Client Testimonials

Professional and Friendly

I had an emergency at home and was so scared to get ripped off. I was so happy that I found that Zazac on google. Sebastian was so professional and friendly. One of the best service I ever had. With a very nice follow up on his service a week after. I will for sure call him back and recommend him to my friends and family.

Great Customer Service

I have been using Zazac for a couple of years at my restaurant. Sebastian and his team are always quick to attend and very accommodating. The customer service provided is only upstaged by the quality of work. Always done right the first time, with very competitive rates. Completely recommend!

Excellent Work

Sebastien was my go-to guy when I worked as a maintenance manager for a restaurant group. If we had an issue with any of our HVAC or refrigeration Sebastien was just a phone call away. Because of his excellent work, I hired for my new company as well. I would highly recommend his service as he has never let me down.
