hi Kenneth,

1 have 5 set of aircond (external and internal) which I can't recall which one of the compressor is faulty one.
All already been dismantled about 4mths ago.

1. iA - 15CT7B (iThink)
2. CU - C120 KH (National) (2 units)
3. HS - C1264SA4 (LG)
4. SAP - C91GA (Sanyo)

And I also can't recall the HP for each unit, but definitely have variation, not only 1HP.

Can you quote me installation cost for all 5 (I believe you know the HP for each of them).

For the piping, for 5, do you count as total 50 feet or 10 each? I plan for 2 back to back installation while the remaining 3 unit is about 10 to 15 feet between external and internal unit.

Please also include in separation line, if you have decent looking and performance, used internal unit. I'm considering to change all 5 units as well since the existing one is already yellowish (might trade in with you if ok).

if I want to call you direct, I don't have to write so long above. Some people are more comfortable to discuss via text rather than by phone la bos.

or u may pm me. thanks ya!!!

thanks kenneth

yes, I'm aware that those are old models. That why I'm asking in separate line if you could proposed indoor unit for all. Is there any?
