I've had about 10 air-techs turn up to quote on a 15 to 18 kW ducted system and a 2.5kW split for my office
1. Quite a few of them have said they "won't install Daikin", "they're rubbish now", "make in China" etc etc are they truly no good any more or is this merely unprofessional tripe by guys who can't resell that brand?
2. The house is brick and tile with lots of insulation, 330 m2 but only 160 to 180 m2 is to be cooled. Will 15kW leave me wishing I went with 22k?
Thanks in advance.
