We had our first furnace maintenance service from Ather, Senior Service Technician, last week. He was very professional and prompt with his work. He explained to me how the furnace works and what he was checking to make sure it is a great working condition. He mentioned that some sensor in the furnace was dirty, which is the most important for the furnace. We are very happy that we had this service before it got worse or otherwise it will cost more to repair! He also educated us about carbon monoxide detector and how we can maintain the furnace by checking filter occasionally, changing it, and clean the steam drainage pipe with vinegar, which we've never thought of! Thank you so much Ather Hasan for your service!
