The Coit service person called in advance of his arrival; I appreciated this alert. Mr. Carlos was courteous, efficient and helpful with advice regarding my furnace, its filter, alternate filters available, and alerts regarding what I may experience when I first activate the furnace this season. This, too, was very welcome information. He competently answered my questions, as well as offering me price reductions on future services by Coit. I especially appreciated that he set to work immediately on the project, and indicated just how long the job would take. Thank you again, Coit, for your efficiency and professionalism.
