment, material, labor, and subcontractor pricing
- Present solutions and proposals to customers
- Negotiate project scope and pricing
- Work with project management and operations teams during project turnover
- Maintain an active pipeline of commercial opportunities
- 2 or more years of commercial HVAC sales, estimating, design-build, or related experience
- Strong working knowledge of commercial HVAC systems
- Experience reading construction drawings, plans, and specifications
- Ability to develop estimates and project proposals
- Strong customer-facing and relationship-building skills
- Ability to manage multiple opportunities and projects simultaneously
- Valid driver's license with an insurable driving record
- Ability to work in-office daily and travel locally as needed
Relevant industry experience is more important to us than specific certifications. We are looking for someone who understands commercial HVAC projects and can confidently work with contractors and customers.
If you have the technical knowledge to understand a commercial HVAC project and the sales ability to turn that opportunity into business, we want to hear from you.
Join Crystal Heating and Cooling and help us continue growing our commercial design-build business.
