What Mini-Split Systems Are and How They Work
A ductless mini-split system moves heat rather than generating it. In cooling mode, the system pulls heat from the indoor space and transfers it outside. In heating mode, it reverses the process, extracting heat from the outdoor air and moving it inside. This refrigerant-based heat transfer is significantly more efficient than resistance heating, and it works reliably even when Las Vegas winter nights dip into the 30s.
The system has two main components: an outdoor condenser unit and one or more indoor air handlers mounted on the wall, ceiling, or floor of the space being conditioned. The two units connect through a small conduit that runs through the wall, carrying refrigerant lines, a power cable, and a condensate drain line. No ductwork. No major construction. In most cases, installation is completed in a single day.
Las Vegas conditions make mini-splits a particularly strong fit. Homes with additions, converted garages, sunrooms, or casitas that are not connected to the main duct system benefit immediately from zoned control without the cost of extending ductwork. Older construction with undersized or deteriorated ducts often delivers better comfort through a targeted mini-split install than through another round of duct patching.
