Frequently Asked Questions
How often does car AC need to be recharged?
A properly sealed system should never need recharging — refrigerant doesn't 'wear out.' If your AC isn't cold, there's likely a leak. A typical system loses about 5-10% per year naturally, so a slight decrease over several years is normal.
Can I recharge my car AC myself?
Yes, for R-134a systems — DIY kits ($20-$50) with a gauge are available at auto parts stores. For R-1234yf systems (most 2015+ cars), professional service is recommended due to the expensive refrigerant and environmental regulations.
