I understand we will need seven air conditioning units on the two floors.That ' s what you think , yes ?   Yes . You could use five or six units.But five or six wouldn't be very efficient . I recommend seven .   And if we take the Decker units you suggested , what would the price be ?   Let me calculate the price for you . I can give you a 15 % discount if you buy the seven units.Let ' s see here . Your total would be 5929 dollars .   Isn't there any way we can get central air conditioning in this building ?   As I said , it is possible , but it would be much more expensive . I think it would be at least 12000 dollars to do a complete system .   That's too much . We need to use the separate units , I guess .   It's more practical , and the new units really are very quiet.Your customers won't even notice them .   So you say we can do it for 6000 dollars .   Yes , that's for the units.Installation would probably be another 700 to 1000 dollars.But it depends on the time spent , of course .   You mean installation isn't included ? I'm very surprised .   No , Ma'am . Installation isn't included.The price I quoted was just for the units .   In Taipei , you know , the company usually installs the things they sell.They don't charge extra .   I know that , Ma'am . But they would just raise the price of the units to cover their costs.Here in L . A . , installation is charged separately .   Yes , I suppose I should get used to it.But I'm not really willing to spend more than 6000 dollars for this.We haven't even opened yet .   I understand , Ma'am .   And the other company that gave me a quote on this said they could do it for 4000 dollars .   It's a question of quality , Ma'am . At that price , you would not get good equipment . I've been in this business for almost twenty years . I know what happens.If you don't get quality air conditioning now , you will just have to replace the system after two years .   I will tell you what I can agree to.If you can quote me a price of 6000 dollars , installation included , I can accept .   Well .   You do seem like a better company than the other one.So I am willing to pay more than 4000 for you . But I won't pay more than 6000 .
