Mini Split Reviews from Real Customers
See why homeowners love Zone Air DIY mini splits. Real customers share how much they save on installation and energy cost.
"We just can't believe the deal we got! We had contractor's wanting $6,000 to install one of these things, but at $4,000 it was a steal. The DIY install was actually a breeze - just plug and play with the pre-charged lineset, and we were done. Been a month now and our power bills are 40% lower. It really has been a great investment for us."
"Hands down the best ductless mini split on the market for the DIY crowd. It totally outshines our MrCool unit from last year that we installed in the garage. Super efficient, it really packs a punch and didn't even break the first month. Plus the customer service is top notch, and they're actually based in the USA! And let me tell you, the heating in cold climates? Its like a dream come true. Keeps the house warm even at -10°F winter."
"We managed to install this Zone Air mini split heat pump in just 4 hours - its a total breeze to do yourself. We'd also just gotten solar last year, and now we've got this efficiency with this heat pump and we're basically completely off the grid. The 24 SEER2 efficiency is the real deal. Its like our old central air conditioner was ancient compared to this thing."
