Performance not Pressure

Hi, just had new compressor installed for my van's AC and with no book value amount of refrigerant to go by shop said they went "by pressure". Cools well but at hiway speed compressor cycles on about 17 secs then off about 17 secs. The off is very noticeable due to hi (90+) heat outside. I...

Re: Pressure Range

2 upgraded side mounted condenser fans and all is "cool". The first set of fans they put in were each 600 units of whatever you use to measure airflow and now they are each 1600. Mans greatest invention to date is A/C.

Re: Pressure Range

Incedently the system was cooling better just before I took it into the shop. With compressor bearings whining at speed I didn't use it but if I was at idle and turned it on I got cold air. Very infrequently I would do this at a red light when we had a heat wave 98 degrees. My previous condenser fan...

Re: Pressure Range

Thank you JohnHere. The van went from the dealer straight to conversion by 3rd party into a medical transport. It came with stock front AC only and along with a high top an aftermarket rear AC was added at which point the stock condenser at the radiator was disconnected and both front and rear units...

Re: Pressure Range

Not from a can. An auto shop is doing the work and checking the refrigerant level tomorrow. Understood about not as cool at idle. I know little about this stuff but with side mounted aftermarket condenser I still get cooler at speed I suspect because compressor is running faster. Thanks very much.

Pressure Range

Hi, So I had new compressor, receiver/dryer, expansion valve and duel fans (on aftermarket side mounted condenser) installed with evac. and recharge on my 2001 Dodge Ram Van 3500. System is not cooling as well as before the bearings went on my previous compressor. It does cool but not near enough. B...

Re: Low Side Recharge

I'm sure I used the 18 oz recharge kit properly emptying the canister and the AC was definitely cooling better. 1. I sure hope that "recharge kit" contained NO SEALERS. 2. One cannot really judge fill with just a low side gauge; doing that with low and high pressure readings at 1500 rpm i...

Low Side Recharge

Hi, I accidentally released a small unknown amount of refrigerant after which my car AC seemed to still cool at about the same level as before and remained that way for the last year until the current heat wave during which it still cools but not enough. I'm sure I used the 18 oz recharge kit proper...
