Why Professional AC Service?
Auto AC Repair in Marietta GA – Stay Cool & Comfortable Year-Round
When your air conditioner blows warm air, makes rattling noises, or fogs up your windshield, ignoring it can lead to compressor failure and contaminated lines. Automotive climate systems rely on precise refrigerant levels, balanced high/low side pressures, and clean evaporator cores to deliver reliable cooling and defogging power.
At 875 Performance, we provide full-service automotive air conditioning and heater repairs for European, Japanese import, and domestic vehicles. Using certified R134a and next-gen R1234yf recovery machines, electronic sniffer probes, and UV dye testing, we solve leaks and restore freezing temperatures. Pair your AC service with our diagnostic inspection and engine cooling repair.
Ice-Cold Guarantee
Every AC recharge includes deep system vacuuming, exact factory oil injection, and multi-point vent temperature verification.

Systematic Diagnosis
Our 4-Step Auto AC Diagnostic & Repair Workflow
We locate the actual leak or mechanical fault before replacing parts or adding refrigerant.
01
Pressure & Vent Test
We attach manifold gauges to monitor high and low side operating pressures and record baseline duct temperature outputs.
02
Electronic Leak Scan
Using nitrogen pressure decay tests, UV tracer inspection, and electronic sniffers, we locate the exact point of refrigerant loss.
03
Component Repair & Vacuum
We replace leaking seals, lines, or failed compressors, followed by a vacuum hold to remove atmospheric air and moisture.
04
Precision Recharge & Test
The system is charged by weight with pure refrigerant and OEM oil, verified under high-load road testing for ice-cold vent output.
Marietta Driver Reviews
What Our Customers Say About Our AC Repairs
“My Mercedes C300 was blowing humid warm air right in the middle of July. Another shop told me I needed a $2,000 compressor. 875 Performance found it was just a failed pressure sensor and recharged it. Blowing 38°F now!”
“Late model Honda with the newer 1234yf refrigerant that most independent shops couldn’t service. They had the right machine, fixed a leaking Schrader valve, and finished same day. Excellent experience.”
“Replaced the squealing AC compressor on my Ford F-150 and flushed out the metal shavings from the lines so the new compressor wouldn’t fail. Professional mechanics who know what they’re doing.”

AC & Climate FAQs
Frequently Asked Questions About Auto AC Repair in Marietta GA
Why is my car AC blowing warm or slightly cool air?
Warm air is typically caused by low refrigerant from a hidden leak, a faulty compressor clutch, a blocked condenser, or a malfunctioning blend door actuator. We perform high-pressure tests to find the exact root cause.
Do you service both R134a and R1234yf refrigerant systems?
Yes. We have dedicated recovery and recharge stations for traditional R-134a systems as well as modern R-1234yf systems found in late-model domestic, Asian, and European vehicles.
Why does my car AC smell musty or foul?
Musty smells are caused by mildew, bacteria, or mold accumulating on a damp evaporator core or a clogged cabin air filter. We clean evaporator housings, treat ductwork, and replace dirty cabin filters.
How long does a car AC diagnostic and recharge take?
A standard AC performance test, electronic leak check, evacuation, and full recharge takes about 45 to 60 minutes. Major repairs like compressor or evaporator replacements are usually completed the same day.
Can you fix automotive heating and defrosting problems too?
Yes. We service complete automotive climate control systems, including heater cores, thermostats, blend doors, blower motor resistors, and heater control valves.
