Service Categories and What They Include

Commercial systems have unique needs—larger loads, different equipment types, and compliance requirements. Our commercial services focus on rooftop unit maintenance, system balancing, preventive contracts, and rapid response for business-critical failures.

Why commercial services matter: Minimizing downtime and maintaining efficient commercial systems protects operations and occupant comfort.

Commercial HVAC Services

Proper installation is as important as product selection. We perform load calculations, duct evaluations, and site assessments to select equipment that fits your home or commercial space. Whether installing high-efficiency furnaces, modern heat pumps, variable-speed air conditioners, or ductless systems, our goal is reliable performance and energy-efficient operation.

Why installation matters: Correct sizing and professional installation ensure optimal efficiency, comfort, and system longevity.

What we provide:



  • Accurate load calculations (Manual J)
  • Equipment selection guidance
  • Code-compliant installation and safety checks
  • Manufacturer warranty coordination

HVAC Installation

Routine maintenance keeps systems running at peak efficiency and reduces the likelihood of breakdowns. Our maintenance packages include filter replacement, safety checks, coil and blower cleaning, refrigerant checks, lubrications, and performance tuning.

Benefits of maintenance:


  • Lower operating costs
  • Fewer emergency repairs
  • Extended equipment life
  • Consistent comfort and reliability

HVAC Maintenance

We service both gas and electric furnaces, addressing ignition systems, heat exchangers, controls, and airflow. For older systems, we provide replacement options that focus on efficiency gains and better comfort control.

Why heating matters: Reliable heating is essential for safety and health during Montana winters. A properly serviced furnace prevents breakdowns and maintains safe operation.

Heating Services

Air conditioning services include refrigerant system repair, condenser and coil cleaning, compressor replacement, and installations of energy-efficient systems. We also address airflow issues resulting from dirty ducts or improper sizing.
