Professional Aircond Installation — Daikin, Panasonic, York & More

Aircond Installation in Petaling Jaya

Installing a new air conditioner is more than just hanging a unit on the wall and plugging it in. A proper installation ensures your aircond runs at peak efficiency, cools your room effectively, and lasts for years without problems. At PJ Kool Aircond Service, we provide professional aircond installation for all major brands across Petaling Jaya and the surrounding Klang Valley.

Whether you are installing a new unit in a freshly renovated room, replacing an old system that has reached the end of its life, or fitting out an entire home with air conditioning, our experienced installation team has you covered.

Why Professional Installation Matters

You might be tempted to save money by having a general handyman install your new aircond, but improper installation is one of the leading causes of early system failure, poor cooling performance, and void warranties. Here is why professional installation makes a real difference:

Correct piping work is critical. The copper refrigerant pipes connecting the indoor and outdoor units must be properly measured, cut, flared, and sealed. Poor flaring is the number one cause of refrigerant gas leaks, which leads to reduced cooling and the need for expensive gas recharges. Our technicians use calibrated flaring tools and check every joint for leak-free connections.

Vacuum pump evacuation is a step that many inexperienced installers skip. Before charging the system with refrigerant, the piping must be evacuated with a vacuum pump to remove all moisture and air. Moisture in the refrigerant circuit causes ice formation, corrosion, and compressor damage over time. We never skip this step.

Electrical safety cannot be compromised. Your aircond needs a properly rated circuit breaker and correctly sized wiring to operate safely. An undersized wire or a missing circuit breaker creates a fire risk. Our installations include proper electrical connections that comply with safety standards.

Drainage gradient seems like a small detail, but incorrect drainage routing is a leading cause of water leaking from aircond units. The condensate pipe must have a consistent downward slope from the indoor unit to the drain point. We ensure this gradient is correct during every installation.

Our Installation Process

Every aircond installation with PJ Kool Aircond Service begins with a free on-site survey. Our technician visits your home to assess the installation location and plan the best approach. During this visit, we evaluate several important factors.

Indoor unit placement affects cooling distribution, accessibility for maintenance, and aesthetics. We recommend locations that provide even airflow coverage across the room while keeping the unit accessible for future servicing. The unit should not be positioned directly above electronic equipment or over beds where direct cold air could cause discomfort.

Outdoor unit placement needs to consider ventilation, noise, drainage, and accessibility. The outdoor condenser needs adequate airflow to dissipate heat effectively. We identify the optimal location that provides good ventilation while minimising noise impact on your household and neighbours.

Piping route planning determines the most efficient path between indoor and outdoor units. Shorter piping runs are always preferable for both performance and cost. Where pipes need to pass through walls, we plan penetrations carefully to minimise structural impact and ensure weatherproofing.

Electrical capacity is assessed to confirm your home’s distribution board can support the additional load. A 1.5 HP unit typically requires a dedicated 15-amp circuit, while larger units may need 20-amp or higher ratings.

Based on this survey, we provide a detailed written quotation that breaks down the cost of materials, labour, and any additional work. You know exactly what you are paying for before we begin.

What We Install

PJ Kool Aircond Service installs wall-mounted split air conditioning units from all major brands available in Malaysia:

Daikin is one of the most popular brands in Petaling Jaya, known for reliability and energy efficiency. Their inverter models are particularly well-regarded for quiet operation and precise temperature control.

Panasonic offers a strong lineup of residential units with features like nanoe-X air purification and Aerowings airflow control. They are a popular choice for families who want both cooling and air quality benefits.

York has been a trusted name in Malaysian air conditioning for decades. Their units offer good value for money with solid performance in our tropical climate.

Midea provides excellent budget-friendly options without compromising on essential features. Their inverter units offer good energy efficiency at a lower price point than premium brands.

We also install units from Samsung, LG, Acson, Carrier, Toshiba, Mitsubishi, and other brands. Regardless of where you purchased your unit, we can install it professionally.

Installation Types

Basic Installation

A basic installation is suitable when the indoor and outdoor units are positioned close together, typically on the same wall or with a short piping run of up to 10 feet. This is the most common setup for bedrooms and small rooms. Piping is usually run externally along the wall and covered with PVC trunking for a neat appearance.

Standard Installation

Standard installations involve longer piping runs, concealed piping through trunking, or situations where the outdoor unit needs to be positioned further from the indoor unit. This is common in larger homes where the outdoor unit is mounted on a balcony or at ground level while the indoor unit is several rooms away.

Complex Installation

Complex installations include scenarios such as routing piping through walls during renovation, installing units at significant heights, running new electrical circuits from the distribution board, or coordinating multiple unit installations across different rooms. These require more planning, materials, and labour.

Choosing the Right Size

Selecting the correct HP (horsepower) rating for your room is essential for both comfort and energy efficiency. An undersized unit will struggle to cool the room and run constantly, driving up electricity bills. An oversized unit will short-cycle, turning on and off frequently, which wastes energy and puts stress on the compressor.

Here is a general sizing guide for Petaling Jaya homes with standard ceiling heights:

• 1.0 HP: Suitable for rooms up to 150 square feet, such as small bedrooms and study rooms
• 1.5 HP: Ideal for rooms between 150 and 250 square feet, including standard bedrooms and small living areas
• 2.0 HP: Recommended for rooms between 250 and 400 square feet, such as master bedrooms and medium living rooms
• 2.5 HP: Best for rooms between 400 and 550 square feet, including large living and dining areas

Rooms with high sun exposure, large windows, high ceilings, or heat-generating equipment (like a kitchen adjacent to the room) may require a higher HP rating. Our technician provides a personalised recommendation during the on-site survey based on your specific room conditions.

After the Installation

Once the physical installation is complete, we perform a comprehensive series of tests before handing over the system. The unit is powered on and allowed to run for a minimum testing period. We measure the supply air temperature to confirm it reaches the expected cooling level. Gas pressure is checked with manifold gauges to verify the correct charge. All electrical connections are inspected one final time.

We also walk you through the basic operation of your new aircond, including how to use the remote control, set timers, and adjust fan speeds. For inverter units, we explain how the inverter technology works differently from non-inverter models so you know what to expect in terms of noise and temperature regulation.
