David from Toronto

We had our annual furnace and humidifier maintenance performed again this year by cosmopolitan mechanical services. The technician who performed the service, named Ather H., was excellent. He was very professional and polite, and obviously very knowledgeable in his craft. I really appreciated that he took extra time to explain all the checks he was doing on our system and for the simple recommendations he gave us on how to keep the system running smoothly (e.g. flushing our water lines with vinegar periodically). I would definitely recommend this company to others.
