SALT LAKE CITY, UTAH – FEBRUARY 9, 2026 – Zone Air today announced the launch of the Zone Air DIY Series, a new kind of mini split built for homeowners who want a DIY mini split system that is energy efficient, easy DIY, and built to save. The DIY Series brings DIY mini splits to modern house upgrades by letting a homeowner install a mini split on a wall, in a room, and expand across a home over time. Compared with traditional HVAC systems, the DIY Series delivers heating and cooling without existing ductwork, helping reduce overall cost, improve efficiency, and increase control.
The DIY Series Mini Split System, Explained
A DIY mini split consists of indoor and outdoor units, refrigerant lines, a line set, and clear installation guidance. The indoor and outdoor units work together as a heat pump system: an outdoor unit manages transferring heat by adjusting compressor speed, while indoor air handling units deliver conditioned air to the room. Each inside option uses an air handler; each air handler moves indoor air through a coil and fan for quiet comfort. Because the air handler is central to the system, Zone Air includes air handler setup checks, air handler filter guidance, air handler airflow notes, and air handler service support tips for proper maintenance.
The DIY Series is Built For DIY Install
Zone Air built the DIY Series for DIY install from start to finish: DIY steps, DIY tools lists, and a DIY plan that reduces guesswork. The installation path is simple: choose the room, select the wall location, mount the indoor head, route the line set, connect refrigerant lines, complete electrical wiring per code, and start the system. This is easy DIY because the guide breaks installation into short checkpoints, with photos and clear labels. For homeowners who want a faster install, the DIY Series supports easy installation practices that reduce rework and help save time.
Line Set Details, Range, and Wall Routing
Each kit includes guidance for line set length, because line set length typically ranges based on the wall-to-wall path and outdoor placement. The DIY Series also explains how to protect the tubing, how to manage space behind the indoor head, and how to confirm service support. Clear line routing helps preserve efficiency, reduce potential damage, and maintain warranty terms.
Startup Charge Checks to Protect Performance
To protect long-term performance, Zone Air includes a startup checklist for checking refrigerant levels at first power-on. This process helps confirm the refrigerant lines are sealed, reduces potential damage risk, and supports warranty documentation.
Heating, Cooling, and Hyper Heat Comfort
In cooling mode, the mini split system works like an air conditioner, acting as a whole-home air conditioner for zoned spaces, and provides steady cooling for the room. In heating mode, the heat pump efficiently heat by moving heat, and the variable compressor speed helps hold stable temperature. For colder climates, the DIY Series includes Hyper Heat performance so the heat output remains strong when temperatures fall. Hyper Heat capability, paired with precise control, can help save energy and keep in-home comfort consistent.
Control that Scales by Room and by House
Each mini split includes control options for temperature, fan, and schedules. Control can be set per room, and multi zone control can cover many rooms with independent zone settings. With better control, a homeowner can plan comfort, reduce cost, and save energy by limiting heating and cooling to occupied space. This advantage is especially useful in larger homes where comfort needs vary by room.
SIZING: SQ FT, Seer Rating, and Example Configurations
Zone-Air.com helps customers shop by sq ft and compare seer rating. Shoppers can filter by sq ft, review sq ft guidance, and match sq ft needs to system capacity. A single zone mini split can serve one room, while a multi zone mini split can serve more than one room in a home. As an example, a homeowner might install a single zone mini split for a bedroom and later add a second single zone mini split for a living room, improving comfort while keeping total cost manageable. The site explains how seer rating affects efficiency and energy use, so homeowners can save on long-term cost and save on monthly cost.
OPTIONS: Wall Mount OR Ceiling Cassette
The DIY Series supports wall-mounted indoor options and ceiling cassette options. Ceiling cassette models make it easier to serve bigger areas and keep wall space open. Zone Air offers ceiling cassette choices across the DIY Series, and the installation guide includes ceiling cassette placement notes, ceiling cassette drain guidance, ceiling cassette airflow tips, and ceiling cassette maintenance reminders. For multi zone layouts, ceiling cassette units can pair with wall units to serve a home with flexible in-home design. Ceiling cassette flexibility is a key advantage for owners who want to save wall space.
What’s in the Box?
Every DIY Series kit includes indoor and outdoor units, a pre charged line set, mounting hardware for wall installation, a DIY tools guide (no special tools required for the standard connection), and a step-by-step setup manual. Each kit also includes air handler notes for setup, air handler filter schedules, air handler airflow checks, and air handler troubleshooting steps to support proper maintenance and help protect warranty coverage.
Warranty and Support
Zone Air backs the DIY Series with a warranty built for DIY installation. Warranty registration includes an installation checklist and photo uploads. Warranty support helps customers confirm installation steps, verify air handler setup, and document the startup checklist. Optional warranty add-ons are available at purchase. The goal is clear: protect efficiency, protect the system, and help homeowners save.
DIY Mini Splits VS Traditional HVAC Systems
Traditional HVAC systems can require duct changes, and existing ductwork limitations can add cost. DIY mini splits avoid ductwork and bring an advantage in control, space use, and expansion. Another advantage is easy installation for a room-by-room approach. A third advantage is flexibility: add units later for larger spaces or larger homes without replacing the whole system.

DIY Mini Splits Product Summary (DIY SERIES)
The DIY Series focuses on DIY mini splits that homeowners can install as a mini split solution for any room. These DIY mini splits are built so a DIY customer can install a mini split, install the mini split system correctly, and save with a system that is energy efficient. Each DIY mini split system uses a heat pump, and each heat pump can deliver heat in heating mode and cooling in cooling mode. Because the system is ductless mini by design, the system does not require existing ductwork, and the system can scale to multiple rooms with more units.
Installation and Tools at a Glance
For DIY install, the installation guide repeats the install steps in three ways: quick install, standard install, and guided install. The installation checklist calls out the tools you need, notes that special tools are not required for the standard connection, and explains when optional tools may help. Most homeowners can install with common tools, follow the installation steps, and complete installation in a weekend.
Key Specs for DIY Mini Splits
These DIY mini splits include ductless mini comfort and a mini split for a small room, a mini split for a mid-size room, and a mini split option for larger spaces. Each mini split can be ordered as single zone, and the single zone lineup includes multiple units; available units can be matched by capacity, and these units are packaged as complete units for DIY buyers. These units ship as matched units, and replacement units are available; accessory units and upgrade units can be purchased. Shoppers can compare sq ft guidance by room: sq ft estimates, sq ft ranges, and sq ft examples. Each kit includes a pre charged lineset option and a pre charged accessory pack; pre charged components help simplify DIY install. For DIY install planning, the guide repeats DIY install checkpoints for wall setup, wiring, and startup. This makes easy DIY even easier, so easy DIY homeowners can follow easy DIY steps.
Indoor Unit Note
The indoor unit in the DIY Series pairs with the outdoor unit as part of the mini split system.
Heat and Cooling Notes for Homeowners
In heating mode, the heat pump moves heat efficiently, and the system can maintain heat output with Hyper Heat support. In cooling mode, the system delivers cooling like an air conditioner, and the mini split can hold temperature steady. If you want more heat, the control can raise temperature; if you want less heat, the control can lower temperature. This heat-and-cooling behavior helps the system save energy, save cost, and save comfort in each room.
