Asking contractor to replace 5 indoor units and 2 outdoor condensors and copper piping in/out. PVC pipe remains.

Is below a reasonable quotation?

I'm asking them to clarify the type of copper pipe, type of insulator and insulator thickness and warranty.

Any comments?

Anyone can help to comment if above is reasonable or too expensive?

I think its slightly on the high side.

Maybe $6.5k-6.7k can be done too w/o loss of quality.

Your quote is really expensive.

With your configuration, I would expect to pay at most 6k.

There is a local aircon installer who lists their prices online. Go google. It's way less than your quote with installation and other items thrown in.

Thanks Guys. Appreciate it.
