Hydro air heat or not (conversion from steam)
In investigating AC solutions for our older home with single pipe steam heat, our HVAC rep strongly suggests to abandon steam and convert to hydro air heating thru central air ducts he would install. He believes we'll see a 30-40% gas consumption savings. Were not unhappy with the steam heat but a savings of this amount has peaked our interest. We would like to know from the experts if this is reasonable savings to expect? (We live in Nassau County, Long Island.) By what percent do electric costs increase with this sytem? Is this type of heat "nice" to live with?
Of course we could just keep the steam heat and add ductless units to cool the house. We want to make a reasonable decision to position ourselves for lower over all untilities costs, if it is worth it.
Looking forward to your response.
