Do you work on homes without central air ductwork?

Yes. A lot of older homes in LA were never built with ducts, so we install and service ductless mini-split systems as often as we do central air. If your house has window units right now, we can talk you through what a mini-split setup would actually look like.

Do you handle both home and business HVAC?

We do both. Homes are where we're growing right now, but we still take on commercial jobs — rooftop units, commercial maintenance, the works.

How fast can someone come look at my system?

We're open 8am to 5pm, Monday through Saturday. Call during those hours and we'll get you on the schedule as soon as we can, usually the same week and often sooner.

Ductless Mini-Split Installation Los Angeles: One System for Homes and ADUs Without Ductwork

A mini-split heats and cools without needing a single foot of ductwork — which is exactly why it's become the go-to system for LA's older homes, ADUs, and additions. We'll size it right and give you a straight price before we start.

Intro

Ductless mini-split installation is one of the three things All American Solution does most, right alongside general HVAC installation and repair. See everything else we handle on our HVAC Contractor Los Angeles homepage.

Why Us

Why Los Angeles Chooses All American Solution for Mini-Splits

Between the two partners at All American Solution, there's 15 years of hands-on HVAC experience, a good chunk of it spent sizing mini-splits for houses across LA that never had ducts to begin with — Sylmar, the Westside, everywhere in between. We size every zone properly instead of installing whatever unit happens to be on the truck, and we'll tell you honestly whether one indoor head covers your space or you actually need two.

What a Mini-Split Installation Costs in Los Angeles

A single-zone mini-split — one outdoor unit, one indoor head, covering a room or a small ADU — usually runs $2,500 to $7,500 installed in LA, depending on unit size and how the lines need to run. Whole-home multi-zone systems, with several indoor heads tied to one or two outdoor units, typically land between $7,000 and $15,000. Los Angeles Department of Water and Power customers may qualify for a rebate on qualifying ductless heat pump systems — the amount and eligibility change from time to time, so we'll check what actually applies to your job when we quote it.

One System, Both Heating and Cooling

Every modern mini-split is technically a heat pump, which means it doesn't just cool — it heats too, from the same unit. That matters for LA homes running an old wall furnace and a window AC side by side. One mini-split system replaces both, often for less than the cost of fixing the two of them separately over the next few years.

Built for LA's ADU Boom and Older Homes Without Ducts

Los Angeles is one of the busiest ADU markets in the country right now, and most ADUs never get ductwork run from the main house — there's rarely the room or the budget for it. A mini-split solves that in one shot: one compact outdoor unit, one indoor head, full heating and cooling. It's the same story for garage conversions, room additions, and the older homes across Sylmar, the Westside, and everywhere between that were built before central air was standard.

What Installation Actually Looks Like

A single-zone install usually takes about half a day: we mount the indoor head, set the outdoor unit on a pad or bracket, run a small line set through the wall, connect the refrigerant lines, and test everything before we leave. Multi-zone systems with more than one indoor head can take one to two days. Most jobs in LA need an electrical or mechanical permit, which we handle as part of the installation.

What Los Angeles Customers Say

Don't just take our word for it — here's what homeowners and businesses across LA have to say about working with us.

FREQUENTLY ASKED QUESTIONS

How much does mini-split installation cost in Los Angeles?

A single-zone system usually runs $2,500 to $7,500 installed, and whole-home multi-zone systems run $7,000 to $15,000. The exact number depends on the size of the space and how many zones you need — we'll give you a real price after seeing the job.

Do ductless mini-splits provide heating, or just cooling?

Both. Every modern mini-split is a heat pump, so the same system heats your space in winter and cools it in summer. One unit replaces both a window AC and a separate heater.

Can a mini-split work for my ADU or an addition with no ductwork?

Yes — it's actually the most common system we install for ADUs and additions in LA, since running ductwork from the main house usually isn't practical. A mini-split gives the space its own heating and cooling without touching the rest of your home's system.
