            "Mr Cool Mini Split: Unmatched Comfort and Efficiency!"

            I recently purchased the Mr Cool Mini Split System, and I'm thrilled with its performance! Premium Home Source 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.

            Mrcool 3 purchases

            This the 3rd time I purchased a Mrcool system from Premium Home Source for my wood shop, my daughter's house and my house. No problems with the purchase as well as the DIY installation.

            Just installed this morning!

            The unit was turned on for the 1st time and boy it was so quiet I literally had to make sure the fan was spinning outside. the unit and air handlers cool very quickly. I also tested the heating it worked superb. I wont be using this until summer time gets here honestly. that's my main purpose for purchasing it. Living in the deep south requires good A/C. Premium Home Source customer service is also top notch. I would recommend anyone to give them a try. THEY ROCK!

            Best $ spent in a long time

            Best $ spent in a long time. Super easy install even for this 62 y.o. female. Had to have grandsons lift the units up in place but if you can read you can install this yourself. If I could change anything I would make a simpler remote with an on/off, temp up / down button and mode. I won't be using the sleep or other features the unit offers and those buttons are just cluttering up the remote. The overall system works fantastic though - couldn't be happier with the cooling - and the system is very VERY quiet
