Aircon Services

Becoming a new homeowner in Singapore is an exciting milestone, but along with the joy of settling into your new home comes the responsibility of maintaining key systems that keep your living space comfortable. One of the most essential yet often overlooked elements is your air conditioning system.

In Singapore’s tropical climate, where heat and humidity are present year-round, having a reliable air conditioner is not just a convenience — it’s a necessity. Whether your unit is brand new or previously installed by the previous owner, scheduling a proper aircon service should be a top priority once you’ve moved in.

At LetsCool Aircon and Services Singapore, we’ve helped countless homeowners take control of their indoor comfort from day one. With over 25 years of industry experience, we’ve put together this detailed first-time aircon service checklist to help new homeowners stay cool, comfortable, and confident. View more.

  • 1. Check the Age and Condition of Your Aircon Unit
The first thing you should do is determine how old your aircon unit is and what condition it’s in. If the system was inherited from the previous owner, find out:

  • The brand and model

  • The installation date

  • The last date of service or repair

  • Whether the unit is still under warranty

At LetsCool, we offer a free site survey, during which our technicians assess the unit’s health and make recommendations based on its age, performance, and condition.

  • 2. Schedule a Professional Aircon Inspection and Servicing
Even if your aircon appears to be running fine, scheduling a full servicing is essential. Over time, dust, mold, and dirt accumulate inside the unit, especially if the previous owners didn’t maintain it regularly. A routine aircon service includes:

  • Cleaning of air filters, blower, and fan coils

  • Checking refrigerant levels and gas top-up (if needed)

  • Inspecting electrical components

  • Clearing drainage pipes to prevent water leakage

  • Testing overall cooling performance

Our technicians at LetsCool use professional-grade tools and follow a systematic process to ensure your unit is clean, safe, and running efficiently from day one.

  • 3. Consider a Chemical Wash or Chemical Overhaul (If Needed)
If your aircon is emitting foul smells, not cooling effectively, or making loud noises, it may require more than a basic cleaning. That’s where a chemical wash or chemical overhaul comes in.

A chemical wash involves dismantling key parts and cleaning them with safe chemicals to remove stubborn dirt, mold, and bacteria. A chemical overhaul goes even deeper — ideal for older or heavily clogged systems.

At LetsCool, we offer expert chemical servicing with a 90-day workmanship warranty, ensuring peace of mind for all new homeowners.

  • 4. Check for Aircon Installation Compliance
For HDB homeowners, it’s important to ensure that the aircon system is installed in compliance with HDB guidelines. Improper installation can lead to safety risks and costly repairs later.

Our BCA-trained installers are familiar with all HDB aircon regulations, including compressor placement, pipe routing, electrical load limits, and more. If we spot any compliance issues during inspection, we’ll recommend the safest corrective actions.

For private properties or condos, we ensure clean, secure installations that respect estate management guidelines and structural limits.

  • 5. Evaluate if the Aircon System Matches Your Home Layout
Different homes have different cooling needs. A System 2 or System 3 unit may be sufficient for a 3- or 4-room HDB flat, while landed properties or larger condos may require a centralized or System 4 solution.

If you feel that the current setup is overpowered or underpowered for your space, we can help assess and recommend the most energy-efficient system for your layout — whether it’s Mitsubishi Electric, Daikin, Panasonic, or other top-tier brands.

  • 6. Learn How to Maintain Your Aircon Between Services
Aircon maintenance doesn’t end with professional servicing. As a homeowner, you should follow simple habits to keep your unit in top condition:

  • Clean the air filters every 2–3 weeks to maintain airflow and cooling efficiency.

  • Keep the external compressor area free from obstruction.

  • Close doors and windows when using the aircon to prevent overworking the unit.

  • Avoid setting the temperature too low (ideal range is 24–26°C for comfort and energy savings).

  • Listen for unusual sounds or changes in airflow — these could be early signs of trouble.

Let LetsCool technicians are always happy to share tips during every service visit.

  • 7. Sign Up for an Aircon Servicing Contract
As a new homeowner, setting a consistent maintenance routine from the start can save you from costly repairs later. LetsCool offers affordable aircon servicing contracts for both HDB and private homes, with options for:

  • Quarterly servicing

  • Bi-monthly maintenance

  • Annual contracts for multiple systems

  • 8. Know Who to Call for Urgent Repairs
No matter how well you maintain your aircon, problems can arise. As a new homeowner, you’ll want to have a reliable service provider on speed dial.
