MRCOOL DIY Multi-Zone 5th Gen 36K BTU Three Zone Ductless Mini Split with Ceiling Cassettes 12K + 18K + 18K – A Heating and AC System You Can Install By Yourself!

MRCOOL DIY Series Ceiling Cassettes provide efficient heating and cooling while remaining out of sight and discreet, making them a perfect fit for any space. The cassette features an easy, low-profile installation and can be recessed between all types of joists on 16 inch centers, including pre-manufactured I-joists. This makes it a perfect option for both new construction or retrofits. It doesn’t have strict installation requirements like other ceiling cassettes, so you’re able to install it in the location that suits you best, without using ductwork or wall space. The cassette works with the MrCool® DIY® Quick Connect® line set and the No-Vac® Coupler to increase the length of the line set. Not only does the unit offer quiet operation and multiple operating modes, but it also features the Elevation function that lowers the filter panel for easy air filter maintenance. Purchases of the MrCool® DIY® Series Ceiling Cassettes are protected by a limited lifetime warranty in addition to a 7-year compressor warranty and 5-year parts warranty.

The MRCOOL DIY 5th Gen Multi-Zone 36,000 BTU 23 SEER2 3 Zone Ductless Mini Split System is ideal for homeowners looking to efficiently heat and cool three rooms with larger square footage. With its DIY-friendly design, this system allows you to install everything yourself without the need for special tools or HVAC training. The included 36K BTU condenser powers the entire system and is backed by a 7 Year Compressor Warranty (with optional lifetime coverage) and a 5 Year Parts Warranty.

MRCOOL DIY 5th Gen Multizone 36,000 BTU systems can support up to five indoor units.

Feel free to mix ceiling cassette air handlers and wall mounted air handlers together in a system by visiting Building Your Own Custom Mini Split System.

The MRCOOL DIY 5th Gen 3-Zone 36,000 BTU 23 SEER2 (12K + 18K + 18K) Ductless Mini Split System with Ceiling Cassette units is easy to install and requires no special training or expensive specialty tools. The DIY system includes Quick Connect lines that are pre-charged with eco-friendly R-454B refrigerant. Thanks to the Quick Connect line set, you don’t have to hire an HVAC technician to complete the install. We also have simple video instructions on how to install a DIY Multi-Zone unit yourself!

The MRCOOL DIY Multi-Zone 36,000 BTU 23 SEER2 3 Zone Ductless Mini Split System can cool through the Summer, heat through the Winter, and dehumidify through the wet seasons. Plus, you can quickly check the temperature of each room in your home from the easy-to-read digital display or from the MRCOOL Smart Controller mobile app. The display on the front of each indoor air handler unit can also display troubleshooting codes and alerts, so you are always aware of any issues with your system. Operate each unit wirelessly with either the included remote or with the MRCOOL Smart Controller app for Apple or Android devices. You also have the ability to control your mini-split unit with Amazon Alexa or Google Home.

The three MRCOOL DIY Multi-Zone air handlers included in this set provide directional control of the heated or cooled air. This distributes the air evenly so everyone in the room can stay comfortable. If you are in a situation that requires forced cooling, you can set your MRCOOL DIY System to manual with the button located on the right side of the unit under the front panel. In this emergency operation mode, you can test the cooling operation of your unit after installation or to complete a maintenance task.

In auto mode, each unit provides air for your home at your desired comfort level. Set your desired temperature, and the HVAC unit will determine how much heat or air conditioning is needed. You can also set this system to a drying function, which will continue to control the space’s air temperature while dehumidifying.

Use the sleep mode at night to save money on your utilities bills and use less energy. Sleep mode operates in an 8 hour window once turned on.

The MRCOOL DIY Multi-Zone 36,000 BTU 23 SEER2 Three-Zone Ductless Mini Split Air Conditioner System – 12K + 18K + 18K comes with many options, so you can customize your system based on your needs. Limit your energy usage and save money on your utility bill by using the system’s timer function. If your system begins to run low on refrigerant, an alert will appear on the easy-to-read display on the front of each air handler, letting you know there may be a leak. If you desire to keep a room quiet and minimize lighted alerts, you can mute each indoor unit. By muting the system, the buzzer for alerts will not sound and the LED lit display will turn off. Should the unfortunate event of a power outage occur, the MrCool system will automatically shut off and then back on with the same settings once power returns.

