Contacted Air four for the first me after a positive referral and dont want to miss this opportunity to provide a wholly unsolicited opinion of your companies work , which i would be grateful to pass on to who ever might wish to see it .And that is just to say how pleasantly surprised we were from start tom finish., from the initial inquiries and specification through to delivery and installation in what seemed to me to be an impressively short time . All installers at my home went about their work in a thoroughly professional manner, courteous and obliging to a fault ,and like wise the two electricians

Very unprofessional by Adam.. A tradesman that comes with no ladder. But still charges you while he sorts out his stuff.
Pathetic

Very happy with the recent installation of air conditioning and heating at our home.
Damian and the guys are very knowledgeable and professional. The installation was hassle-free, and the company was very easy to deal with. Our in-ceiling cassettes look fantastic, and blend seamlessly into our period home. I have no hesitation in recommending Air Four to anyone looking for heating/cooling installation and service.

Had Airfour fix my home Airconditioning that most other local service companies could not fix . Found them to be very professional and the price that was quoted was less than all the other companies . Would highly recommend to others in the future
