We recently moved into a new house, and I was debating on which contractor to choose for the job needed to be done at my place, and I had 3 contractors in mind based on friend referrals, homestars and other forums. It was apparent that homeowners on Homestars seemed pretty satisfied; and with 500+ postive reviews, i seemed pretty convinced. I was down to go look at their showroom/warehouse on royal windsor drive. I had to visit their place ( i actually visited their showroom/warehouse 3 times before deciding to give them my business :) ). Their store was quite far from where I live but with 500+ positive reviews, I had to at least check them out. Man! i gotta say Cosmopolitan has a huge and well organized office/showroom/warehouse, with a great team and large inventory in the back:) They had really nice people who very honest, knowledgeable, willing to work with my budget, patient and gave helpful advice and opinions. They placed great importance on providing exceptional customer service and were very professional in how they conduct their business. Afterall, I had chosen Cosmopolitan Mechanical for the job at my home, and was happy to give them my business. I ended up buying an Lennox comfort system from them (inc. furnace and air-conditioner), along with a humidifier, and the iComfort Wi-Fi thermostat. The installers/contractors were friendly hardworking guys who took their time to make assure everything was perfect as well as perfecting and levelling the concrete subfloor to install the air conditioner outside. They made sure that everything was satisfactory, cleaned up (parts of packaging and dust during the installation), and took away all the garbage. I am very proud with the job they did and would like to give them a token of appreciation from a 10 rating on Homestars.com.
