Beat the Heat How to Keep Your Car Cool This Summer

When summer arrives in Northeast Ohio, it brings sunshine, road trips, and outdoor fun — but it also brings rising temperatures that can make driving uncomfortable, or even unsafe, if your vehicle’s air conditioning system isn’t in peak condition. Few things can ruin a summer drive faster than a car interior that feels like an oven. Whether you’re commuting across Greater Cleveland or heading out on a weekend adventure, maintaining your car’s A/C system is key to a comfortable, enjoyable ride.

At Rad Air Complete Car Care and Tire Centers, we know how important a working A/C system is to Northeast Ohio drivers, especially in July and August when the heat is at its peak. That’s why we offer expert air conditioning inspection and repair services at all 11 of our convenient locations across the region. Our goal is to help you beat the heat and keep your car cool all summer long.

In this article, we’ll explain how your car’s air conditioning system works, the common signs of wear or malfunction to watch for, and why regular A/C maintenance is essential. You’ll also learn how Rad Air can help you stay cool — no matter how high the temperatures climb.

How Your Car’s Air Conditioning System Works

Your vehicle’s air conditioning system is a complex network of components that work together to cool and dehumidify the air inside your cabin. Here’s a quick overview of the process:

• Compressor: The heart of the system, the compressor pressurizes refrigerant and circulates it through the system.
• Condenser: The refrigerant travels through the condenser, where it releases heat and turns into a high-pressure liquid.
• Expansion valve/orifice tube: The liquid refrigerant passes through an expansion device, dropping in pressure and temperature.
• Evaporator coil: The cold refrigerant absorbs heat from the air inside your car as it passes over the evaporator coil. This process cools the air, which is then blown into the cabin through your vents.
• Refrigerant: The refrigerant cycles through the system, continuously absorbing and releasing heat to maintain a cool cabin temperature.

Like any other system in your vehicle, your air conditioning system needs proper maintenance to perform its best. Over time, components can wear out, refrigerant levels can drop, and filters can become clogged — all of which can compromise cooling performance.

How Summer Heat Impacts Your A/C System

In Northeast Ohio, July and August temperatures often soar into the 80s and 90s, with high humidity levels that can make it feel even hotter inside your car. On sunny days, a parked car’s interior can reach well over 120°F in just 30 minutes. Your air conditioning system must work hard to quickly bring those temperatures down and keep them comfortable as you drive.

Extreme heat also puts added strain on your A/C system’s components:

• Refrigerant can degrade or leak over time, reducing cooling efficiency.
• Compressors work harder in high heat, increasing wear and the risk of failure.
• Rubber seals and hoses can deteriorate faster under constant heat and pressure.
• Clogged cabin air filters can restrict airflow and cause the system to struggle.

Without proper maintenance, even a well-functioning A/C system can lose efficiency in the summer months, making your drives less comfortable and potentially damaging critical components.

Signs Your A/C System Needs Attention

Being proactive about A/C maintenance is always smart — but it’s even more important if you notice any of these common warning signs:

• Weak airflow: If air coming from your vents is not as strong as it used to be, it could indicate a failing blower motor, clogged cabin filter, or restricted evaporator coil.
• Warm or inconsistent air: If your A/C is blowing warm or only intermittently cool air, your refrigerant level may be low, or there could be a problem with the compressor or expansion device.
• Strange smells: Musty or unpleasant odors when using the A/C often indicate mold or bacteria in the evaporator or cabin air filter.
• Noisy operation: Clicking, grinding, or squealing sounds when using the A/C may point to mechanical issues within the compressor or blower motor.
• Frequent cycling: If your A/C cycles on and off rapidly, it could be a sign of electrical problems, refrigerant issues, or sensor malfunctions.

If you experience any of these symptoms, it’s time to schedule a professional A/C inspection to prevent further damage and ensure your system can handle the demands of summer driving.

The Importance of Regular A/C Inspections

Many drivers don’t think about their air conditioning system until it stops working — but by then, repairs can be more expensive. Regular A/C inspections help catch small issues early, saving you money and preventing uncomfortable surprises during the hottest days of the year.

At Rad Air, our A/C inspection services include:

• Testing refrigerant pressure and levels
• Inspecting the compressor, condenser, and evaporator for leaks or damage
• Checking and replacing the cabin air filter as needed
• Inspecting belts and hoses connected to the A/C system
