Air Conditioning Service

It’s the first hot day of the summer. Uncomfortably shifting in your seat, you turn on that long-neglected AC knob, only to discover an unwelcome blast of warm air streaming out from the vents. A bad situation made worse: that’s when you turn to us—your air conditioning service and repair headquarters. Did you know that without regular maintenance an air conditioner loses about 5% of its original efficiency per year? This means that without proper maintenance, your air conditioning unit may be performing as poorly as other models that are years older! But there is good news: you can still recover most of that lost efficiency. Schedule an appointment with one of our factory-trained professionals—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:

• The compressor is a belt-driven device that derives its name from compressing refrigerant gas and transferring it into the condenser. While basically acting as a simple pump, the compressor is the core of your vehicle’s air conditioning system.

Condenser:

• The condenser’s primary function is to cool the refrigerant. It is a heat dissipating apparatus that radiates heat released by compressed gases and condenses them into high pressure liquids. The location of your condenser depends on how new your car is, but typically it’s found at the front of the vehicle, directly in front of the engine cooling radiator.

Receiver (drier):

• The receiver is a metal container that serves as a storage receptacle for the refrigerant. It’s also referred to as a drier because it absorbs moisture from the refrigerant and filters out particles of debris and harmful acids that would otherwise harm your AC system. Commonly located on the liquid line of the AC system, you should change your drier every 3-4 years to insure quality filtration and prevent any damage caused by these detrimental chemicals.

Orifice tube/expansion valve:

• The orifice tube (also known as the expansion valve) is a controlling mechanism that regulates the flow of refrigerant throughout the system. In addition to this, it also converts high pressure liquid refrigerant (from the condenser) into a low pressure liquid, so that it can enter the evaporator. Generally located at the evaporator inlet, the orifice tube could also be found between the condenser and the evaporator, or in the outlet of the condenser.

Evaporator

• The evaporator is designed to remove heat from the inside of your vehicle; therefore it’s a heat exchanger that’s vital to your vehicle’s AC system (not to mention your comfort). The evaporator allows the refrigerant to absorb heat, causing it to boil and change into a vapor. When this occurs, the vapor is removed from the evaporator by the compressor, cooling your car and reducing humidity. Because the evaporator houses the most refrigerant in this heat transfer process, it is the most susceptible to corrosion by harmful acids. Usually this damages the evaporator beyond repair, which is why it’s imperative you see us to prevent this from happening.

Your car’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

• • When your car’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.

Charging System

• • This is the heart of the electrical system. It consists of three main components: the belt-driven alternator, various electrical circuits, and a voltage regulator. The alternator supplies power to the electrical system and recharges the battery after your car has started. Just like it sounds, the voltage regulator controls the voltage, keeping it within the operating range of the electrical system.

Starting System

• This system consumes more electrical power than any other in your car. The starting system consists of three components which work in tandem: the ignition switch, the starter relay or solenoid, and the starter motor. The ignition switch controls the starter solenoid, which activates the starter motor. The starter motor then turns the engine until your car starts.

Exposure to heat, vibration and contamination makes belts and hoses wear out faster than any other components in your car. That’s why regular inspections are so important. Here are the belt and hose types in your car, along with their applications.

Accessory Drive Belts

While some accessories in your car are electrically powered by the charging system, others use the engine itself as their power source. The power for these accessories is delivered by a system of pulleys and belts. Examples of these accessories are:

• Alternator
• Water Pump for engine cooling
• Power Steering Pump
• Air Conditioning Compressor
• Radiator Cooling Fan
• Many late model cars use a single serpentine belt in place of individual belts to drive these accessories.

Hoses

The hoses that convey your car’s fluids are made of two rubber layers with a layer of fabric in between. Typical hoses include:

• Radiator and Heater Hoses – These hoses convey coolant to the engine and heater core.
• Fuel Hose – As the name implies, this hose transports gasoline from the tank to the engine.
• Power Steering Hose – It connects the power steering pump to the steering gear.

Computerized Engine Analysis

Your modern vehicle’s engine is a highly sophisticated piece of equipment. The days of your father’s gas-guzzler are long gone—instead, Federal Exhaust Emission and Fuel Economy regulations demand that today’s vehicles be equipped with electronic engine control systems, to curb carbon emissions and increase fuel efficiency. With technically-advanced control systems taking the place of simple engine components, common maintenance services such as tune-ups are also a thing of the past. Regular services (such as spark plug and filter replacements) are still required, as well as a computerized analysis of your vehicle’s control computer. Our factory-trained technicians are here to provide these basic services.

Here’s how your modern vehicle’s control computer operates:

A network of sensors and switches convert and monitor engine operating conditions into electrical signals. The computer receives this information, and, based on information and instructions coded within this savvy computer program, commands are sent to three different systems: ignition, fuel, and emission control. Whenever a problem arises (as seen by that nagging “check engine” light), our service pros check whatever command is prompted, in addition to the status of your engine control computer and sensors. That way you’ll know if your vehicle’s performance is caused by a real problem, or just a sensor/computer issue.

