My Air Conditioner Stopped Working

IT LOOKS LIKE A HOT SUMMER

 

As we are just getting started with summer, it looks like this summer here in Murrieta is going to be a really hot one, judging from how it has started off. So, I am saying to myself, why did my car's air conditioner pick right now to stop working? I have already had extra expenses this month. So, why now? Why am I hot driving around and hot under the collar about this happening right at this very time? I think about just toughing it out and waiting until next summer to get the thing fixed. That is until the first time I get in the car to run errands and within 10 minutes I am a wilted wet mess.

So, as we are looking at car air conditioning repair here in Murrieta, let’s first look at how does a car air conditioner work? The main function of your car air conditioner, similar to your kitchen refrigerator, is to cool and dehumidify the air.

A car’s air conditioning system has 6 major components, connected by a series of tubes and hoses. So, the problem lies either with one of the components, or with the tubes and hoses.

 

Here are the 6 major A/C system components and what they do:

 

  • Refrigerant:  The refrigerant carries the heat, hopefully away from you inside the car. On newer cars, this is usually a substance called R-134a, while older cars have r-12 freon which is becoming increasingly more expensive and hard to find, and also requires a license to handle.

  • Compressor: This compresses and circulates the refrigerant in the system.

  • Condenser: This changes the refrigerant from gas to liquid and expels the heat removed from the car.

  • Expansion valve (or orifice tube in some vehicles): This is kind of a nozzle and functions to simultaneously drop the pressure of the refrigerant liquid, meter its flow, and atomize it.

  • Receiver/dryer: This functions as a filter for the refrigerant/oil, removing moisture and other contaminants.

  • Evaporator: This transfers heat to the refrigerant from the air blown across it, cooling your car.

AIR CONDITIONING REPAIR SYMPTOMS

 

When considering the hot summer weather here in Murrieta and car air conditioning repair and possible problems, one of the first things to consider is whether the fan seems to be working but the air is not cold, even when turned up high; or whether nothing at all happens when you turn on the A/C.

 

If the fan is working, but the air is not cold:  

 

Refrigerant: If the fan is working but the air is not cold, it might be the Refrigerant. The refrigerant is basically compressed and circulated throughout the air conditioning system. A mechanic can easily check to see whether the refrigerant circulation, or lack thereof, or low refrigerant level or pressure through the system is the problem.

One of the most common reasons for diminished cooling in your car is insufficient refrigerant due to a leak in the system. If the car’s A/C system has a coolant leak, you may notice your car can’t keep the interior as cool.  

 

Leaks:

If your system does leak, we will do a pressure diagnostic and leak evaluation, which will cost from 80 to 150 dollars in most cases. The technician will top it off with coolant and pressurize it, then look for leaks. Sometimes, an ultraviolet dye may be added to help the technician find small leaks.

 

Consider yourself lucky if your A/C problem originates from a lack of refrigerant due to a minor leak. Air conditioning can be pretty expensive to repair. There are a wide range of things that can go wrong. A leak or a problem with your A/C system could cost as little as 20 for replacing an O-ring to at least 1,000 for something like a compressor failure.

 

Loud Screeching or Rattling;

Symptoms of failing air conditioning components can include loud screeching that's continuous or happens when you start your car along with a loss of cooling. Other symptoms such as rattling or poor air flow from the vents can help indicate the difference between a major repair like an A/C compressor, or a minor one like a bad blower fan. Many times the problem lies in the air distribution system under the dash, not the refrigeration system under the hood.

 

Overheating:

If the engine is running hot or overheating, it can have a huge impact on your air conditioning system. Some cars have two fans, one for the air conditioning condenser and one for the radiator. We need to be sure both are working. This is a pretty simple thing to diagnose.

 

There are many other possible causes to a non-working air conditioner as well. If you have a car air conditioning problem here in Murrieta, bring the car in, we can diagnose the problem and let you know what’s going on.
