Installation Notes from Our Crew

KEEN Multizone Ductless

KEEN systems install like standard mini-splits with quick-connect linesets. The AI-driven indoor units calibrate automatically during commissioning. R-454B is mildly flammable (A2L) and requires EPA Section 608 certification. Wi-Fi module included for app control. Typical install: 1 day for single-zone, 2 days for multi-zone.

LG Red

LG Red is the newest addition to our cold-climate lineup. The install process is similar to Mitsubishi mini-splits. Our crews like the built-in diagnostics — the system can flag issues before they become problems. The ThinQ app setup takes about 15 minutes post-install. We're seeing great performance in the field so far, especially the LGRED low-temperature capacity.
