I choose Frozone to service my ducted air conditioning system because of their great google reviews (and fun name!). Now I've used them, I can see why they have such a high score.

Very good customer service.

Very happy with the service I received from Frozone. Their tech was on time, courteous and knew his stuff. Best of all the result was exactly as I expected. Not the cheapest, but definitely a case of you get what you pay for (In a good way).
