5 Most Common Car A/C Repairs.
Is Your Car A/C Not Working Like It Should?
If your car’s air conditioning isn’t blowing cold air, smells funny, or only works intermittently, you’re not alone. Here in Conway, Arkansas, hot and humid summers make a working A/C system more than a luxury—it’s a must-have.
At CMS Auto Air Conditioning, we specialize in diagnosing and fixing the most common A/C issues quickly and professionally. Whether you’re searching for “car A/C repair near me” or simply want peace of mind before summer hits, this guide walks you through the top 5 most common car A/C repairs.
1. ❄️ Refrigerant Recharge (A/C Recharge)
The Problem:
Over time, refrigerant (the chemical that cools your air) escapes through small leaks or seals. Low refrigerant is the #1 reason your car blows warm or lukewarm air.
Symptoms:
- Air isn’t cold
- It takes a long time to cool the cabin
- Hissing sounds near the dash
The Solution:
A proper A/C recharge involves removing any remaining refrigerant, vacuuming the system to remove moisture, and refilling it to factory specifications.
Important Note:
DIY recharge kits can overcharge your system or mask leaks. Always let a certified mechanic handle this to avoid long-term damage.
👉 Local Tip: At CMS Auto Air Conditioning, we offer professional recharges with leak detection included—no guesswork, no gimmicks.

2. ⚙️ Compressor Replacement
The Problem:
The A/C compressor is the heart of your system—it compresses refrigerant and circulates it through the entire system. When it fails, your A/C stops working entirely.
Symptoms:
- No cold air at all
- Loud clicking or grinding when A/C is on
- Compressor clutch not engaging
The Solution:
A failed compressor must be replaced—there’s no shortcut here. In some cases, additional components like the accumulator or dryer need to be replaced at the same time to ensure the system works properly.
Why It Matters:
Driving with a bad compressor can send metal debris through your A/C system, contaminating other parts and driving up the repair cost. Early diagnosis can save hundreds.
Local Trust Factor: CMS Auto Air Conditioning in Conway uses OEM-grade parts and performs a full system flush before installing a new compressor—done right the first time.

3. 🧯 A/C Leak Detection & Repair
The Problem:
Leaks are the silent killer of any car A/C system. They’re often invisible, slow, and hard to find without specialized tools.
Common Leak Locations:
- Rubber hoses and O-rings
- Condenser (located at the front of the car)
- Schrader valves (the “ports” where refrigerant enters)
- Evaporator core (behind the dashboard)
Symptoms:
- A/C worked fine last month—now it doesn’t
- Recharging only helps for a short while
- Oily residue on A/C components
The Solution:
At CMS Auto, we use electronic leak detectors and UV dye to locate even the smallest leaks. Once located, we replace only the faulty components—not the whole system.
Pro Tip:
Never keep recharging your A/C if there’s a leak. You’re just throwing money into the air—and potentially harming the environment.

4. 🔌 Electrical or Sensor Issues
The Problem:
Your car’s A/C relies on sensors, relays, and wiring to function properly. Even if the mechanical parts are fine, one bad relay or a blown fuse can shut it all down.
Symptoms:
- A/C only works intermittently
- Blower runs, but no cold air
- Temperature settings don’t respond
The Solution:
Electrical issues require proper diagnostic testing. Our technicians at CMS Auto Air Conditioning use advanced scan tools to pinpoint faulty relays, switches, or wiring—not just guess and check.

We fix the problem without “throwing parts” at your car, saving you time and money.

5. 🌬️ Blower Motor or Fan Failure
The Problem:
If your car has cold refrigerant flowing through the system but no air is blowing out, your blower motor or cabin fan may have failed.
Symptoms:
- No airflow from vents
- Blower only works on one speed
- Burning smell from vents
The Solution:
We test the blower motor and resistor to confirm failure. If needed, we replace the motor with a high-quality unit, ensuring full airflow again.
The Danger:
A failed blower motor doesn’t just affect comfort—it can also impact defrosting in winter, reducing visibility and safety.
Why We Stand Out in Conway:
We install dependable parts, often same-day, and back our work with a satisfaction guarantee.
