Hello I've been thinking of converting my boiler system for last 5 years. Hot water baseboard heat in a 2600 sq ft house + 2600 in basement. I have no complaints about the heat except I did have a leak under the concrete floor in basement to the baseboard. i would like to refinish the basement. My concerns are possible additional leaks in the future and no AC in the basement and stagnet air in the basement. The 20 year old airhandler is in the attic and doesn't cool the house that well. Only one return in the whole house for AC. I know I want ac in the basement. So i was thinking of eliminating both systems for a forced air system. What does everyone think?
