Just got the news that my 12-13 yr old Rheem heat pump compressor went
out. Recommendation is that the whole unit be replaced and they are
working up a quote. I would gretaly appreciate some help with a
couple of questions.

1. Does the whole outside unit need to be replaced? Why not just the
compressor. What are the risks of doing that?

2. If I replace the whole outside unit should some of the inside unit
be replaced too?

3. Do I need to stay with Rheem or can I go with another brand without
replacing the whole air handler unit? Recommendations on manufacturer?

4. Should the air handler also be replaced? I run the fan constantly
to keep the temperature even and make use of the filter to eliminate
pollen in the house.

5. What is a realistic cost? I have a single unit for ~3000 sq ft
house. The current heat pump is a double fan unit. (Not sure of the
model, I can provide if needed)

6. While going to this expense should I have any testing done on the
house to make sure I have the best system?

Additional details: First couple of compressors did not last very long
~1 -2 years, but the current one has been around for 9-10 years. I
went out to look at the unit when it stopped working since sometimes
pushing the reset button got it started again. When I went to hit the
restart button, it was gone, looks like it disintegrated. Fan runs but
compressor does not. I have always had an occasional thumping noise
when the compressor started. Technician never seemed to be too
concerned about it.

Appreciate the help and input.
