When you turn on the air conditioning in your vehicle, you expect cool air to come out of the vents.  You depend on it, especially in hot weather, but it can also be important in humid weather when you need it to help defrost your windows and windshield. The air conditioning system has a lot of parts to it.  It has fans and blowers to move the air through the vents into the cabin.  It has parts that take hot air and cool it off. An electrical problem can be as simple as a broken switch or a broken blower motor. The air may not be getting cool because a hose in the system is broken or the refrigerant has leaked out.  Two major components are the compressor and the condenser.  The compressor pressurizes the refrigerant, one step in the air conditioning process.  The condenser takes that hot refrigerant and cools it down. It also reduces the pressure. Because the climate control system in your vehicle is so complex, it’s best to leave the diagnosis to a ... read more

Air conditioning used to be a real luxury in a vehicle, but now it's standard in most.  Your vehicle's air conditioning system is built to last a pretty long time, but like anything mechanical, sometimes it fails.  It helps to know a little about how the A/C works. There's a compressor that pressurizes the refrigerant (you probably recognize the term Freon).  That makes it hotter, so it then goes through a condenser that cools it off.  Then another component takes out impurities and humidity before the Freon goes to a device that makes it lose pressure before it goes to the evaporator.  That's where it gets colder and takes the humidity out of the air. Then your vehicle's ventilation system blows air over the evaporator, cooling the cabin air that gives you such relief on a hot day. Of all these parts, one that does a lot of work is the compressor.  It has to compress that refrigerant and circulate it through the system.  It turns on and off several t ... read more

In warm weather, you want to be in a cool vehicle. When we're talking cool, we don't mean stylish or trendy, but cool as in not sweltering inside.  And if your vehicle's air conditioner stops working correctly, it seems to always break at the worst time—during a heat wave.  Automotive air conditioning problems fail for a number of reasons: Blower motor not working.  No air comes through the vents, even though the rest of the system could be working fine. Refrigerant leak. When the gas that cools the air off escapes from the air conditioning system, your air conditioner can no longer cool off the outside air Condenser and compressor. These are parts of your AC system that compress and expand a refrigerant gas to cool off the outside air. They are fairly complex. When you bring your vehicle into our service center, we'll run a series of diagnostic tests to figure out what isn't working correctly.  The air conditioning system has a lot of parts. There are elect ... read more

When you hear hissing sounds coming from your vehicle, you might start thinking the worst.   One type of hissing coming from around your air conditioner may be a normal sound, or it could be a sign of serious trouble. First - the normal sound.  When you turn off your vehicle, the refrigerant goes from its high-pressure side to the low-pressure side. Some of those noises are normal.  But when it hisses all the time, that's another story. One cause could be that the refrigerant is leaking.  Air conditioners are fairly complex systems that involve various pumps, hoses, valves and motors.  When your air conditioner is cooling, the refrigerant changes from a gas to a liquid and back.  That refrigerant is under pressure, and there are many places it can leak from.  A hissing sound can also be a failed valve in your air conditioner's compressor.  It is what controls the refrigerant's pressurization.  It's important to have this fixed fairly qu ... read more

On a hot day, you want your vehicle's air conditioning to work.  When the air blowing out of your vents isn't cold, it's easy to think, "I'll just take it by the shop and have them top off my refrigerant." But while some people think air conditioning is that simple, it's actually not. If your refrigerant is low, something has to have happened for it to be depleted.  Perhaps there's a leak in the system.  Or some hoses or clamps have failed.  If the system isn't evaluated by someone who knows air conditioning, it's possible that adding refrigerant will just be a band-aid solution. It's also possible that contaminants have gotten into the refrigerant, such as carbon dioxide, nitrogen, argon, or air.  Some of those gases do not condense like refrigerant does which can increase the pressure inside the system and strain the lines and other components. At that point, the best course of action may be to have the old refrigerant (with its contaminants) bled from the sy ... read more

Your vehicle's air conditioning is something you count on when the weather heats up.  But there's bound to be a day when you turn it on and one of these things happens: Only warm air blows out Cold air starts blowing out but then it turns warm on its own It's not blowing air at all It blows smelly air out Some people are tempted to try to make the diagnosis—and the repair—on their own.  They think it's just run out of refrigerant and they can pick up a can at a local auto parts store and re-charge it.   If only it was that easy. A vehicle's air conditioning system is complex and made up of many parts.  A compressor, evaporator, condenser, tubing, hoses, sensors, valves… the list goes on and on. Each of these components could be the reason for the problem.  It could be a leak that's letting the refrigerant escape, but simply re-charging the system hasn't fixed the problem. You have to find the source of the leak and fix it. Service faci ... read more

There's nothing quite like getting in your vehicle on a hot day, switching on the air conditioning and having warm air blow out of the vents.  You may have had no problem for months and then, one day, you are driving around in a sauna. You're hot stuff, but not in a good way! So what goes wrong when the AC isn't working? It could be a lot of things because the system has many different components.  One thing that's a common cause is the vehicle is low on refrigerant (it used to be called Freon).  If that's the case, it's not as simple as simply adding more.  Sure, it may fix it quickly for a short time, but it's more likely than not that the refrigerant will just leak out again. The original Freon used in air conditioners was destroying the Earth's ozone layer, so that's not used much any more.  But the one that's currently used also contributes to global warming, so it's important that as little of that escapes as possible.  So a technician will determine ... read more

No matter what vehicle you drive, when certain things break, you have to make a decision.  Should I get it fixed now, later or never?  Air conditioning is one of those things.  You can certainly live without air conditioning, but it sure is nice to have on a sweltering day. Let's say your air conditioning breaks in the fall and you live in a climate where it gets quite cold in the winter.  Should you get it fixed now, wait until spring since it won't get warm until then or maybe not get it fixed at all? That can be a tough decision.  There are several reasons air conditioning in vehicles break.  One is fairly simple: It could be an electrical problem, perhaps a relay or solenoid is not turning on the system.  It's also a fairly inexpensive repair and doesn't require hours of labor. Or, the problem is that the coolant has leaked out.  Your service facility can find the leak and replace the parts that are leaking.  With a refrigerant recharge ... read more

Most auto manufacturers recommend an interval for an air conditioning system inspection. The inspection uncovers leaks, worn hoses and assesses the condition of the other components.Environmental laws in some around Sacramento require leaks to be repaired before refrigerant can be added. Also some parts manufacturers require other components to be replaced along with certain failed parts in order to maintain the new part warranty. This is because a given failure may be the result of another worn or damaged part that will, if not replaced, prematurely damage the new component.Jack Dane Auto Service in Sacramento is fully equipped to restore your flow of cool air.Jack Dane Auto Service1200 I StSacramento, CA 958149164423287http://www.jackdaneauto.com  

Warm weather or cold, Sacramento drivers still need to think about their vehicle's air conditioning. Most Sacramento people don't service their air conditioning until after it fails. At Jack Dane Auto Service, we can advise you on your vehicle manufacturers preventive maintenance schedules for air conditioning service, just as we do for transmission service, oil changes and so on. Maintaining your air conditioning system means that you always have enough refrigerant to properly do the job. Small leaks in the vehicle's air conditioning system allow the refrigerant to escape and the system can't cool the air as well. We see that a lot at Jack Dane Auto Service in Sacramento.The refrigerant also contains oil that lubricates air conditioning components and keeps the seals resilient. Low refrigerant and lubricating oil means that the air conditioning parts will wear out prematurely, and all Sacramento vehicle owners know that air conditionin ... read more
