Hitachi PAS-3.0UFASNQ1

The outdoor unit of a 7.07 kW single split system, rated 4 green ticks. Costs about $73 a month to run — here is how that compares with every other system its size on Singapore's NEA register.

Is the PAS-3.0UFASNQ1 expensive to run?

Yes, it's one of the pricier ones to run at this size. Of the 17 systems on Singapore's register around this size, 13 cost less to run.

About $875 a year

17 systems, all brands

That is about $13 a month more than the cheapest system its size, or roughly $1,580 over ten years — before you weigh purchase price, which often runs the other way.

It is not an inefficient unit, though. It sits at the larger end of its size group, so it works harder for the same rating. On efficiency alone it ranks 13 of 17 — middle of the pack.

Cheaper systems the same size

Systems around the same size that cost less to run, closest in size first. Cheaper to run is not the same as the better buy — purchase price, indoor units, and how well it is installed all sit outside these figures.

Looking at the PAS-3.0UFASNQ1 for your home?

This is the outdoor half of a pair. The indoor unit is the half you live with, and it should be named before anything is agreed.

What to pin down before you commit

  • The paired indoor model number — the unit that mounts in the room
  • Whether the capacity suits that room, and how that was decided
  • What happens to the existing piping, drainage and bracket
  • Whether the old unit is being removed and disposed of

Figures are NEA energy-label records checked 17 Sept 2026, priced at the label's 27¢/kWh assumption. Your own bill depends on how you actually use it.

Hitachi PAS-3.0UFASNQ1 questions

Is the Hitachi PAS-3.0UFASNQ1 the right size for my room?
The NEA register lists it at 7.07 kW of cooling capacity. Match that against the room's size and heat load rather than assuming one capacity suits every room, and have the installer confirm it before the unit is chosen.
What does the 4-tick rating on the PAS-3.0UFASNQ1 mean?
The NEA energy label rates it 4 of 5 green ticks, in the upper band for tested efficiency. Ticks describe energy use under the label test, not cooling strength, so compare it with units of the same size.
Is the PAS-3.0UFASNQ1 a single-split or multi-split system?
It is a single-split: one outdoor unit paired with one indoor unit, listed at 7.07 kW on the register. That makes it a one-room system, and the quote should name the paired indoor model.
Is the Hitachi PAS-3.0UFASNQ1 still on the NEA register?
Yes. Its registration runs to 27 June 2027, more than four months after the 17 September 2026 snapshot this page is built from.
How efficient is the PAS-3.0UFASNQ1 at part load?
NEA records a part-load COP of 5.77 for the PAS-3.0UFASNQ1. Part-load efficiency describes how it performs when it is not running flat out, which is how it runs most of the time in a home.
