Yanny: Hi Amelia, just wanted to let you know that the new fan we had installed is fantastic. We haven't had any condensation since the day it has been installed!!
Amelia: Oh that is great news, I am so happy for you! How does it work?
Yanny: It pushes dry air into the house which dilutes the moisture in the air. Also a new kitchen fan makes the air circulate properly.
Sammy: Did the installer leave in the end? He was working late wasn't he?
Amelia: That sounds exactly like what we need! I am still mopping the windows every morning! 
Yanny: I know! he was here until about 10pm, but finished the job! 
Sammy: great!
Yanny: I'll give you his details so you can ask him for a free survey. See if he thinks you'll need the same. 
Amelia: that would be great ta
Sammy: I'll take his details too please! 
Yanny: No probs
Yanny had an air ciruclation device installed by a specialist and it turns out to be very efficient. Amelia and Sammy also have a problem with moist air at their houses, so Yanny will send them the specialist's details and he will verify if he can help.
