HDB, Condo & Landed Property Systems

Cool Earth Aircon is a licensed aircon installation company based in Singapore with over 600 completed installation projects since 2007. A properly installed air conditioning system is the foundation of reliable, efficient cooling for years to come. While the brand and model you choose certainly matter, the quality of the installation is equally - if not more - important. Poor installation leads to refrigerant leaks, drainage problems, excessive noise, and premature system failure, regardless of how premium the equipment is.

Our team handles residential and commercial aircon installations with the same care and attention to detail, whether it is a single-split unit for a studio apartment or a System 4 multi-split setup for a five-bedroom house. Cool Earth Aircon’s certified technicians follow manufacturer specifications and Building and Construction Authority (BCA) regulations to ensure your system performs as designed. We also provide ongoing aircon servicing to keep your new system running at peak efficiency from day one.

Choosing the Right Aircon System

Selecting the correct aircon system involves more than just picking a brand. Room size, ceiling height, sun exposure, insulation quality, and the number of occupants all influence the cooling capacity required. An undersized system will struggle to cool the room, running constantly and consuming excessive electricity. An oversized system cycles on and off too frequently, creating uncomfortable temperature swings and wasting energy.

System Types We Install

Wall-Mounted Split Systems - The most popular choice for Singapore homes. Indoor fan coil units are compact and wall-mounted, connected to an outdoor condensing unit via copper piping. Available as System 1 (single-split), System 2, System 3, or System 4 (multi-split with multiple indoor units sharing one outdoor unit). Most modern systems use inverter technology for quieter operation and lower electricity bills. Ideal for HDB flats and condominiums.

Ceiling Cassette Systems - Recessed into the ceiling for a clean, unobtrusive look. Often found in condominiums, offices, and commercial spaces. Provides excellent airflow distribution across the room. Requires sufficient ceiling void space for installation.

Ducted Systems - The indoor unit and ductwork are concealed within the ceiling, with only supply and return grilles visible. Offers the cleanest aesthetics but requires more extensive installation work. Common in high-end condominiums and landed properties.

Brands We Supply and Install

We are authorised to supply and install all major aircon brands in Singapore. Our team has extensive experience with each brand’s specific installation requirements and best practices.

  • Daikin - Market leader in Singapore, known for reliability and energy efficiency
  • Mitsubishi Electric - Excellent build quality and quiet operation
  • Mitsubishi Heavy Industries - Good value with strong performance
  • LG - Innovative features and competitive pricing
  • Panasonic - Reliable Japanese engineering with nanoe-G air purification
  • Fujitsu - Quiet operation with strong cooling performance

We provide honest, brand-agnostic advice based on your specific requirements and budget. We do not push any particular brand - our goal is to match you with the system that best suits your needs.

How We Handle Your Aircon Installation

Free On-Site Survey

We begin with a complimentary visit to your property anywhere in Singapore, from Tampines and Bedok to Woodlands and Jurong. Our installation specialist measures each room, assesses the layout, checks the aircon ledge or outdoor unit placement options, and discusses your preferences. This survey typically takes 30 to 45 minutes for a standard HDB flat.

Detailed Quotation

Following the survey, we prepare a comprehensive quotation that breaks down equipment costs, materials (copper piping, trunking, brackets, wiring), and labour charges. There are no hidden costs - the quotation covers everything needed for a complete, professional installation. For a breakdown of typical costs, see our guide on aircon installation costs in Singapore.

Professional Installation

On installation day, our team arrives with all equipment and materials. The typical workflow includes:

  1. Bracket and mounting plate installation - Securely fixed to the wall using appropriate anchors
  2. Piping and trunking - Copper piping is cut to length, flared, and connected. Trunking is installed neatly along walls and ceilings
  3. Electrical wiring - Power supply connected from the aircon point to each indoor and outdoor unit
  4. Drainage - Condensate drain pipes routed to the nearest drain point with proper gradient
  5. Outdoor unit placement - Condenser mounted on the aircon ledge or bracket with adequate ventilation clearance

Vacuum Testing and Commissioning

Before introducing refrigerant, we vacuum-test the piping system to remove moisture and check for leaks. This step is critical - moisture in the system causes ice formation and compressor damage. Only after the system passes vacuum and pressure tests do we release the refrigerant and commission the unit.

What HDB Flat Owners Need to Know

HDB flats have specific requirements and constraints for aircon installation that we are thoroughly familiar with:

  • Aircon ledge regulations - Outdoor units must be placed on designated aircon ledges or brackets approved by HDB
  • Drain pipe routing - Condensate must be routed to approved drain points, not simply to the exterior wall
  • Trunking placement - We plan trunking routes that are both functional and aesthetically acceptable
  • Neighbour consideration - Outdoor units are positioned and mounted to minimise noise transmission to adjacent units

For BTO flat owners coordinating with renovation contractors, we offer flexible scheduling and can work around other trades to ensure smooth project completion.

Ongoing Servicing After Your Install

Our relationship with you does not end at installation. We register your manufacturer warranty, provide operating instructions, and recommend a servicing schedule to keep your new system running optimally. Most brands include a standard 1-year parts warranty and 5-year compressor warranty; ask us about extended warranty options for additional peace of mind. If you are purchasing an energy-efficient inverter system, you may also be eligible to offset costs using NEA Climate Vouchers. Our quarterly servicing packages start at S$55 for 2 units, with further multi-unit discounts (2026 pricing), ensuring your investment stays protected.

Frequently Asked Questions

How long does aircon installation take?
A standard installation for a 3 to 4 unit system in an HDB flat typically takes one full day (6 to 8 hours). Larger systems or complex layouts in condos may require two days. We will provide a time estimate during the site survey.

Do I need to prepare anything before installation?
Please ensure the installation areas are clear of furniture and personal items. If you are renovating, we recommend scheduling the aircon installation after painting but before major furniture delivery. We will discuss preparation requirements during the site survey.
What warranty comes with the installation?
All installations come with a 1-year workmanship warranty from Cool Earth covering piping, wiring, and drainage. The aircon equipment carries the manufacturer's standard warranty, typically 1 year for parts and 5 years for the compressor. We register your warranty with the manufacturer on your behalf.
Can you install an aircon system in my HDB BTO flat?
Yes, we regularly install aircon systems in new BTO flats. We are familiar with HDB regulations regarding aircon ledge usage, trunking placement, and drain pipe routing. We coordinate with your renovation contractor if needed to ensure smooth installation.
How much does it cost to install an aircon in Singapore?
As of 2026, aircon installation in Singapore typically starts from around S$850 for a single-split system (System 1) and ranges up to S$4,300 or more for a System 4 or System 5 multi-split setup. The final price depends on the brand, number of fan coil units, piping length, and property layout. We provide a free on-site survey and detailed quotation so you know the exact cost before any work begins.
