Once again, the necessity of a service call provided an opportunity to meet another of the courteous and always helpful Harte Home Comfort staff. Don was fully knowledgeable, polite, and genuinely fun to chat with. All my inquiries regarding the service required were answered fully and only after Don was certain that I understood, did we move on. It is rare indeed these days to actually enjoy it dealing with a service company, but that is precisely what Hart Home Comfort is all about.
