# Mini Split Installation | CrossBreeze Heating & Air > Ductless mini splits for rooms, additions, garages and ADUs with nowhere to run ductwork. Call 760-715-0523. A ductless mini split is a heating and cooling system that mounts on the wall and connects to an outdoor unit through a small line set, so it needs no ductwork at all. That makes it the usual answer for a converted garage, an ADU, a bonus room over the garage, or an older San Diego house that never had ducts. Each head is its own zone, so you are not paying to condition the whole house to fix one hot room. They also run as heat pumps, which means the same unit covers the handful of cold weeks we get. Sizing matters more than brand here, and we size to the room rather than to a rule of thumb. Eddie does the room survey himself, measuring square footage, sun exposure and how the room actually gets used before anyone quotes a head. CrossBreeze installs mini splits across San Diego, the South Bay and East County, from Mira Mesa out to Chula Vista and El Cajon. ## Key Benefits - We install Mitsubishi, Fujitsu, Daikin and Samsung - Single head or multi head off one outdoor unit - We service mini splits, including ones we did not install - Financing at 2.99% through Housecall Pro - Licensed CSLB #1055889, workers comp carried ## Our Process 1. **Room survey**.

That is the most common reason people call us about them. A ductless mini split needs no ductwork at all, just a small line set through the wall to an outdoor unit, which is why it is usually the only practical option for a converted garage, an ADU or a bonus room that was never on the main system. ### How many indoor heads do I need? One per area you want to control separately. A single room takes one head. A converted garage with a bathroom might take two. We size to the room rather than to a rule of thumb, because an oversized head short cycles, never pulls humidity out, and wears itself out early. ### Do mini splits heat as well as cool? Yes. They run as heat pumps, so the same unit covers the handful of genuinely cold weeks San Diego gets. For most homes here that means one system instead of two, and no gas line into the room. ### Which mini split brands do you install? Mitsubishi, Fujitsu, Daikin and Samsung are the ductless lines we work with most, and we also install Goodman, Innovair and AC Pro. Sizing and the quality of the install matter more to how it performs than the badge on the front does. ### Is a mini split cheaper than extending my existing ducts? Often, yes, especially if the run is long or the attic access is bad. We will price both honestly. If extending the ductwork is genuinely the better answer for your house we will say so rather than sell you the job we would rather do. ### Where do you install mini splits in San Diego County?
