Very responsive to my calls for service.
I ended up having to replace my HVAC unit and now have a more efficient system. However, I would have appreciated the option to dispose of my old unit myself. Strangers showed up to my home and whisked my unit away which I could have received money for without a conversation with me. I was expecting Mr. Simpson to install my unit but he sent installers who I had never seen before. It would have been helpful to have known that someone else was coming to install other than Mr. Simpson. Lastly, upon Mr. Simpson leaving my home, I heard knocking in my furnace that was not there. I hope that that is not a sign of more work in the near future. Overall, very knowledgeable about HVAC related and reliable service. I would recommend with the aforementioned disclaimers.
