Professional Aircond Installation in Petaling Jaya

Professional Aircond Installation Done Right

Installing a new air conditioner is not as simple as mounting a unit on the wall and connecting a few pipes. A properly installed aircond system runs more efficiently, lasts longer and causes fewer problems over its lifetime. Unfortunately, many budget installers cut corners — skipping the vacuum pump step, using substandard insulation, or routing piping poorly — leading to problems that only appear months or years later.

At PJ Kool Aircond Service, we install aircond units the right way. With over 20 years of experience across Petaling Jaya, Damansara, Subang and Puchong, our senior technicians have completed thousands of residential and commercial installations. We follow manufacturer-recommended procedures on every job, using quality materials and proper techniques that ensure your new aircond performs at its best from day one.

Why Installation Quality Matters

The difference between a good installation and a poor one may not be visible on the surface, but it has a massive impact on performance and longevity.

Proper Vacuum Pump Evacuation

Before refrigerant flows through the system, the copper piping must be completely free of moisture and air. A vacuum pump extracts these contaminants to create a clean, dry system. Moisture left inside the lines causes corrosion, ice formation on the evaporator coil and premature compressor failure.

This step takes an additional 15 to 20 minutes, which is why many budget installers skip it entirely. At PJ Kool Aircond Service, we never skip the vacuum pump. It is one of the most important steps in the entire installation process.

Quality Armaflex Insulation

The copper piping connecting your indoor and outdoor units carries extremely cold refrigerant. Without proper insulation, condensation forms on the pipes — causing water dripping along walls and ceilings. Poor insulation also reduces cooling efficiency, as cold energy is lost before it reaches the indoor unit.

We use genuine Armaflex insulation on all piping — not the thin, cheap alternatives that degrade within a year. Proper insulation protects against condensation and ensures maximum cooling efficiency for the life of your system.

Correct Piping Practices

Copper piping must be bent carefully to avoid kinks that restrict refrigerant flow. Joints must be properly flared and tightened to prevent leaks. The piping route should be as short and direct as possible, with proper support brackets to prevent sagging. These details matter — and they are where experienced technicians make a real difference.

Our Installation Process

Free Consultation and Site Survey

Before any installation, we visit your home or office to understand your requirements. We assess:

• Room dimensions to calculate the correct aircond capacity (HP)
• Wall structure to determine the best mounting position
• Outdoor unit placement options and accessibility
• Piping route — distance, wall penetrations and trunking requirements
• Electrical supply — existing wiring capacity and switchboard access

Based on this assessment, we recommend the right brand and capacity for your space. We are brand-neutral — our recommendation is based entirely on your needs and budget, not on dealer incentives. Not sure how much horsepower your room needs? Read our guide on how to choose the right aircond HP for your room size before we arrive.

All Major Brands Installed

We install and service aircond units from all leading manufacturers:

• Daikin — Premium energy efficiency and quiet operation
• Panasonic — Reliable performance with nanoe air purification technology
• York — Excellent value for money with strong cooling output
• Midea — Budget-friendly option with solid build quality
• Samsung — Wind-Free cooling technology for enhanced comfort
• LG — Dual Inverter compressor with 10-year warranty
• Acson — Malaysian brand with good local support
• Carrier — Global leader in HVAC engineering

We can supply the unit as part of a supply-and-install package, or install a unit you have purchased separately. Either way, the installation quality is identical.

Types of Installation

Back-to-Back — The simplest and most affordable option. The indoor and outdoor units are mounted on opposite sides of the same wall, requiring minimal piping. Ideal for bedrooms and living rooms with suitable external wall access.

Extended Piping — When the outdoor unit needs to be placed further away — on a balcony, rooftop or ground level — extended copper piping is required. Our technicians ensure proper piping support, insulation and drainage along the entire route.

Multi-Split Systems — A single outdoor unit connected to multiple indoor units in different rooms. This saves outdoor space and can be more cost-effective for homes and offices requiring cooling in several rooms.

Replacement and Upgrade — Removing an old unit and installing a new one in its place. We handle safe removal of the old system, including proper refrigerant recovery.

Clean Worksite Guarantee

We understand that aircond installation involves drilling, piping and wiring that can create dust and debris. Our team takes care to protect your furniture and flooring during the installation, and we clean up thoroughly before leaving. You receive a clean, tidy worksite with your new aircond running perfectly — not a construction zone.
