What our clients have to say

Arranged a service & got the best report on our air conditioner including photos, the technician explained the cost of repair and corrosion in the unit and that it would be better to replace the system, I went ahead with their recommendations for a new Mitsubishi Electric system and WOW its quiet and efficient. As for their workmanship I could not fault it, they arrived on time, even had their own vacuum cleaner and vacuumed up after they had finished, wished all trades personnel were like that! Keep up the good work Hills and will be recommending you.

Ruth King, Paddington

Very professional and meticulous, the installers were a pleasure to work with and we highly recommend them to everyone. They made sure we understood what was going on and instructed on the workings of the system installed.

Tanya Thu, Castle Hill

Great work guys on fixing the A/C temperature issues in my office, my office staff are more than happy.
Also the cleaning of the grilles WOW they look like new certainly will have you back to service it again.
