- High efficiency cooling and heating
- Quiet operation
- Great for garages, workshops and casitas
- Lower electric bills than space heaters or portable ACs
Installation Steps
Load Calculation
The installer sizes the unit based on square footage, insulation, windows and sun exposure, which matters greatly in west-facing desert rooms.
Placement
The indoor head is mounted on an interior wall with open airflow. The outdoor condenser is placed in shade where possible, since direct sun reduces efficiency.
Line Set and Commissioning
Lines, drain and wiring pass through a small wall opening. The installer vacuums the lines, checks for leaks and tests performance.
Single and Multi Zone Options
A single zone unit serves one space, while a multi zone system cools several rooms from one outdoor unit.
How to Choose an Installer
Hire a Nevada licensed contractor with manufacturer training. Request a written load calculation, model numbers and warranty terms.
