Ather has come to my rescue! I found Cosmopolitan via Homestars and purchased my furnace and AC from them in 2008. I have had Ather maintain my HVAC now for a few years, and whenever my HVAC needs maintenance or has a problem, I always specifically ask for him and him only. Ather comes in a timely manner and fixes everything. He always calls to let me know where he is and his approximate ETA. He is so kind and considerate! My furnace has been working sporadically so Ather came to diagnose and fix my furnace. He went through each part of my furnace step by step with care and detail...he is my furnace doctor! He shows me what he is doing and explains to me what is going on with my furnace. I can tell that he loves his job and knows what he is doing, and I love it that he is my furnace technician! Thank you Ather for doing such a wonderful job, AGAIN!!
