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.
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®!

*Shipping Policy
I ordered a HVAC system and it arrived in a timely manner and with no apparent issues. I thought the system was defective once installed but it was the installers fault who wired it wrong. My only issue would be the fee (30% I believe) to return a defective item within the 30 day return policy. If it is defective the customer shouldn't have to pay a fee to return an item that is not operating as designed. Other than that this is a good company.
Installed my own central HP system. It was a bit of work but nothing beyond a person with basic mechanical and electrical skills. It took me a while because I had to remove the existing electric forced air furnace from a pretty tight place. Some custom sheet metal work and a bit of custom electrical too. Worked perfectly when powered up and I actually like the thermostat provided, although I wish it was clearer how to set up a temperature set-back schedule. Pre-charged refrigerant piping was something new and I liked that too. The best thing is that my electric utility forked out $4,000 and that paid for the unit!
Installed with ceiling cassettes... Quiet and keeping us cool so far !
Very good customer service will be buying from them again
Was easy to install. Directions were easy to follow and unit is working great
