We had some furnace problems in the fall where we needed the igniter replaced and the motherboard had been acting up and sometimes the blower would not turn on. We called Cosmopolitan Mechanical Services and they sent out Khalil to our house. He was very nice and quick with his repair. The furnace was older and the motherboard required a complete rewiring to be compatible with the furnace and Khalil did a great job (being an electrical engineer I'm quite picky about wiring jobs). I would definitely recommend them to anyone with HVAC issues.
