Installing a MRCOOL DIY Ductless Mini Split is already a very simple process. To make sure your installation goes extra smoothe, we asked the members of our team for their top tips for installing a DIY mini split. We took the best answers and compiled them in this short list for you.

Top 5 Tips for Installing a MRCOOL Ductless Mini Split

1. Get a Helper

While you can definitely get away with installing a ductless mini split by yourself, we definitely recommend you get a helper or two to give you a hand. For the indoor unit especially, you will want to make sure you have someone helping you level the mounting bracket and attaching the unit to the mount.

2. Make Things Equidistant

To maximize cooling efficiency in all your rooms, you will definitely want to consider how you position your mini split system. While adhering to the positioning requirements in the installation manual, you should also think about the distance between the condenser and the indoor air handlers, and make them as equidistant as possible.

In a 4-zone mini split system, for example, you should opt for distances of 25, 23, 28, and 27 feet between your indoor units and the condenser, compared to distances of 16, 34, 49, and 10 feet. This will make sure that all your rooms are getting cooled at the same rate.

3. Check for Leaks

When connecting the indoor and outdoor parts of your mini split system, you should always check for leaks. Especially after connecting the Quick Connect Line Sets, you should use a spray bottle with soapy water on all the connection points to ensure you have no air bubbles. If you do find any leaks, stop the installation and contact your MRCOOL dealer to get a replacement. If you're not sure how to check for leaks, you can find more information in this video.

4. Do Not Play the Electrician

A MRCOOL Ductless Mini Split is not like a microwave where you can just plug it into an outlet. These systems are usually connected to a disconnect box, via a whip, which then needs to be wired to the main breaker box of your home. Unless you are a licensed professional or have experience running these kinds of power extensions, then do not attempt this part of the installation. Rather than playing electrician, call a professional and have them do it for you.

5. Activate the Warranty

MRCOOL offers the best warranty in the HVAC industry. Make sure you take advantage of it by registering your unit.

If you still have questions about your MRCOOL mini split, reach out to our team, and they will get you the answers you need.

Worked perfectly and so quiet! These units are

Worked perfectly and so quiet! These units are so underrated!

What a great product to make the installation look professional

What a great product to make the installation look professional , was easy to use and install and love the look after it was installed , it also had different pieces to finish it whether staright out or angled out , I used the straight out and it looks great.

DIY forsure

The whole install was easy as long as you pay attention to detail and follow the instructions. Take your time. My only complaint is the installation of the USB wifi module. You need a screwdriver to pry open the compartment. I pried as far as I could and it would not open. Had to call to confirm this was how to open it. Confirmed! Come on MrCool, lets come up with a better way to open these points without needing to take a pry bar to it. The risk of breaking plastic parts is too great. It was a daunting task with my $2900 unit.

Love my Mr. Cool

I ordered the Wall mount bracket, the 9000 btu unit and the cosmetic coverings. Could not be more happy with my unit. Super easy to install, great instructions, and it works fantastic. Delivery was in a timely manner, the boxes were all intact and looked well packed. Whisper quiet, I use it in a room where i regularly sleep. Love it!!

We have gotten the unit installed and started-up

We have gotten the unit installed and started-up. All systems functioned well on the initial start-up. We are very happy with the units construction.

Thoroughly IMPRESSED!

Thoroughly impressed! This brand was recommended to me by our contractor. I am so thankful we took their advice. This was a fraction of the cost for similar units and works fantastic!

This is the ninth one I have installed

This is the ninth one I have installed. They work great!!! I turned My Freind that does mitsobichi mini splits into installing Mr cool!!!!

Everything was as advertised!

Everything was as advertised. Delivery was speedy and easy. Easy setup. Mine was a replacement of a Daikin split unit installed by a HVAC professional that only lasted 2 years. So I removed the old unit and installed the Mr. Cool unit by myself. I have no HVAC training. All assembled by watching the Mr Cool installation video. Working great so far!
Very satisfied!

Unit works great

Unit works great. Set it and forget it.i love it!!

Great DIY unit

Instructions were a little out of order, read everything front to back 2-3 times before starting install. If you do that you will have no problems, mine had no refrigerant leaks and started right up and cooled the space as intended. Great DIY unit, one day install.

Worth the $

I got it in and its made my Arizona room totally livable. In fact I have to raise the temp setting so it doesn’t get too cold. Very quiet! I believe I saved several thousand dollars versus using a AC contractor.

I’m handy and 69 years old and found the installation process taxing. I completed the job over 3 mournings

Worked great

Works great

Easy install works great so far used only air for now.

Great Product

We love it, not only does it protect the line set, it really dresses the installation up.

Installation manual needs to be updated to include 5th gen products.

New 36000 BTU Mini Split system

Delivered on time with no damage. Instructions fairly clear. Actual DIY installation went smoothly. Although home owner must have an aptitude for such a project. Sales personnel top notch. MRCOOL telephone technical help desk was, well, helpful sorting out a misprint in the manual concerning power requirements for my unit. Project took three days to complete by myself except I had a friend help to lift the outside hefty condenser unit onto the stand. Operating wonderfully for two days now. However it will take me a little time to sort out all the functions of the remote control. Overall, a good experience. Thanks for asking.

Happy with my service

I had a hvac tech install the unit I bought. It was very simple and easy for him to do everything. Now I know alot more about hvacs too!

Put in our closet and haven't had to look at it since!

The unit fit perfectly for what my wife and I were looking for. After it was installed we haven't had a single issue and feel like we are able to have peace of mind with the quality of how well it runs.

Fast shipping and install time

I was in a hurry to have this get installed and the team at MRCOOL HVAC Supply helped me do that. I would suggest purchasing from them if you're in a rush!

Great Buy

I think installing it was pretty easy based off the looks of it. I watch the HVAC tech install everything and it looked simple. Only took an hour and then was able to start the unit up.

Nice looking unit that fits my space

When I needed a new air handler I was in a bit of a panic. Thankfully MRCOOL HVAC Supply fulfilled my order in the same day and I recieved it in only 3 days. Really happy to work with you guys. You saved the day!

Very happy with the entire process of purchasing and installing

I had never bought a MRCOOL unit before so I did'nt know what I was getting myself into. However, it seems as though everything I needed was in the unit I bought so I have a very high level of respect for the brand now. I will be buying MRCOOL units going forward now.
