Frequently Asked Questions (FAQ) About Aircon Repair, Overhaul & Servicing

What are the signs I need an aircon repair or overhaul?
You may need an aircon repair or overhaul if you notice:

  • Air not cold, especially when stationary

  • Cooling fades quickly after gas top-up

  • Strange noises (clicking, squealing) when AC is on

  • Musty smells or foggy windows

  • Uneven cooling (one side cold, the other warm)

  • Wet passenger floor mats from clogged drains

If left unchecked, minor AC issues can escalate into costly repairs or full system failure.

❓ Why is my AC cold when driving but warm at idle?

  • Often due to a weak compressor or faulty condenser/radiator fan

  • Confirmed by checking system pressures at idle and at higher RPMs
    We recommend booking a diagnosis early to prevent further damage.

❓ What’s the difference between aircon servicing and an overhaul?

  • Servicing: Filter replacement, cleaning, gas top-ups, minor fixes

  • Repair: Fixing specific components such as expansion valves, O-rings, or blower motors

  • Overhaul: Major parts like compressor, evaporator, or condenser replaced when beyond repair

Our team will advise the most cost-effective solution based on your symptoms.

❓ How long will the repairs take?

  • Most jobs: completed same day once parts are in stock

  • Evaporator/cooling coil replacements: may take 1–2 days (requires dashboard removal)

❓ Do you also service hybrid and EV aircon systems?
Yes. Our technicians are trained in diesel, petrol, EV and hybrid HVAC:

  • Hybrid compressor repairs

  • High-voltage safety procedures

  • Heat-pump HVAC systems used in modern EVs

❓ What is the lifespan of a car air conditioning system?

  • With proper servicing, major AC components last 5–7 years

  • Neglecting maintenance can shorten lifespan and cause premature compressor/evaporator failure

❓ Is recharging necessary?
Yes. Recharging may be needed if refrigerant levels drop due to:

  • Normal wear and tear

  • Leaks in hoses, O-rings, or coils
    We check pressures and recharge with R134a or R1234yf as needed.

❓ Can a faulty AC system affect overall car performance?
Yes. A failing AC system can:

  • Put extra load on the engine

  • Reduce fuel efficiency

  • Affect overall driving comfort
    Repairing early ensures both comfort and efficiency.

❓ Do you provide warranties for aircon repairs?
Yes. We provide warranty on both parts and labour.

  • Duration depends on service or component replaced

  • All warranty details are confirmed in writing

❓ Is it safe to drive with a malfunctioning aircon?
Generally safe, but not recommended:

  • Singapore’s hot climate makes it uncomfortable and unsafe for long drives

  • Certain AC faults may strain engine components
    It’s best to get your AC repaired promptly.

Best Petrol & Diesel Car Aircon Repair in Singapore

Most petrol and diesel cars use a belt-driven compressor system powered directly by the engine. Common issues include:

  • Refrigerant leaks from hoses, O-rings, or condenser

  • Compressor clutch or pulley failure (causing squealing noises)

  • Cooling coil/evaporator leaks leading to weak cooling

  • Condenser blockages or damage from road debris

At Battery Lab, we service all major brands (Toyota, Honda, Nissan, Hyundai, BMW, Mercedes-Benz and more) using OEM or high-quality replacement parts. Our technicians ensure fast diagnosis and same-day repairs for most petrol and diesel vehicles.

📞 Contact us now for a complimentary diagnostic before it escalates into costly damage.

Best Hybrid Car Aircon Repair & Overhaul in Singapore

Hybrid vehicles like the Toyota Prius, Honda Vezel, and Lexus RX use electric compressors instead of traditional belt-driven ones. These require special compressor oil and high-voltage safety handling.

Common hybrid AC issues we fix include:

  • Electric compressor failures (no cooling or intermittent cooling)

  • High-voltage insulation faults and system shutdowns

  • Cooling coil and condenser leaks

  • Musty odours caused by evaporator mold growth

📍 Our team is trained in hybrid HVAC systems, ensuring safe, accurate repairs and the use of the correct refrigerants and oils for long-term reliability.

Electric Vehicle (EV) & Heat Pump Aircon Repair

Modern EVs such as the Tesla Model 3, Nissan Leaf, and Hyundai Ioniq feature heat-pump HVAC systems that not only cool the cabin but also manage battery temperature.

We specialise in:

  • Heat pump refrigerant leaks

  • Cabin not cooling/heating efficiently

  • Faulty electric compressors and sensors

  • Correct refrigerant & EV-safe oil handling

🛠️ With certified EV technicians, we restore comfort and performance safely while protecting your battery system.
