About This Service

Some buildings just can't take ducted central air. There's no attic run, no crawl space, or no room to add one. That's where a ductless mini split earns its place. We install them in mobile and manufactured homes around Oceanside and Vista, in condos and apartments under HOA rules in Carlsbad, and in new ADUs and garage conversions from Encinitas to Solana Beach. A mini split pairs a small outdoor unit with one or more indoor heads mounted on a wall. The refrigerant line set needs only a small hole through the exterior wall, so nothing gets torn open. One outdoor unit can feed several heads, which lets a two story townhome run a head per floor on separate controls. Small spaces are their own puzzle. A 400 square foot ADU needs a right sized head, not the biggest one on the truck. Oversizing makes a room clammy and short cycles the compressor. We size the head to the actual space and put it where the air will reach the whole room. We pull the permit, do the install, and register the equipment warranty in your name. Free estimates on new installs. Call us at (760) 893-6999. A ductless mini split is a heating and cooling system that skips ductwork entirely. A small outdoor unit connects to one or more indoor heads mounted on interior walls, joined by a refrigerant line set that needs only a small hole through the exterior wall. It's the practical option for buildings that can't take ducted central air, including mobile and manufactured homes, condos and apartments governed by an HOA, multi story townhomes that need a head on each floor, and ADUs or garage conversions. We install and service ductless mini splits in Carlsbad, Encinitas, Cardiff, Oceanside, Vista, San Marcos, Escondido, Del Mar, Solana Beach, and Leucadia.

Our Process

1

Walkthrough and Sizing

We measure each room, count the heads you actually need, and check whether your electrical panel can carry them. Sizing comes from the space, not a square foot rule of thumb.

2

HOA Review and Permit

If an association has to approve the work, we help you pin down where the outdoor unit sits and how the line set gets routed. We pull the city permit ourselves.

3

Install Day

We mount the heads, set the outdoor unit, run the line set in a paintable cover, then vacuum and charge the system.

4

Startup and Warranty Registration

We test every head, walk you through the remotes, and register the equipment warranty in your name.
