You’ve finally decided to install a new air conditioner. Maybe your old unit has been struggling for years. Or perhaps you’re moving into a new place and want to get it right from day one. Whatever the reason, one question always comes first: What will this cost me, and what do I need to do?
I’m part of the Kedai Aircond team. We’ve done thousands of installations across Klang Valley since 2012. In this guide, I’ll walk you through the whole process – from picking the right unit to understanding every charge. No fluff, no hidden fees – just honest advice from real experience.
Whether you’re in a condo in Subang Jaya, a terrace in Shah Alam, a semi‑D in Petaling Jaya, or an office anywhere in Selangor, this guide is for you.

First Things First: 3 Decisions That Save You Money
Making the right choices before you book will prevent costly mistakes and ensure you get exactly what you need – without paying for extras you don’t.
1. Get the Horsepower Right for Your Room
This is the most common mistake. If you pick a unit that’s too small, it will run non‑stop trying to cool the room. That wears it out fast and makes your electricity bill soar. If you pick one that’s too big, it will turn on and off too often, waste power, and not remove humidity well. Use this quick guide:
| Room Size (sq ft) | Recommended HP | Inverter Price Est. | Notes |
|---|---|---|---|
| Up to 100 | 0.75 HP | RM 1,000–1,400 | Small bedroom, standard ceiling |
| 100–150 | 1.0 HP | RM 1,200–1,800 | Standard single bedroom |
| 150–250 | 1.5 HP | RM 1,400–2,200 | Master bedroom, study room |
| 250–350 | 2.0 HP | RM 2,000–3,000 | Living room, dining area |
| 350–500 | 2.5 HP | RM 2,500–3,800 | Large living room |
| 500–800 | 3.0 HP | RM 3,000–5,000 | Open‑plan hall, large office |
| 800–1,200 | 4.0–5.0 HP | RM 4,500–7,000+ | Commercial space |
These numbers are for rooms with normal ceilings (about 9‑10 ft). If your room gets strong afternoon sun, has high ceilings, or isn’t well insulated, go one size up.
2. Inverter or Non‑Inverter – Which Wins in 2026?
If you use the room more than 2 hours a day, an inverter unit is the smarter choice. Here’s why:
| Factor | Non‑Inverter | Inverter |
|---|---|---|
| How it runs | Full power on/off | Adjusts speed continuously |
| Installation labour | RM 250–320 | RM 280–420 |
| Unit price (1.5HP) | RM 1,000–1,400 | RM 1,400–2,200 |
| Monthly electricity | Higher – keeps switching on/off | 30–50% lower – runs gently most of the time |
| Noise level | Louder | Quieter |
| Best for | Rooms used less than 2 hours/day | Bedrooms & living rooms used daily |
In Malaysia’s climate, the extra money you pay for an inverter pays for itself in electricity savings within 12–18 months.
3. Which Brand Should You Choose?
Your brand choice affects both the price and how long the unit lasts. Here’s a quick look for 2026:
- Daikin – The most popular in Malaysia. Good efficiency, easy to find parts, and many service centres.
- Panasonic – Strong on energy savings and air purification; good for families.
- Mitsubishi Electric – Premium build, very quiet; ideal for bedrooms where noise matters.
- Midea / Acson – Solid budget options; reliable cooling without the high price.
- York – Affordable, but fewer inverter models; good for basic cooling needs.

How to Prepare for Installation Day – A Complete Checklist
Good preparation means the job gets done faster, cleaner, and with no last‑minute surprises. Run through this list before the technician arrives.
📋 Your Pre‑Installation Checklist
- Clear the area – Move furniture away from the indoor wall and the outdoor compressor spot.
- Pick your wall location – Have a preferred spot in mind; the technician will confirm if it’s suitable.
- Check the power source – You’ll need a dedicated 15‑amp socket within 1.5 metres. Older homes may need an electrician to add one.
- Measure your room – Length × width in sq ft to confirm the correct HP (use our table above).
- Decide outdoor unit placement – Ground level, wall bracket, or rooftop? This affects piping length and cost.
- Clear outdoor access – Make sure the area around the outdoor unit is free of obstacles.
- Have your unit details handy – If you bought the unit separately, keep the manual or box nearby.
- Keep kids and pets away during work – Safety first.
- Stay for the final test – Test the cooling, drainage, and remote with the technician before they leave.
The most overlooked item? The outdoor unit location. If you’re unsure, ask us when you book – we’ll advise based on your building layout.
Step‑by‑Step: What Happens During a Professional Installation
Knowing what to expect means you can follow along and make sure everything is done right. Here’s the typical process:
| Step | Stage | Time | What Happens |
|---|---|---|---|
| 1 | Site inspection | 5–15 min | Technician checks wall type, electrical supply, outdoor placement; final price confirmed. |
| 2 | Marking & drilling | 15–30 min | Indoor unit position marked; holes drilled for piping and drainage. |
| 3 | Mounting indoor unit | 20–30 min | Backplate fixed, unit levelled for proper drainage. |
| 4 | Outdoor unit placement | 15–25 min | Compressor secured on bracket or stand in a well‑ventilated spot. |
| 5 | Copper pipe & drainage run | 20–40 min | Pipes connected, insulation wrapped, drainage routed to outlet. |
| 6 | Electrical connection | 15–20 min | Wiring, isolator switch, and power connection. |
| 7 | Vacuum & gas charging | 20–30 min | Critical step: vacuum pump removes moisture, then refrigerant charged to spec. |
| 8 | Test & handover | 15–20 min | Unit tested, walkthrough, sign‑off. |
A standard wall‑mounted unit takes 2.5–4 hours. Ceiling cassette units or jobs with long pipe runs may take longer.
Why the vacuum step matters: Skipping it leaves moisture inside, which rusts the compressor from the inside and causes early failure. At Kedai Aircond, we never skip it – and we’re happy to show you while we work.

