We have the latest equipment so we can quickly diagnosis all air conditioning problems. We pinpoint the smallest leaks, replace bad electrical sensors, and perform complete car a/c system replacements.

How your car’s Air Conditioning Systems Work

The first component of a car air conditioning system is the gas. The gas used in air conditioners is called Freon. The Freon is put into a sealed system. The Freon is then pressurized using a compressor. As it is pressurized, it gets hot by absorbing the heat around it. The hot Freon is then circulated to the condenser.

The condenser is a device mounted in front of the radiator and behind the grille; it looks a lot like a radiator. The condenser is used to change the high-pressure Freon vapor to a liquid. Air flowing through the condenser removes heat from the Freon changing it to a liquid state or now a refrigerant.

The refrigerant then moves to a receiver drier or an accumulator depending on the type system you have. Moisture is removed from the refrigerant because moisture can freeze causing a blockage. The drier or accumulator are also storage tanks for the liquid refrigerant keeping it from moving out to the compressor and causing damage to it. The compressor is designed to compress gas not liquid. The liquid refrigerants pressure is lowered by an expansion valve for receiver drier systems or an orifice tube for accumulator systems and turns it into a refrigerant gas in the evaporator.

As the cold low pressure refrigerant is released into the evaporator, it vaporizes and absorbs heat from the air in the passenger compartment. As the heat is absorbed, cool air will be available for the occupants. The same blower for the heating system blows air through the cold evaporator and distributes it through the air conditioning ducts in the vehicle.

Air Conditioning Service

When to Service:
Annually before the weather warms
When you notice performance beginning to deteriorate

The Service Includes:
An in depth inspection of lines and hoses
Test and record the systems high and low pressure readings
Check and record the temperature of the air from the air conditioning vents at maximum cool setting
Refrigerant cleansing; because refrigerants are harmful to the environment, we take special care according to our Environmentally Sustainable Actions Certification Program and use the proper recovery machines to ensure that none of the material escapes during service.

Benefits:
Comfort!
By keeping your air conditioner properly maintained you will reduce repair costs for compressor and all other components.

Special Considerations:
The Environmental Protection Agency determined that the refrigerant Freon also known as R-12 or CFC-12 was damaging the ozone layer and stopped production of the material. Now R-12 Freon is hard to find and very expensive. Although most vehicles produced before 1995 use R-12 in their air conditioning systems our Technicians can retrofit your vehicle to the new approved R134a. R134a is a more environmentally friendly refrigerant. This retrofit is more cost effective than attempting to repair the older systems.

R134a Retrofit Service

The Service Includes:
Case by case evaluation on what will be needed
R-12 Freon is recovered along with the R-12 oil and properly disposed according to EPA regulations
The system is flushed
Install the R134a retrofit kit (a small number of vehicles may require different seals and hoses)
Evacuate and recharge the system with R134a refrigerant and compatible oil
Install mandatory retrofit labeling

Benefit:
Considerable reduced cost to service you’re A/C system in the future
Environment protection

Special Issue:
Retrofitting for cost and environmental savings can be done even if your older air conditioning system is functioning. However, a retrofit will not fix a broken air conditioning system.

What’s an alignment and why do I need one?
Alignment by definition is making something even. Periodically, and sometimes after an accident (even just hitting a curb), it’s ideal to have your car’s alignment adjusted. This extends the life of the tires and makes the vehicle easier to drive straight. We look at camber, toe and castor settings in order to identify and resolve your alignment issues.

We often hear:
“My car is pulling to one side while I drive.”
“My car is bumpy when I drive.”
“It’s difficult to steer my car.”
“It seems like one corner of my car is sitting lower than other parts.”

If you experience this while you are driving, we recommend having your alignment checked because none of the scenarios are safe for you and your family. Guess what?

We offer free alignment checks! So it doesn’t cost you anything to find out if this is what’s causing your steering issue.
What’s the difference between an alignment and suspension work?

Alignments have to do with the positioning of the wheels. Think tires not perfectly parallel (The exact factory settings vary per make and model). The suspension is what breaks the impact of bumps on the road. This system of parts also control steering on the vehicle. Still not sure if you need an alignment or suspension work? Why not both? WE OFFER FREE ALIGNMENTS WITH SUSPENSION WORK
