Looking at the PWA-3300W for your home?

This is the whole appliance. The opening it sits in decides most of what can be fitted.

What to pin down before you commit

  • The opening dimensions, measured — not assumed from the old unit
  • Whether the existing bracket and surround are being reused
  • How the drainage is routed, and where the water goes
  • Removal and disposal of the unit coming out

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. Already have one installed and seeing a fault code? Look it up here, or Compare every registered model. More on PASECO systems, or read up on Common aircon problems.

PASECO PWA-3300W questions

Is the PASECO PWA-3300W the right size for my room?
The NEA register lists it at 1.31 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 2-tick rating on the PWA-3300W mean?
The NEA energy label rates it 2 of 5 green ticks. That sits in the lower part of the scale, so higher-rated units of the same size use less energy under the label test — check the same-size comparisons on this page.
What kind of aircon is the PWA-3300W?
It is a casement unit, listed at 1.31 kW on the register, a single box mounted in a wall opening rather than a split pair. The opening dimensions and drainage route decide the installation.
Is the PASECO PWA-3300W still on the NEA register?
Yes. Its registration runs to 19 November 2029, more than four months after the 17 September 2026 snapshot this page is built from.
How efficient is the PWA-3300W at part load?
The register does not list a part-load COP for the PASECO PWA-3300W, but it records a full-load COP of 3.81. That figure only describes efficiency when the unit runs at full output.