Here’s a brief overview of your vehicle’s sensory components:

• Mass airflow sensor
• Throttle position sensor
• Manifold absolute pressure sensor
• Coolant temperature sensor
• Exhaust oxygen sensor
• Crankshaft position sensor
• Camshaft position sensor

CV & Drive Axle

The axle on your vehicle is the structural component that connects two wheels together on opposite sites. It’s a load-bearing assembly that acts like a central shaft, maintaining the position of the wheels relative to each other and to the vehicle body. The construction of your axle is designed according to what your vehicle is built for; trucks and off-road vehicles are equipped with axles that keep the wheel positions steady under heavy stress (ideal for supporting heavy loads), while conventional axles are constructed for the needs of the general consumer. But no matter what you drive, remember that your vehicle’s axle must bear the weight of your vehicle (plus any cargo) and the acceleration forces between you and the ground. So when it comes to axle inspection, we are your source for professional, knowledgeable service—essential for the equipment that carries you and your family to wherever you need to go.

Here is a brief description of the most common axle design:

Drive/CV Axle:

Simply put, a drive axle is one that is driven by the engine. Typically found in modern front wheel drive vehicles, a drive axle is split between two half axles, with differential and universal joints between them. Each half axle is connected to the wheel by a third joint—the constant velocity (CV) joint—that allows the wheels to move freely. This joint allows the shaft to rotate, transmitting power at a constant speed without a significant increase in friction and heat. CV joints are usually dependable, but, as is the case for all of your vehicle’s moving equipment, they do require regular inspection. An easy way for you to tell if you need to see us for axle repair is to go out to a large space (such as a parking lot), and slowly drive in tight circles. If you hear a clicking or cracking noise, you have a worn joint, and it must be repaired immediately.

We will have you back on the road, “click-free” in no time!

Exhaust

Your exhaust system is more than a muffler. It is a series of pipes that run under your car, connected to your muffler and catalytic converter. The main function of your exhaust system is to control noise and to funnel exhaust fumes away from passengers.

In some ways, a car’s exhaust system works like a chimney on your house, directing the byproducts from burning fuel away from the people inside. A car’s exhaust system routes waste gases from the engine to the rear of the car, where they are discharged into the atmosphere. Exhaust gases contain dangerous substances such as carbon monoxide, which can be hazardous if allowed to flow into the passenger housing of the car.

The exhaust system also converts pollutants into less harmful byproducts, reduces the noise of the engine, and directs exhaust gases so they can be used to heat air and fuel before they go into the engine’s cylinders to be burned. Finally, the exhaust system provides just the right amount of backpressure into the engine to improve its fuel-burning efficiency and increase performance. Key components of your exhaust system include:

Exhaust Pipes:

Designed specifically for each car model to properly route exhaust to the back of the car.

Exhaust Manifold:

Acts like a funnel, collecting exhaust gases from all cylinders and releasing it through a single opening. Some engines have two.

Catalytic Converter:

Designed to reduce the amount of harmful emissions products by transforming pollutants into water vapor and less harmful gases.

Muffler:

Metal container with holes, baffles, and chambers that muffles exhaust noise.

Resonator:

Works with the muffler to reduce noise.

Tail Pipe:

Found at the back of the car, the tail pipe is designed to carry exhaust gases away from the vehicle

All components of the exhaust system are connected with a series of clamps, hangers, flanges, and gaskets.

Tires & Wheels: Tire Rotation

Description: Tire rotation refers to the regular practice of switching the position of each tire on the car.

Purpose: Tire rotation helps to equalize tread wear and is critical to gain the maximum life from your tire investment.

Maintenance Tips/Suggestions: Refer to your owner’s manual for the recommended rotation interval and pattern; generally a rotation interval of 6,000 miles is recommended. The rotation pattern varies with different makes and models, which shows the tire locations during rotation. Some vehicles have different size tires on the front and back or directional tires. This limits the locations that a tire may take on the vehicle. When in doubt, check the owner’s manual or consult a professional technician for guidance. Tire rotation time also offers a good opportunity to have the tires and wheels balanced. It’s another step you can take to maximize your tire investment.

Transmission Maintenance

For those of you who aren’t mechanically-savvy, you probably still understand that transmission problems are among the most expensive repairs required for your vehicle. That’s because your transmission is a complex system of gears that transmit mechanical power to your engine, ultimately determining the rate of speed you travel. Transmissions convert this power from the engine so that it can supply high torque at low speeds, in addition to selecting which gears are appropriate based on the driving conditions. This is especially true with automatic transmissions—by far the most popular transmissions found in the US. Rather than using a clutch to engage the transmission, automatic transmissions use a torque converter (between the engine and transmission) to control the number of gears when driving. Supplying the power to regulate gear action is a demanding task, which is why it’s important for you to contact us, your transmission service specialists. Here are some of the essential maintenance tasks we complete:

• Drain transmission and torque converter
• Refill Automatic Transmission Fluids (ATF) with new fluid

Transmission problems typically arise when regular service is neglected. When fluids aren’t properly changed, heat caused from mileage friction results in rough shifting, accelerated wear, and even complete failure. That’s why it’s essential that you turn to us to make sure that your transmission is lubricated and cooled by the finest quality transmission fluids, installed by our service professionals.
