My family spoke to Steve, Niwash emailed a quote on Tuesday, was competitively priced, installed and running by Friday 1130am. Installers cleaned up after themselves! So good they took all the old parts including the remote and holder which I had wanted to keep but forget to tell them! Otherwise, will definitely use them again! Thanks!

Very easy to deal with. No mucking around. Got a difficult job done with a minimum of fuss and back up came when called for. Now we are cool thanks to UB Cool!

By far the worst company I have used. Disgusting customer service by the owner, Steve, and even worse treatment of women. I will never support this behaviour, there are far better local businesses worthy of my business. It's not worth the hassle, they are nice to your face when you're spending money, but completely different when it comes to after-sales 'service'. The owner has become far too arrogant for his own good, and openly refuses to come out to warranty jobs because he "doesn't need the business", regardless of consumer rights - which he has no interest in. If you use this company, just

Spoke to Steve from UB Cool, his boys installed a massive outdoor unit. They left the site looking immaculate and did a bloody good job.
