Hi, I am looking at getting an air conditioner (split unit) installed. I understand that their prices go through the roof during the hotter months and come down during the cooler months. My question is which months are the best to get them (having sweated through the summer)? Where to get a bargain? I found the unit I am interested on Billy Guyatt for $1.5k, where to get a bargain for the installation? Or will it be cheaper if I get supply and install? Thanks.
