MRCOOL DIY questions, answered

Can I really install an MRCOOL DIY mini-split myself?
Yes. MRCOOL designed its DIY series for homeowner installation, with no special tools or training needed. The line sets come pre-charged with refrigerant and use Quick Connect® fittings, so there's no vacuum pump or refrigerant handling. Electrical hookup should follow your local code, and many areas require a licensed electrician for that part.
What size mini-split do I need?
MRCOOL's general guide for wall-mounted units with 8 ft ceilings: 6K BTU up to about 200 sq ft, 9K up to 400, 12K up to 550, 18K up to 800, 24K up to 1,050 and 36K up to 1,550. Insulation, windows, ceiling height and climate all change the answer, and MRCOOL recommends a professional load calculation for best results.
Do I need 115V or 230V?
In the 5th Gen DIY single-zone line, the 9K and 12K run on 115V. The 18K, 24K and 36K need 208/230V. Check the spec sheet on each product page for the circuit size.
Single zone or multi-zone?
A single-zone system has one indoor unit for one room. A multi-zone system runs two to five indoor units from one outdoor unit, so each room can be set to its own temperature. See our multi-zone systems, or call us and we'll help size each room.
What warranty comes with it?
The warranty comes from MRCOOL. For the 5th Gen DIY condensers, MRCOOL lists a base warranty of 5 years on parts and 7 years on the compressor. See MRCOOL's warranty terms for registration and installation requirements.
How long does shipping take?
Orders placed before 2:00 PM ET are handled in 1–3 business days, and transit takes 1–10 business days, so most orders arrive within 2–13 business days. Shipping cost is shown at checkout. You'll get tracking by email as soon as it ships. See our shipping policy.
Can I return it?
Yes, and we don't charge restocking fees. Contact us first at info@ironlinetools.com or (888) 308-5580, and see our refund policy for the details.
Do you offer financing?
Pay over time with Shop Pay Installments at checkout, subject to approval. Questions? Call (888) 308-5580, Mon–Sun 7:00 AM–7:00 PM Central.

Just what I needed

"Saw works great. Just what I needed. You may want to update the specs though. It says 110v but it’s 220v. I don’t think it will an 10” saw blade either. Haven’t tried but I don’t think it’s set up for one like it says. Ordering process was nice and easy. Thank you."

Built for 24/7 Production

"Got the JLT #717C for our shop and it’s an absolute beast for narrow stile doors. The 2-second squaring cycle is legit—we’re easily pushing 100+ perfect doors a day now without stressing over glue joint alignment. Setup is super fast with the pin system, and the heavy-duty build takes daily abuse without losing accuracy."

Mike T., Shop Manager Field Verified

Quiet, Fast, and Totally Worth It

"Bought this California Air Tools compressor for the shop and it’s an absolute game changer. It’s incredibly quiet—you can actually have a normal conversation right next to it without yelling. It fills up fast, keeps up with all our nailers and blowguns with zero issues, and the oil-free pump means no maintenance. If you're tired of loud, annoying compressors ruining the vibe on your floor, grab this bad boy. Worth every penny."

Heavy Duty & Precise

"Brought this Jet 16" x 40" Engine Lathe into the shop recently and it’s an absolute beast. The 3-1/8" spindle bore is exactly what we needed for turning larger bar stock, and the geared head runs incredibly smooth from 25 all the way up to 1,800 RPM. It handles our heavy daily metalwork without breaking a sweat, and you can see how solid the build is right in the photo. If you need a reliable 3-phase lathe that holds tight tolerances all day, grab this bad boy. Worth every penny."
