To schedule an evaluation, call (337) 520-8460 and let our Broussard team help restore reliable cooling.

Auto AC Diagnostics, Recharge, and Leak Detection

Effective AC repair always begins with testing. Our diagnostic process is designed to identify the true cause of cooling problems so you don’t pay for unnecessary parts or repeat services.

What Our AC Diagnostic Includes

• Vent temperature and airflow performance testing

• High- and low-side pressure readings

• Visual inspection of hoses, fittings, compressor, and condenser

• Leak detection using dye or electronic methods when needed

• Verification of condenser fan operation and airflow

• Cabin air filter and HVAC airflow inspection

Refrigerant does not “wear out” under normal conditions. If your system is low, there is usually a leak that needs to be addressed. An AC recharge can restore cooling, but without repairing a leak, the problem often returns—especially during peak summer heat in Broussard. Once testing is complete, we review the results with you and explain repair options clearly before any work begins.

Why Your Car AC Blows Warm Air at Idle

If your AC cools well while driving but blows warm air at stoplights, the system may be struggling to remove heat when airflow is reduced.

Common Causes of Warm Air at Idle

• Low refrigerant charge from a small leak

• Condenser fan not operating correctly

• Blocked or restricted airflow across the condenser

• Compressor clutch or control issues

• Elevated under-hood temperatures

Our technicians test AC performance under real-world conditions, including idling in traffic, to pinpoint the issue accurately. Once the cause is identified, we recommend the most direct repair to restore consistent cooling and protect system components.

Signs Your AC Compressor May Be Failing

The AC compressor is the heart of the system. When it begins to fail, cooling often becomes inconsistent and noisy, and additional components may be put at risk.

Warning Signs of Compressor Trouble

• Grinding, squealing, or rattling noises

• Intermittent or uneven cooling

• Compressor clutch not engaging properly

• Abnormal pressure readings

• Burning smells or visible heat damage

• Metal debris indicating internal wear

Early diagnosis can prevent widespread contamination that turns a simple repair into a major one. When replacement is needed, we also advise on supporting components and proper system flushing to ensure long-term reliability through Louisiana summers.

Musty Odors, Interior Water Leaks, and Cabin Air Filters

A musty smell from AC vents is often caused by moisture and microbial buildup inside the HVAC system—an issue that develops quickly in humid climates.

Related AC Comfort Issues

• Musty odors: Often tied to dirty cabin air filters or moisture on the evaporator

• Water leaking inside the cabin: Commonly caused by a clogged or disconnected drain tube

• Reduced airflow: Frequently linked to an overdue cabin air filter replacement

Addressing these issues promptly helps prevent interior damage, persistent odors, and fogging windows. Regular cabin air filter service and drain inspections keep your AC system clean and efficient.

DIY AC Recharge Kits vs. Professional AC Service

DIY recharge kits may seem convenient, but they carry risks. Overcharging the system, using sealers, or adding the wrong refrigerant can increase pressure, damage the compressor, and complicate future repairs—especially on systems using R-1234yf.

Professional AC service ensures:

• Correct refrigerant type and charge by weight

• Safe recovery and handling of refrigerant

• Accurate leak detection and system testing

• Protection of critical components

For dependable results, professional diagnostics and service are the safest approach.

Why Hire Christian Brothers Automotive Broussard

• Accurate, evidence-based AC diagnostics

• Service for both R-134a and R-1234yf systems

• Clear explanations and upfront pricing

• Experienced technicians who understand local driving conditions

• Focus on long-term reliability, not temporary fixes

Our goal is cold, consistent airflow you can rely on—without repeat visits.

AC Services FAQs

How long does an AC recharge take?
In many cases, about an hour. Additional repairs or leak fixes may extend service time.

Does a recharge fix every AC problem?
No. If refrigerant is low due to a leak or component failure, the underlying issue must be repaired.

How often should cabin air filters be replaced?
Typically once a year or every 12,000–15,000 miles, or more often in dusty or high-pollen areas.

Can I drive with a failing AC compressor?
It’s possible, but continued use can lead to more expensive damage if debris spreads through the system.

If your vehicle’s AC isn’t keeping up with Broussard’s heat, don’t wait for the problem to get worse. Contact Christian Brothers Automotive Broussard at (337) 520-8460 to schedule an AC diagnostic and get back to cool, confident driving in Broussard, LA.
