What Our Customers Say

I will be brutally honest, your product is absolutely fantastic and I would/will recommend your services to anyone. Your installers were better than fantastic, they deserve a pat on the back for their committed work ethic. You would be hard pressed to replace such committed and professional tradesmen should you loose one of them. My son will be in contact with you in the near future as he is impressed with the system you installed at our house.
Steve & Kerry Clements
Thank you so much for all your help and assistance with the electrical and air conditioning to our new home. From the get go, your advice was invaluable to both myself and my wife. When we were designing the systems you both treated it like your own homes, and gave us invaluable suggestions as you took the time to ask us what our lifestyle and family needs were. So you both developed with the help of your efficient staff a truly magnificent result that has gone far beyond our expectations. The lighting, power, security, intercom, air conditioning zones NAILED IT. Your staff with special mention to Tom Bell and the whole of your team of tradesman was exceptional, their courtesy shown to not only ourselves, but also other trades and our supervisor should be commended.

Thank you J&M Costa, We are writing to let you know how very happy we are with the Actron ducted air we had installed. The quality of the unit is superb but the level of customer service as been nothing less than 5 star. Craig showed an exceptional level of professionalism and a great level of understanding of his products which made our decision of which company we wanted to install our ducted very easy. The installation of our ducted was very smooth, the boys were very professional, thorough and friendly. We were very surprised and pleasantly impressed with the after care phone call. Thank you again, we are extremely happy and would highly recommend J&M Costa.

Kevin & I just wanted to thank you on the installation of our ActronAir Air Conditioner. We are very pleased that you advised us on this unit with the added zone areas. It is so easy to use & as you advised us we are only using areas that we require & not cooling rooms we do not need, which is a bonus. I'm sure in the long term it will be most beneficial cost wise. I would like to thank your staff on the installation of the air conditioner. They were courteous, professional & considerate. They explained any queries I had about the air conditioner and when they left all rubbish was taken. You would not of known they had been at our house. Although it is only early days with our new Air Conditioner we are more than happy with it I would have no hesitation in recommending J&M Costa and their staff
