To Fix or Not To Fix: That Is the Question.

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

A Hot Mess (AC System-Compresser)

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

I'm Cool With That (AC Exchange)

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

Full of Hot Air (Air Conditioning)

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

Automotive Tips from John's Automotive Care: Air Conditioning ? Common Problem

Your auto air conditioning system cools and conditions the air in your passenger compartment when you are driving around San Diego. It also removes moisture from the air to keep your windows from fogging up.A common A/C problem for San Diego drivers that visit John's Automotive Care is contaminated refrigerant (the gas that cools the air). The inside of the A/C hoses deteriorates over time and tiny fragments of rubber clog passages. This makes the system less efficient and overworks various components.Leaks can develop at seals and gaskets and may reduce the amount of refrigerant, causing the system to work too hard to compensate. Dirty components can have the same consequences.Ask your John's Automotive Care service advisor for an air conditioning system inspection to make sure everything is up to spec.John's Automotive Care6267 Riverdale StSan Diego, CA 92120619-280-9315http://www.johnsautomotivecare.com   ... read more

San Diego Air Conditioning Service

Working up a sweat is a great thing to do in a gym around San Diego, but not in your vehicle. When San Diego residents' vehicle AC Systems have a problem, they'll often feel it right away. The question is, how long do you put up with it? You know, the old comfort versus cost dilemma. But a more comfortable drive around CA has a lot of benefits, and keeping the AC System well maintained can help prevent repairs.A common cause of AC failure is water and air in the system. The system does not work as well with air in it. And water can cause rust that leads to damage of the A/C components. Also refrigerant, the stuff that makes the air cold, can leak out, reducing the efficiency of the system and making it work harder to try to cool the air. That is why periodically evacuating the air conditioning system and recharging it keeps the proper amount of clean refrigerant in the system for San Diego residents, so it cools better and lasts longer.San Diego drivers should also ... read more

Automotive Tips from John's Automotive Care: Making Your A/C System Last Longer

San Diego drivers know that if their air conditioning system isn’t making cool air like it used to, there is a problem. It may be as simple as adding more of the right kind of refrigerant.Your A/C requires special compressor oil, which circulates through the system along with the refrigerant, to lubricate and protect expensive components and keep seals and gaskets from drying out. If refrigerant has leaked out – so has the compressor oil. This oil needs to be replenished whenever refrigerant is added.An air conditioning inspection at John's Automotive Care will uncover any potential problems and identify any necessary repairs needed to get San Diego drivers on the road to cool air once again.Give us a call.John's Automotive Care6267 Riverdale StSan Diego, CA 92120619-280-9315http://www.johnsautomotivecare.com

Automotive Tips from John's Automotive Care: Air Conditioning Inspection

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 San Diego 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.John's Automotive Care in San Diego is fully equipped to restore your flow of cool air.John's Automotive Care6267 Riverdale StSan Diego, CA 92120619-280-9315http://www.johnsautomotivecare.com

Air Conditioning Maintenance at John's Automotive Care in San Diego

Warm weather or cold, San Diego drivers still need to think about their vehicle's air conditioning. Most San Diego people don't service their air conditioning until after it fails. At John's Automotive Care, 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 John's Automotive Care in San Diego.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 San Diego vehicle owners know that air conditioning re ... read more

Keep Your Cool in San Diego: Air Conditioning Services

  Most San Diego drivers don't even think about their air conditioner. Now here's a tip for San Diego vehicle owners: Run your air conditioner every so often during CA winters. This circulates the lubricant to help keep the seals from drying out. The air conditioner actually removes some of the moisture in the air. So if you have trouble with fogging on your vehicle windshield during CA winters or during a rain storm, running the A/C on the defrost setting should help. Now on some San Diego cars you can't run the A/C at the same time as the defroster. Don't ask me why, but I suspect lawyers were involved.Also, air and water can get into the A/C system. That can reduce the efficiency of the system and also lead to corrosion that causes damage. San Diego drivers should periodically purge the system and replace the refrigerant to remove the air and water.CA drivers would be wise to ... read more
