Why it matters
Refrigerant doesn't get 'used up' — if it's low there is a leak. Finding it prevents repeat visits and protects the compressor.
Frequently asked questions
Why is my A/C blowing warm air?
Common causes are a refrigerant leak, a failed compressor or clutch, or a faulty actuator. A leak test pinpoints it.
Is an A/C recharge enough?
Only if there's no leak. We test first so you don't pay to refill a system that drains again in weeks.
Do you fix heater problems?
Yes — heater cores, thermostats, coolant issues and blend-door faults.
