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."

Mike T.
Denver, CO • 12K BTU Single-Zone
★★★★★

"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."

Sarah K.
Minneapolis, MN • 18K BTU Single-Zone
★★★★★

"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."

Frequently Asked Questions About Mini Split Systems

What is a ductless mini split system?
A DIY mini split consists of an outdoor unit and one or more indoor air handling units connected by refrigerant lines and a pre-charged lineset. Unlike traditional HVAC systems that rely on existing ductwork, a ductless mini split system delivers heating and cooling directly to each room through wall mount air handlers, ceiling cassette units, or concealed ducted indoor units. Zone Air mini split heat pump systems use advanced DC inverter technology with up to 24 SEER2 efficiency for year-round temperature control in heating mode and cooling mode.
Can I install a mini split myself?
Yes! DIY mini split installation is straightforward with Zone Air systems. Our pre-charged lineset eliminates the need for expensive contractors and specialized vacuum equipment. A typical DIY install takes 2-4 hours using basic tools — no special tools required. You will need to run the electrical wiring (a standard 20A or 30A circuit) and mount the indoor and outdoor units, but our step-by-step guides walk you through easy installation from start to finish. The advantage of DIY mini splits is that you save $3,000-$5,000 on installation cost. Browse our wall mount systems or linesets to get started.
How much money can I save with a DIY ductless mini split?
Zone Air customers typically save $3,000-$5,000 on total cost compared to contractor installation by handling the install themselves. Our Energy Star rated heat pump systems can also reduce annual energy costs compared to traditional HVAC systems thanks to up to 24 SEER2 inverter-driven efficiency. Between DIY mini split install savings and lower energy costs, many homeowners see significant savings over the first several years. Visit our FAQ page for more details on savings.
What size mini split do I need?
Mini-split sizing depends on room square footage, insulation quality, ceiling height, and climate zone. As a general guide: a single zone 9,000 BTU mini split covers up to 350 sq ft, 12,000 BTU covers 350-550 sq ft, and 18,000 BTU covers 550-1,000 sq ft. For larger spaces or multiple rooms, consider a dual zone or multi zone system with multiple air handlers. For the most accurate sizing, use a Manual J load calculation to determine the right cooling and heating capacity for your space.
How efficient are Zone Air mini split heat pumps?
Zone Air mini split heat pump systems achieve up to 24 SEER2 efficiency. Our Energy Star rated ductless mini split heat pumps use inverter technology for compressor speed control to reduce energy consumption compared to traditional HVAC systems. The heat pump works by transferring heat between indoor and outdoor units rather than generating it. In cooling mode, the system works as an air conditioner. In heating mode, including hyper heat mode, our cold climate heat pump units heat your space down to -13°F.
What warranty does Zone Air offer on mini split systems?
All Zone Air ductless mini split heat pumps come with a comprehensive 5-year warranty on parts and 5-year warranty on the compressor. We also offer a 45-day satisfaction guarantee so you can try your mini split heat pump system risk-free. With proper maintenance — including checking refrigerant levels and cleaning filters — your system will last 15-20 years. Free technical support is available via phone, email, and chat to help with installation questions or troubleshooting. See our FAQ page or browse wall mount systems to learn more.
How does Zone Air compare to other DIY mini split brands?
Zone Air DIY mini split systems feature up to 24 SEER2 efficiency, cold climate heat pump capability down to -13°F, and R454b eco-friendly refrigerant. Zone Air systems are priced competitively while including pre-charged linesets, a WiFi control module, and a full 5-year warranty. Choose from wall mount, ceiling cassette, and concealed ducted indoor unit styles. The combination of high efficiency, cold climate performance, and included accessories offers strong overall value.
What is the difference between single zone and multi zone mini splits?
A single zone mini-split system has one outdoor unit connected to one indoor unit — ideal for heating and cooling a single room or space up to 1,000 sq ft. A multi zone mini split heat pump system connects one outdoor unit to multiple indoor air handling units, allowing independent temperature control in multiple rooms. Consider a dual zone bundle for two-room setups. Multi zone systems are ideal for larger homes or when you want to heat and cool multiple rooms without existing ductwork.
