The pressure before refill was around 5 psi and now its 40 psi (recommended level). Your ac system is low on refrigerant.
In this video you can find information about car
Check whether the electrical connections for the condenser fan is connected and seated firmly.
Car ac not cold while idling. If that is not working then the head pressures for the compressor become excessive and to save the compressor from damage it is shut of at the clutch at the pulley. The most common reason for now blowing cold air is condenser, when it not working, your car will not blow cold air. The ac compressor may not be pumping sufficiently at slower rpm's (revolutions per minute).
Wifes ac on 06 corolla was not blowing cold enough air so i bought a/c pro recharge kit and refilled the system. If the expansion fails to close slightly when idling the pressure. Other possibilities are that the compressor clutch is not cycling as intended or that the condenser might be blocked or dirty.
If the a/c isnt blowing cold air when the car is idling, this is an indication that there may be a problem with the ac system high pressure hose. The ac does not blow cold since i bought the truck used 1 year ago. I have noticed that while stopped the air does not blow as cold as when at speed,is this a sign of a problem with the system, low refrigerant.
There is a high chance that you have. You might also have a low state of refrigerant charge. Since the ac compressor is driven by the engine, it doesnt pump as much refrigerant when youre at a stop or driving slowly.
Now if your issue is the second case (good a/c performance when engine is cold, bad performance when engine is warmed up) that would indicate that the temperature blend door is stuck partially open. I live in dallas, at speed it blows very cold. They use a small plastic door to control the air flows into the core.
In this condition, the compressor. It seems to blow the coldest during long periods of driving fast, such as on the freeway. When driving it blows warm air.
Your a/c is not blowing any air: Your car ac relies heavily on the motor fans to circulate the flow of freon when the car is at rest. When the compressor is rotating faster the expansion valve opens more.
System at a higher rate but there isn't enough refrigerant to support the designed system pressures, being in a starvation state. If the car is moving, the air conditioning system will not require a secondary cooler. This is another reason for a car ac not blowing cold when idling.
If your car ac pauses the flow of air when idling but turns back on when you begin to move, the first place you should turn your eyes is the motor fans. Its that particular unit in your car that keeps the refrigerant cool and then flows through the blower by converting the hot air into cool air. In most cases, your a/c is fine.
When the car is a standstill, at that time condenser totally depends on the cooling fan to make it cool down. At higher rpm, the refrigerant is being pushed through the. Robert has provided sound advice.
The reason for a bad cooling fan affects the air conditioner so significantly is the fact that heat coming from freon (refrigerant) is usually cooled when it is passing from the condenser. Also when i switch on the ac i dont hear. If you are not receiving adequate air circulation from your vents, your fan is not the only thing that needs to be replaced.
The responding certified mechanic will come to your location,. The ac is now cold but only when the car is sitting idle. There will be a cooling fan in front of the condenser ( ac unit in front of the radiator) that should be running as soon as you turn the ac on.
Condensing fans are both blowing at low speed, it's about 80 degrees outside. If the system is low on refrigerant, it will show up as ac blows warm at idle and blows colder when the engine is running at higher rpms. In your car, engine coolant flow into the heater core all the time.
#2 cause of ac blows warm at idle. Is there a way to check the system is there a viewing glass to check for air bubbles, i was under the impression that if bubbles were present it had a leak and needed refrigerant. What you can do is check whether the electric cooling fan that sits beside the condenser is running.
It is also possible that there is a problem with the ac. Today i refilled the freon with a gauge and kit from a car parts store. If its not cooling at idle, but cools when you accelerate or are driving at 1500 rpm engine speed or more, than thats a pretty sure sign the system is low on refrigerant.
Once i have slowed down significantly or stopped, the air blowing out gets warmer and warmer. Your a/c only cools while driving: That air blows through the ac vents which you breathe inside the car.
Simply so, why is my ac not cold when idling? When idling the compressor is rotating slower and the expansion valve closes slightly to keep the pressure constant at the evaporator. I ran the ac for several minutes before and after filling and its still not cold.
Is car ac cooling low? If your car is not cold enough while idling, the fan just needs to be replaced. And, of course, you could have a combination of these issues.
The most common reason behind this is a condenser when it does not work properly, your car will not blow cold air. It has enough refrigerant in the system to keep the low pressure switch from tripping, when at idle. A broken condenser is another genuine cause for which your car ac may not work properly.
Basically, the air conditioning does not blow cold air if the car is idling, only when in motion. Ill assume that the heater control valv. And when your car is not moving, the condenser that is totally dependent on the cooling fan makes the vehicle cool down.
To get this resolved, the best thing to do is request an air conditioning system inspection. Heat transfer from the radiator to the condenser can alter efficiency, if the car is overheating. I checked the pressures, they are good.