Easily maintain your MRCOOL DIY Multi-Zone 36,000 BTU 23 SEER2 Three-Zone Ductless Mini Split Air Conditioner Unit with alerts and reminders. Any troubleshooting codes will appear on the front display and the user manual contains an index for common codes. Air filter cleaning alerts are automatic, and you can easily keep the minimal indoor units clean with a dry or damp cloth.

LONG DESCRIPTION
The brand new 5th Generation MRCOOL® DIY® 36k BTU Multi-Zone Ductless Mini-Split Condenser is the right choice if you need immediate, effective comfort that won’t break the bank! This system, which can be installed without the assistance of an HVAC professional, is one of the most efficient and innovative HVAC options on the market. With this condenser, you’ll be able to heat and cool up to 5 different spaces equaling around 1,500 square feet, meaning you can potentially heat and cool an entire home with just one mini-split system! Our DIY® Mini-Splits are able to forgo the evacuation and charging process because our patented Quick Connect® line sets are pre-charged with R-454B refrigerant, a more efficient and eco-friendly refrigerant than R-410A, which we have previously used. These line sets are sold separately. This unit achieves a SEER2 of 23 and an HSPF2-4 of 9.9. These fittings make installation an incredibly safe and simple process, allowing you to save a lot of time and money. There are a variety of features to explore once the system is up and running. One of them is the ability to integrate your system with the SmartHVAC app, allowing you to control your comfort with the touch of a button. You can even go a step further and link your Amazon Alexa or Google home for touchless operation. With the app, you can set each zone’s temperature, set schedules for each unit, monitor your system’s energy usage, and more. There are even more features to explore that will help you customize your comfort to be exactly what you want. We’ve got your back in the unlikely event that your system malfunctions. Your system will come with a 5 year parts warranty and a 7 year compressor warranty, and if you enroll in the MRCOOL® Care Program, you’ll be able to enjoy the Limited Lifetime Replacement warranty! For the best comfort you’ve ever felt and a sense of accomplishment as icing on the cake, choose the MRCOOL® DIY®!

Great for work
Style: 7 in 1 【1 HDMI】
I bought this to use with my MacBook for work, and it’s been a really useful all-in-one hub. One of the biggest advantages is not having to carry separate adapters for HDMI, USB devices, and SD cards. It makes it much easier to connect everything I need at my desk or when working away from home. The HDMI connection worked well with an external monitor, and the USB ports have been useful for keyboard/mouse and flash drives. The pass-through charging is also a big plus since it lets me keep my MacBook powered while still expanding the number of ports available. That makes a big difference if your MacBook already has limited ports to begin with. I also like that it’s compact and easy to keep in a laptop bag, so it works well for both a desk setup and travel. It can get a little warm during longer use, but that seems pretty normal for a small hub doing multiple things at once. Overall, this has been a helpful and convenient accessory for turning a MacBook into a more practical work setup.

My experience with the Anker Products is Great.
Style: 7 in 1 【1 HDMI】
Anker USB C Hub (7-in-1) I now have several Anker Products in my home. These folks just know how to build products. Affordable and durable, stable and easy to use. This 7 in 1 is all Plug and Play. I am using an external power supply, and this product delivers it to all of my connected devices. The stability of every thing plugged into the USB Ports keeps everything connected just as it should. I recommend the Anker Product Line and this product in particular. SO, if you're in need of additional USB Ports, go with Anker.

