A Mini Split You Can Actually Install Yourself

Anyone selling you a "5-minute mini split install" is talking about one step, not the whole job. Here is the whole job:

1. Pick the wall and mount the bracket. Ordinary drilling and leveling. The bracket, level, and hardware are in the kit. Watch how.
2. Drill one hole through the wall. The included hole saw handles wood, drywall, brick, and cinder block — we tested it on all of them.
3. Hang the indoor unit and feed the line set through. The part where a second pair of hands helps.
4. Connect indoor to outdoor unit. On an Airspool this is the famous five minutes: twist-to-connect refrigerant lines, twist-to-connect communication wire, pre-wired power cord. No vacuum pump, no gauges, no refrigerant work. Watch it done in real time.
5. Terminate the condensate line, wrap the lines, power on. Wrapping and power-on, each covered step by step.

Plan on a day if it's your first time. The parts that take skill on an ordinary mini split — refrigerant connections and wiring — are the parts we've already done for you.

The single most common DIY failure isn't skill — it's the third trip to the hardware store. So the box includes what the job needs:

See everything in the bag, and if you're ordering, measure your line set length first — we build it to your measurement, pre-charged, by the foot.

The connections on the unit itself are homeowner work — that's the point of the design. But if your install needs a new dedicated circuit at the panel, or you're not comfortable working around your panel, hire a licensed electrician for that part. It's typically a small, one-visit job, and it's the right call. Factor it into your plan the same way you'd factor in a helper for lifting the outdoor unit.

Here's the part no other DIY mini split does: an Airspool is a solar hybrid. Add roughly 1,500 watts of panels — about four ordinary residential panels, here's why that number — and it runs on sunshine first, grid power second, automatically. No batteries, no inverter, no permits for a grid-tie, because the panels connect straight to the unit.

You don't have to do the solar on day one. Plenty of customers install the mini split first and add panels later — the solar wire, isolator, and whips are already in the box waiting.

Three things stand behind a self-install:

• Every step is on video. The whole Quick ’n’ Easy^TM install series was filmed on real installs, start to finish.
• A real person answers the phone. Air conditioning specialists in Las Vegas, not a distributor's call center.
• The guarantee assumes DIY. A full year to buy and try it, then four more years where keeping it working is our responsibility — self-installation doesn't void it, it's the expected case.

That combination is why we're rated 4.9 stars by verified buyers — read the unedited reviews, most of them from first-time installers.

Can I really install a mini split myself?

Yes — if the unit is designed for it. The dividing line is the refrigerant connection. If it needs flaring, a vacuum pump, or gauges, it's a pro job. If it's truly pre-charged and hand-tightened, like an Airspool, the hard part is drilling one straight hole.

How long will it take?

A day, first time. The mounting and routing take the time; the connections take about five minutes.

Do I need an electrician?

For a new dedicated circuit or anything at the panel you're unsure about — yes, hire one. For the unit connections themselves, that's what the design solves.

Which Airspool should I start with?

Most first-timers start with the MS12 — 12,000 BTU of cooling and heating, the full kit, and the five-minute connection. Comparing brands first? See how we stack up against EG4 and MRCOOL DIY, or browse the best DIY mini splits of 2026.
