Ductless Mini-Split Installation in Menifee, Murrieta & Temecula
Have a garage, addition, or older home with no ductwork — or a room that's always too hot? A ductless mini-split delivers efficient, room-by-room heating and cooling without tearing into walls. Left Coast Air installs and services ductless systems across Riverside County.
What Is a Ductless Mini-Split?
A ductless mini-split connects an outdoor condenser to one or more indoor air-handling heads through a small refrigerant line set — no ducts needed. Each indoor head conditions its own zone, so you can keep a bedroom, garage, or addition at exactly the temperature you want without over-cooling the rest of the house. That zoning is what makes them so efficient.

When a Mini-Split Makes Sense

Ductless Mini-Split FAQs
What is a ductless mini-split and how does it work?
A ductless mini-split pairs an outdoor condenser with one or more indoor air-handling heads connected by a small refrigerant line — no ductwork required. Each head heats and cools its own zone independently, so you can set different temperatures in different rooms.
When is a mini-split a better choice than central air?
Mini-splits shine in homes without existing ductwork, room additions, garages and workshops, converted spaces, and rooms that are always too hot or too cold. They avoid the cost and duct losses of running new ducts, and they let you cool only the spaces you use.
Can one outdoor unit run multiple indoor zones?
Yes. Multi-zone systems connect several indoor heads to a single outdoor condenser, which is common for whole-home ductless setups or additions with more than one room. We size the system to the number of zones and the load of each.
What ductless brands do you install?
We install and service Daikin ductless systems along with other major brands. As an independent contractor we recommend the system that best fits your space and budget.
