Best Murrieta Car Air Conditioning Repair and Maintenance

As summer is fast approaching, it is a good idea to consider your car’s air conditioner. It is so important that it is in good condition for the heat of summer, not only for your comfort but also for your health.


Contrary to what some people believe, an auto air-conditioner system does not simply blow cold air into the car. The car’s air conditioning system is actually designed to remove the hot air from within the vehicle cabin and dispel it outside the car.

In order to do so, the air conditioning system relies on a number of components to operate effectively.


These items are prone to wear and regular system servicing helps to protect them from breakdown:


  • Refrigerant:  The refrigerant carries the heat away from 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: The compressor takes low-pressure, cool refrigerant and compresses it and circulates the refrigerant in the system.

  • Evaporator: This is like a radiator that works in reverse; instead of radiating heat, it absorbs it. This transfers heat to the refrigerant from the air blown across it, cooling your car.  

  • Condenser: The condenser removes heat from the high-pressure refrigerant gas, enough to cause the gas to condense and become a liquid and expels the heat from the car.

  • Expansion valve (or orifice tube in some vehicles): The expansion valve restricts refrigerant flow to maintain high pressure upstream between it and the compressor. As refrigerant sprays through the valve's orifice into the evaporator, it turns from a liquid into a gas, thereby absorbing heat.

  • Receiver/dryer: Once the refrigerant turns into a liquid, it's stored in the receiver until needed. While there, it passes through a filter to remove dirt and through desiccant to remove water. ​




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


The best way to tell if your air conditioner has a problem is if it can't generate or maintain air temperatures that are 50 degrees Fahrenheit below the ambient outside air temperature. The most common cause of a malfunctioning air conditioning unit is a low level of refrigerant. This could be caused by a leak somewhere in the system.


Since modern air conditioning systems are complicated, it's best to have a professional check out the problem. Any air-conditioner problem that involves opening the pressurized system to the atmosphere should be left to the pros, who have the expensive tools and expertise needed. Early detection of leaks or damage to your vehicle AC system can save you time and money, keeping you and everyone in your vehicle cool and worry free.


Loud Screeching or Rattling:


If you hear loud screeching that's continuous or happens when you start your car along with a loss of cooling and other symptoms such as rattling or poor air flow from the vents, this can spell the difference between a major repair like an A/C compressor, or a minor one like a bad blower fan.

As professional mechanics and the best Murrieta air conditioning repair, when you come to us with these symptoms, the first thing we check for is a broken V-belt and replace if necessary. This might resolve everything.


If we find the compressor spins but the clutch doesn't engage, we will check the fuses in the main panel and also check for a broken clutch wire. If compressor will not turn, there could be several issues we need to troubleshoot.




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 make sure both are working.  


Tips For Maintaining A Car Air Conditioner


There are many other possible causes to a non-working air conditioner as well. Here are some simple ways you can check on your vehicle’s air conditioning system periodically and be more proactive in recognizing any problems.


  • Run the air conditioner once a week for about ten minutes. This will maintain gas pressure to keep the compressor working properly. Also, it ensures that the many hoses, valves and pumps throughout the system are kept well lubricated. When you do this, be sure to turn it to its highest fan speed and coolest setting.

  • Run defrost mode for about five to ten minutes. This prevents mildew and cleans out excessive moisture, which can lead to unsavory odors in your car.

  • Use your air conditioner in the winter. In addition to cooling your vehicle, one of the air conditioner’s primary functions is to remove humidity from the cabin. It works especially well when you need to remove fog from the windshield to improve visibility.

  • Re-charge your air conditioning system. Every two years refresh the cooling system with gas and lubricant.

  • Whenever you have the car serviced, make sure you ask the mechanic to check the refrigerant level and regas the system if necessary. It is good practice to get a full air conditioning service at least once a year. Try and do this before the hotter months start, as this will ensure that you are not caught by surprise with no air conditioning during a sudden heat wave at the start of the season.

  • Recirculated air takes the cooler air from inside the cabin and reprocess it through the receiver dryer. The receiver dryer takes more moisture from the air and pushes colder air into the cabin.

  • The coldest setting on your air conditioning is the lowest fan speed (probably 1) with the air on recirculating. Not only will you get the coldest air possible, but you’ll also find that the air conditioning compressor won’t need to operate as often. The end result is that you’ll achieve better fuel economy in your car as the engine isn’t working as hard.


Newly Purchased Car? Here’s The Best Way To Break In Your A/C System


For a newly purchased, newly delivered vehicle, here’s the correct way to use the vehicle air conditioning system for the first time (This is also good practice for when you’ve been parked under the hot sun for several hours):


Open a couple of windows a bit (half way down is good) and put the fan blower on high with the dial set to fresh air. This pushes out the hot air in the car and cools the interior quickly. After a couple of minutes, close the windows and let the air conditioning system lower the interior temperature.


Then after the interior starts to cool down, reduce the fan speed from high to a lower speed. You’ll notice the temperature drop again. Only when it starts to feel comfortable, change the dial from fresh air to recirculating air.
