I'm a new home owner and I'm having problems with a dual fuel Carrier system and I thought I'd start out by asking the simple stuff first: I hear talk of everything from 1 speed HP and 1 stage furnace to a 2 speed HP and 2 stage furnace. By reading the literature that was left with the house and looking at it I have no way to tell which this system is. I've listed the model numbers of the equipment. Can anyone tell me what this system is from the numbers? I don't feel like I can even ask intelligent questions unless I at least know this!
HP: Carrier 38QF
Furnace: Carrier 58DH
Optimizer II Control: 38CQ/HQ/RQ ?
Any help is appreciated.
