Best system out there! Hands down

I have purchased 3 of these units, they are great!!!! love the remote from the phone. I turn it on 30 minutes to and hour before I get on and it's nice inside. The 1st one took me 3hrs to install because I never done this before and I was scare that I was going to make a mistake and mess it up! The other 2 I purchased took less than 45 mins to install. They are super easy ! great product!

Great product, great warranty

I absolutely Love my mini-split! Everyone there at Mr. Cool was soo helpful. Communication was great too! My condenser was exactly 24 feet away from the air handler so the 25ft line sets were perfect - no need to coil them up or anything. The unit itself was really easy to install, though it would be nice if they took the time to Americanize the instructions. For the most part, they are clear, but there were several very nebulous areas. A bigger issue was that they aren't entirely model-specific. The unit itself is clean and works amazingly. I LOVE the ability to turn it on with Siri literally anywhere! I can be at work 30 miles away and tell Siri to turn it on, and it works every time! My ac is nice and cold when I get home. The heater works nicely as well but has only had a couple of chilly days that I've needed it so far. I also bought the line set covers, which were also installed easily and painted really well. I caulked all the openings to keep the critters out. Overall 5 stars and would definitely purchase again.

Awesome system and line sets

I needed a mini-split for my home. Wanted DIY and helped speaking with Alex he explained exactly what I should use and why. VERY knowledgeable, polite and friendly on the phone. I had email confirmations and updates for their Fast shipping. I'll be installing the hardware myself. The 25ft line sets are SOLID - I bent them around a 90 degree wall and had no issues at all. Great line sets and great system

Lionel Fields
Amazing - love it! Perfect for large house

This A/C is amazing! We've had it in for a week and I don't know how we ever lived without it! Small compressor, interior unit looks nice too, and everything is so quiet! Connecting to the internet was a breeze, and MrCool does play nice with Alexa.
Our whole house is quite large and this unit chills the whole house in minutes. It's been so hot this summer we have not tested it's heating ability, but we also have a furnace so we're less concerned about that.

Good Product

Ordered this mini-spit system in mid July and it was delivered July 27. Premium Home Source had a great price - the best I was able to find online when you factor in shipping and all other fees (they were one of the only retailers with free shipping). Easy to install and just finished the wiring. Turned the power on and went through the tests, then set the temperature for cooling the house. The unit kept my entire 2,600 sf house at the set temp by itself. I have a central furnace and duct works running on propane in a well insulated low heat loss house. After a few days of running it looks like electric cost is significantly less than propane cost. Very silent operations both inside and outside. Good functions with remote and wifi through phone app. Very happy so far.
