Mom has a 50+ year old home with a fuel oil fired boiler to heat her house ( baseboard) and provide hot water. She wants to get rid of the boiler. Will not consider Gas.(anyway the nearest gas line is a quarter mile away) For hot water we will just put in a electric water heater. The problem is heating the house. She had Central Air put in 20 ? years ago. Is it possible to add Heat to that? If so, what would be involved?
Yes. What is the manufacturer & model of the air handler/furnace? Since this is a system that is over 20 years old, it is out of date, and costs her quite a bit, compared to newer models. Also, have you made sure that her home is properly insulated up in the attic, and all if most air leaks sealed at outlets/switch plates, windows & doors? As for the boiler, there are units that use outside temp sensors, that help to adjust the water temp, to make them a little more efficient.
As for cost to run the heating, she may be better off going with a heat pump, instead of straight forced air/central a/c for heating and cooling. The long term costs, along with rebates for 16 SEER plus systems would help for the initial costs. You can use http://www.alpinehomeair.com/ to give you an estimate of what it would cost to purchase a new system. There is also a program available that you can do a manual J, to help determine the best system for her home.
