Returning Customer "16 years ago your team installed 2 split system units in my home and I couldnt have been happier with the service back then. So when it became necessary for those units to be replaced you were the first company I contacted. You had the units in stock at a great price and within a week both units expertly installed. Your team installed both units without fuss even though I'm on a difficult site and consistent rain falling leading up to and on the day of install. I couldnt be happier and gladly would recommend your company to others."

"Geoff Lynam has been doing he air conditioning work for Rolfe Constructions now for six years, the first job that Geoff did for us was one that several other firms said couldn't be done and it is probably one of the best operating systems that I have been involved with. Geoff has done all types of air conditioning work for me from small split systems to a large commercial refurbishment job, ducted systems and even done some air conditioning work on a boat for me!
Geoff's knowledge of all these systems and products is second to none. Geoff has never in six years let us down on a job or not turned up when he says he will. I wold have no hesitation in recommending Geoff's work as I already do and have done to many people inthe past and will continue to do so in the future.
We have done jobs where an owner has insisted on using another firm and it has always ended in tears for our client, we do not have this sort of thing happening with Geoff. "

"Hi Geoff
On behalf my wife and myself, I just wanted to say a big thank you, for installing our Panasonic Ducted Aircon System.Your motto “We listen, then deliver to your satisfaction, guaranteed!” holds true and no doubt encapsulates your company's guiding principles. We can honestly say that you and your team "over delivered" - a rare quality in today’s business and corporate world.
We were impressed with your professionalism and advice and your recommendation to install an additional vent facing our computer area, works excellently. Please thank your hard working team of Mark, Mark, Brendon and Alex on our behalf . We would have no hesitation in recommending you to friends and associates.
We wish you and your company much success in the future.
Kind Regards"


"Hi Geoff,

I wanted to praise your guys for such a clean job. Very professional and very tidy. I like the fact that they cleaned after themselves. Not a common thing among tradesmen.

We could not try the main unit (missing remote but not an issue, shit happens), however the bedroom unit is awesome! It seriously runs no nothing. We monitor consumption thanks to the solar panels monitoring system.
The outdoor unit kicked in at less than 1Kw between 22:15 and 22:30 and then the indoor unit run up to 2:00am between 95Wh and 200Wh on a 15 minutes basis, including the normal house consumption. This means the indoor unit chews up less than those numbers. It is really less than a toaster!

I cannot wait to test the big unit :)"

Kind Regards

"Hi Geoff,
I would just like to say thank you for your services and that I could not be happier with the professional and tradesman like manner Dave, Mark and Brendon carried out their work.
My wife Wendy noted how polite and courteous Dave, Mark and Brendon were each time they needed to enter the house and this was much appreciated.
I my opinion, your business ethics and that of the guys is something you should be proud of.
We will have no hesitation in recommending your business to whoever if the occasion arises.
Again, thanks for your services and job well done."
Kind regards

"I would like to thank your fine tradesmen for the installation of our new Panasonic air conditioner. We had a serviceman arrive at the appointed time and after inspection of the old 20 year old LG unit, quoted a new Panasonic. Installation was next day far quicker than expected. Very happy with our new purchase and the professional installation."
Michael Baker

"I would like to thank you for finding a solution to a difficult installation on my pole home a few months ago. The Installer from the store I bought the air conditioner from refused to install it where I wanted as he could not think outside the square. You and your team did a
great job. I was so happy with your service, you were the only one I called to install a second unit downstairs. Once again great service from you and your installers, turned up on time & again did a great job.
Happy to recommend your company to anybody. Keep up the good work"

Hi Geoff,
Just letting you know that I have spoken to Kerri Leigh Gordon. Her 2 x Fuji splits and 1 x ducted were completed today.
She wanted me to let you know personally that she was so happy with the work that was done and the professional manner that it was carried out. She couldn't fault anyone. She said that they boys (AHC) were excellent - they were very prompt, careful and even cleaned up and vacuumed before they left. Everyone that she has spoken to in the office, and on site were very helpful!
She would recommend the installers to anyone!!
Geoff, please pass this onto the Mark and the boys..

Hi Geoff,
The guys arrived on time and they did a great job getting all the work done, they were very professional in their approach and have done a very neat and tidy job of the installation.
All good, one happy customer!
Thank you very much
