Daikin Aircon Servicing Singapore
Expert Daikin aircon servicing, repair, and installation by direct technicians with 20+ years of experience. We know every Daikin model inside out — from the iSmile series to VRV commercial systems.
Why Your Daikin Aircon Needs Specialist Care
Daikin is the world's largest aircon manufacturer and the most popular brand in Singapore homes. Their inverter technology, intelligent eye sensors, and Streamer discharge systems are designed for maximum efficiency — but only when properly maintained. A neglected Daikin unit loses up to 30% cooling efficiency within the first year.
Our technicians have been servicing Daikin units since 2003, when Billy Aircon first opened. We understand the specific engineering behind Daikin's compressor technology, from the swing compressor in older models to the advanced hermetic scroll compressors in their latest inverter systems. This means we diagnose problems faster and avoid the guesswork that leads to unnecessary part replacements.
Whether you have a Daikin iSmile wall-mounted split, a ceiling cassette in your office, or a multi-split MKS system serving your whole HDB flat, our team knows exactly what each model needs. We carry genuine Daikin-compatible parts and refrigerant so most repairs are completed in a single visit.

These are the most frequent Daikin issues our technicians encounter. We resolve most of them in a single visit.
Blinking Green Light / Error Codes
Daikin units communicate errors through LED blink patterns. The most common codes we see are E7 (outdoor fan motor fault), U4 (communication error between indoor and outdoor units), and A3 (drain level abnormality). Our technicians can read these codes on-site and have the parts to fix most issues same-day.
Inverter Compressor Not Starting
Daikin inverter compressors rely on the PCB board to modulate speed. When the PCB fails or a capacitor blows, the compressor won't start. We diagnose whether it's a PCB issue, capacitor failure, or compressor burnout — and only replace what's actually broken, saving you money on unnecessary parts.
Water Leaking from Indoor Unit
Daikin wall-mounted units are prone to condensate drain blockages, especially in Singapore's humid climate. The drain pan can also crack over time. We flush the drain line, check the drain pan integrity, and ensure the unit is properly levelled to prevent future leaks.
Weak Airflow or Not Cold Enough
Daikin units with clogged evaporator coils or low refrigerant levels lose significant cooling power. The Streamer discharge feature can also malfunction if the unit hasn't been serviced regularly. We clean all internal components, check gas levels, and restore your Daikin to its original cooling performance.

Daikin Aircon Servicing FAQ
We recommend servicing your Daikin aircon every 3 months for residential units. Daikin inverter models benefit from regular maintenance to keep the variable-speed compressor running efficiently, which directly affects your electricity bills. For commercial Daikin systems like VRV, quarterly servicing is the minimum standard.
A blinking green light on your Daikin unit usually indicates a fault code. Common causes include a dirty filter (most frequent), refrigerant leak, or PCB board issue. The blink pattern tells us exactly what's wrong — for example, continuous blinking often means the unit is in standby mode, while intermittent blinks indicate specific errors. Our technicians can read Daikin error codes on-site and diagnose the exact problem.
General servicing for Daikin aircon starts from $50 per unit. Chemical wash starts from $80 per unit. Gas top-up (R32 or R410A) starts from $80 per unit. We offer transparent pricing with no hidden fees — visit our full price list for detailed rates including multi-unit discounts.
