1. Understand Your Cooling Needs Aircon promotions

Before you even start looking at aircon models, it’s important to assess your home’s cooling requirements. Here are the key points to think about:

a) Size of the Rooms

The size of your space directly affects the cooling capacity you’ll need. A small bedroom may require only a System 1 unit, while a large living room or an open-plan apartment might need a System 3 or System 4.

• Small bedroom (9–12 sqm) → 9,000 BTU

• Medium bedroom (13–18 sqm) → 12,000 BTU

• Large living room (20–25 sqm) → 18,000 BTU or more

b) Number of Rooms to Cool

If you need to cool multiple rooms simultaneously, a multi-split system will be more cost-effective and space-saving compared to installing multiple single units.

c) Lifestyle Habits

Do you use aircon in all rooms at the same time, or just one room at night? Your usage pattern helps determine whether you need a high-capacity multi-system or just a smaller, more energy-efficient setup.

2. Know Your Aircon System Options

At LetsCool Aircon and Services, we install and maintain all types of air conditioning systems, including: aircon trunking

System 1 (Single-Split Aircon)

• Best for: Small apartments, bedrooms, or single-room use.

• How it works: One indoor unit connected to one outdoor condenser.

• Advantages: Lower cost, easy to install, energy-efficient for small spaces.

System 2 / System 3 / System 4 (Multi-Split Aircon)

• Best for: Medium to large homes with multiple rooms.

• How it works: Several indoor units connected to one outdoor condenser.

• Advantages: Saves outdoor space, allows different temperature control for each room, neater installation.

Centralised Air Conditioning (VRV / VRF Systems)

• Best for: Large houses, landed properties, or offices.

• How it works: A central outdoor unit controls airflow to multiple zones in the building.

• Advantages: Consistent cooling, sleek design (no bulky wall units), quieter operation.

3. Consider Energy Efficiency

Electricity bills can rise quickly if your aircon isn’t energy-efficient. In Singapore, air conditioners are rated by NEA’s tick system—the more ticks, the more energy savings.

• 5-Tick models are the most efficient and cost-effective in the long run.

• Inverter technology also helps by adjusting compressor speed instead of running at full power all the time.

At LetsCool Aircon, we recommend Mitsubishi, Daikin, Panasonic, Midea, Hitachi, York, Toshiba, Haier, and Sharp for their reliable energy performance and durability.

4. Check Your Installation Space

Some HDB flats and condos have restrictions on the type and placement of outdoor condensers. Our team at LetsCool conducts a free on-site survey to measure and inspect:

• Available wall and ceiling space for indoor units

• Outdoor ledge size for condensers

• Electrical load capacity

This step ensures you choose a system that not only fits your needs but also complies with building guidelines.

5. Think About Maintenance Needs Annual Service Contract

Different systems have different maintenance requirements:

• Single-split units are generally easier and cheaper to maintain.

• Multi-split systems require careful servicing because multiple indoor units share one outdoor unit.

• Central systems need professional technicians for regular checks to prevent costly breakdowns.

With LetsCool maintenance plans, you can keep your system running at peak performance while extending its lifespan.

6. Budget for the Long Term

The cheapest option upfront isn’t always the most economical in the long run. Consider:

• Initial installation cost

• Monthly electricity bills

• Maintenance and Aircon Repair costs

• Lifespan of the system

For example, a 5-tick inverter multi-split system may cost more initially but save you hundreds of dollars each year in power bills.

7. Get Professional Advice

Choosing the right aircon system is more than just picking a brand or model—it’s about matching the cooling capacity, energy efficiency, and installation design to your lifestyle and home layout.
