And ladies, thank you for your help. Originally I was simply going to replace my Trane XE800 outdoor unit that died, but based on everyone's advice I've decided to replace the whole heat pump system. Here's what I'm getting:
Trane XL14i Heat Pump (3-Ton, R-410A refirgerant)
Trane Variable Speed Air-Tite Air Handler
Aprilaire 550 Humidifer
New supply lines
New electrical disconnect
New pump up legs
And I'm having a reputable HVAC contractor that I trust install the new system.
The only thing I need to decide on is the thermostat. I have to begin by saying I love toys. That's why I'm considering a Honeywell VisionPro programable thermostat. However, I'm a little confused. Honeywell apprarenty has several VisionPro models. Here are the ones I found (TH8110, TH8320, TH8321)
Which one is best suited for my Xl14i setup given its features?
I'm also starting to wonder about that Aprilaire 550. Should I upgrade to a better, automatic model? If so, which one?
