JOB OVERVIEW

I am building a professional HVAC design firm and looking for the right people to join early. I learned HVAC in the U.S. Military, worked as a technician for multiple companies, and later owned my own HVAC company for 12 years before selling it. Now I am shifting my focus completely into system design and estimating, and I want to build a strong and reliable team around that.

This position is not for someone who is trying to learn HVAC design. I need someone who already knows more than I do in the design aspect of the industry. I need a highly motivated, well educated, and reliable professional who can work confidently and independently, and who can teach me deeper design details over time.

There is limited room for error. We want well planned, safe, and high performing duct systems that are engineered correctly the first time.

What you need to bring

• Expert level ability with Manual J, Manual D, and Manual S
• Full Wrightsoft or equivalent design capability
• Accurate load calculations, duct layouts, airflow balancing, and system design documentation
• Ability to support estimating including takeoffs, BOMs, and equipment lists
• A strong understanding of selecting proper equipment for each application and the ability to make the best recommendation, not just a recommendation

Real world HVAC experience matters

You should understand:
• Airflow and static pressure fundamentals
• Spray foam and ICF envelope considerations
• Humidity control and proper moisture removal
• Designing for the coldest and hottest days of the year
• Long term comfort, safety, and indoor air quality
• How to prevent condensation and biological growth through proper design

Communication expectations

Perfect English is not required. I simply need the language barrier to be limited so that we can communicate clearly and avoid misunderstandings when discussing project requirements.

Work structure

• Project based work as needed
• Independent work without micromanagement
• Long term potential for a full time senior role for the right tea ---------- mber

How to apply

Please include:

• A short summary of your HVAC design experience
• Examples or screenshots of past projects (redaction is fine)
• Typical turnaround time per system or project
• Preferred rate (per job, per system, or hourly)
