Aircond Installation Checklist for Malaysian Homeowners
By JBCoolCare – jbcoolcare.com
Installing a new air conditioner should be simple—but in reality, Malaysian homeowners often overlook important details that affect cooling performance, energy efficiency, safety, and long-term reliability. A proper installation can make your aircond last 10 years or more, while a rushed or poorly planned setup can lead to constant water leaks, gas leakage, electrical issues, and expensive repairs.
To help you avoid these problems, we’ve created the ultimate Aircond Installation Checklist that every Malaysian homeowner should go through before booking an installer. Whether you live in a landed house, condo, apartment, or shop lot, this checklist ensures you’re fully prepared for a smooth and worry-free installation.
1. Choose the Right HP (Horsepower) for Your Room Size
Before buying an aircond, make sure you choose the correct HP:
| Room Size | Recommended HP |
|---|---|
| 80–120 sq ft | 1.0 HP |
| 120–180 sq ft | 1.5 HP |
| 180–250 sq ft | 2.0 HP |
| 250–300 sq ft | 2.5 HP |
Choosing a smaller HP than needed results in weak cooling and high electricity use. Too large, and you waste money.
2. Check If Your Home Has a Dedicated Aircond Power Point
A proper aircond installation requires a dedicated electrical point. Ask yourself:
- Is there an existing aircond power socket?
- Does the DB box support the new load?
- Do you need rewiring?
In Malaysia, Suruhanjaya Tenaga (ST) requires wiring to be done by a certified wireman. Don’t DIY electrical work—it’s unsafe and may void insurance claims.
3. Decide on the Indoor Unit Placement
Your indoor unit’s position affects cooling efficiency. Choose a location that:
- Has no direct sunlight
- Avoids blowing cold air directly onto your bed or sofa
- Allows short piping distance
- Keeps wiring routes clean
- Avoids beams or structural obstacles
A good installer like JBCoolCare will assess the room and recommend the best placement.
4. Plan the Outdoor Unit Location Carefully
The outdoor compressor needs:
- A stable bracket
- Proper ventilation
- Protection from direct sunlight
- No blockage
- No interference with neighbours
- Safe distance from ground (for landed homes)
For condos, ensure the location follows building rules.
5. Check Condo or Building Management Regulations
If you live in a high-rise property, check:
- Approved installation hours
- Approved aircond locations (AC ledge, balcony, kitchen area)
- Permitted piping routes
- Contractor approval requirements
- Safety gear requirements
Many condos do not allow DIY installation and require certified, insured technicians.
6. Measure Piping Distance (This Affects Cost!)
Standard installation includes 8–10 feet of piping. Extra piping costs between RM20–RM28 per foot.
Before installation, check:
- How far is the indoor unit from the outdoor unit?
- Will the piping be concealed or exposed?
- Is additional trunking required?
Knowing the distance prevents surprise charges.
7. Confirm the Type and Quality of Copper Piping
Not all copper pipes are the same. Cheap, thin copper often leaks.
Your installer should use:
- Grade-A copper piping
- Proper insulation
- High-quality drain hose
- UV-resistant trunking
JBCoolCare uses premium copper to ensure long-term durability and prevent gas leaks.
8. Ensure Vacuuming Is Included (Never Skip This!)
Vacuuming removes moisture and air inside the copper pipes. It is the most important installation step.
A professional installer will vacuum the system for 15–20 minutes.
Skipping this leads to:
- Weak cooling
- Ice buildup
- Gas leakage
- Compressor damage
Always confirm vacuuming before booking.
9. Confirm Installation Includes Pressure Testing
After connecting the pipes, the technician should test the system using:
- A manifold gauge
- Pressure testing tools
- Leak detection spray
This ensures there are no leaks before releasing refrigerant.
10. Check Drainage Path to Avoid Water Leaks
Most homeowners only notice drainage problems weeks later.
Your checklist:
- Is the drain hose angled downward?
- Is it long enough?
- Will water flow freely outside?
- Does it avoid areas like walkways or neighbour property?
Proper drainage prevents indoor leaks and mould growth.
11. Ask About Bracket Condition (Replace if Rusty)
Outdoor bracket replacements cost RM40–RM80. If yours is rusty, unsafe, or unstable, replace it immediately to avoid accidents.
12. Ensure the Installer Is Using Proper Tools
Professional installers should bring:
- Vacuum pump
- Pressure gauge
- Copper cutter
- Level tools
- Insulation materials
- Electrical testing tools
Lack of equipment = unprofessional installation.
13. Request Transparent Pricing Before Installation
Ask for a full breakdown:
- Labour charges
- Piping cost
- Wiring
- Drilling
- Bracket replacement
- Concealed work
- Gas top-up (if needed)
A reputable company like JBCoolCare provides clear pricing with no hidden fees.
14. Check Warranty Coverage
Professional installation should include:
- Workmanship warranty
- Gas leakage warranty
- Installation defect coverage
Also confirm whether the brand warranty remains valid. DIY or uncertified installation may void the manufacturer warranty.
15. Post-Installation Testing
Before the technicians leave, ensure they:
- Test cooling performance
- Check airflow
- Inspect drainage
- Measure amperage
- Confirm thermostat accuracy
- Check noise levels
- Ensure no vibration
This final test guarantees your system works perfectly.
