I'm in the same climate, and I had a Carrier system installed in Sept. I went with the Infinity ICS modulating furnace. I'd certainly second everything that was said about a good installer. My guy was excellent, bid and did the install himself. He showed me his licenses and continuing ed credentials up front. Very pleased. What I like about this system is it is nearly silent, and the DC variable speed blower saves a ton of $$. At the same time I had a whole house humidifier, and mid range Performance series Carrier AC installed. I went with this primarily out of noise concerns, as the AC is near a bedroom and also close to the deck. It's nice and quiet. The AC season is so short up here I couldn't Justify a more expensive AC. I think it is 16 .5 SEER.
I also had the Infinity thermostat installed and it is the only part of the system I don't really like... it works well, but is complicated, a bit more PC than Mac, and I'm a Mac guy. PM me if you need a good Carrier installer reference.
