SHORT DESCRIPTION
MRCOOL® 48k DIY 5th Generation 6 Zone Multi-Zone Mini-Split Condenser 230v
LONG DESCRIPTION
We’re excited to introduce our new 5th Generation MRCOOL® DIY® 48k BTU Multi-Zone Ductless Mini-Split Condenser, because it’s better than its predecessor in nearly every way. You won’t need the services of an HVAC professional when you’re setting this unit up, because you can do it yourself, which saves lots of time and money! This condenser enables you to heat and cool up to 6 separate spaces equalling up to 2,000 sq. ft., meaning you’d be able to cover an entire home in the completely efficient comfort of a single DIY® system. You can install this system on your own because our innovative, patented pre-charged Quick Connect® line sets allow you to skip the lengthy and complicated process of evacuating and charging the system. These line sets are filled with R-454B refrigerant, a much more ecological and proficient upgrade from the previous refrigerant used in the last generation. This switch helps the system achieve impressive efficiency levels, like 21.8 SEER2 and an HSPF2-4 of 10. These line sets are sold separately. Once you install your system, you’ll be able to explore the variety of ways you can customize your comfort. For ultimate control, you can integrate system operations with the SmartHVAC app, available for Apple and Android phones, allowing you the ability to set schedules, manage modes of operation, monitor your systems all with the touch of a button. The app even enables you to set up integration with Amazon Alexa and Google Home, meaning you won’t have to move a finger to make your home more comfortable than ever. We pride ourselves on having one of the best warranties in the industry on this unit! Once you install your condenser, you’re entitled to a 5 year parts warranty, a 7 year compressor warranty, and, if you subscribe to the MRCOOL® Care Program, a Limited Lifetime Replacement warranty. The MRCOOL® DIY® is the right choice if you want fast, efficient comfort that won’t let you down!

Buy it you'll love it. You'll realize that you really needed it
Color: Black
Size is perfect for rag, scrubber sponges soap. It's very sturdy love that the block on bottom dryies up all the liquid it's absolutely amazing. It's very convenient, love the way you can organize everything. I'm the kind of person I have to have everything organized that's the way I grew up. I have not seen any signs of rust no where. Highly recommend. It is very very nice.

Funcional but smaller than I thought
Color: B-silver
I liked it and it replaces something around the kitchen sink that was constantly dripping liquid soap dish into the sink making a mess! This new organizes items much better. It's smaller than I envisioned and wish it came with it's own soap bottles dispensers but I found two small ones placing them side by side and it works. Did not use the metal divider. I cannot tell yet the drying speed of the sliding out stone. It's functional at keeping everything hands reach and organized around the kitchen sink.

Nice sink caddy
Color: Gold, Color: Gold
It was exactly as described- looks nice on my counter. I haven’t bought the scrub brush I want yet to put in the taller space but it def dries fast anytime water gets on it. I like the look on my counter space. It’s not flimsy, I like the color of the gold.

Effective!!
Color: Black, Color: Black
This caddy keeps my sink organized. It absorbs the water when I place my sponges on it and its super easy to keep clean. I squeeze as much waster as I can from the sponges so it doesn't wear out. I've had this a little under a year and it has held up exceptionally well.
