Need Advice On Id/aircon/built In Oven

[froggy 0]

This is very very strange. this is the third time I am posting this same message - hope it will appear this time!

To put everything in a nutshell, I am looking for a ID for my new 4room flat, and have narrowed down to ****, Lourve and United Team Lifestyle. Have read comments on **** and United, but not much about Lourve. wonder if there is any fresh inputs from anyone with experience with them? also comments on their workmanship, please

Secondly, can anyone advice if a fujitsu or mitsubishi heavy industries is better? i am looking for a system 3 inverter, and was recommended these two by the salesman.

Also on aircon, is it true that for single unit, there is no difference in power consumption in an inverter and non-inverter? Again, I was advised that there is no necessity to get a single unit with inverter.

Last, has anyone used an ariston built in catalytic oven? Is it good?

thanks!
