It looks like I disagree with most of the other people here. Cost aside, I’d much prefer forced air (with a gas furnace) over radiators. Radiators simply take up too much space (and constrain the placement of furniture), especially in smallish DC rowhouses. We had radiators when we moved in (No central AC) and took them out when we renovated and added central HVAC. We couldn’t be happer with the decision. I have no problem with forced air heat. As long as your vents are properly positioned (in front of windows) you should be fine.
