MRCOOL 9000 BTU 115V Ductless Inverter Mini Split Air Conditioner & Heat Pump System, 4th Gen Advantage Series - Wall-Mounted AC Unit w/Heating and Cooling for Home, Office & Commercial Space

Works way better than any ac unit I ever gotten. Easy to install. Quiet as heck! My electric bill didnt spike up the fan speed was fast yet quiet. The size is perfect and energy efficient! Very good quality.

I bought this for an apartment room off my house that's 25ft x 15ft. Its the main heat and AC in this room which my oldest son lives. I installed it last summer so we had it thru this whole winter. No problems heating even on 15 degree nights. Didnt even have to crank it up on colder nights to accommodate the colder temps. The coldest night we had here this winter was 9 degrees and windy. It was putting out 120 degree air than night. I have 2 other 18k Mrcool units for the rest of the house which is why i went with this one. Now the 9k dont have that crazy blower fan speed that the big ones have but its comparable air flow of a big window unit. Very efficient due to the variable compressor. One thing I like about mini splits are you can run them off smaller generators in a power outage where a typical heat unit is on a 60 amp breaker and you cant. If your concerned about heating or cooling power just buy a unit one size up. Bigger unit dont work as hard so it pulls less power while maintaining temp.

Wasn’t a terrible install. This unit is not DIY and the line set is not pre charged. You will need an HVAC technician to evacuate the line set. I ran the line set traditionally like a central setup, through the wall into the attic and back into the wall and then out to exterior to condenser for a cleaner look. Electrical was pretty straight forward. This kit did not come with a template either. However, function is flawless and once I’m done with Sheetrock/paint, it will be aesthetically pleasing and will keep us cool all summer :). Also to note, the line set and communication cable are only 16’. Make sure you fill out and email your warranty paper that is included in the package.

Installed one in my shed and it works Amazing in Heat Mode!

When I first got this unit I though it was great. Unfortunately that feeling was short lived. The unit worked fine for 2 years. I only used it for the summer months in my man cave when it was hot outside. Then it suddenly stopped working! I had to get an HVAC Tech to come and check it out. The compressor was shot. When I contacted the company they told me that my warranty had expired and they couldn't help me. The warranty is only 2 years!!! That fact that they only offer a 2 year warranty shows that they know the product is complete crap! I have used small window units that cost much less that have lasted much longer! DO NOT WASTE YOU MONEY ON THIS OVERPRICED CRAP!

This unit has been very problematic. Goes into defrost mode for no reason. Quits blowing hot air for no reason. And then takes forever to get it to go back to working right.I wished I would have bought the EG4

I installed three of these smaller 120 V units in my guest bedrooms. Installation is brainless if you have any level of mechanical ability. I live in a moderate climate rarely below freezing in the winter, 90 degree days most of the summer. These units will feeze you out of the room or cook muffins if that's what you want. Normal room temp is achieved within minutes. The units are dead quiet. Im installing 3 more larger 220V units in the rest of my house and ditching the entire central system. Im not going with the multiple zone sytems for one reason: i figure if a single zone unit fails, i have to spend less than two grand to replace it. If one zone on a big 4 zone unit fails I'm out 5 grand plus. Also the multiple zone units are super heavy. I can pick up the smaller units by myself. Last thing, the difference between 3rd and 4th generation is minor regarding electrical hookups and conduit. For me, the reduced price of the 3rd gen is more important than a "convenience" improvement.

Purchased this for our camp bunkhouse and my brother installed it! He worked for an ac business for years and still does it on the side. The coil started leaking at approximately 1 year and this company won’t send replacement parts due to a licensed ac person didn’t install. I would think someone that has done this for years would qualify. So beware it’s not a long lasting product.
