    Effortless Installation and Outstanding Customer Service

    Installing 2 zones was quick, taking only 9 hours. The system works flawlessly, keeping our house cool all summer. We initially ordered a pre-charged line set that was too short, but Dream Kitchen Home promptly contacted us and corrected the order within an hour, impressing us with their efficiency and excellent customer service. We'll definitely recommend this product and company.

    Unmatched Comfort and Efficiency!

    I recently purchased the Mr Cool Mini Split System, and I'm thrilled with its performance! Dream Kitchen & Home was excellent with communication and delivery. The installation was a breeze, and the system quickly transformed my space into a comfortable oasis. The sleek design and quiet operation exceeded my expectations. It's energy-efficient and provides precise temperature control. I highly recommend the Mr Cool Mini Split for anyone looking for a reliable and efficient heating/cooling solution.

    Electrician Needed

    A bit complicated, but thorough literature. Started right up with no issues. Took away one star for the significant shortcomings of the electrical service connections. There are almost no directions for the electrical connection and the provided terminals for the connections are not properly sized for the specified 8 gauge wire. They are the same size as the evaporator terminals. Needed licensed electrician for this. Overall good product!

    Fantastic Units

    These Mr Cool units are fantastic! Once I put the one unit in, I knew immediately that this was the way to go. These things are quiet and super efficient. The instructions are easy to follow for anyone handy looking to save alot of money. Also the Youtube videos help. The app works great and easy to configure. Tracy from Dream Kitchen & Home was a pleasure to work with as well. Quick responses and professional. I definitely recommend, don't hesitate if you're on the fence about it.

    Foolproof Installation

    Wonderful setup! The installation is pretty easy and almost foolproof. The performance is better than I had expected and it's extremely quiet. I'm actually planning on redoing the HVAC on my daughter's home within the next few months. Definitely would recommend to anyone with at least a small amount of mechanical ability. Dream Kitchen & Home had the best pricing by far.
