Kris looks after our air-conditioning service and we cannot praise this young man enough.

He is totally dedicated, doesn’t waste his time, not even time for a cup of tea! My husband and I believe Kris is credit to your company.


I want to say that myself and Vanessa have been extremely happy that we chose to get our solar installed by Simmark. All your staff have been very professional, polite and it’s been a pleasure dealing with Simmark. We based our decision to go with Simmark because of the good reviews online and you have lived up to your reputation. I’ve been recommending you to my in-laws for getting a solar system installed on their property.

I wanted to say how much I appreciated your professionalism when sorting out where to fit the aircon. You were more than helpful and prompt with emails during the initial quotation period and the young men who fitted the aircon were polite and business like in fitting the system.
So thank you very much.
