I am currently in the process of renovating a 2,000 sq feet house in Long Island, NY. I have currently heating boards and separate air conditioners. I was planning to install central AC, but my contractor suggested that we could get rid of the heating boards, since they are not in top shape and install Central heating/AC system. I have oil furnace. Any suggestions if this is the right approach or I should just replace the heating boards and add Central AC. Thanks in advance.
