Ok, I have an old forced hot air system(not that old), but I have a daughter with asthma, and the old ductwork carries dust and mold that could give her a hard time this winter.
I want to go forced hot water, but I am debating gas or oil. We have gas in the house, our hot water and stove are gas(I refuse to give up cooking with gas), so supply into the house is not a problem. And the gas company will put up a good amount of money for equipment if I switch.
But with security issues with gas, I have to wonder if that will drive the price up. But I guess the pros and cons go back and forth.
I know gas burns cleaner, and I don't have issues with the dangers of gas, but I feel more secure with oil(I feel I could always get something cheap to burn in it).
The last option I have is to have someone come in and clean the ductwork and think it over the next year.
