When Michigan summer temperatures climb, there’s nothing more important than a properly working car air conditioning system. Whether you’re driving through Chesterfield Township, Royal Oak, or St. Clair Shores, a cool and comfortable ride can make all the difference. But just like any system in your vehicle, your auto AC needs regular care to stay in peak condition. Here’s how to make sure your car’s AC system is ready to beat the heat.
Why Auto AC Maintenance Matters
Your car’s air conditioning system is made up of several parts: the compressor, condenser, evaporator, expansion valve, and refrigerant. If any of these parts become damaged or inefficient, your AC won’t blow cold air — or worse, it could stop working altogether. Regular maintenance not only keeps the system running well, but also helps prevent more expensive repairs down the road.
Common Signs Your Car AC Needs Service
Many drivers don’t realize there’s a problem with their air conditioning until it’s too late. Watch for these warning signs:
- Warm air blowing from the vents
- Strange smells coming from the AC system
- Weak airflow even on high settings
- Unusual noises when the AC is running
If you notice any of these issues, it’s time to schedule an AC inspection with a certified auto technician.
How to Maintain Your Car’s AC System
Here are some simple steps to help keep your AC system working efficiently during the summer months:
1. Run Your AC Regularly
Even in cooler weather, running the AC for a few minutes each week helps keep the system lubricated and prevents seals from drying out.
2. Replace the Cabin Air Filter
Your cabin air filter plays a big role in airflow and air quality. A dirty filter can strain your system and reduce cooling. It’s recommended to replace it every 12,000 to 15,000 miles or once a year.
3. Get a System Inspection Before Summer
Before peak heat arrives, schedule a full AC system inspection. A trained mechanic will check refrigerant levels, compressor function, and all system components to ensure everything is in good shape.
4. Check Refrigerant Levels
Low refrigerant is one of the most common AC problems. If the system is low, your AC may blow warm air. A professional recharge service can restore performance.
5. Keep the Condenser Clean
The condenser sits at the front of your vehicle and helps cool down the refrigerant. Dirt, debris, or bugs can block airflow and cause the system to overheat. Periodically inspect the front grille and gently clean away buildup.
Frequently Asked Questions
How often should my car’s AC be serviced?
It’s a good idea to have your AC inspected at least once a year, ideally in the spring before summer driving begins. Regular inspections help catch issues early and prevent breakdowns.
Why does my car AC smell bad?
Foul odors may come from mold or mildew growing inside the evaporator or cabin air filter. Replacing the filter and cleaning the AC system can usually fix this.
Can I recharge my AC myself?
While DIY kits exist, it’s best to let a certified mechanic recharge your AC. Improper handling of refrigerants can damage the system or cause injury.
