HDB vs Condo vs Landed: How Aircon Needs Differ in Singapore
Introduction
In Singapore, air conditioning isn’t just a comfort — it’s part of daily life. But the kind of home you live in changes what your aircon needs. Whether it’s a compact HDB flat, a modern condo, or a spacious landed property, each type of home faces its own cooling challenges.
From energy efficiency and system layout to servicing frequency, the differences matter more than most homeowners realize. This guide breaks down how aircon requirements vary across housing types in Singapore and how professional servicing from ACX keeps them running at peak performance.
Singapore Context: Cooling in a Tropical City
Singapore’s climate stays hot and humid year-round, averaging 31°C by day and 26°C by night. Air conditioners run daily, sometimes overnight. With limited ventilation in most urban housing, the system type and capacity must match both layout and lifestyle.
Key local factors influencing aircon setup:
- Space constraints: HDBs have smaller rooms; condos and landed homes vary widely.
- Building materials: Concrete and glass trap heat differently.
- Usage hours: Bedroom units run longer than living-room systems.
- Power limits: HDB electrical load is capped lower than landed properties.
Why It Matters
Choosing and maintaining the right aircon setup prevents:
- Inconsistent cooling between rooms.
- Higher electricity bills from oversized or mismatched units.
- Frequent breakdowns due to strain.
- Poor airflow or mould growth in tight spaces.
A system that fits your home type doesn’t just cool better — it lasts longer and costs less to run.
HDB Aircon Systems: Compact and Cost-Efficient
Typical Setup
Most HDB flats use multi-split inverter systems (1 outdoor compressor powering 2–4 indoor units).
| Feature | Details |
|---|---|
| Common Brands | Daikin, Mitsubishi Electric, Panasonic |
| Cooling Zones | 2–3 bedrooms + living room |
| Power Load Limit | 23–30 amps |
| Popular Model | System 3 or System 4 inverter |
Cooling Characteristics
- Prioritizes bedrooms, where aircon runs longest.
- Limited outdoor space restricts compressor size.
- Indoor pipes and wiring run compactly through walls.
Maintenance Needs
- Clean filters every 3 weeks to prevent dust buildup.
- General servicing every 3–4 months.
- Chemical cleaning once a year to remove internal mould.
Common Issues
- Weak cooling when multiple units run simultaneously.
- Water leakage due to frequent overnight use.
- Drain pipe blockages from compact layouts.
Tip: Schedule servicing during non-peak hours to save cost — ACX offers weekday plans ideal for HDB homeowners.
Condo Aircon Systems: Style Meets Complexity
Typical Setup
Condominiums feature a range of layouts, from studio units to penthouses. Many use system 4 or VRV (Variable Refrigerant Volume) aircon types.
| Feature | Details |
|---|---|
| Common Brands | Mitsubishi Heavy Industries, Daikin, Toshiba |
| Cooling Zones | Bedrooms, living area, dining room |
| Power Load Limit | 30–40 amps |
| Installation | Hidden piping and concealed ceiling cassettes in premium units |
Cooling Characteristics
- Aesthetic integration (false ceilings, built-in ducts).
- Higher cooling capacity and wider air throw.
- Quieter operation due to outdoor compressor placement.
Maintenance Needs
- General servicing every 3–6 months depending on usage.
- Chemical wash or overhaul yearly for concealed systems.
- Drain checks crucial for units with false ceilings.
Common Issues
- Hidden leaks that stain ceiling boards.
- Hard-to-access drainage or blower systems.
- Irregular cooling when multiple fan coils share one compressor.
Condos need professional technicians familiar with concealed aircon designs, like those from ACX, to ensure no damage to ceiling panels or wiring.
Landed Property Aircon Systems: Power and Custom Cooling
Typical Setup
Landed homes, from terrace to bungalows, use multi-zone ducted systems or multiple outdoor compressors for full control over large spaces.
| Feature | Details |
|---|---|
| Common Brands | Daikin VRV, LG, Fujitsu |
| Cooling Zones | Multiple floors, living rooms, home offices |
| Power Load Limit | 45 amps and above |
| Installation | Combination of split and ducted units |
Cooling Characteristics
- Greater flexibility — some rooms run day and night, others occasionally.
- Large living areas need higher BTU capacity.
- Air distribution often through hidden ducts or ceiling vents.
Maintenance Needs
- General cleaning every 3–4 months.
- Chemical overhaul every 9–12 months for ducted systems.
- Regular gas pressure checks for multi-compressor setups.
Common Issues
- Uneven cooling due to long duct paths.
- Condensation near ceiling vents.
- Energy waste if zones run unnecessarily.
Landed homeowners often benefit from annual maintenance contracts — ACX provides full-house service packages for convenience and consistency.
Comparison Summary
| Feature | HDB | Condo | Landed |
|---|---|---|---|
| Typical System | Split / Multi-split | Multi-split / VRV | Multi-zone / Ducted |
| No. of Units | 2–4 | 3–6 | 5+ |
| Average Service Cost per Unit | $60–$90 | $80–$120 | $100–$150 |
| Chemical Wash Frequency | Once a year | Once a year | 1–2 times a year |
| Common Issues | Drain blockage, low cooling | Ceiling leaks, airflow imbalance | Duct condensation, power load |
| Ideal Service Provider | Residential specialist | Concealed-system expert | Full-property maintenance team |
Energy Efficiency Tips by Home Type
For HDBs:
- Set temperature to 25°C; lower settings strain small compressors.
- Clean filters monthly.
- Use bedroom fans to improve circulation.
For Condos:
- Install smart thermostats to manage zones efficiently.
- Check ceiling vents for moisture spots.
- Don’t run all units simultaneously for long periods.
For Landed Homes:
- Invest in inverter VRV systems for large spaces.
- Maintain ducts and vents to prevent energy loss.
- Use programmable timers for seldom-used rooms.

Frequently Asked Questions
1. Does condo aircon servicing cost more than HDB?
Yes — due to concealed designs and harder access, condo units usually cost slightly more per unit.
2. Is chemical cleaning necessary for all home types?
Yes, at least once a year. Landed homes with ducted systems may need it twice annually.
3. How long does general servicing take?
About 30–60 minutes per unit, depending on system complexity.
4. Can I use a standard package for different home types?
No — choose a service plan tailored to your aircon system and number of units.
5. Why do HDB units leak more often?
Compact layouts and overnight use increase condensation and blockage risks.
6. Are VRV systems better for landed homes?
Yes, they offer energy-efficient zoning for large properties.
7. Does ACX service all home types?
Absolutely — from HDBs to large landed properties, with certified technicians for each system type.
Conclusion
Every Singapore home cools differently. HDBs need compact efficiency, condos demand delicate handling for hidden units, and landed homes rely on power and control. Understanding these distinctions helps you choose the right maintenance plan — saving energy, money, and hassle.
