Frequently Asked About AC Repair

How often should my car's AC be recharged?

A properly sealed system never needs a recharge. If you’re losing cool air, you have a leak. We don’t just top it off — we find and fix the leak so you stay cool for years.

We strongly advise against it. DIY kits often overfill the system (causing compressor failure) and don’t fix leaks. Plus, modern R1234yf systems require specialized machines. Let us do it right the first time.

Simple recharges or filter swaps: 1–2 hours. Compressor or evaporator replacement: half to full day. We’ll give you a clear time estimate after diagnosis.

Yes — we have state-of-the-art recovery/recharge machines that handle both refrigerants. Whether you drive a 2005 Honda or a 2023 Subaru, we’ve got you covered.

Our AC performance check is $250-$599 and differ from manufacturer or model (call for current special). If you book a repair with us, we often apply the diagnosis fee toward the repair. Call (209) 672-2347 for upfront pricing.
