The Customer's Situation

Encik Danish Irfan and his wife Puan Ain had just received the keys to their first home — a 2-bedroom condo in Setia Alam. The unit came bare — no aircond, no water heater, basic lighting only. As new homeowners on a budget, they needed to be smart about every purchase.

They'd done their homework on inverter vs non-inverter aircond and decided on inverter for the long-term TNB savings. After comparing brands and prices, they settled on Midea's Xtreme Inverter series — offering solid specifications at a more affordable price point than Daikin or Panasonic.

Their requirements were straightforward:

  • Master bedroom (~180 sq ft, west-facing): 1.5HP inverter
  • Second bedroom (~120 sq ft, north-facing): 1.0HP inverter
  • Living room: Skip for now, use a standing fan (budget constraints)

They contacted us for a supply-and-install package, as the condo had no existing aircond infrastructure at all — no pipes, no brackets, no drainage, no dedicated electrical circuits.

Installation Challenges

  • Brand new unit with zero existing aircond infrastructure
  • Condo management requires pre-approval for outdoor unit bracket installation on building exterior
  • Pipe routing needed to go through concrete wall and along the exterior — 8 metres for master, 5 metres for second bedroom
  • No dedicated MCB slots available in distribution board — needed to add a mini DB
  • West-facing master bedroom with large window — confirmed 1.5HP was minimum requirement

Pre-Installation: Site Survey and Planning

Before any work started, our team leader Syahir visited the condo for a site survey. This step is crucial for new installations — especially in condos where there are building management rules to follow.

During the survey, Syahir:

  • Measured both bedrooms and confirmed HP sizing (1.5HP and 1.0HP — spot on with Encik Danish's research)
  • Identified the optimal indoor unit mounting positions for each room
  • Planned the pipe routing — shortest and neatest path from indoor to outdoor units
  • Checked the outdoor unit location designated by the condo management (all units in this development go on the designated AC ledge on each floor)
  • Assessed the electrical situation — the existing DB had 2 spare slots, but both were 10A, insufficient for aircond. Solution: install a 4-way mini DB beside the main DB.
  • Helped Encik Danish submit the installation application to building management

Installation Day

Once management approval came through (took about a week), we scheduled the installation. Syahir arrived with his assistant Zul at 8am sharp.

Work Completed

  • Installed 4-way mini distribution board with 2x 20A MCBs (one per aircond unit)
  • Ran 2.5mm² electrical cables from new mini DB to each bedroom
  • Core-drilled 3-inch holes through concrete wall for both pipe runs
  • Installed indoor unit mounting plates with level alignment and wall anchors rated for concrete
  • Mounted both indoor units and connected all electrical, communication, and drain lines
  • Ran copper piping (1/4" + 3/8" for 1.5HP, 1/4" + 3/8" for 1.0HP) with proper insulation
  • Installed outdoor units on the designated AC ledge with rubber isolation pads
  • Sealed wall penetrations with fire-rated sealant (condo requirement)
  • Installed PVC trunking to conceal piping runs along bedroom walls — neat finish
  • Nitrogen pressure test on both systems — held at 400 PSI for 30 minutes each
  • Triple vacuum evacuation on both systems
  • Released factory-charged R32 refrigerant and verified with manifold gauges
  • Full commissioning test on both units — cooling, drainage, electrical, noise

PVC Trunking: The Neat Finish

For a brand new condo, Encik Danish and Puan Ain wanted the installation to look clean and professional — no exposed copper pipes running along the walls. Syahir used white PVC trunking to conceal all pipe runs inside the bedrooms. The trunking runs along the wall-ceiling junction, barely noticeable once painted to match the wall colour (which the Lims planned to do themselves later).

They selected a Midea inverter unit, which offers excellent value in the mid-range segment. See how Midea compares against other manufacturers in our 2026 brand comparison.

This is a small detail but makes a big difference in the overall look. Many budget installers just tape the pipes to the wall with PVC tape — functional but ugly. Proper trunking costs a bit more (RM80-120 per room) but looks much better, especially in a new home.

Results

Both units were commissioned by 2pm. Performance test results:

Master Bedroom (Midea Xtreme 1.5HP Inverter)

  • Air outlet temperature: 11°C
  • Room cooling: 33°C to 24°C in 15 minutes
  • Noise level: Very quiet — Puan Ain said she couldn't hear it at all on low fan
  • Despite west-facing window, the room cooled and maintained temperature comfortably

Second Bedroom (Midea Xtreme 1.0HP Inverter)

  • Air outlet temperature: 11°C
  • Room cooling: 32°C to 24°C in 10 minutes (smaller room, no sun exposure)
  • Perfect for the room size — not oversized, not undersized

Pricing Breakdown

  • Midea MSXS-10CRDN8 1.0HP Inverter (unit): RM1,200
  • Midea MSXS-13CRDN8 1.5HP Inverter (unit): RM1,600
  • Installation materials (copper pipes, trunking, brackets, drain, sealant): RM600
  • Electrical work (mini DB, MCBs, wiring): RM350
  • Installation labour (2 units): RM450
  • Total: RM4,200

First Month's TNB Impact

Encik Danish messaged us a month later to share his first TNB bill since installing the airconds. Running both units for about 7-8 hours per night (on top of normal household electricity for fridge, washing machine, lights, etc.), his total bill was RM185. He estimated the aircond portion was about RM95-100 — right in line with what we'd projected for two inverter units.

For comparison, his colleague at work has a similar-sized condo with two non-inverter units and pays about RM140-150 just for the aircond portion. That's RM40-50/month more — or roughly RM500-600 per year. The inverter premium Encik Danish paid (approximately RM400 more than equivalent non-inverter units) will be recovered within 8-10 months.

Customer Feedback

"As first-time homeowners, we were nervous about the process. Syahir explained everything during the site survey and gave honest advice. The installation was clean and professional — PVC trunking looks great. The Midea inverter is really quiet and cold. Our TNB bill is very reasonable. Highly recommend Total Aircond!"
