Choosing the right aircon system for your flat is one of the most important decisions for comfort and long-term savings. In Singapore’s hot and humid climate, your air conditioner will likely run daily. Selecting the wrong system can lead to problems like aircon not cold, frequent aircon water leakaging, rising electricity bills, and repeated aircon repair Singapore visits.

So how do you make the right choice? In this guide, we’ll break it down into simple steps to help you choose wisely — and avoid costly mistakes.
Understand Your Flat Size and Cooling Needs
The first step in choosing the right aircon system is evaluating your flat’s layout and cooling requirements.
Room Size & BTU Capacity
Each room requires a specific cooling capacity (BTU). A unit that’s too small will struggle to cool the space, while one that’s too powerful wastes energy and increases humidity issues.
If your aircon is underpowered, you may constantly feel your aircon not cold, even when set to low temperatures. This often leads homeowners to request unnecessary aircon gas top up, when the real problem is incorrect sizing.
Number of Rooms
Most flats in Singapore opt for multi-split systems such as:
System 2 (2 indoor units)
System 3 (3 indoor units)
System 4 (4 indoor units)
Choosing the correct system ensures balanced cooling and prevents overloading the compressor, reducing the need for frequent aircon compressor servicing.
Usage Pattern
If you work from home and use aircon all day, invest in an energy-efficient inverter system. It reduces electricity bills and minimizes wear and tear, lowering the need for repeated aircon repair Singapore.
Professional consultation from LetsCool Aircon and Services Singapore ensures proper system recommendation based on your flat layout and lifestyle.
Choose Energy Efficiency and Long-Term Maintenance Support
Buying an aircon system isn’t just about upfront cost. Long-term maintenance plays a crucial role in performance and savings.
Energy Efficiency Ratings
Look for systems with high energy efficiency ratings. Energy-saving units reduce monthly bills and place less stress on components, preventing issues like aircon light blinking or sudden aircon error code alerts.

Maintenance Requirements
Every aircon system requires regular aircon servicing Singapore. Without proper maintenance, dirt buildup causes:
Weak airflow
Water leakage
Bad odours
Compressor strain
Routine aircon general servicing every 3–4 months keeps your system in optimal condition.
Deep Cleaning Options
Over time, normal servicing may not be enough. Depending on usage, you may need:
Aircon steam wash – to remove surface dirt and bacteria
Aircon chemical wash – for deeper cleaning of coils and drainage
Aircon chemical overhaul – for severely clogged systems
Choosing a system that is easy to dismantle and service reduces future maintenance costs.
Signing up for an aircon service contract with a reliable company ensures scheduled servicing and early detection of worn aircon spare parts.
Work with a Professional Installation Company
Even the best aircon brand can fail if installed incorrectly. Proper aircon installation Singapore is essential for long-term performance.
Correct Piping & Drainage
Poor installation often leads to aircon water leakaging due to improper drainage slope or pipe insulation. This problem is common in flats where inexperienced installers cut corners.

Electrical Safety
Incorrect wiring may trigger frequent aircon error code warnings or cause the aircon light blinking unexpectedly.
Proper Compressor Placement
The outdoor unit must have adequate ventilation. Overheating compressors require frequent aircon compressor servicing and can shorten system lifespan.
That’s why many homeowners trust LetsCool Aircon and Services Singapore for professional installation and after-sales service. Their team ensures proper setup, testing, and guidance on maintaining your system.
Don’t Ignore After-Sales Support and Spare Parts Availability
When choosing the right aircon system, consider availability of aircon spare parts. Systems with easily available parts are cheaper to maintain and repair.
Reliable companies offering best aircon servicing Singapore will:
Use genuine spare parts
Provide transparent pricing
Offer seasonal aircon promotion packages
Provide comprehensive maintenance plans
This ensures peace of mind throughout the lifespan of your unit.
Common Mistakes to Avoid When Choosing an Aircon
Here are mistakes many flat owners make:
❌ Choosing based on price alone❌ Ignoring energy efficiency ratings❌ Hiring inexperienced installers❌ Skipping regular servicing❌ Delaying minor issues like blinking lights or small leaks
These mistakes often result in expensive aircon repair Singapore services later.
Why Regular Servicing Matters After Installation
After selecting the right system, maintenance determines how long it lasts.
Routine aircon servicing Singapore prevents:
Cooling problems
Water leakage
Mold buildup
Electrical faults
Compressor failure
If you notice your aircon not cold, water dripping, or aircon light blinking, don’t delay. Early intervention prevents costly repairs.
Regular aircon general servicing, occasional aircon steam wash, and timely aircon chemical wash keep your system running smoothly. In more severe cases, an aircon chemical overhaul restores performance and efficiency.
