As the “heart” of the A/C system, the compressor performs a critical duty in the cooling of your vehicle. A compressor is a rotating pump which circulates refrigerant throughout the A/C system. Symptoms of a bad A/C compressor include: The A/C compressor won’t turn on, or stutters on and off The A/C is blowing warm
Automotive air conditioning is a self-contained system which cools the cabin of a car by changing the phase of refrigerant from gas to liquid and back again by applying and releasing pressure on it. Each part of the system is connected by tubing or hoses which form a closed loop through which the refrigerant flows.
Refrigerant and DIY tools for Automotive A/C repair are readily available at any auto parts store. While this “ease of access” somewhat translates into “ease of use,” it is imperative to be aware at all times of the potential risks of working on an A/C system and to minimize those risks from the get-go. Be
As always, FJC is on the forefront of many exciting innovations in the automotive aftermarket air conditioning market. We have integrated the ideas of the most forward-thinking people in our industry to create new products, and improve existing products, to better meet the changing needs of the automobile A/C industry. In this post we will
As electric and hybrid vehicles continue to gain in popularity, we have been receiving an increasing number of inquiries regarding OEM requirements, safety precautions and general procedures regarding the A/C evacuation, recycling, and charging procedures on these vehicles. In 2020, in addition to knowing whether your vehicle’s A/C system uses R-12 refrigerant (pre-1996 model year
An A/C filter, or cabin air filter, is a simple but important element of a mobile A/C system. The filter helps maintain air quality within the vehicle cabin. It does this by removing contaminants such as dust, dirt, smoke, pollen, mold and bacteria as the air flows into the cabin. As is typical with filters,
No. No, it’s not. A properly functioning vehicle air conditioning system is absolutely crucial to maintaining a cool and comfortable interior cabin, especially during the heat of summer. That’s why when things start to go wrong, we are so impatient to get it back to peak performance. Unfortunately, the A/C is often a “forgotten system”
Under normal conditions you should never have to recharge you automotive A/C with refrigerant. The system is, after all, a closed loop through which the refrigerant flows ad infinitum. So what does it mean if your system starts blowing warm air? If the warming of your AC output has happened slowly over time, it is
When a mobile A/C system needs to be repaired, the first step taken is usually to recover the refrigerant from the system for reuse later. An A/C vacuum pump is used to remove unwanted air and water vapor when it is under service. Moisture and air in the system can potentially damage the system. Air
Hot temperatures outside generally means cranking up your car’s A/C, but what if you do that and a rattling noise accompanies the cool flowing air? Hearing any sort of rattling noise from your car can cause stress and concern. A rattling sound can mean your A/C is starting to deteriorate and/or some of its parts
It may seem counter-intuitive to run your mobile A/C when the weather’s cool, or even freezing, however running the A/C in the winter not only does not do any harm to your heating/cooling system, it may in fact, offer benefits. Simply put, running the A/C and heater will dehumidify and remove moisture from the air.
Is there water pooling inside or outside of your vehicle? While there are a few potential causes, the culprit may likely be an A/C water leak. A/C water leaks are very different from the A/C refrigerant leaks that we often speak about. Read further to learn what causes car A/C water leaks and what to
We should all try to conserve fuel, whether for the environment or our pocketbooks—or both. It is with this notion in mind that we address an age-old question: Is it more fuel efficient to drive with the A/C running, or with the windows rolled down? We’ve all heard the arguments: “Opening the windows increases aerodynamic
In general, “Spark Free” tools are made of materials that do not contain iron and which utilize manufacturing processes which reduce the risk of a spark being created while the tool is in use . They protect against both fire and explosion in environments that may contain flammable liquids, vapors, dusts or residues. When working
The following checklist for inspecting an automotive A/C system has been developed from the recommendations of the Mobile Air Conditioning Society (MACS) An annual A/C inspection is recommended, ideally during the Fall or Spring seasons. Many use the change to or from Daylight Saving Time as an inspection reminder. Note: Always use extreme caution when
ABSOLUTE ZERO – The lowest theoretically possible temperature: complete absence of heat; believed to be -459.67°F (-273.15°C). AIR CONDITIONING – A system for controlling temperature, ventilation and humidity in a vehicle through condensation. Typically used to maintain a cool atmosphere in warm conditions. AMBIENT TEMPERATURE – Temperature of the surrounding air, or outside air temperature
Expansion Valves: The expansion valve is a complex valve which regulates refrigerant flow at the evaporator inlet with an internal moving rod mechanism. This rod opens and closes to differing heights based upon the cooling burden put upon the system. This process of metering modulates the flow according to the temperature of the refrigerant in
When an automotive A/C compressor failure occurs, it’s best practice to flush out the system before installing the new compressor. Many times when a compressor fails it sends small metal particles throughout the A/C system. These particles can clog up passages in the system and cause problems after you’ve replaced the failed compressor. Even tiny
Automotive air conditioning is a self-contained system which cools the cabin of a car by changing the phase of refrigerant from gas to liquid and back again by applying and releasing pressure on it. Each of the parts of the system is connected by tubing or hoses to form a closed loop through which the
Most people assume if their A/C is blowing warm that they are low on refrigerant. However, this is not always the case. Therefore, when charging A/C systems it is recommended to evacuate the system before adding refrigerant. This is because one of the most important factors in the performance of an A/C is the amount
Manifold Gauge Set Q & A What is an A/C manifold gauge set? An A/C manifold gauge set is a service tool which enables techs to keep a close eye on the pressure in an air conditioning system and regulate the refrigerant pressure flow. It is used to diagnose and correct an air conditioning unit

Winter is quickly approaching, and for many drivers that often means several months without running their car air conditioning. However, operating the AC in your vehicle during these colder months can actually prolong the life of your vehicle’s system and, even more importantly, help keep you safer on the road. Your car’s air conditioner does
Although it may not always seem like it (traffic anyone?) we sure are lucky to be drivers in 2019 when air conditioning comes standard on nearly every car sold in the US…..but it wasn’t always that way! Throughout much of the automobile’s history, air conditioning was either an overheated-driver’s dream or later, an enviable cutting-edge
