Air Conditioning - Auto Repair & Service

A. Nobody likes getting into a sweltering car, but it's such a relief to turn on your AC and feel that cool air kick in. Until the day it doesn't kick in. Or maybe your car's air conditioner activates but doesn't cool your cabin the way it used to.

To prevent car AC breakdowns, follow your vehicle manufacturer's suggested maintenance schedule -- and have your AC checked at the first sign of trouble.

If you're already having AC problems, request a Car AC Check appointment today.

How do I know if my AC needs to be recharged?

Why is my car blowing cold air when the heat is on?

A. Between the compressor, the AC clutch, and (most commonly) the refrigerant level, there are several reasons why a car air conditioner can stop blowing cold air:

• Refrigerant loss: Low refrigerant (coolant) is the most common cause of AC problems, and the solution is a Car AC Recharge -- plus repairs to any leaking AC components that may be causing your vehicle to lose refrigerant faster than expected.
• Blocked air flow: Anywhere between the compressor, the condenser, and the air vents into your cabin, any blockage to air flow will shut down your AC system.
• Broken or worn AC parts: Depending on the vehicle, your AC system may include a compressor, AC clutch, condenser, thermal expansion drive, receiver, dryer, orifice tube, accumulator, evaporator, and blower. Any of these parts, and the lines and connections between them, may need service.

A. There is no industry-standard interval to check vehicle climate control systems. Best advice: follow the maintenance schedule in your vehicle manual.

sYour local Midas technician will discuss the results of your AC Check with you before making any repairs. And remember, every Midas Touch Courtesy Check1 includes a visual inspection of your vehicle's AC system. It's one more reason to make Midas a regular part of your vehicle maintenance routine.

A. You know your car AC system needs service when it cools less effectively or refuses to kick in at all -- but here are some signs that your compressor is the culprit:

• Unusual compressor noise: In the compressor, worn-out bearings or other interior components can cause (noisy) friction.
• Visible damage, debris, or dirt on the compressor.
• The compressor clutch won't engage: Listen the next time you turn your AC on. You'll hear a switch moving before your compressor kicks in. That's the clutch switch. It can break (or get stuck in the off position).

A. While the air compressor is just one part of your car AC system that can break down, it's a part that many drivers understand from dealing with AC problems at home. Here are some common causes of AC compressor failure:

• Refrigerant is too low to maintain air pressure
• Low lubricant
• Blocked suction lines
• Dirty coils
• Electrical problems
