The best service you can rely on, Chung is the main person and his work is great. He actually knows whats he is doing rather than some guys who dont. For some reason our furnace acted up this year twice, first it was our construction guys causing problems and then recently something got stuck in the blower and the furnace decided to stop working, having small kid at home i have called and relied on Chung and he has come withing couple of hours to look at the issue and help it make it work.
I would recommend his service to anyone who has issues with furnace and he is 24/7 so will be available always when you call him.
Keep up the good work Chung. Cheers!!!!!!
