MRCOOL® DIY® 5th Gen 3-Zone Ductless Mini Split (6K+9K+9K)
The MRCOOL® DIY® 5th Generation 24,000 BTU 3-Zone Wall Mounted Mini Split delivers professional-grade, multi-room comfort to your home without the need for an HVAC technician. This tri-zone system pairs a high-efficiency 27K BTU condenser—featuring structural headroom to drive up to 4 zones total—with one compact 6,000 BTU and two versatile 9,000 BTU wall-mounted air handlers. Using patented pre-charged Quick Connect® line sets filled with eco-friendly R-454B refrigerant, the configuration guarantees a seamless, leak-free installation without demanding professional trade labor, lineset charging, or mechanical line vacuuming steps.
System Highlights
Three Independent Zones: Control temperature in three rooms separately; each air handler runs on its own schedule and setpoint with flexible sizing for mixed-capacity space requirements.
Flexible Zone Configuration: One 6K zone plus two 9K zones for optimal coverage in homes with one smaller room and two medium-sized rooms.
Expandable 27K Condenser Chassis: Deploys out of the box as a robust tri-zone system, leaving ample reserve capacity to hook up one additional air handler as your living layout expands.
True DIY Installation Workflow: Patented pre-charged Quick Connect® lines completely eliminate the need for vacuuming or professional HVAC assistance. Includes robust DIYPRO® cabling.
Smart Ecosystem Control: Full out-of-the-box integration via Amazon Alexa, Google Assistant, and the dedicated SmartHVAC mobile app for detailed remote zone tuning.
Engineered for homeowners who require balanced, high-efficiency climate control across three varied residential zones, offering future expansion flexibility from a single centralized 27K condenser framework.

"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."
"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."

Thanks for the service!
"Here are 2 pictures of the glue tank in our shop. I hesitated to send anything as it is not in its final place but perhaps it's good enough for you. We are using it for our drawer box station and assembly station. Thanks for the service!"
"haven't had a chance to use it but it looks like a well built product have a few projects down the road and I know this will meet my requirements. so hats off to your team! David"

Both Tools Work Great
"Both tools work great and are real time savers . The two tools that I received from your company were replacements for the exact same tools that I've used for the past years, I think its safe to say 20+ years. Extremely pleased with product and service."
"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."
"I believe they are working well judging by none of the guys have said anything about them other than a thank you for swapping them out for them hahah. So thanks for checking in."
