Question for A/C Experts. Service the A/C on My 2006 or Leave Well Enough Alone?

The Air conditioning on my Cobalt works but it is 10 years old and has never been serviced. From what I have read about a/c systems in the past, it is not uncommon for a vehicle's a/c system to loose a couple ounces of refrigerant every year due to leakage past the seals, etc. I'm guessing that running the a/c without an adequate amount of refrigerant is not good for the system.

Should I have an a/c expert evacuate and then charge the a/c system?

Back in the "old days" my dad would check the sight glass in our GM vehicle's a/c system and if there were bubbles he would add refrigerant to the system with a/c charging system (gauges and hoses, he was an HVAC person). I'm guessing that the modern GMs no longer have this sight glass.

2006 LS. Automatic. 4 Door. 31k miles.

If it's still blowing cold air and you are having no issues I would leave it alone. But if you feel that the pump is working all the time or the cooling fans come on more than usual you may want to get it serviced. This is one area I found where it is better to bring to a Pro.

Right- Depends on how cold the air is at the vent. Measure it with a thermometer. Should be about 30 -35 deg F below ambient temp. Do not open up/evacuate if you dont need to.
