For Malaysian homes: 60–65 BTU per square foot is the standard baseline. Add 10% for west-facing rooms, 10% for rooms above kitchen heat, and 600 BTU per additional occupant beyond 2 people. Our technicians calculate exact loads during the free survey — but this guide gets you 90% of the way there before we even arrive.
Project Timeline
Our streamlined multi-unit process — managed by a dedicated project team from quote to handover.
Day 1 — AM
WhatsApp us your floor plan or room list. Our senior technician visits your property. We assess every room, measure BTU requirements, inspect DB box capacity, plan pipe routes, and select outdoor unit locations. Free — no obligation.
Day 1 — PM
You receive an itemized quote: per-unit labour, total copper pipe length types, electrical work (if any), and total project cost. Once approved, we lock in your installation date — usually within 48 hours for landed homes.
Day 2 — Full Day
Our team arrives with all materials pre-staged. Units installed room by room in sequence. Drop sheets protect every area. Copper piping, vacuum (500 microns), electrical circuits, drain testing — every unit gets the full 7-step process.
Day 2 — End
All units run simultaneously for final testing. Cooling delta-T measured on every unit. Job cards signed room by room. Written 1-month workmanship warranty on all units. Remote controls paired. You walk through a fully cooled home.

Whole-House Installation FAQs
A 3-unit package starts from RM 597 for wall-mounted units (1.0–1.5 HP per room). 5-unit packages from RM 945. Each unit includes 7 ft copper pipe, insulation, electrical wire and drain pipe, vacuum pump commissioning, and 1-month workmanship warranty. Extra copper pipe beyond 7 ft is RM 17–27/ft. All pricing confirmed before any work starts.
Yes — our 5-unit package saves RM 50 compared to individual bookings, and includes a free DB box capacity assessment. For 10+ units, we provide custom volume pricing with dedicated project management. WhatsApp us with your unit count and property type for an exact quote.
Use our room-by-room BTU guide on this page. Small bedroom (100–150 sq ft): 1.0 HP. Master bedroom (150–250 sq ft): 1.0–1.5 HP. Living room (250–400 sq ft): 1.5–2.0 HP. Our technician confirms all sizes during the free site survey — no guesswork needed.
5 units typically complete in 1 full day (8 AM – 6 PM) with a dedicated 2–3 person team. 10+ units take 1–2 days. We pre-stage all materials the night before and work room-by-room in sequence. Landed homes are faster; condos may need an extra day for lift access windows.
Our technician checks your DB box during the free site survey. Most homes built after 2015 have 2–4 spare MCB slots. If you need additional slots or a higher-capacity main breaker, we quote the electrical work upfront. Typical panel upgrades range from RM 100–300 depending on scope.
Yes — this is actually very common for whole-house projects. Wall-mounted units in bedrooms (efficient, quieter) with a ceiling cassette in the open-plan living/dining area (better coverage, cleaner look). We install both types and coordinate the different mounting, drainage, and electrical requirements seamlessly.
Copper pipe beyond 7 ft is charged per foot: RM 17/ft (1.0–1.5 HP), RM 23/ft (2.0–2.5 HP), RM 27/ft (3.0 HP+). During the site survey, we measure the exact pipe length for every unit and include it in your quote. You approve all extras before work starts — no surprises.

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.
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.
Side-by-side comparison
Travel and setup are fixed costs on every visit, so batching units changes both the price and the day's schedule.
| What to compare | One unit per visit | All units in one visit |
|---|---|---|
| Cost per unit | Full published rate | Volume discount applies from 5 units |
| Time you need to be home | Repeated short visits | One longer block |
| Consistency of results | Different technicians on different days | Same team, same standard across the house |
| Best for | One unit with an urgent fault | Annual maintenance or a move-in |
In short: Fix the broken unit today if it is urgent, but put the rest of the house on one scheduled visit — the saving comes from the trip, not from cutting the work.
