AC Repair & Diagnostic
in Sarasota, FL
Automotive Air Conditioning Diagnostics at Sherman’s Auto Repair
In Florida, a properly functioning air conditioning system isn’t a comfort feature—it’s a necessity. When your vehicle’s AC begins blowing warm air, cycling inconsistently, or failing altogether, the issue is rarely limited to a single component. Automotive air conditioning systems rely on precise pressure balance, correct refrigerant levels, and properly operating electrical controls.
At Sherman’s Auto Repair, AC issues are diagnosed by ASE-certified technicians using system-level testing to identify the true cause of failure. We do not recharge systems blindly or replace parts without confirmation. Our focus is restoring correct operation—not masking symptoms.
Signs Your AC System Needs Repair
It’s important to be vigilant for certain indicators that your vehicle’s AC system may require repairs. Here are the signs to watch for:
- Weak Airflow: When the air from your AC feels warm or faint, it could point to problems with essential components like the filter, blower motor, or ducts.
- Strange Odors: If you’re noticing odd smells, such as a musty or moldy scent from the vents, it’s likely there’s mold or mildew in the system that needs cleaning.
- Noisy Operation: Hearing squeals or grinding sounds when your AC is on usually means there’s a problem with the compressor or other parts.
- Leaks: Any visible leaks or puddles under your car can be regular condensation, or can also be signs of a leak in the coolant system which runs through the A/C system to give you heat.
- Inconsistent Cooling: If your car can’t keep a steady cool temperature, it’s a sign that your AC system isn’t working right.
If you’re experiencing any of these AC problems, head straight to Sherman’s Auto Repair. We’ll conduct a thorough assessment and provide top-notch repair services to make sure your AC is in perfect working order, keeping you comfortable and safe during your drives.
Why AC Problems Are Frequently Misdiagnosed
Many AC services focus only on refrigerant level. While low refrigerant is common, it is usually the result of another problem—not the cause.
Without proper diagnostics:
- Leaks go undetected
- Compressors are damaged by improper pressure
- Electrical faults are missed
- Cooling performance declines again shortly after service
True AC repair requires understanding how the compressor, condenser, expansion device, evaporator, and control systems interact.
Our AC Diagnostic Process
Effective AC repair starts with verification.
Our diagnostic process includes:
System Pressure Testing
We evaluate high- and low-side pressures to determine whether the system is operating within specification.
Leak Detection
Refrigerant leaks are identified using proper detection methods before any recharge is performed.
Electrical & Control Testing
We inspect sensors, switches, relays, and control modules that regulate AC operation.
Component Performance Evaluation
Compressors, fans, condensers, and expansion components are tested for proper function.
Clear Repair Recommendations
Once the fault is confirmed, we explain what has failed, what remains serviceable, and what is required to restore reliable cooling.
AC Recharge vs. AC Repair
An AC recharge alone does not fix underlying problems.
Recharge addresses refrigerant loss—but not why it occurred
Repair corrects leaks, component failure, or control issues
Recharging a leaking or malfunctioning system often leads to repeat failure and higher repair costs.

Frequently Asked Questions (FAQs)
What should I do if my AC is running but not cooling?
First, check if the air filters are clean, as dirty filters can block airflow. Also, examine the outdoor unit for blockages. If these aren’t the issues, it could be a refrigerant leak, which requires professional attention.
Why is there a strange smell coming from my AC?•
Odd smells can signal mold or mildew growth within the system, which needs cleaning. It’s important to address this quickly as it can affect air quality and your health.
What does it mean if my AC is making loud noises?
Squealing or grinding noises can indicate a problem with internal components like the compressor. It’s best to have a technician inspect the system to prevent further damage.
How can I tell if my AC system is leaking?
Puddles or leaks near the unit can be signs of refrigerant leaks. These should be repaired promptly to ensure efficient operation and prevent potential environmental harm.
Why is the airflow from my AC weak?
A dirty cabin filter, issues with the blower motor, or clogged ductwork can cause weak airflow. A technician can diagnose and fix the problem to restore proper air circulation.
