DO NOT USE THESE GUYS!!!! Built a home with a company which has been an absolute nightmare and their sub-contractors are Dandy Air, which put in our refrigerated air con.. I have been living in my new home for just over 18 months and guess what, have not been able to have it working!!! Dandy air staffs are the most unprofessional and unreliable trades people i have come across. I have been trying to get them out here again for the last week and still waiting on issues that should have been noticed and fixed 12 months ago when they did come out. I have leaking gas and loose ducts etc etc. Absolutely awful company to deal with!!!!!!!!!!!!! I wouldn't even give them half a star!!
