How it goes in
A smaller DIY system, same charged line set
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
A smaller system for a room that just needs its own air
Select is the straightforward single-zone kit. Same idea as the 5th generation: a charged line set, one head, one outdoor unit. It is the one we point people to when the room is simple and they do not need the longer feature list.
That one room, finally
A guest room over the garage, a home office that was an afterthought, a sunroom the central system never reaches. Select heats and cools that space on its own, so you stop opening windows and running a space heater in the same afternoon.
You can hang it, or we can
The line set is already charged. A careful homeowner can mount the head, run the line, and power it. If you would rather not be on a ladder with a torque wrench, How Much? does the same install and stands behind it. Either way you are not paying for a vacuum pump and a refrigerant scale on day one.
Leave the rest of the house alone
The ducts, the furnace, and the thermostat stay as they are. You are adding a zone, not replacing the system that already works for the rooms that were built with it.
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.
