Amazing Heating and Cooling Unit
on September 16, 2026

[This review was collected as part of a promotion.] The Keystone Summit 9000 BTU 400 square foot mini split AC heat pump. It is an amazing unit that provides both cooling in the summer and heat in the winter. I decide to have it installed in my shed/ workshop. I can now use my workshop any day of the year on the hottest of days and the coldest of days. Is super quiet. You don't even know it's running. Does require professional installation from an HVAC professional. Amazing unit that I would highly recommend and the description is just as described.

[This review was collected as part of a promotion.] Installation of this mini split was done by just one person with easy instructions through the process. I’m excited to use the systems app to operate on a day to day basis. When running the system is quiet and quickly cools down the room. Very satisfied customer!

Great size and scale for an ADU/guest house

[This review was collected as part of a promotion.] This mini-split unit is the perfect size and scale for an ADU/guest house. It’s such a convenient way to condition and heat a space without the hassles of installing ductwork. I love the design of the product as it blends into the walls. As a designer, I really appreciate its compact footprint. The included remote is responsive and easy to adjust the temperature. I love how there’s even an anti-mildew and clean features. Overall, this is the perfect BTU for my garage to ADU conversion, and DIYers, homeowners, designers, and contractors will really appreciate this unit.
