The indie shop and the dealer both said that it could be any number of things and they could run diagnostics, but both recommended replacing the entire compressor assembly and not just one part, since in their experience replacing a part was a lot of labor cost and didn't always fix it or last that long. They said to just replace the compressor, if that's what I decide to do. Of course, it's more $$ for them, but I do trust the advice from the indie shop (certainly more the the dealer).

You'll know right away if the system is low. The compressor will start to cycle, quickly at first then should taper off as more refrigerant gets in the system.
That's good advice and info. Thanks.

You can shim a clutch, I had to do that on my car as the clutch started to wear.

I replaced my wife's compressor and accumulator for around $150 including recharging it.

Yes, a little too much refrigerant can cause problems. R134a systems aren't tolerant of overcharging.

Those DIY kits have crappy gauges but if you're careful, try that first versus slapping on a compressor, which probably isn't bad anyway (big ticket repair item for the shop). Don't follow the pressure chart that comes with the kit. You'll end up overcharging like crazy, especially on a Honda. On an 85F+ day, these cars like to stay around 30-35 PSI on the low side.

Add a little bit of refrigerant in at a time, listen to the compressor (should constantly run when the blower's on high on a hot day), make sure the cooling fans run, and watch the vent temps with a thermometer. On a 85+ day, the vents should get down to the low 40s.

No, it won't cause any problems. Slightly reduced cooling maybe.

Great advice! Thanks!

The fittings on auto-AC are, thankfully, wrench-tightened. So, I would try the DIY and tighten every fitting on the AC-system.

Receiver-drier would be a good idea, but technically and legally you would need to get the system evacuated to do that. Now if you put a guage on your system and there is no pressure, no refrigerant should come out when you open it up.

Don't make my mistake, just do the evac and recharge, off of the machine they use. You ac line pressure will tell the mechanic what is wrong.

I would stay away from dealership , look for a shop that only does ac, with that grey machine.

I just went in circle of mis information with 2 mechanics, and was looking at changing parts, but that one guy said, "put it through the machine, no second guessing" viola,ice cold ac.

If there is a major part like a compressor, buy the part on eBay, have indie shop install, but will need to vacuum and recharge again.

Those diy can fills is a waste if you need to vacuum the lines.

YouTube has videos for everything nowadays, do a search.
