I would like to put a larger blower fan in for the air conditioning is it possible to be done. How do I access it and how do I totally remove the heat pump.

Not sure which brand you have, and I don't think you can change the blower, but a good cleaning may help. If your unit drops it's output directly down to the coach, you need to take off the bottom grill. THere will be 4 large, long screws in the corners of the duct that are holding the unit on the roof. Pull them, go on the roof and you can work the unit up. You'll need to remove fiberglass cover, power cords, thermostat and perhaps a few other wires and/or lines. For example, my Tiffin has a condensate drain line through the roof to the front and rear caps.

If your air dumps into a roof duct setup, you need to go on the roof, pull the fiberglass cover and get at the 4 screws that way. 2 are easily seen, but on mine, 2 are behind a piece of galvanized metal that needs to be bent up to get to them. It's sealed with sealer and/or foam (tape). You should also be able to see the fan from the top.

My friend has a 2007 Alfa and he had low fan pressure and he found that Alfa didn't cut a discharge or return box out right . He has a rear basement heatpump. Opened it up and hasn't had trouble with it since. Look it over close. Yours might be the same. Can't get a hold of him now.

Heat pump

Basement air or roof top air makes no difference. The heat pump is not something that can be removed. It is actually the Air conditioner running the refrigerant backwards by use of a valve that changes the direction.
