When the heat goes up, a properly working air conditioning unit in your car becomes a must for both comfort and safety. A situation that is quite common for a lot of car owners is that their AC vents, even with the system being on, put out warm air! This issue usually points to the fact that your AC system is low on refrigerant. Continue reading to learn the signs of refrigerant deficiency, the ways to diagnose the problem, and the steps our pros take to fix it. Also, we will present some preventive maintenance tips to keep your AC system running without a hitch.
Signs of Low Refrigerant
The very first thing that has to be done when dealing with low refrigerant in your vehicle’s AC system is to spot the signs. One of the most conspicuous signs is that your AC blows cold air when you drive, but not when the car is stationary. This difference in cooling suggests that your system might be low on refrigerant. Another sign is if your AC takes really long to cool down, and it’s already warmed up at the engine.
You can check those signs by switching on your AC and letting it run on the highest fan speed. Warm up your engine for a couple of minutes, then get a temperature gauge and measure the air coming from your vents. If the air temperature does not really go down after a couple of minutes, that is a definite sign that your system could be low on refrigerant.
Diagnosing the Issue
A low refrigerant diagnosis is done through the following steps. The first step is to find the low-pressure side port on the AC system in question. Typically, this port has an “L” indicating it and is going to be the very spot where you will be connecting the refrigerant canister. Set the fan speed to the maximum on your AC, and switch the unit on. The refrigerant must be in a state of thorough mixing, and this can be accomplished by allowing it to escape slowly while the pressure gauge is being watched. The green zone for the pressure gauge is what generally shows the correct level. Caution is necessary to avoid overfilling because it may cause other problems.
When the recharging is done, it is a good practice to keep an eye on your AC system to determine if the issue has been fixed. If the AC gives cold air for a day or two and then starts blowing warm air again, it is likely that there is a leak in your system. Leaks most often occur in the areas of the ports, fittings, and the condenser. Regular inspections and maintenance not only allow you to be proactive but also give you the assurance that problems won’t arise and your AC system will be operating smoothly.
Tips For Preventive Maintenance
Preventive maintenance is factor number one in keeping your air conditioning system in perfect condition. Our pros will inspect your AC Belt to determine whether it has the right tension or not. The slipping of an old belt will not allow your AC compressor to work properly, causing warm air to pass through the vents. In addition, we will inspect your compressor, evaporator, receiver dryer, and other components of your air conditioning system for any sign of wear or tear.
Providing good care for your AC system also requires you to pay attention to the O-rings and all fittings. These parts can break down and develop leaks after a while. We suggest scheduling periodic inspections so that any problems are laid bare early enough, avoiding larger issues later on.
Common Leak Areas
The loss of refrigerant from your AC system may be due to a number of places where leaks commonly occur. Ports and fittings are one of the most likely spots where leaks happen. Fast-forward to refrigerant leakage from these areas, which usually have O-rings that degrade over time. The condenser, placed at the front of the radiator, is, however, another area that can leak refrigerant, being a common place for leaks.
That being said, the friction between the AC lines and metal surfaces can grow to a point where the lines are damaged and leak. Also, the evaporator located at the back of the dashboard and the receiver dryer may also become potential leak sources. However, regular inspections of these two elements can also help in controlling the leakages before large issues arise.
