Ductless Home Solution for Do-It-Yourself Heating & Cooling
The MRCOOL DIY Multi-Zone Series ductless mini-split is the only whole-home mini-split solution that you can install yourself. Simple, easy air comfort in up to four zones.
MRCOOL's DIY Multi-Zone heat pump air conditioner, the latest and greatest iteration of the only ductless mini-split system on the market explicitly designed for amateur installation, is now even more efficient, versatile and easy to install. You don't need special tools or training to install this high-efficiency heat pump.
Between the money you save by installing yourself and the rebates available for ENERGY STAR models, the MRCOOL DIY is the most cost-efficient air conditioner on the market today.
When appropriately sized this system is the ideal DIY solution for room comfort and with the factory-installed low ambient cooling technology it's also the ideal DIY solution for server rooms, greenhouses, and any other application that requires cooling all year.
The MRCOOL DIY includes the new SmartHVAC Wi-Fi control module that features an easier setup process, improved functionality, and works with Amazon Alexa and Google Assistant. If you want great air comfort without paying an arm and a leg for installation, you want an easy-to-use MRCOOL DIY Series ductless heat pump.
There are several combinations of BTU ratings to choose from for the DIY Multi-Zone series.
DIY 3-Zone Includes:
- *27,000 BTU or *36,000 BTU Multi-Zone Condenser
- Wall Mounted Air Handlers (x3)
- Remote Controls (x3)
- Installation Kits (x3)
- 27,000 BTU (9k + 9k + 9k) (*uses 27k condenser)
- 27,000 BTU (9k + 9k + 12k) (*uses 27k condenser)
- 30,000 BTU (9k + 9k + 12k) (*uses 36k condenser)
- 33,000 BTU (9k + 12k + 12k) (*uses 36k condenser)
- 36,000 BTU (9k + 12k + 18k) (*uses 36k condenser)
- 36,000 BTU (9k + 18k + 18k) (*uses 36k condenser)
- 36,000 BTU (9k + 9k + 18k) (*uses 36k condenser)
- 36,000 BTU (9k + 9k + 24k) (*uses 36k condenser)
- 36,000 BTU (12k + 12k + 12k) (*uses 36k condenser)
- 36,000 BTU (12k + 12k + 18k) (*uses 36k condenser)
Note: *If all indoor units (handlers) run simultaneously, their combined BTU output will not exceed the BTU rating of the outdoor unit (condenser).
*Note: MRCOOL DIY 3-zone units use either the 27,000 BTU or 36,000 BTU indoor condenser depending on model. Using the larger 36k condenser will give you more flexibility in the future to upgrade one of your indoor heads for a larger BTU unit. If you have no plans to make any chnages to the set up in the future, choose the 27k unit to cut down on cost.

DIY Quick Connect Line Set
The MRCOOL DIY Quick Connect Line Set is 100% accurately precharged with R410A refrigerant. This makes installation quick and easy with no vacuum required. The MRCOOL DIY® Quick Connect® Line Set is intended for use with the MRCOOL DIY Single or Multi-Zone Units.
NOTE ON EXTENDING LINE SETS: To properly extend MRCOOL DIY line sets, you must match the line set and coupler size with the indoor air handler that you are needing to expand. The MRCOOL Quick Connect Line Sets and line set couplers come in two size options depending on the BTU rating of your air handlers you are needing to extend.
*For example, if you need to extend the line set on a 9k, 12k, or 18k air handler you would need to purchase the DIY Quick Connect Lineset for 9k,12k, or 18k air handlers as well as a matching coupler for the same size air handler. If you are trying to extend the line set for a 24k indoor air handler you would need DIY Quick Connect Lineset for 24k or 36k air handlers as well as a matching coupler for the same air handler. If you are unsure about proper fitment, please give us a call before placing your order.

For extending the DIY QUICK-CONNECT LINESET
When one standard size DIY QUICK CONNECT LINE SET is not long enough, two standard QUICK CONNECT LINE SETS can be combined using our DIY COUPLER to increase the desired length of the QUICK CONNECT LINE SETS.
It is imperative that you get the correct coupler for your lineset for it to be compatible. If your original lineset is 1/4" & 1/2" then you will require the same size coupler and same for 3/8" & 5/8"
Select the DIY QUICK CONNECT LINE SET size to be lengthened (1/4 or 1/2) or (3/8" or 5/8"). Then select the second standard line set with corresponding specifications for combined connection using the coupler (as shown here).
Use a wrench to assemble the coupler with both F1 and F2 on the corresponding lineset. Make sure the thread is screwed to the bottom until it stops (as shown here).
After the connection is complete, cover the F1, F2, and coupler connections with the grey insulating sleeve to help prevent condensation. Slide the insulation sleeves together ensuring no copper wiring is exposed and secure in place using tape.