📖 Real‑Life Installation: A Subang Jaya Condo Story
Last month, we installed a 1.5HP Daikin inverter unit for a family in a Subang Jaya condo. The owner first got a quote from another company that didn’t include the vacuum pump step. We explained why it’s essential and gave a clear itemised quote. On installation day, the technician showed the owner the vacuum gauge and explained each step. Now the unit runs quietly, and the owner’s first month’s electricity bill dropped by RM 35 compared to their old non‑inverter unit. The extra RM 150 they paid for the inverter and proper installation will be paid back in less than 5 months of savings.
DIY vs Professional Installation: Why the Risk Is Not Worth It
We understand – saving a few hundred ringgit sounds good. But aircond installation is one of the few home jobs in Malaysia where DIY is genuinely not safe. Here’s why:
| Factor | DIY Installation | Professional Installation |
|---|---|---|
| Cost | Looks cheaper upfront | Transparent fixed quote – no surprises |
| Refrigerant handling | Illegal without CIDB certification | Fully legal, CIDB‑certified |
| Manufacturer warranty | Usually voided | Stays fully valid |
| Safety risk | Fire hazard, leaks | Proper wiring & gas charging |
| Drainage setup | Often wrong – leads to water leaks | Correctly angled for reliable flow |
| Vacuum pump step | Almost always skipped | Always performed |
| Workmanship warranty | None | 1‑month warranty included |
Under Malaysian law (Electricity Supply Act 1990 and CIDB regulations), handling refrigerant without a license is illegal. Beyond legal risks, improper wiring is a known cause of electrical fires in Malaysian homes. For a deeper dive, read the Complete Aircond Guide Malaysia 2026 from Home Care Tips Malaysia.
Keeping Your New Aircond Running Like New – Aftercare Tips
A well‑installed unit is just the start. What you do in the months after installation decides how long it lasts and how much it costs to run. In Malaysia’s heat and humidity, maintenance is not optional – it’s the difference between a unit that lasts 5 years and one that lasts 12.
Routine Servicing – Every 3–6 Months (RM 60–100)
Standard cleaning removes dust and debris from the filter and coils. In dusty areas like KL and Selangor, skipping this causes buildup that makes your unit work harder, cool less, and use more electricity. A RM 80 service every 5 months is far cheaper than the alternative.
Chemical Wash – Once a Year (RM 120–180)
A deep chemical wash reaches the buildup that standard servicing cannot – mould inside the coils, bacteria in the drainage system, and accumulated grime that reduces airflow. In Malaysian conditions, this is recommended every 12 months, or sooner if you notice musty smells or reduced cooling performance.
Our aircond chemical wash service covers what the process involves, how long it takes, and what it costs.
Watch for Early Warning Signs
Catch problems early, and an RM 100 repair prevents an RM 600 breakdown. The three most common issues after installation in Malaysian conditions are:
- Cooling performance drops after 6–12 months – Usually low refrigerant or dirty coils. Have a technician check gas pressure and clean coils.
- Water dripping from the indoor unit – Blocked drainage is the main culprit. Flush the drain line; if it recurs, a professional chemical wash may be needed.
- Unusual sounds from the compressor – May indicate low gas or an electrical issue. Don’t ignore grinding or buzzing.
If your unit is not cooling as well as it should, read our guide to why your aircond is not cold and how to fix it before calling for a repair – some causes have simple DIY fixes.
Frequently Asked Questions About Aircond Installation in Malaysia
How long does aircond installation take?
A standard wall‑mounted split unit takes 2.5 to 4 hours. Ceiling cassette units or complex jobs may take 4–6 hours. We’ll give you a time estimate before starting.
What’s included in a standard installation?
Indoor unit mounting, outdoor compressor placement, 6 ft copper piping, drainage setup, electrical connection to a nearby point, vacuum pump & gas charging, system test, and 1‑month workmanship warranty.
Is installation price separate from the unit price?
Usually yes. Always confirm whether you’re looking at labour only, labour + materials, or a full supply‑and‑install package.
Do I need to prepare anything before the technician arrives?
Yes – clear the indoor and outdoor areas, decide on locations, and ensure a power point is available. See our full checklist above.
Can I choose where the indoor and outdoor units go?
Absolutely. The indoor unit needs a clear wall, the outdoor unit needs ventilation. We’ll work with your preference and advise on the best placement.
What if extra work is needed not in the original quote?
We always stop, explain, and confirm any extra cost before proceeding. If a company adds charges without telling you, that’s a red flag.
Why must the installer be CIDB‑certified?
It’s a legal requirement for handling refrigerant and electrical work. An uncertified installer voids your warranty and creates safety risks. All Kedai Aircond technicians are fully certified.
Can I use my aircond immediately after installation?
Yes. After the vacuum and gas charging, and once the system test passes, your unit is ready to use right away.
What warranty do I get on the installation work?
We offer a 1‑month workmanship warranty. If any installation‑related issue arises within 30 days, we fix it at no charge.
Is it worth installing multiple units at once?
Yes – most companies, including us, apply a discount for second and third units installed in the same visit. Ask for a package price.
Final Thoughts
A well‑planned aircond installation in Malaysia 2026 is straightforward if you follow these steps: pick the right HP, choose an inverter for daily‑use rooms, get a written itemised quote, make sure the vacuum pump step is done, and use a CIDB‑certified installer.
Do these, and you’ll have a unit that runs efficiently, cools reliably, and lasts 10–15 years. Have questions? Our team is here to help – no pressure, no obligation.
