Dear Bill

How happy are we?

We are absolutely delighted with the efficiency, professionalism and courtesy that your team installed our ducted air conditioning system today at Blackheath. Josh, Aidan and James were superb!

Thank you Bill and your team!

Please thank Bill for providing an excellent service & for doing a great job – he & his team are to be congratulated.

I wish to compliment the two young men who attended our home this afternoon to service our air conditioning systems. They in fact typify the others from your company in that they are friendly and respectful men who willingly, patiently and gently explain whatever we need to know. It is so reassuring for us in our 70’s to feel so comfortable and reassured when they’re here.

I will certainly pass on my experience to anyone needing professional work done.

Tony Strahan

We were delighted with the speed and efficiency of both the pre-sale service we received and the installation. The process went like clockwork from start to finish. Bill and his staff were a pleasure to deal with. The ducted Daikin air conditioning system is terrific and we couldn’t be more impressed.
Tammy & Alan Schwarz

Josh has just left having serviced my airconditioning unit. It must be 10 years ago that it was installed and it has worked perfectly ever since. Josh did a brilliant job, cleaned up after himself and was very friendly. I would be happy to give a recommendation should you ever need one.
