mine is MSY-GE10VA, cause my room is not too big

Yes my hitachi inverter 1hp at level 1 fan speed is already consider to hear to airfall noise.
The sound is something like si si si..
If used on quiet mode ke ke won't feel my room temp can cooling down at all.

So due to bad quality for hitachi product, i wont support it again, even buy York Y-Series Inverter still better than Hitachi like shit.

If you wanna install non-inverter 2.5hp don't go wrong, cause the huge size of condenser outdoor can easily vibration of your front door frame,
If the case is just hang up the top of door.

I can suggest install this model mitsubishi startmex inverter 2.5hp, for the set is around Rm2700~2900 sorry I'm forget already the actual price for without installed.

The electric bill is only cost you around same as 1.5hp non-inverter Aircon monthly Bill or less.
The R410a gas an inverter control is really make your living hall cooling & efficient.
Most of time you only need set to 25C or higher temp. Cause it is really feels comfort & quiet with easiy clean to access to fan blower.

my Mit Starmex 2.5HP inverter can cooling my whole of 24'x70' Single Storey House, then you said leh
even my 3-Rooms + Kitchen also feeling cold as well.

Mitsubishi Mr. Slim for non-inverter type and easy clean model
Mitsubishi Startmex for inverter type and easy clean model
Mitsubishi Heavy Duty non/inverter, just like York, panasonic, Daikin without easy clean.

so you prefer which one?

Hitachi really bad, noisy when airfall.. mistusbishi inverter so much quiet and easy clean somemore

today i wanna share my tip here
my aircond after installed and already up to 3 yrs of usage everyday still look new of internal coil.

look at "Daiso"

Once you feel the air flow won't be much stronger and remove the air filter to be replace a new or reused with after wash the filter to be reused back. That is what I doing that.

The works also same like the car inside of air cond filter and hide inside of below dashboard.

The solution you can kept clean on the coils and also lesses the water piping become stick more like Jerry and water leakage from the aircond drain.

From what I installed my aircond since is already had used 3 years long, but never ask the aircond service come to remove the whole fan coils for use tap water and flush with water on the aluminum coils else.

The solution to be kept clean on every each coils may good on air can be blowing out and like after wash the coils as a brand new aircond all the times.

Regarding the reducing of the airflow it is won't effect any issue of that. Unless your aircond type is non-inverter. Even without used air filter had already feels uncool at all.

I will effect the only cut down the cost of calling repairs Aircond servicing and aircond company.
Cause I not need them but my aircond still running like new.
Unless is no power or outdoor condenser already fully block by dust...
If on the outdoor unit had fully dust blocking and the unit you can touch it, you also can used some soften Brush to be clean out. Just becareful on the alum. coils do not bending only.

Some tip here, just becauseful when use tap water to be flush on outdoor on inverter type.
Because on the top panel had PCB and controller on indoor unit.
Do not flush direct on the alum. coils, unless you remove the whole unit down on the floor and slowly flushing on water only.

The rest you can use soft brush to be wipe or brushing out.
You also can operate when wanna do as brush the coils. Cause most of the dirty dust can be exhaust out much easier.

You can check the catolog before you install.

1hp on 6 & 9mm dia.
Some 1.5hp same as 1hp
2hp on 6mm & 12mm dia or 1.5hp same as 2hp
2.5hp should be use more bigger size on 9mm & 15.6mm cooper pipe.

Bigger to smaller should not an issue.
If smaller to bigger cooper pipe will be effect the compressor life.

aircond unit not increased price, but transportation increase on shipping in logistics fee to be everything price when up..

Last month asking is without install for Rm1450 with install = Rm1750.

But monthly you can save around Rm80-150 per unit of TNB bill.

R22 gas not so cold, if you compare to York R410a
Old technology for Daikin, no easy clean somemore

On paper maybe yes.
If you compare side by and you will get the R410a result as more faster cooling and more power energy saving.

R22 temp have to use 25 degree and below.
For R410a only need 25 degree and above.

Daikin is branded brand.

Mitsubishi electric inverter starmex are better.
Got easy clean that is what you needs

If you're the user then you will realised what I meant.

Cause I got my experience from R22 inverter changed to R410a inverter within a year..
