Pressure tested
The pre-charged valve assembly is rated to handle 921 PSI and checked for leaks.
Ductless Mini-Splits
DIY 5th Generation
A single-zone mini-split a homeowner can install with a pre-charged line set. How Much? can also install it for you.

- The line set arrives charged, so the install does not start with a vacuum pump.
- Andy can sell the equipment, install it, or both.
- Style
- Single-zone ductless
- Refrigerant
- R-454B
- Line set
- Pre-charged quick connect
How it goes in
The line set shows up already charged
The indoor head and the outdoor unit connect with a pre-charged line set. You are not pulling a vacuum or weighing in refrigerant on the driveway. How Much? can still do the whole install if you would rather not.
- 01Set the headMount the indoor unit on a solid wall, high enough to throw air across the room.
- 02Run the lineThe line set is already charged. The fittings close the circuit without a vacuum pump.
- 03Power itOnce it is wired and the outdoor unit is set, the system is ready to heat and cool that zone.
The facts that matter
Listed equipment
The valve control is certified under UL 207 and CSA C22.2 No. 140.3. Intertek file 5029931.
R-454B
This generation uses R-454B, the refrigerant these current DIY systems are built around.
No vacuum step
The charge is already in the line set, so the install skips the vacuum and the gauge set.
Why this one
Heat and cool one room without opening the walls
This is the system for a room the rest of the house never quite gets right. A bedroom that bakes, a garage you actually sit in, an addition with no duct. The line set shows up already charged, so the hard part of a mini-split is already done.
Warm when the morning is not
It keeps heating when it is down to -13 F outside, and it keeps cooling when the yard hits 122 F. You feel that on the first cold night and the first week of September, not on a spec sheet.
The temperature where you are sitting
One head, one room, one setting. You are not bargaining with a hallway thermostat that thinks the whole house is the living room. Five sizes run from a bedroom up to about 1,550 square feet. If the room is bigger than that, or you need a second head, this is the wrong box and we will say so.
Quiet enough to sleep next to
The indoor unit is what you live with. It should disappear once the lights are off. After a power blink it comes back on the settings you left, including the louver, instead of waiting for someone to reprogram it in the dark.
Questions
What changed from the previous DIY generation?
This generation uses R-454B. Earlier DIY systems used R-410A.
Does the box include the wire between the indoor and outdoor units?
A bundled system includes the communication wire so the two pieces can talk to each other.
Can I do this myself?
The line set is made for a homeowner install. How Much? will also mount it, run it, and stand behind the work if you want that.
How many rooms can one outdoor unit cover?
A single-zone system covers one space. Multi-zone condensers in this family support anywhere from 2 to 6 indoor heads, depending on the model.
