Air Conditioner Questions

[Jack and Liz Pearce]

Howdy, Y'all.
We have a pair of Dometic Penguin roof air conditioners that are
original equipment on our 1993 Wanderlodge.(The middle unit has been
replaced). That means they are at least 12 years old. The bedroom air
conditioner's fan is so noisy that Liz refuses to use it. The
livingroom air conditioner's fan is getting slightly noisy, too. And Liz
is starting to make unhappy noises about that!! [] []

There is 1/4 to 3/8 inch of play on the fan motor bearings/bushings.
The compressors APPEAR to be OK. The question is what is the average
life expectancy of the compressor? If it is 10 to 15 years, then I need
to replace both air conditioners. If it is 20 years or more, then I
need to replace JUST the fan motors, which is a LOT cheaper. Answers,
comments and suggestions would be MOST welcome.

Jack,
My practice is to replace fan motors until the compressors start making
noise. On my 91 I have only replaced one AC unit and we use them alot in Texas.
On My 78FC31 I eventually replaced both units, but not until they were on their
"last legs". I actually bought a Dometic 13000 btu at Camping Woreld on a
Special at six-months-same-as-cash deal and stored it until the last one finally
died!

I have replaced my 13.5 Dometic with 15.0 heat pumps. Cost was around
3500.oo for everything. Don't have exact price as will pick up end of the
week.
I replaced as units were 15 years old. I had noticed a low voltage light
even when on generator. Felt it indicated potential problems and the idea of
traveling to FL. with only two ac was not worth the risk.

It is my hope that the heat pump will allow a diminished dependence on the
PRIMUS... Just put new pumps on them and they work well but if I can use the
campground power to heat my coach, I don't have to burn my propane. I was
told to expect them to work well down to 35-40 degrees, after that we will need
and electric or propane boost.

My work was done at Foothills RV in Taylorsville NC. Bills out at 60/hr.
Dont know how that compares but its cheaper that Camping World at 100/hr.
