Ok I have a 1995 Honda Civic EX with the 1.6 liter Vtec motor. The A/c blows hot air, I can hear the compressor engage and the motor idles up. I recharged it with that stuff form Walmart and it blew "cooler" air but not cold only briefly and then went back to hot. Current weather here is about 95 degrees. I suspect that it just needs to be evaced and refilled. It seems to hold the PSI that I recharged it with. I think its just the coolant is too old. No obivous signs of leaks. and the air temp does get cooler (not as hot) when I switch the a/c on so i think the door that seperates hot/cold is working. Any thoughts?

I'm afraid your wrong on nearly all of your assumptions. The age of the refrigerant means nothing. leaks are not visible since refrigerant is an oderless, colorless gas and since it was cool and then warmed up, it likely is leaking somewhere. Your best bet is to have it professionally tested and leak checked. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

Yes, leaks are the reason. A good system will never need to be recharged. If it does, the leak should be repaired, not just recharge the system. That will eventually lead to a compressor failure from lack of lubrication. You really need the system looked at professionally because leaks may not be your only problem at this point. Most places will diagnose and leak check it for under $40. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

Honda Dealership wanted to charge me 150 to evac and recharge. Plus any diagnostic work. I just went out and checked preasure since my last post and with the engine runnning and the a/c OFF on the High side ( i think, the one with the blue cap, the smaller one) i have 35PSI but when I turn the a/c on full blast, i hear the compressor kick in and the PSI goes to 0.....

I own a shop and I charge $24.95 for a check. You don't need the dealer, just a shop that does a lot of A/C work. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

Youngblood; You mentioned high side. I haven't done any A/C work since the old R12 days, but I do know that you never, ever, want to try to charge the system on the high side. Could end up with a can blowing up in your hand. Follow Hammer's advice. This is not a job for a novice. Low side pressure on the R12 systems with the compressor engaged, was in the 35-40psi area, if I remember correctly. High side pressures could reach 150+ depending on ambient temp.

I spoke wrong! Its the LOW side that I measured. But even so should the preasure be droping down to zero when I turn the a/c on?

Maybe you'd want to purchase a nice leak detector. Here's the one I have: PRODUCT: Robinair 16600 Refrigerant Leak Detector PRICE: 127.99 from RedHill supply. Make sure the schroder (spelling?) valves at the low and high ports are tight (a valve wrench comes with a new set you can buy for a few dollars. Also look underneath the grill at the condenser to verify no road debris has damaged it. That's what happened to mine.

The pressures are really meaningless unless you know exactly how much refrigerant is in the system and the only way you are going to know that is to draw in down and charge it with a weighed charge. Your not equipped to diagnose this properly. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

Please start another question of your own. We can't have two different things going in one question, it gets way too confusing. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.
