Why Professional Aircond Installation Matters — Avoid These 5 Costly Mistakes

Installing a new air conditioner may seem simple, but poor installation can lead to higher electricity bills, noisy operation, and even system failure. At Thiam Seng Electrical Trading Co., we’ve seen many cases where customers had to spend more fixing problems caused by improper installation. Let’s look at the top 5 mistakes you should avoid — and why hiring professionals makes all the difference.

1. Wrong Aircond Size or Capacity

Choosing the wrong BTU size is one of the most common mistakes. An undersized unit will run continuously, wasting energy, while an oversized one cools too fast without proper humidity control. Our team provides a free site assessment to calculate the correct BTU for your space.

2. Poor Piping and Drainage Installation

Improper copper piping or poor drainage can cause water leakage and reduced cooling efficiency. Our certified technicians ensure correct pipe length, insulation, and angle for smooth drainage and long-lasting performance.

3. Incorrect Outdoor Unit Placement

Placing the outdoor condenser in a hot, enclosed area can cause overheating and shorten compressor lifespan. We follow manufacturer recommendations for optimal ventilation and accessibility, ensuring your aircond performs efficiently year-round.

4. Ignoring Electrical Safety

DIY installation or unlicensed contractors often overlook proper circuit breakers and grounding. Our licensed electricians comply with Suruhanjaya Tenaga (ST) safety standards, preventing electrical hazards and ensuring warranty validity.

5. No Proper Testing or Vacuuming

Skipping the vacuuming process before gas release allows moisture and air to enter the system — a common cause of refrigerant issues. Our technicians always vacuum and pressure-test every unit before final operation.

With over 38 years of experience in aircond installation, service, and repair, we are a trusted dealer for Panasonic, Haier, and Midea air conditioners. We provide professional workmanship, energy-efficient solutions, and post-installation support throughout Petaling Jaya and Selangor.
