Replacing 2003 AS AC Unit

OK, looking to replace the AC unit on our 2003. Looking for 1 unit, 15K with heat pump. Lots of question to see what the group thinks in regard to what unit to bu and why.

1: Thermostat wiring.

2: Drainage hose and connection

3: nbrand

1. Which unit do you currently have?
2. Replace with same manufacturer and reuse current wire harness.
3. Connect to existing drain lines.

Dometic owns almost all of the industry and they have decent units.

I just had to add the drip cups to my 2005 AC so I had to pull unit if you want to read through my post a couple below yours. Regardless of the unit you go with you will have to pull the old drip pan assembly from the roof and scrape up all the dicor that bonded it to the roof.
1. If you don't have a thermostat now you will have to fish a wire. My 2005 only has the roof controls.
2. Drainage should come off the streetside of the current unit. Find a 1/2' elbow to help make the connection to the current drain hose so it does not get kinked.
3. I would go back with a Dometic low profile unit with heat strips which is probably what you have now.
