You are right, just can't find that braze word.

Actually, the amount of work to install 2.5 or 3.o is the same, just the 3.o compressor may b heavier, and need to top up more gas as the piping size bigger, thus cost a little bit More

Your piping so long, sure expensive. Have you consider losses? 1HP at that length may not get any power when reach the blower.

My previous company, need 30000btu, but the compressor is 5 level below, total length is about 90ft and the HVAC expert advise minimal 36k BTUs, we end up getting about 40k BTUs and is just nice.

Sorry, I am not good in this. May I know what is BTU?

Uncle Google will give you more explain.smart phone is not fun to type.

Haha. They call it the 'pressure dip tank'. Checking compressor normally they hod pressure with bubble soap on the joints. Else, they will use more high tech machine. They call it the leakage checker.

Added on July 11, 2012, 12:41 pmNot necessarily. 3HP might not need a bigger piping size. Check spec. Also check your AC spec to see what is the standard piping length. Within this standard piping length, there is no need to add on the refrigerant. Do not exceed the max allowable piping length. Once exceed, you will have compressor oil return problem. Installation work for all 'residential' AC is the same. Work is the same. The cost difference is because of the piping length and type, and also the location of the AC. If it is difficult to access, AC installer wants higher price. For 'residential' AC, you do not need to top up gas if your piping length does not exceed the standard piping length. Take note and dont get conned.

Unless you are using single split packaged unit (cassettes, ducted, ceiling exposed), there will be no single split wall mounted that can allow piping length that long. So design the location wise. Putting the compressor at the top helps in your case.

do u hv warranty card?1+5 years warranty rite?i just called the sales person,he said mhi no need warranty card,just follow the receipt.....urs one same senario?just wonder...

Erm, I haven't gotten my air conds yet (just placed the deposit during the fair) as my house renovation isn't up to the stage where the air cond should come in, so I've no idea about it. But it sounds absurd to not have a warranty card. I think you should insist on that warranty card dude.

oic, tq.

Any advantage?

benefit is u just buy one aircond and use it everywhere....

the drawbk,i think how to dissipate heat

i m considering, hvnt buy yet

after moving here and there for few time you won't even want to move it. Is not light, and you need to put the ducting to blow the heat out. Not sure about efficiency, you may want to check.

If I at the hall, I drag the aircon to the hall. Than want to sleep bring up to my bedroom. Is it portable enough for me to carry it up and down in my home?

So where to blow the hot air out?

haha..sound so comical ...drag around the house..

I tot of getting one for dining..just in case..Coz of the location of the aircon at the living, by the time dining is cold enough, living may be a liitle too cold for comfort..

But where going to flow the hot air out? Need a long hose till the window?

My panasonic aircond is giving me problem. After ON few seconds - the blower slow down. The service guy said its the capasitor problem @ compressor there . he said its common problem for all airconds after 2 yrs + . Charge me rm 200 to replace it

i also dont know..i think it just went right out the back like our pc....havent survey

Use standing fan to redirect.
