Job description

Comfort Systems of Montana

Lead Retrofit Installer

Bozeman, Montana

Job Summary

Comfort Systems of Montana is looking for a skilled, experienced Lead Retrofit Installer who takes real pride in their craft and wants to be part of a team that refuses to settle for average. This is a hands‑on role built for someone who lives and breathes HVAC, knows residential systems inside and out, and can walk into any home and own the job from start to finish.

You will be working on the equipment that matters most to homeowners every single day: furnaces, air conditioners, heat pumps, ductless mini‑splits, hot water tanks, and everything that keeps a home comfortable year‑round in Southwest Montana. You will set the tone for the crew, deliver installs that reflect the Comfort Systems of Montana standard, and bring the kind of experience, ownership, and craftsmanship that makes every job a win for the customer and the team.

If you are the type who holds a high standard, gets it done right the first time, and wants to grow with a company that actually invests in its people, this is the role for you.

Key Responsibilities

Residential Retrofit Installations:

• Lead and complete full residential retrofit HVAC installations including furnaces, air conditioners, heat pumps, ductless mini‑split systems, hot water tanks, and related comfort equipment.
• Perform complete system changeouts: disconnect and remove existing equipment, install new systems, start up, test, and walk the homeowner through everything before closing out.
• Install, modify, and fabricate ductwork to properly deliver airflow throughout the home, including trunk‑and‑branch and flex duct systems.
• Run and connect refrigerant line sets, condensate drainage, electrical connections, and thermostat and control wiring on every job.
• Install ductless mini‑split systems including wall mounts, ceiling cassettes, multi‑zone line sets, and proper drainage configurations.
• Replace and install hot water tanks, including gas and electric units, proper venting, connections, and safety compliance.
• Commission every installed system before leaving the jobsite: verify airflow, refrigerant charge, superheat and subcooling, safety controls, and proper operation across all modes.
• Identify and communicate any additional needs, scope gaps, or field conditions that could affect system performance or customer satisfaction.

Technical Knowledge & Problem Solving:

• Apply a strong working knowledge of residential HVAC systems to troubleshoot installation challenges and make real‑time decisions that keep quality high and jobs moving.
• Read and interpret equipment manuals, wiring diagrams, load calculations, and installation guides to execute every job correctly.
• Understand refrigerant handling: recover, evacuate, and recharge systems in full compliance with EPA Section 608 requirements.
• Recognize when a system is performing correctly and when it is not, and take ownership of getting it right before leaving.
• Stay current on equipment, technology, and best practices. Comfort Systems of Montana invests in ongoing training and we expect our people to bring that knowledge into the field.

Crew Leadership & Mentorship:

• Lead install crews on residential retrofit projects, assigning tasks, directing the work, and reviewing workmanship throughout the job.
• Mentor apprentices and junior installers, teaching proper techniques, professional habits, and the standard we hold every install to.
• Hold yourself and your crew to a high bar on quality, cleanliness, and customer interaction at every site.
• Share what you know. A stronger team makes everyone better.

Customer Interaction & Jobsite Professionalism:

• Communicate clearly with homeowners throughout the installation: explain what is being done, answer questions, and make sure every customer feels confident and taken care of.
• Maintain a clean, organized, and safe worksite on every project from start to finish. The condition of the jobsite reflects the company.
• Represent Comfort Systems of Montana with professionalism, integrity, and a genuine desire to deliver a great experience on every job.

Documentation:

• Complete accurate job documentation in ServiceTitan: time logs, materials used, change orders, start‑up checklists, and close‑out sign‑offs.
• Follow all OSHA safety standards, EPA regulations, and manufacturer guidelines on every job.

Qualifications

• 3+ years of hands‑on residential HVAC installation experience with a strong focus on retrofit and changeout work.
• Proven experience installing and commissioning furnaces, central air conditioners, heat pumps, ductless mini‑split systems, and hot water tanks.
• Strong working knowledge of ductwork fabrication and modification, refrigerant line sets, electrical connections, and thermostat and control wiring.
• EPA 608 Certification required.
• Ability to read and interpret equipment manuals, wiring diagrams, and installation specifications.
• Strong troubleshooting instincts. You can diagnose a problem, adapt in the field, and execute a clean solution.
• Comfortable with technology: tablets, digital gauges, and ServiceTitan or similar field management software.
• Strong communication skills with homeowners and teammates. You represent Comfort Systems of Montana on every job.
• Detail‑oriented and committed to clean, high‑quality workmanship on every install.
• Valid driver's license and a clean driving record required.
• Physically capable of performing the demands of the role: lifting, climbing, working in attics and crawlspaces, and operating in variable Montana weather conditions.

Benefits & Culture

• Competitive pay: $32.00 to $50.00 per hour, dependent on experience and qualifications.
• Overtime available. We stay busy year‑round and we pay you for every hour.
• Take‑home company vehicle provided.
