We answer 24/7 — talk to a real Sydney technician, not a call centre.
Do you repair Hitachi air conditioning?
Yes — we repair and service Hitachi air conditioning across Sydney, for offices, venues, shops and homes. We're an independent ARC-licensed repairer using genuine Hitachi spare parts; we are not an authorised Hitachi agent unless expressly stated. Whether it's a wall split that's stopped cooling or a commercial VRF system throwing a fault, we diagnose to the cause and quote upfront.
Hitachi systems are well built, but inverter boards, sensors, fan motors and a slow refrigerant leak still fail over time. We read the controller, confirm the fault and fit genuine parts — rather than swapping boards on a guess. Where a genuine Hitachi part is on long back-order, we'll offer a quality manufacturer-approved equivalent and tell you exactly what we're using — your call.

Common Hitachi air conditioning faults we fix
If you're seeing any of these, book a check before the next hot spell — most are repairable, often same-day where we can.
Not cooling or blowing warm
Often low refrigerant from a leak, a dirty filter or coil, or a sensor fault. We find the cause first, then recharge to spec.
Fault code on the controller
Hitachi units flag a fault code on the indoor unit or remote — for example a pressure-protection code. We read it on-site, confirm the cause and fix it — not just reset it.
Inverter / PCB faults
The unit trips, restarts or won't start — frequently an inverter board, capacitor or fan-motor issue we diagnose to the part.
Leaking water indoors
Usually a blocked condensate drain or a failed drain pump pooling under a cassette or ducted head. We clear it and check the fall.
Indoor / outdoor communication error
A communication fault between the indoor head and outdoor unit — often damaged cabling or a board issue. We test the line and confirm the cause.
Won't restart straight away
Most splits have a built-in restart delay that protects the compressor — that's normal. If it still won't cool after a few minutes, book a check.
Genuine Hitachi spare parts & service in Sydney
We source and fit genuine Hitachi spare parts — PCBs, sensors, fan motors, capacitors, controllers and filters — backed by a 12-month parts warranty.
An air conditioner should be serviced at least once a year, and twice a year under heavy use — and many warranties require annual maintenance by a licensed contractor to stay valid. A regular service keeps airflow strong, power bills down and breakdowns rare. We can set you up on a schedule so it stops being a surprise.

Looking for air conditioning repairs, not just Hitachi?
We work on all makes and models — and cover the whole system, not just the badge.
Run a different system? We also service Mitsubishi air conditioning repairs and Fujitsu / General air conditioning repairs the same way. See all brands.

Rated 4.9 across 12 Google reviews — here are a few in our customers' own words.
"I bought an office with a dodgey aircon. And always knew I'd be up for 20kish to replace one day. For over 8 years these guys have helped me avoid replacing by regular maintenance. Quick response to call outs and always sending experienced, efficient, polite and tidy staff."
"The technician arrived when we were told… courteous and professional… took photos and wrote up notes… I received an SMS to let me know the tech was on his way. Everything… easy and pleasant from the ladies on the phone to the guy who came to our house."
"I can not recommend Chris and his team highly enough. I have used Chris for years… so much knowledge and professionalism… There is no job too big for active fridge and air. He's like the dinosaur of the trade… from Industrial to commercial and residential problems with air conditioning and refrigeration systems."
