Customer Feedback

What Customers Say About our Services Oved by number of customers throughout GTA!

We have been thinking about changing our 25 years old Ac for quite some time. Finally, last month we decided to change. We come to know about cosmopolitan through Lennox website.We got a very reasonable quote from cosmopolitan. Installation was done by the installer Dave. Very professional workmanship definitely deserves to be recommended.

If you need someone to repair your furnace or air conditioner call Cosmopolitan. We did and were very happy at the response and the cost a lot less than I had thought it might be. Greg gave me some good maintenance advice as well. We will call them from now on to do our pre season check and maintenance. It'll be well worth it.
