Recomended brands?

Hi, I live in the northeast and have temps anywhere from 0 to 100 through the year. We have a unit in the basement that powers the first floor of the house, and it is a forced air AC and oil powered heating furnace. Both units are shot and we are going to replace the whole thing and convert to gas at the same time. (We also have another gas powered unit in the attic heating and cooling the 2nd floor but that one is working just fine and not going to be replaced). I have an estimate from one HVAC contractor and waiting on a few others to send me their proposals. I like the first contractor so far, but he uses Coleman and they don't really come up as one of the "good" brands when i google around. What brands of this type of equipment have the best reputations? What brands do you think are the best bang for the buck - not necessarily the #1 brand, but the one that is the best yet affordable at the same time?

Thanks
