You guys are cool! Having installed our air conditioning about 5 weeks ago we are sat in complete luxury while it's 34 degrees outside. From start to finish with the advice given, the communication leading up to installation, the installation and the tiny snags we had afterwards everything has been 10 out of 10. There was even hardly any mess when they finished because they were using vacuum cleaner as they drilled! Based on my experience couldn't give them a higher recommendation.
We had 5 units fitted inside and 3 condensers on the outside with all the necessary connections.