Solid; long lasting
I use this adaptor to hard wire an ethernet internet connection straight into a Samsung Galaxy S10+ with PD (charges phone while connected). I also use an S8+ which works, too. This is a great option for those of us who understand the dangers of being exposed to low-powered microwaves all day and night (AKA Wi-Fi). While hard wired to ethernet, you can enjoy the internet with airplane mode on, which is a big plus! I've used several different branded adaptors (the ones without PD kill your device's battery QUICKLY) for this purpose, and this Anker outshines them all. Most other brands (I've tried Belkin, Ugreen, and some other somewhat obscure brands) work fine for a short time and then begin to get spotty, losing and regaining connection intermittently until crashing and not working at all over a short period of time, usually not longer than 3 to 4 months if you're real lucky. However, I've had this Anker for nearly a year (10 months and change), and it's still going strong. Now, it's not perfect. It does lose connection from time to time and then regain connection just like the others, but nowhere near as frequent, and if you are mindful of the orientation of the cords and take care not to twist or put torque on them once they're connected to a device, it usually keeps connection very nicely. Be sure to put the device in the proper orientation through which you'll be looking at it, and THEN connect the adaptor (don't connect the adaptor and then have to roll the phone over to look at the screen, as this is the fastest way to kill the adaptor and loosen your phone's charging port). When first attaching, I plug the ethernet cable into the adaptor and use a hair-tie rubber band to wrap around the end of the ethernet cable, making sure it's tight with no slack, then I secure it around the BASE of the type-C cable coming out of the opposite end of the adaptor (see attached picture). Then LEAVE IT. If you incessantly disconnect and reconnect this adaptor, I guarantee it will not last as long. As for the features of this adaptor, I can only speak on the ethernet connection, the PD port, and the type-C 5gbps port. The PD port is nice because if you try connecting to the internet and doing pretty much anything without it, your device's battery is going to drain quite rapidly. How fast depends on how good your device's battery is to begin with. S10+ probably won't last half the time without PD as it does with PD. Just realize that your device is not going to gain power while charging through the PD port, but rather the battery will merely die at a slower pace, giving you more time before having to recharge your device. The other factor is how long your charging cable is (the shorter it is, the longer the battery will last). Tip: While using PD port, your device will not warn you of your battery about to die since it is technically charging, so if you're doing something important, you had better keep an eye on your battery percentage, lest it dies unexpectedly. I've not used the hdmi port at all, so nothing to speak on there. The 5gbps type-c port is nice if you want to connect an external hard drive while either A: connected to the internet, B: still being able to charge your phone, or both! I use the Samsung Portable SSD T7, and the Anker is great for saving large videos/files straight from the internet onto the external hard drive. The Anker is also good for freeing up space on your phone by moving existing files to the hard drive while continuing to charge your phone (otherwise, the hard drive connects directly to your phone, so your charging port is being used, and if your battery is low, no charging). Also, if you disconnected the ethernet cable from the Anker while moving files to an external drive, I suspect that the PD port would actually add battery percentage instead of merely slowing down the loss of battery percentage. To summarize: - Don't get Wi-fried: use a hard-wired ethernet connection instead! - Great adaptor that lasts longer than all others I've tried. - PD is a must have feature, but your device will still eventually die. - Great for saving videos/large files straight from internet to external hard drive while being able to charge device simultaneously. This Anker is the one you're looking for! Cheers.

Excellent quality with just the right amount and type of connection points I needed!
Extremely good quality. I've used many Anker product over the years and this one didn't disappoint! Needed it to run a laptop on my network in isolation mode and to have accessible connections for ethernet as well as a wireless mouse and extra cooling fan as my laptop has only 1 standard size USB 3.0 port. This is the mini version so It won't necessarily supply enough juice to charge your laptop at the same time (there's another 8 in 1 made by Anker for that) but it can supply enough power to maybe get you through a very trying session, very short term. Super-easy to connect and just works. Fits comfortably in my carry bag too. Very light weight, good heat dissipation although I didn't really have any or at least not much. Compatible with all the connectors you see in the picture. In my case at least, it wasn't a luxury it was a necessity and it proved it's value immediately.

USB ports charge.
Relatively cheap, lightweight, and better than most. It gets warm, but not hot. The Video adapter was immediately recognized by my Macbook and works flawlessly at all resolutions made available (much higher than Windows PCs) I used it both as the recipient of my 65W Mac charger, and the Mac received its power from this device; I also had the 65W Mac charger plugged directly into the Mac, and this plugged into the second USB-C plug on the mac. It works (HDMI monitor) both ways. It says that the ports are not for "charging", however be aware that they do charge when devices are connected, for example my iPhone to the extra USB-C port, or the USB-A port. My Logi back-lighted keyboard lights up too. I don't know why they say it is not for charging. Perhaps it is simply saying there are no ports expressly intended to do charging without connecting to your computer.
