• Ensuring smooth airflow and efficient operation   

Aircon maintenance comes in different levels depending on your system’s condition. Understanding the difference between general servicing and a chemical wash helps you choose the right solution for your aircon.

• General Servicing
  This is a routine cleaning process that focuses on essential parts such as filters, coils, and drain pans. It helps maintain airflow, prevents minor blockages, and keeps the unit running smoothly. General servicing is ideal for regular maintenance and for aircon units that are in good working condition.
• Chemical Wash
  This is a deep cleaning procedure that uses safe, non-acidic chemical solutions to break down and remove stubborn dirt, grease, Mold, and bacteria from coils, pipes, and internal components. A chemical wash restores cooling efficiency and improves indoor air quality. It is recommended for aircon units with heavy buildup, foul Odors, or poor performance.

Recommendation: For long-term care, schedule general servicing every 3–6 months and opt for a chemical wash when your aircon shows signs of inefficiency or persistent dirt buildup. PeakCool’s technicians use non-acid solutions to protect your aircon coils from corrosion while delivering a thorough clean.

While homeowners can handle simple tasks such as cleaning or replacing air filters, professional servicing is essential for maintaining the safety, efficiency, and lifespan of your aircon system. Trained technicians can perform detailed checks and maintenance that go beyond basic cleaning, including:

• Refrigerant Level Checks

  Ensuring the refrigerant is at the correct level prevents cooling issues and protects the compressor from damage.

• Coil and Pipe Cleaning

  Professionals use the right tools and solutions to thoroughly clean coils and pipes, improving airflow and efficiency while preventing Mold buildup.

• Electrical Component Inspections

  Checking wiring, controls, and connections helps identify early faults, reducing the risk of electrical failures and safety hazards.

  In short: Professional servicing ensures your aircon operates safely, efficiently, and reliably, saving you from costly breakdowns in the long run.

Regular servicing helps to:

• Reduce energy consumption and electricity bills
• Improve cooling efficiency and airflow
• Maintain clean indoor air, reducing allergens and asthma triggers
• Extend the lifespan of your unit
• Prevent costly repairs

Like any appliance, your aircon gives early warning signs when it needs attention. Ignoring these indicators can lead to costly repairs or even a full breakdown. Here are the most common signs that your unit needs servicing:

• Weak or Uneven Cooling

  If your aircon is running but not cooling effectively, or if certain rooms feel warmer than others, it may be due to clogged filters, low refrigerant, or mechanical issues.

• Water Leakage or Unusual Noises

  Leaks around the unit or sounds like rattling, buzzing, or grinding often point to blocked drainage, loose parts, or a failing motor.

• Foul or Strange Odors

  Musty smells usually signal Mold or bacteria growth inside the system, while burning Odors may indicate electrical issues.

• Higher-than-Normal Electricity Bills

  A sudden spike in your energy bills without increased usage can mean your aircon is working harder than it should be due to inefficiency.

• Ice Buildup on the Coils

  Frozen coils are a clear sign of restricted airflow, dirty filters, or refrigerant problems that need professional servicing.

Recommendation: Regular maintenance prevents these problems and ensures smooth performance. With PeakCool Aircon Services, you can count on expert servicing to keep your system efficient, reliable, and long-lasting.

Yes. Even new aircon units benefit from regular servicing to:

• Maintain warranty coverage
• Ensure optimal cooling efficiency
• Prevent early wear and tear

If you notice poor cooling, strange Odors, or unusual sounds from your AC, it should be serviced. Booking a professional inspection ensures the system is functioning safely and efficiently.

Even unused AC units accumulate dust, dirt, and Mold, and electrical faults can still occur. Servicing all units ensures they work effectively and efficiently when you need them.

• Use heat-blocking blinds and curtains to reduce indoor heat
• Install smart thermostats with climate control and eco modes
• Keep fans on “auto” so they shift to low or turn off once desired temperature is reached
• Set thermostats to 25–26°C together with fan
• Ensure regular servicing so broken parts or blocked filters don’t increase electricity usage

Too much moisture in the air makes you hot, uncomfortable, and can damage your home. Excess humidity causes Mold growth, condensation, structural damage, and wood rot, and can also affect your health by triggering respiratory problems, allergies, and sleep interruptions. Your AC naturally helps reduce indoor humidity by removing warm, moist air. Persistent high humidity may indicate mechanical issues, which require professional servicing.

Regular AC servicing improves reliability and durability. Replacing worn parts early, keeping the system clean, and maintaining efficiency reduces strain on key components and prevents expensive damage.

Ceiling fans don’t reduce the temperature, but the air circulation can make a room feel 3–4°C cooler. This allows you to set your AC thermostat higher, saving 30–40% on electricity bills.

Your aircon may still be running, but that doesn’t always mean it’s performing properly. Paying attention to early warning signs can save you from sudden breakdowns and costly repairs. Watch out for these common indicators:

• Weak or Warm Airflow – Air coming from vents feels weak or not cool enough.
• Unusual Noises – Grinding, squeaking, or rattling sounds suggest internal issues.
• Moisture or Leakage – Water pooling or refrigerant leaks around the unit.
• Foul or Strange Odors – Musty or burning smells could mean Mold or electrical faults.
• High Energy Bills – A sudden spike in electricity costs often signals poor efficiency.

If you notice any of these signs, it’s best to schedule a professional inspection with PeakCool before the issue gets worse.

Before you call a technician, it’s worth checking a few simple things yourself. Sometimes, the issue can be minor and easily fixed without professional help. Here are the key things to inspect:

• Power Supply
  • Make sure your home has power and that the air conditioner is properly plugged in. A loose connection or power outage may be the cause.
• AC Filter
  • Check if the filter is dirty or clogged. A blocked filter can restrict airflow and make the AC appear faulty. Cleaning or replacing it may solve the problem.
• Thermostat Settings
  • Verify that the thermostat is set to “cool” mode and at the desired temperature. Also, check if the batteries need replacing.
• Circuit Breaker
  • Inspect your electrical panel to ensure the AC breaker hasn’t tripped. If it’s switched off, reset it and test the unit again.

Over time, air conditioners show signs of wear and reduced efficiency. Knowing when to call for a repair or consider a full replacement can save you from unexpected breakdowns and high costs. Here are the most common indicators:

• Lack of Cool Air or Weak Airflow

  If your AC is running but not producing sufficient cool air, or if the airflow feels weak, it may indicate issues with the compressor, ducts, or motor.

• Moisture Buildup or Leakage

  Excess water around the unit or refrigerant leaks are serious concerns that require immediate attention. Neglecting them can cause damage to your home and health risks.

• Strange Sounds or Vibrations

  Unusual noises such as grinding, rattling, or buzzing may point to loosen parts, motor issues, or failing components.

• Unpleasant or Foul Smells

  Bad Odors coming from the vents may be due to Mold growth, burnt-out wiring, or contaminated filters.

• Rising Energy Bills

  A sudden increase in your electricity bill without any change in usage habits often signals that your AC is losing efficiency.

• Frequent or Costly Repairs

  If you find yourself calling for service too often, or if the repair costs keep adding up, it may be more economical to replace your AC with a new, energy-efficient unit.
