Window Unit Installation Specialists
Simple, Affordable Cooling
Window airconds are a practical choice for rented rooms, older apartments, and budget-conscious households. Everything is contained in one unit — no separate indoor/outdoor piping, no vacuum pump, and no complex bracket work. We mount the unit securely, seal the opening, and wire it to a dedicated circuit.

Definitions
Short, plain-language definitions of the terms used above — written by the technicians who do the work, not copied from a manufacturer brochure.
The outdoor unit holds the compressor, the condenser coil and the fan that blows heat away from the coil. It can only reject heat if air moves freely through the fins, so a coil packed with dust, a unit boxed into a tight service yard, or a hot wall right behind it all raise running pressure and electricity use.
Leave at least 30 cm of clear air behind the condenser and never enclose it in a sealed cabinet or grille box.
The isolator is the local switch that cuts power to one aircond so a technician can work on it safely; the MCB is the circuit breaker in the distribution board that protects that circuit against overload and short circuit. Each unit should sit on a correctly rated circuit — sharing a lighting circuit or running off an extension lead is both a nuisance-trip and a fire risk.
Repeated tripping is a wiring or capacity problem to investigate, never something to fix by resetting the breaker harder.
Every cooling coil pulls litres of water out of humid Malaysian air each day. That water collects in the drain tray and leaves through a gravity drain pipe. Slime from the coil, dust and insects gradually narrow the pipe until water backs up over the tray lip and drips down your wall. Nine out of ten indoor water leaks are a blocked drain, not a refrigerant fault.
Before booking a repair, check whether the outdoor end of the drain pipe is still dripping while the unit runs — no drip means a blockage.
Side-by-side comparison
Window units still make sense in older walk-ups and rentals where no outdoor bracket is allowed.
| What to compare | Window unit | Split system |
|---|---|---|
| Installation | Single opening, no copper run | Indoor + outdoor, piping and drainage route |
| Noise in the room | Compressor sits in the room opening | Compressor is outside |
| Efficiency options | Limited, mostly fixed speed | Full inverter range |
| Published chemical wash | RM 130 | RM 120 |
In short: If the building allows an outdoor unit, split wins on noise and efficiency. If it does not, a window unit properly sealed into the opening is still a valid answer.
Frequently Asked Questions
Window unit installation starts from RM 199 for 1.0–1.5 HP and RM 249 for 2.0 HP. Price includes window frame mounting, weather sealing, electrical wiring, and 1-month workmanship warranty.
Window unit installation is quick — usually 2–3 hours. It doesn't require copper piping or vacuum pump work, so it's ideal for same-day service.
No — window units are self-contained. The compressor and condenser are built into the same chassis that sits in your window. Only a small rear section extends outside.
Window units are usually only allowed in older apartments or specific building designs. Most modern condos require split units. We can advise whether a window unit is suitable for your property.
