Verified reviews from Zone Air customers who bought this accessory.
The performance has been impressive from the start. It cools quickly, runs quietly, and feels like a quality setup.
Even when it is really hot outside, this keeps up well. I have not felt like it was struggling.
The heat works better than I expected. It takes the chill out of the room quickly, especially in the morning.
I like that I can use it for both cooling and heat. It has made the room comfortable in more than just one season.
I expected the install to be the hard part, but it really was not bad. Once I had it mounted and connected, everything worked like it should.
I needed something that would not keep me up at night, and this has been great. 3 stars because the app is only okay.
A Full 25 Ft of Mini-Split Reach — No Vacuum Pump, No Gauges, No HVAC Tech
The Zone Air quick-connect pre-charged mini split line-set is a full 25 ft lineset that lets you place the outdoor condenser farther from the indoor head — a 25 ft run in place of the standard 16 ft. It ships factory-sealed with R454B refrigerant already inside, so the circuit stays closed from the warehouse to your wall. You thread the brass quick-connect couplings by hand, torque them to spec, and the line is charged and ready — no vacuum pump, no manifold gauges, and no EPA Section 608 license required.
It is sized for Zone Air 9,000 and 12,000 BTU systems and uses professional-grade copper tubing with UV-resistant insulation rated for exposed outdoor runs. Installing an 18K BTU system? Use the larger-diameter 18K line-set instead, which is matched to the higher refrigerant flow of that unit.
Why You'll Love It
- A Full 25 Ft of Reach — Gives your installation a 25 ft run instead of the standard 16 ft, so the outdoor unit can sit around a corner, across a patio, or on the far side of a wall without compromising performance.
- No Vacuum Pump or EPA License — The line-set is pre-charged with R454B and sealed with quick-connect fittings. There is no refrigerant to handle and no Section 608 certification to worry about — the same DIY-friendly approach as every Zone Air system.
- Professional-Grade Copper — UV-resistant insulation and quality copper tubing stand up to sun and weather on outdoor runs, with flare connections engineered for a leak-free seal.
- Universal Quick-Connect Fit — Designed to match Zone Air 9K and 12K quick-connect ports, so it drops into your install with no adapters or special tools.
What Makes It Different
Most longer line-sets still require you to flare fittings, pull a vacuum, and recharge the system — work that needs an HVAC tech and defeats the purpose of a DIY mini split.
- Pre-Charged and Factory-Sealed — The refrigerant is already inside and the circuit stays closed, so you skip the vacuum and recharge steps entirely.
- Hand-Tight Quick-Connect — Brass couplings seat by hand and torque to spec — connect, check the joints with soapy water, and you are done.
How It Works
- Route the Line-Set — Run the pre-charged line-set through your wall penetration between the indoor head and the outdoor condenser, keeping bends gentle to protect the tubing.
- Connect and Check — Hand-thread the quick-connect couplings, torque to spec, and test each joint with soapy water before powering the system on.
Who It's For
This 25 ft lineset is for:
- DIY installers whose outdoor unit needs to sit more than 16 ft from the indoor head
- Garage, workshop, and addition installs where the condenser mounts around a corner or across a wall
- Zone Air 9K and 12K owners who want extra routing flexibility without hiring a technician
