What Our Customers Say
Trusted by Our Customers
“Zak is knowledgeable, detail oriented and does not just a functional but an aesthetically pleasing AC installation. Very happy with the Zak and the work. Zak always kept us informed and updated about everything going on which was very nice. I highly recommended him.”
Satish
“Installed multiple air conditioning units. Zak worked hard in both the design and installation phases to ensure that disruption was at a minimum, and the end result was as unobtrusive as possible. The latter mattered a lot to us, as with a larger install it would be easy for there to be cables all over the place. Zak himself was personable and knowledgeable, and I'm very happy with the end result.”
Jim McDonald
“Thoroughly recommend Zac from Optimum. Knowledgeable, helpful and his work shows his experience. Efficient and cleaned up afterwards, takes pride in his work. Gave solid, honest advice (not just the easy route, the quick fix). See photos of my old hot water cylinder and new.”
