Common Hitachi faults

Hitachi playing up? We'll find out why.

Most Hitachi problems start small: a blinking light, a drip, a remote stuck on the wrong mode. These are the faults we fix most often, and what usually causes them.

Blinking lights or fault codes

A blinking light on the indoor unit means it has logged a fault. We read the code, find the cause and fix it, from sensor faults to communication errors between the indoor and outdoor units.

Not cooling or heating properly

Weak airflow or lukewarm air usually comes down to blocked filters, dirty coils, low refrigerant or a failing part. We test the system and tell you exactly what’s wrong.

Water leaking inside

Drips from the indoor unit are almost always a blocked or badly graded drain line. We clear it, check the fall and stop it happening again.

Remote or controller problems

A unit stuck in the wrong mode, or one that ignores the remote, may only need the settings corrected, or may have a failed receiver board. We check both.

Not sure what's wrong? Book a check and we'll tell you.

When to service

Service your Hitachi before summer.before winter.

The best time for a Hitachi service is just before you need the system most. A check a few weeks ahead catches a tired part or a blocked drain before the first heatwave or cold snap, when everyone is calling at once.

Each season’s service focuses on the mode you’re about to rely on, and you get a written report at the end.

Get the clarity you need

What does a Hitachi air conditioning installation involve?

We check the room size and layout, confirm the right capacity, mount the indoor and outdoor units, and run the pipes, drain and power. You get a fixed price before any work starts.

How often should a Hitachi air conditioner be serviced?

Once a year for most homes, ideally just before summer or winter. In between, clean the filters yourself every few weeks when the system is in heavy use.

What do the symbols on my Hitachi remote mean?

The main ones are the mode symbols: a snowflake for cooling, a sun for heating, a water drop for dry mode and a fan for fan-only. If the unit won’t heat or cool, check it hasn’t been left on Dry or Fan. The manual for your remote lists the rest.

My Hitachi air conditioner light is blinking. Can I keep using it?

A blinking light means the unit has logged a fault. Turn it off at the remote, wait a few minutes and restart it. If it keeps blinking, leave it off and book a check.

How long does a Hitachi service take?

A split system usually takes about an hour per indoor unit. Ducted systems take a little longer, because we also check the ducts, zones and controls.

Which Hitachi systems do you work on?

Split, multi-split, ducted and ceiling cassette systems, along with larger Hitachi commercial systems.

Should I repair or replace an old Hitachi system?

If the system is under about ten years old and the fault is minor, a repair is usually worth it. For older systems facing a big repair, we’ll give you both prices so you can decide.

Are you an official Hitachi service agent?

No. All Good is an independent heating and cooling company and isn’t affiliated with Hitachi. Our licensed technicians service, repair and install Hitachi systems across the range.
