I just bought a new, [to me], very small one bedroom home which was built in 1956. The 80,000 [overkill], BTU nat gas furnace was said to be overkill by my home inspector, probably 30 years old, and probably won't last another year. He said that a new hi-efficiency
40K BTU furnace would do for this size home. When I asked about incorporating central air, he said the electric service coming into the home wouldn't handle it. I only have 60amp coming into the home from the street, w/100amp breaker box. As you might see, I have a couple of problems that I want to fix as efficiently and inexpensively as possible. Where should I go from here? Will 100amp be enough? How much could I expect to spend to have this work done, including upgrading the elec service to the home and purchase and install of his recommended furnace w/or without central air?Thanks
