A: Always (if it's efficient).
- Power Surges: Single-speed motors need 4-6x more current just to start up.
- Wear and Tear: Constant cycling "shocks" the system and leads to more maintenance.
- Temperature Swifts: You feel too cold when it's on, and too hot when it's off.
The Variable-Speed Advantage
Modern Variable-Refrigerant (VRF) units, like Airspool systems, are designed to run almost all of the time.
Instead of cycling on and off, the motor slows down to a crawl as it reaches your setpoint. This allows the unit to maintain a perfectly consistent temperature using only a fraction of the power required by a traditional unit.
When it's solar-powered, this "always-on" approach is even better. You aren't "using up" electricity—you're simply taking advantage of the sun's consistent energy throughout the day.
