My current home is 1600 sq ft, 2 story double brick construction (circa 1939)located in Southern Ontario. Next year I am planning a 1100 sq ft 2 story addition. Currently have a NG boiler / cast iron rads. Boiler is 26 years old. No A/C in the house.
I am considering changing to a gas forced air system and removing the old equipment and rads. I do want A/C included when the addition is done.
My thinking to date on this is based on the following:
1.) cost to convert to FAG with A/C will be less expensive than replacing boiler and adding more rads and separate central a/c.
2.) FAG heats the zones faster than hydro.
3.) No more monster rads in the house
4.) Ability to improve air quality with FAG system
My existing attic is open and the existing basement will be gutted so venting to the first floor should not be too problematic. Existing second floor will most likely have to be accessed by ceiling vents.
Anyway has anyone had any experience with this sort of job? Do you think I am on the right track? Opinions and options about my plan would also be appreciated. Sure I would love radiant floor heat and skypack a/c but the lottery ticket has not come in, so please lets keep the $$ as a primary consideration.
Thanks in advance for your opinions and insights.
