We understand all aspects of AC repair, from modern computerized components to environmental disposal concerns. Today's AC systems are fairly complex, and new improvements are always being initiated. That's why you need to turn to us, the qualified source for everything related to your air conditioning system. The following is a brief schematic of some of the basic components that comprise this system: compressor, condenser, receiver, orifice tube/expansion valve, evaporator.

When your vehicle's engine is off, the battery provides the required power to the rest of the system, as well as during start-up (cranking). It also supplements the power from the charging system during periods of high demand. Your vehicle's electrical system powers everything from the ignition and fuel systems to accessories such as your radio, headlights and wipers. The electrical system is, in turn, powered by the engine. Here are the three key components of the electrical system: Battery, Charging System, Starting System.

Wheel alignment is the position of the wheels relative to your car. When properly aligned, the wheels point in the right direction. Without proper alignment, the wheels resist your steering commands, as well as each other. Alignment also affects gas mileage and tire wear. If your tires are pointed in different directions, they fight against each other and can cause tread wear. Proper wheel alignment is integral to maintaining your vehicle.

Computerized alignment equipment is used to measure all alignment angles on your vehicle.. These include both adjustable and non-adjustable angles. (Non-adjustable angles require repair or replacement of the suspension component.) The most common adjustable angles are:

• Toe - This refers to the tilted direction of the wheels toward or away from one another when viewed from the top. Toe is the most critical tire wearing angle. Tires that "toe-in" point toward one another. Tires that "toe-out" point away from each other.
• Camber - This refers to the tilt of the wheels toward or away from one another when viewed from the front. Wheels that tilt in toward the vehicle have "negative camber." Wheels that tilt away from the vehicle have "positive camber."
• Caster - This refers to the angle of the steering axis in relation to an imaginary vertical line through the center of the wheel when viewed from the side. "Positive caster" is the term used when the vertical line is tilted back toward the rear. If it's tilted forward, we call it "negative caster." The proper caster angle stabilizes your car for better steering.
• Thrust Angle - This refers to the relationship of all four wheels to each other, as well as their relationship to an imaginary center line that runs from bumper to bumper. The term "thrust line" refers to the direction in which the rear wheels are pointed. Thrust angle is correctable on cars with adjustable rear suspensions. If your car has a non-adjustable suspension, thrust angle is compensated for by aligning the front wheels to the rear wheels.

Often confused with wheel alignment, a properly balanced wheel is a beautiful, perfectly tuned wheel-tire combination. This is accomplished by placing measured lead weights on the opposite side of the "heavy spot"-the noticeable tread wear on your unbalanced tire.

If your vehicle vibrating at certain speeds, say, between 50 and 70 mph, then chances are your vehicle may have a wheel that is out of balance. One section of your tire may be heavier than the others because it's endured more exposure to the friction and heat of the road. Come in for prompt, professional service-most people are very satisfied with the difference such a simple and inexpensive procedure makes. Look for one of these signs, and if you find either one, come see us:

• Scalloped, erratic wear pattern on tires.
• Vibration in steering wheel, seat, or floorboard at certain speeds.
