Testimonials
What Our Customers Say
We recently had Deltech HVACR install ducted air conditioning throughout our dining, kitchen, and bedroom areas, along with a split system in our living area, and we couldn’t be happier with the result.
From start to finish, the team was professional, reliable, and easy to deal with. Their communication was excellent—they kept us informed every step of the way and were always happy to answer any questions we had. The installation process was smooth and well-organised, and they showed great attention to detail.
What really stood out was how neat and tidy they were. They took care to leave everything clean and in great condition once the job was completed, which we really appreciated. On top of that, their pricing was very reasonable for the quality of work delivered.
Overall, we highly recommend Deltech HVACR to anyone looking for quality air conditioning installation. Great service, great workmanship, and a stress-free experience
- Jakana Sheen
I was stuck in the hotel didn’t know what to do so someone recommended try alliance ! I rang and Marco got the refrigeration back on track for me - got me out of a real pickle !
Since then Marco and ebony have installed air-cons in both our hotels since and has done many a refrigeration job !
I can highly recommend alliance give them a go !
- Brendan John Mccoy
Great company to deal with. We had a multihead split AC system installed by Deltech. Marco is a good tradesman, well spoken, attentive with very reasonable prices, big or small jobs. The kind of small company that cares about customers. I would recommend hiring this company. Any issues they respond quickly. Very satisfied with Deltech.
