Professional Aircond Installation in Petaling Jaya
Installing a new aircond is not just about mounting a unit on the wall and connecting two pipes. A properly installed air conditioning system requires precise BTU calculation for your room size, correctly sized and routed copper piping, proper drainage pipe slope, adequate electrical wiring, and professional gas charging. Get any of these wrong, and your expensive new unit will underperform, consume excess electricity, or develop problems within months.
At PJ Kool Aircond Service, our senior technicians bring over 20 years of installation experience across every major brand -Daikin, Panasonic, York, Mitsubishi, Samsung, LG, and Carrier. Whether you are replacing an old unit, installing aircond in a new home, or fitting out a commercial space, we ensure your installation is done right the first time.

How We Determine the Right Aircond for Your Space
BTU Calculation and HP Rating
Choosing the correct HP rating is the single most important decision in aircond installation. An undersized unit will run constantly without adequately cooling the room. An oversized unit will short-cycle -turning on and off repeatedly -wasting electricity and wearing out the compressor prematurely.
Our site assessment includes precise BTU calculation based on:
- Room dimensions -length, width, and ceiling height
- Sun exposure -west-facing rooms and top-floor units need more cooling capacity
- Window area -large windows allow more heat gain
- Number of occupants -each person adds approximately 400 BTU of heat
- Heat-generating equipment -kitchens, server rooms, and equipment rooms require higher capacity
- Insulation quality -poorly insulated rooms or rooms with thin walls lose cooling faster
General HP Guide for Malaysian Homes
| Room Size | Recommended HP | Typical Room |
|---|---|---|
| Up to 150 sq ft | 1.0 HP | Small bedroom, study room |
| 150 – 250 sq ft | 1.5 HP | Master bedroom, small living room |
| 250 – 400 sq ft | 2.0 HP | Large bedroom, medium living room |
| 400 – 550 sq ft | 2.5 HP | Large living room, open-plan area |
| 550 – 750 sq ft | 3.0 HP | Very large room, small office |
These are guidelines -our on-site assessment provides exact recommendations for your specific situation. In Petaling Jaya’s tropical climate, we typically factor in an additional 10-15% capacity to account for the sustained heat and humidity.
Inverter vs Non-Inverter Technology
Modern inverter technology is one of the most significant advancements in air conditioning. Here is how the two types compare:
Inverter Aircond:
- Compressor adjusts speed continuously rather than cycling on/off
- Uses 30-50% less electricity compared to non-inverter
- Reaches set temperature faster
- Operates more quietly
- Higher upfront cost, but pays for itself in electricity savings within 2-3 years
Non-Inverter Aircond:
- Compressor runs at fixed speed, cycling on and off
- Lower purchase price
- Higher electricity consumption over time
- Suitable for rooms used infrequently (guest rooms, storage)
For bedrooms, living rooms, and offices used daily, we strongly recommend inverter models from brands like Daikin, Panasonic, or York. The electricity savings in Malaysia’s climate are substantial.
The Installation Process
Step 1: Free Site Assessment
We visit your home or office at no charge to assess the installation requirements. Our technician measures the room, inspects the proposed piping route from indoor to outdoor unit, checks electrical capacity, and identifies any challenges (concrete walls, long piping runs, limited outdoor space).
Step 2: Piping and Wiring Preparation
The route between indoor and outdoor units is prepared. This involves:
- Copper piping -sized correctly for the HP rating and refrigerant type (R32 or R410A)
- Armaflex insulation -wrapping all refrigerant pipes to prevent condensation and energy loss
- Trunking -neat PVC or metal trunking to conceal piping where it runs along walls
- Drainage pipe -routed with proper downward slope to prevent water accumulation
- Electrical wiring -dedicated circuit from the DB box to handle the unit’s power requirements
Step 3: Indoor Unit Installation
The wall-mounted unit or ceiling cassette is mounted on a steel bracket, levelled precisely, and connected to the piping, drainage, and electrical systems. For wall-mounted units, we core-drill through the wall for pipe passage and seal the hole with weatherproof putty.
Step 4: Outdoor Unit Installation
The outdoor compressor unit is positioned on a concrete pad, wall bracket, or compressor cage with proper clearance -at least 30cm on all sides for adequate airflow. We connect the refrigerant lines, charge the system with the correct amount of gas, and verify there are no leaks using electronic leak detection.

Step 5: Testing and Handover
After installation, we perform a comprehensive test:
- Cooling performance -verifying the outlet temperature reaches the expected range
- Drainage flow -confirming condensate drains properly without leaks
- Electrical safety -checking all connections are tight and properly insulated
- Remote control -testing all modes (cool, fan, dry, timer)
- Noise level -ensuring normal operation sound levels
We then walk you through the remote control functions, explain optimal temperature settings for Malaysian conditions (24-26°C), and recommend a maintenance schedule to keep your new unit performing at its best.
What Affects Installation Pricing
Unlike our fixed-price cleaning and chemical wash services, installation pricing is quote-based because costs vary significantly depending on the specific requirements:
| Factor | Impact on Cost |
|---|---|
| Piping length | Longer distance between indoor and outdoor units = more copper pipe and insulation |
| Trunking | Surface-mounted trunking adds material and labour costs |
| Wall material | Concrete walls require core drilling; brick/wood is simpler |
| Electrical work | If a new circuit breaker or dedicated wiring is needed from the DB box |
| Height and access | High ceilings or difficult-to-reach locations require additional equipment |
| Number of units | Multiple units in one visit are more cost-effective per unit |
Our free site assessment ensures you receive an accurate quote with no hidden surprises. We explain every cost component so you know exactly what you are paying for.
