That faint clicking sound. The airflow that used to be powerful, now barely noticeable. Or maybe the air just isn’t as cold as it used to be. These might seem like minor annoyances, but they’re also the early signs of major car A/C problems. At Jerry’s Automotive in Lansing, MI, we see these issues every day, and we know what happens when they’re ignored. With summer just around the corner, now is the time to get ahead of the heat.
In this post, we’ll break down the top 5 auto A/C problems we see in our shop, plus how we fix them. You’ll also learn some lesser-known truths about refrigerants, smart maintenance tips, and why Lansing drivers trust us with their comfort, year after year.
The Top 5 Car A/C Problems Lansing Drivers Face (and How We Fix Them)
1. Your Car A/C Isn’t Blowing Cold Air
The issue: You crank up the A/C—and nothing but warm air hits your face. This is one of the most common problems, especially in late spring and early summer.
Possible causes:
- Low refrigerant (R134a or R1234yf)
- Faulty compressor
- Blocked expansion valve
- Leaking seals or hoses
Our fix: We run a complete A/C diagnostics service that includes checking refrigerant levels, identifying leaks, and testing system pressure. If needed, we’ll provide a car A/C recharge service using the appropriate refrigerant.
2. Weak or No Airflow from Your Vents
The issue: Your A/C might technically be working, but there’s barely any airflow—or none at all.
Possible causes:
- Clogged cabin air filter
- Blower motor failure
- Wiring or switch issues
- Mold buildup in ductwork
Our fix: We start by inspecting your cabin air filter and blower motor functionality. If there’s mold or buildup, we treat the ducts and flush the system. Our digital vehicle inspections (DVI) give you visuals of the issue so you can make informed decisions.
3. You Hear Strange Noises When the A/C Is Running
The issue: Clicking, grinding, or buzzing when the A/C is on often indicates something is failing internally.
Possible causes:
- Compressor issues
- Debris in blower fan
- Belt tensioner wear
- Internal refrigerant line damage
Our fix: We isolate the source of the noise and inspect the compressor clutch, fan assembly, and belts. Early repairs often save hundreds by preventing a total compressor failure.
4. There’s a Musty or Foul Smell from the Vents
The issue: If turning on your A/C fills the car with a stale odor, it’s likely mold or mildew in the system.
Possible causes:
- Moisture buildup in the evaporator
- Blocked A/C drain line
- Dirty cabin air filter
- Bacterial growth on the coils
Our fix: We clean the evaporator, sanitize the ducts, and replace your cabin filter. We also inspect for water drainage issues that could cause recurring moisture problems.
5. The A/C Turns On and Off Repeatedly (Short Cycling)
The issue: Your A/C might seem like it’s working, but it cycles on and off rapidly without cooling the car effectively.
Possible causes:
- Faulty pressure switch
- Overcharged or undercharged refrigerant
- Dirty condenser
- Thermostat or relay issues
Our fix: We use pressure gauges and thermal sensors to evaluate refrigerant balance and system pressure. If your system is using R1234yf, we recharge it safely to factory specs using EPA-approved equipment.

What Most Drivers Don’t Know About Refrigerant
Here’s something few repair shops talk about: Not all refrigerants are the same—and using the wrong type or overfilling your system can cause permanent damage.
If your vehicle was manufactured after 2015, it likely uses R1234yf, an eco-friendly refrigerant designed to meet strict emissions standards. But this new refrigerant requires specialized tools and technician training—most DIY kits don’t cut it, and not all shops in Lansing are equipped to handle it.
At Jerry’s Automotive:
- We are fully trained to work with R1234yf systems
- We invest in EPA-compliant recovery and recharge equipment
- We ensure refrigerant levels match manufacturer specifications
This means your A/C system stays efficient, and your warranty stays intact.
Preventative Maintenance for Lansing’s Weather
Michigan weather is unpredictable. One week it’s chilly; the next, it’s 90 degrees and humid. This constant shift places a strain on your car’s A/C system.
Here’s how to stay ahead of problems:
- Schedule annual A/C inspections
- Replace cabin air filters every 12,000–15,000 miles
- Recharge your A/C system as needed
- Use your A/C periodically during winter to keep seals lubricated
At Jerry’s Automotive, we help you plan ahead and prevent mid-summer breakdowns with convenient scheduling and fast service.
