My rooftop AC tried to blow cool air and it sounded like the compressor tried to start but not very cool and I'm not sure the compressor is running or not.
Is there a way of knowing if it just needs recharging or replacing?
I had it into a RV shop for a new fridge and asked him to check it, after looking at it he said he'd be glad to replace it for me for only $595 plus $300 labor!
Just don't want to get taken to the cleaners just want to stay cool while working on BOB (Big Old Bus!).

You should be able to hear if it is starting as it is louder at first and then settles down. It's a sealed system so if it leaked, something is quite wrong. Could be critters nests in there, fan loose on shaft (maybe) or dirty connections (oxidized) on the push on flag terminals or a bad relay or delay relay or start capacitor or cob webs in the thermostat contacts.....all of which is reparable. If it's old and the compressor is shot, time for an new one. A VOM meter can tell a lot. Don't get shocked when working with capacitors so be carefull.

$600 for an AC unit doesn’t sound like robbery but $300 for installation sounds steep. It’s probably an hour or so for an experienced fellow to do the work.

I wish I made $300 \ hour!

Rick,

Your message is too general. To provide a good response we need to know:

1) Make / model / BTU rating of the A/C the RV shop is going to install
2) The hourly labor rate of the RV shop.

Regards,
Rob M.

John,
It does get louder when starting and then settles down and runs quieter, so it sounds like the compressor is running and the fan blows air just not cold air.

Rick Drummond

Rick,

John is very correct on everything, but I would suggest that you get up on the roof and undo the bunch of screws that hold the cover and peek inside. If it is something that can be fixed, you can probably see it*.

If the unit has lost its charge, they are not usually worth the cost of servicing as any leak now will still leak.

The labor quoted is not out of line, but it is outrageous. The quoted price is no deal, you can do that well on-line at any time. Do you have (or a friend with) a over head beam, a barn a tall enough or a tall tree with a stout branch? It is quite easy to sling up and lift the AC as they are not all that heavy.

* You may not be able to see a bad starting capacitor. You should be able to see it, but you can't see that is is bad. If it is bad, the compressor will typically make noise (hum) and then click out on the overload.

If you come back with more and clearer information, someone can probably come up with definitive suggestions.

If you decide to replace the roof AC, Jim K. has them in stock and is
currently running some kind of special. Give him a call before you pay
someone 10 times what my labor rate is. I am old and slow, but $300.00 an
hour??

Roof Air units have improved to where they are at least 20-30% more
efficient than the ones that came on the coach.
Always look at the value of the LOW PROFILE units as it reduces the
aerodynamic drag ,
The big bulky ones are less cost to purchase, buy you end up paying
for more fuel consumption when driving.
Wall electrical thermostats are nice to have.

My rear roof AC runs cold for a while then the air turns warm. Is this something I can charge with gas myself or do I need to take my coach to an RV repair place? Or?

Rick,

I sent you an email. Not sure what other's think, but it has not gotten above 35 degrees here in MN for month's. I don't think you can know if the A/C unit is working in these temps.

On most of these giant AC units there is sometimes almost a 15minute delay.The fan blows,then after a while the relay finally sucks in and starts the compressor.Some guys
run a f-ing screw down in the relay for an instant start up,but it can be almost 100 amps of power draw.That is why you never really try those AC's unless you have full
real shore power or the gen in good running shape.Try it again for about 20 minutes and see what happens.You will know when the compressor engages cause it will rattle the cage,no question.

Thanks all. First, I noticed this problem last summer, when it was hot. Second, I did hear the compressor engage and it blew cold for a while, then the air got warmer. I've changed nothing on the settings and it worked well before. I am just wondering if a neophyte such as I might be able to add some coolant to see if this works. If so, how is it done? If not, to the shop.  Thanks.

You would have to fill a roof air conditioner just like you would do a house room air conditioner or a house refrigerator.

First you should know that it doesn't use Frein R12 but rather R22.

They would cut the full line, braze or solder in a fill fitting. Evacuate the system. Charge the unit then crimp the line and cut out the fill fitting and then crimp and solder / braze the end to seal it.

Probably more than you want to try to do at home.

Thanks Emery. Greatly appreciated.  This sound like it is beyond my scope of tools and talents. To the shop when I get a 'round tuit'.

I have to tell you though Howard that if it is an original air conditioner you wou be better off putting the cost of repair toward a new air conditioner.

I've changed nothing on the settings and it worked well before. I am just wondering if a neophyte such as I might be able to add some coolant to see if this works. If so, how is it done? If not, to the shop. Thanks.

If you have to buy an air conditioner, do so BUT you can install it
yourself.
The wiring is already there, the hole is cut, and it will come with
installation instructions...all you need is a friend to help you get it up
on the roof . I don't know what you have for equipment so let me suggest a
2x12 and a piece of rope to slide it up.

Removal should be done first of course. You can practice your sliding
technique on the 2x12 before you have to deal with the 'good' A/C unit.

Just a thought!
