Ok so we've been very lucky in that our Carrier Air heat pump has lasted this long. It's still working but making a horrible noise. We're pretty sure it's vibration in the condenser.
Ok so SEVERAL issues in replacement:
We've seen that you can buy an adapter kit for the carrier to coleman AC. We may do this but have found comparable complete systems for what it would cost to do the adapter kit with just replacing the top unit. Another reason that we'd rather replace the whole thing is the fact that the remote that controls our carrier (and I assume would be responsible for controlling the mach one too) is no longer made. There is only ONE on e bay (that works our heat pump as well) right now and it's going for $140 with several bids. What happens if we do the swap out with the top unit and keep our control board and heaven forbid loose our remote
or it stops working (you should see how old and gross the remote is!)
So obviously we have no wall controlled thermostat and all the units I've found require that for ducted systems (I am seriously cursing Carrier AND carriage right now) So does anyone have any way around this?? I would assume trying to install a wall thermostat would be very costly.
Ok yet another question. When we replace our air will the new unit be able to control the furnace like our current one does as well? All of these are probably silly questions and there are cut and dry answers to it. I just hope someone can give them to me
