If is Condo, a 1.5hp. Terrace 2hp.

Yup terrace & landed house. Any recommendations for 2hp aircond? Since using at living room won't run long maybe 3-4 hours only. Should I get inverter or non inverter unit? Part & gas for inverter more expensive than non inverter right. Most shop I survey say's better get non inverter because cheap to maintain & and for no long hour usage.

I just found out the outdoor unit of my Hitachi aircond is not turning on. The unit is about 3 years+ old. If not mistaken the outdoor u lnit has 10years warranty.

Anybody have experience on the warranty claim? Just call any aircond service and pay the service fee to get them to help claim warranty?

Thanks in advance.

If it's still under warranty, just contact Hitachi customer service.

My experience .....

The cost to claim warranty can buy a new outdoor unit.

You can only engage their authorised service technician. Call customer service for the lists.

The warranty covers only the faulty compressor. Labour charges chargeable for replacement. Other minor parts like capillary tube etc are chargeable including refrigerant by the manufacturer.

The authorised technician labour is a separate charge to dismantle and reinstall the unit plus transport.

If the compressor is not faulty, checking fee is payable to manufacturer plus the technician labour charges.

Call the authorised technician and NOT any technician. If is other problem, he can repair at site.

if it turns on then shut down ... possible dirty clog fins .

if i dont turn on at all , possible the cap is faulty , so cant kick start the compressor.

not sure if hitachi has inbuilt diagnostics .
if have check the ERROR codes on the remote.

Thanks for the responses. The service center hotline is not open on weekends.

I checked again and heard some whirring sound from the outdoor unit but the fan didn't turn on. Initially the air felt cool but after a few mins it was blowing warm air.

Anyway, best to get a qualified technician to check it out. Any idea how much a new outdoor unit + installation would cost? If the difference is not huge, might consider getting a new one instead.

It is a 2HP R32 non-inverter unit

If you can get hold of an authorised technician during mco, is better. Otherwise find a good technician and request him to check. If indeed compressor issue, then you decide whether you want to claim or buy a new one.

If it is other problem he can solve then get it done.

A 2hp outdoor non invertor average should cost around 1.5k+ .

Hi, all sifu.. looking for recommendation for AC, currently using daikin inverter with R410a for my condo. all around 6 years old.

my aircond had previously ? leaking gas problem since 2 years .. require frequent top up past 2 years, check by multiple technician, they say the gas pipe no problem, today the other technician mention the indoor foil is not good (spoilt? - may lead to leak), with some mold.


any recommendation of model? most importantly energy saving as the usage of AC in my home is very heavy.. as usage is 24/7.. looking for something reliable.. prefer standard / slightly higher tier.. but not the most premium range. any brand should do.

looking for 1HP and 2HP ac.. i may need to change phase by phase

usually the technician will charge for dismantle the existing unit too and installation ?

Pana is a reliable brand. Been using for many many years with minimal problem except for 1 lemon unit. All my current units are more than 10 years and non invertor.

For installation and dismantle, some will charge extra if is just a single job.

Hi guys,
Can enlighten me about inverter? It been mentioned but still dont really get. Sorry...
I have 2 rooms, 1 for TV 4x4m 1pk and 1 for work 4x5m 1.5pk.
Both standard AC now.
AC will only On when are occupied. Usually will blast and set lowest temperature.
In this case, does inverter have it usage?
Thank you very much.

Invertor technology is supposed to reduce electricity consumption as stated in the brochures. How it actually does, it depends on user applications. Info on brochures are tested in manufacturer environment and it differs from actual site.

AC hp must match room space volume, maintenance, usage duration, other electrical appliances in the room, number of people using the room and location..whether condo, landed or west facing unit.

So if any of the few variables are not satisfied, then it wont work.

Inverter air con will only save your bucks when the space is totally enclosed (no leakage) and the capacity of air con is sized accordingly based on the space.

It tend to tweak the compressor speed upon the temperature is achieve, hence, reducing power. If the space is frequently leaking out cold air or the air con is undersized, the compressor will run full speed all the way, hence, equivalent to non inverter unit.

Hi guys sorry if this question has been asked before.

I'm planning to get a Daikin 1HP aircond for my computer room. The room dimension is quite small around 9x9 feet. Do I need to get an inverter one or the non-inverter will do just fine. Do I save a lot more with an inverter for the 1hp?

normally using aircond around 3-6 hours continuously a day.

Just buy the standard non invertor. You wont know whether you will save tnb bill with invertor cos there is no comparison in actual situation.

Depends on set temperature as well, if always set AC below 24 DegC, then best to get Non-Inverter as the AC will keep running at high power and unable to achieve the set temperature within 3-4hours, if set below 24 DegC.

So far all my bedroom inverters are set at 24 - 25 degC and we use it conjunction with ceiling fan to spread the cold air around

Please be aware that the mainstream inverter aircons are normally categorised as higher end model than the standard non-inverter variant.

The cooling capacity is also higher even the compressor is running full speed.
This means even the inverter dynamic speed feature has not kicked in yet, it already consumes less power than the non-inverter lower end model.

The inverter tech is already in the market for many years and this is NOT the only tech for saving electricity in aircon.
If your aim is to save electricity, an inverter aircon is the one to go regardless of any environmental factors if we are comparing the same HP units.

Of course, the next steps are to consider the correct size unit, house sealing and etc.

So you are saying if Inverter set at Fan3 and 16 degree for 8 hours straight is still save more electricity than Standard non inverter?

I am using Sharp Eco-Inverter (The earlier model since 2015) and working fine with no issues at all.

J-Tech Inverter Build quality is cheaper compared to the older Eco-Inverter type and particularly our 2HP unit has been having random power issues after power failure. I have another 1HP J-Tech Inverter which has no issues at all (1 year+)

The 2HP J-Tech inverter will refuse to switch on (totally Dead) until few hours later after a power failure. Haven't been able to diagnose the cause; as it is out of warranty now (1 year +) and by the time we want to get the repair guy in, it starts working fine and dandy again.

All our Sharp AC run more than 12hours a day during this pandemic.

If you want to set the AC at 16degC better get non inverter, the AC will never be able to achieve this set temperature in a normal sized bedroom.
