About Hitachi servicing

Why Hitachi owners book us

Hitachi aircons are known for quality and durability, and are popular in both HDB flats and private condos across Singapore. Hitachi's Frost Wash self-cleaning function is a useful feature, but it cleans only the coil surface — it doesn't replace a full professional service of the filters, blower wheel, drainage, and compressor.

We service all Hitachi models including Frost Wash, Premium (RAS-X/S), Standard inverter (RAS-E/EJ), multi-split, and older non-inverter units. We take before-and-after photos of every job and flag anything unusual — worn parts, unusual readings — before doing additional work.

We take before-and-after photos of every unit and send them to you. If we spot anything — low gas, cracked drain tray, unusual compressor readings — we flag it and quote separately before doing any additional work. See all aircon services →

Common issues

Common Hitachi aircon problems we fix

Hitachi aircon not cold

Most often a dirty evaporator coil or low refrigerant. Hitachi Frost Wash cleans the coil surface with ice, but deeper mould and compacted dust still need a chemical wash. If the unit is blowing air but not cooling, start with a chemical wash.

Hitachi aircon leaking water

Usually a blocked drainage line — cleared as part of every standard service. Hitachi Frost Wash units may sometimes leave residual water in the drain tray from the self-cleaning cycle; if the drain is partially blocked, this overflows.

Hitachi aircon smells musty after Frost Wash

Frost Wash cleans the coil surface but leaves residual moisture that can encourage mould growth between cycles. A chemical wash fully clears mould from the coil, blower wheel, and tray — recommended once a year even for Frost Wash units.

Hitachi error codes (E or F codes)

Common Hitachi error codes (E01, E03, E07, F01, F03, etc.) indicate sensor, compressor, or fan issues. We diagnose on-site and advise clearly before doing any additional work.

Ask on WhatsApp →
How much does Hitachi aircon servicing cost in Singapore?+
$50 for 1 unit, $30/unit for 2 units, $25/unit for 3 or more. Chemical wash: $60 for 1 unit, $50/unit for 2+. Includes before-and-after photos, shoe covers, and compressor check.
Which Hitachi models do you service?+
All Hitachi aircon models — Frost Wash, Premium RAS-X/S series, Standard inverter RAS-E/EJ series, multi-split, ceiling cassette, and older non-inverter units.
Does Hitachi Frost Wash replace professional servicing?+
No — Frost Wash cleans the coil surface with ice, but it doesn't clean the filters, blower wheel, drainage system, or run a compressor check. Professional servicing covers all of these. We recommend a full service every 3 months and a chemical wash every 6–12 months even for Frost Wash units.
Why does my Hitachi aircon still smell after a Frost Wash cycle?+
Frost Wash cleans the coil surface but doesn't remove deep mould from the blower wheel or the drainage system. A chemical wash reaches these areas and includes a mould treatment — units are typically odour-free within 30 minutes.
My Hitachi is leaking water after a Frost Wash — why?+
Frost Wash produces condensate water. If the drainage line is partially blocked, this water overflows the drain tray. A standard service clears the blockage. We'll also check the drain tray and pipes while on-site.
