Today, I went to All Best. Below is the Mitsubishi's offer:
1) Inverter Sys 3 (including installation and piping): $2799
2) non-inverter Sys 3 (including installation and piping)$ 1899
Comes with 60months "workmanshhip's warranty"
But I read some bad reviews on the company... hesitating whether to buy from them or not.
Are there better offers now? I am only interested in Mitsubishi. TIA.
