10 Air Conditioning Installation
Posted 18 July
Professional, tidy, honest, dedicated.
From the first contact Braydon was the most professional of everyone I approached. He sent a clear written estimate, asked sensible questions about the rooms, and gave honest advice on sizing rather than just selling me the biggest system. Braydon treated the install like it was in his own home with the attention to detail. Tidiness was spot on too. Everything was set up and configured before finishing, including wifi app and made sure everything was spotless. Absolutely dedicated to his work (didn’t stop on both days!) and turned up on time every day (which seems to be rare nowadays!)Verified reviewerJob location: SO3210 Air Conditioning Installation

Air conditioning installation
We were delighted with the installation of air conditioning by DiamondHVAC. The work was very professionally executed, it was a neat job which looked good. We were given a demonstration of how to use the system and it was clear that Brandon really knew his. I would have no hesitation in recommending him to anyone..Verified reviewerJob location: SO5210 Air Conditioning Installation

I was looking for a company to to install air conditioners in garden studios for my business and after speaking to Braydon from HVAC he came and installed an air conditioner for my customer. Everything went smoothly and he made a nice neat and tidy job of it. I have re-booked him in for my next Garden studio.Verified reviewerJob location: SO2210 Air Conditioning Installation
