Aircond Installation Guide Malaysia —
Everything you need to know before installing a new aircond in Malaysia — HP sizing, pipe routing, electrical points, installation costs.
Choosing the Right HP for Your Room
- 1.0 HP: Up to 100 sq ft
- 1.5 HP: 100–200 sq ft (most common)
- 2.0 HP: 200–300 sq ft

- 3.0 HP: 400–600 sq ft
Always round up if near the top of a range. West-facing rooms need higher HP.

Common Installation Mistakes to Avoid
Poor installation causes problems that persist for the entire life of the unit. The most common mistakes from unqualified installers include: not vacuuming the refrigerant lines before charging (air and moisture in the system degrade compressor performance), undersizing copper pipe (causes higher operating pressure and reduced efficiency), installing the indoor unit without adequate drainage fall (water backs up and leaks), and mounting the outdoor unit in a position with insufficient clearance for heat rejection. KL Renovator technicians are trained and equipped to avoid all of these mistakes on every installation.

After Installation — First 30 Days
In the first 30 days after installation, monitor the unit for: water dripping from the indoor unit (indicates a drainage slope issue), unusual noise during compressor startup (may indicate a refrigerant charge issue), cooling performance that does not match the expected output for the HP size, or any smell from the unit beyond the typical "new unit" smell. KL Renovator's 1-month workmanship warranty covers any issues arising from the installation itself during this period. WhatsApp +60 18-298 3573 immediately if any of these are observed.
Electrical Point Requirements
Every aircond requires a dedicated 15-amp electrical point — it cannot share a socket with other appliances. If your room does not have a dedicated aircond point, KL Renovator can install one as part of the installation visit for RM 100 additional. For units 3.0 HP and above, a 20-amp dedicated circuit is recommended to handle the higher compressor startup current. The electrical point must be within 2–3 metres of the indoor unit location for standard installation. Units requiring longer cable runs will be quoted accordingly before work begins.
After Installation
In the first 30 days, monitor for water dripping, unusual noise, or weaker than expected cooling. KL Renovator's 1-month workmanship warranty covers all installation workmanship issues. WhatsApp +60 18-298 3573 immediately if any concern arises post-installation.
