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.
