Being on the road in Perth's scorching summers has always been a challenge. After installing this rooftop air conditioner, it's been a game-changer. The quality is top-notch, and the price didn't break the bank. Kevin was incredibly helpful throughout the process, going out of his way to ensure everything was set up correctly. It's rare to find such dedication and service these days. Highly recommend to any fellow truckies out there.
We struggled to find someone who actually new what they were talking about Tuck knows his stuff and the AC we got for our camper is far better than expected we couldn’t be happier with our purchase.
Put one of these on our truck it cools really good can’t run it on full it’s to cold good problem to have. If you are looking for a air con these are definitely worth the money.
We brought this for our 3 Ton truck Kevan was very helpful all the way to the end very happy with it.
