What does a full aircon tune‑up include?

Aircon Servicing

In Singapore’s hot and humid climate, a well-functioning air conditioning system isn’t a luxury—it’s a necessity. Whether in homes or commercial buildings, air-conditioners work overtime to keep spaces comfortable year-round. However, like any mechanical system, your air-con needs regular maintenance to stay efficient and reliable. That’s where a full air-con tune-up comes in.

At LetsCool Aircon and Services in Singapore, we’ve spent over 25 years helping homeowners and businesses enjoy cool, clean air through expert servicing and maintenance. In this article, we’ll walk you through what a complete air-con tune-up involves and why it’s crucial for your unit’s performance, longevity, and energy efficiency. View more.

Why a Full AirCon Tune-Up Matters

Many users only pay attention to their AC when it starts showing signs of trouble—poor cooling, water leakage, or strange noises. But by that point, damage may already have occurred. Preventive tune-ups are a smart investment to:

• Improve cooling performance

• Enhance energy efficiency

• Prolong the lifespan of your unit

• Prevent costly breakdowns

• Improve indoor air quality

A full air-con tune-up is not just a quick clean—it’s a detailed process that ensures every component of your system is working optimally.

What’s Included in a Full Aircon Tune-Up?

At LetsCool Aircon and Services, our comprehensive aircon tune-up includes a wide range of services that cover both the indoor and outdoor units. Here’s what’s involved:

1. Inspection of the Entire System

We begin with a complete diagnostic inspection of your air-con system. This includes:

• Checking thermostat settings and function

• Inspecting electrical connections

• Verifying the refrigerant level

• Examining components for wear and tear

• Assessing overall system performance

This helps us identify any existing issues or potential risks early on.

2. Filter Cleaning or Replacement

One of the most common causes of poor airflow is a dirty air filter. We either:

• Clean reusable filters thoroughly using water and mild detergent, or

• Replace disposable filters if they are too clogged or damaged.

Clean filters improve airflow, cooling efficiency, and indoor air quality by removing dust, pollen, and other allergens.

3. Evaporator and Condenser Coil Cleaning

Over time, both the evaporator coil (indoor unit) and the condenser coil (outdoor unit) accumulate dirt, which restricts heat transfer and causes the unit to overwork. We:

• Gently clean coils to remove dust and grime

• Apply coil cleaner for deep cleaning if needed

• Ensure proper coil drainage to prevent mould growth

This step is essential to restore efficient heat exchange and prevent compressor strain.

4. Drain Line and Tray Cleaning

Blocked or dirty condensate drain lines can cause water to leak from your air-con unit. During the tune-up, we:

• Clear any clogs in the drainage pipe

• Clean and disinfect the drain tray

• Ensure proper water flow and eliminate foul odours

This helps prevent water damage, leaks, and microbial growth inside the unit.

5. Fan and Blower Cleaning

The blower and fan blades are cleaned to remove accumulated dirt, which can reduce airflow and lead to uneven cooling or unnecessary noise.

• Indoor blower wheel is dusted and washed

• Outdoor fan blades are wiped and balanced

• Motor performance is tested

Clean fans help ensure smoother operation and quieter performance.

6. Refrigerant Level Check

Refrigerant (gas) is critical for effective cooling. Low refrigerant levels often indicate a leak, which can damage the compressor if left unaddressed.

• We check the refrigerant pressure levels using professional gauges

• Inspect for any signs of leakage

• Perform a gas top-up if necessary using the correct refrigerant type

Note: If a leak is found, we offer leak testing and repair services before topping up the gas.

7. Electrical Components Check

We inspect and tighten all electrical connections and components, including:

• Capacitors

• Contactors

• Relays

• Wiring and terminals

This step prevents electrical faults, short circuits, or unexpected power failures.

8. Thermostat Calibration and Testing

A faulty thermostat can cause inaccurate temperature regulation. We:

• Test and calibrate the thermostat for accuracy

• Replace faulty thermostats if needed

• Recommend smart thermostat upgrades for better control and efficiency

9. Performance Testing

After servicing, our technicians test the aircon system to ensure everything is functioning smoothly. We:

• Measure air temperature at vents

• Check airflow strength

• Monitor the cycling process of the system

• Listen for any unusual noises

We won’t leave until your system is running as efficiently as possible.

How Often Should You Schedule a Tune-Up?

In Singapore’s climate, it’s best to schedule a full air-con tune-up at least once a year, even if the unit seems to be working fine. For systems used daily or in commercial settings, we recommend servicing every 3 to 6 months to maintain optimal performance.

At LetsCool Aircon, we also offer contract maintenance plans that include scheduled tune-ups, priority service, and discounted repair costs—ideal for both residential and commercial clients.
