1.5HP Wall-Mounted Installation Specialists
Why 1.5HP Is the Most Versatile Choice
1.5HP is the sweet spot for most Malaysian homes. It comfortably cools master bedrooms up to 180 sq ft and small living rooms, even with afternoon sun. If you're unsure between 1HP and 2HP, 1.5HP is usually the right answer for bedrooms and compact living spaces across KL & Selangor.

Definitions
Short, plain-language definitions of the terms used above — written by the technicians who do the work, not copied from a manufacturer brochure.
HP is the informal Malaysian shorthand for cooling capacity, carried over from compressor horsepower. In practice 1.0 HP ≈ 9,000 BTU/h, 1.5 HP ≈ 12,000 BTU/h, 2.0 HP ≈ 18,000 BTU/h and 2.5 HP ≈ 24,000 BTU/h. Service, chemical wash and installation prices are all quoted against these bands, which is why the technician asks for HP before quoting.
HP is printed on the indoor unit's side label and on the outdoor nameplate — check there rather than guessing from room size.
BTU per hour measures how much heat a unit removes from a room in an hour. A 1.0 HP wall unit is roughly 9,000 BTU/h and a 1.5 HP is roughly 12,000 BTU/h. Room area sets the baseline, then you add capacity for west-facing windows, a top-floor ceiling, high occupancy or kitchen heat.
Oversizing is a real mistake: an over-large unit hits temperature fast, short-cycles, and leaves the room cold but damp.
A flare joint is the cone-shaped end formed on soft copper tubing so it can seal metal-to-metal against the unit's service valve under a flare nut. The cone must be cut square, deburred and torqued to spec. Over-tightening cracks it, under-tightening leaks slowly — which is why most refrigerant loss on a young system is found at a flare, not in the coil.
A soap-bubble test on every flare after commissioning takes two minutes and catches the leak before it costs you a top-up.
Side-by-side comparison
Floor area is the starting point; heat load from sun, ceiling height and occupancy moves the answer up a size.
| What to compare | 1.0 HP (≈ 9,000 BTU/h) | 1.5 HP (≈ 12,000 BTU/h) |
|---|---|---|
| Typical room | Small bedroom up to about 120 sq ft | Master bedroom or small hall, 120–180 sq ft |
| Afternoon sun on the wall | Struggles — size up | Copes |
| If oversized | Rarely a problem | Short-cycles, room cold but clammy |
| Published installation price | RM 199 | RM 199 |
In short: Measure the room and count the west-facing glass before choosing; the two sizes cost the same to install, so pick on heat load, not on price.
