The A/C works pretty well – it comes on fast and blows cold. However, after 5 – 10 minutes it stops cooling and starts blowing warm air. If I turn the A/C off, after another 5 – 10 minutes I am able to turn it on again and I can feel the compressor engage and it cools again. Could this be due to low freon? Can I fix this myself?
Why does my air conditioner keep leaking refrigerant?
The refrigerant is the lifeblood of your air conditioning unit and is akin to the motor oil in your vehicle. Although your AC technician might discover a leak during the air conditioning troubleshooting process, unfortunately it’s not usually a matter of just topping off the refrigerant.

What does it mean when your air conditioner is not working?
Air conditioner problems are not cool – low refrigerant equals low efficiency While air conditioning troubleshooting uncovers an under-performing unit, that can be the result of low refrigerant. If the refrigerant level is low, it usually means it was either undercharged at installation or it has a leak.
Why does my AC keep blowing cold air?
Hey guys, I have this problem for some time already. Most of the time my AC works great – blowing cold air as it should. But sometimes it starts blowing “normal” air instead of cold. To fix that I have to turn OFF and then ON the AC again by pressing the AC button.
Why does my car air conditioner lose its cool?
A Leak in the A/C System A small refrigerant leak is the most common reason a car’s A/C gradually loses its cool. A leak is typically caused by a mixture of moisture and refrigerant that, when combined, creates a corrosive acid that eats away at seals, valves, and hoses in the A/C system.

Why is my car AC blowing cold today but warm Tomorrow?
Blowing cold today but warm tomorrow? One of the most difficult automotive air conditioning problems to diagnose is an intermittent A/C problem. In other words, one day your car’s A/C is blowing cold air, the next day it’s warm air.
Why do I get warm air from some vents but not others?
Air from some vents and not other vents sounds more like a damper/door issue in the duct work. If you are getting warm air you can open the hood to see if the A/C compressor clutch is engaged. If not, this relay may be the culprit. When I was dealing with this issue I had warm/hot air blowing from all vents.
What should I do if my car AC doesn’t work?
The next step is to bring your car in, along with the diagnostic sheet, and have it checked out. First of all, the basics have to be right. This means ensuring that that the refrigerant system is fully charged, there are no leaks, and that the pressure readings are within the specifications.
Why is my HVAC blower not turning on?
So when calling for cooling, the thermostat usually energizes both Y for cooling, and G to turn on the blower. Since you say the blower doesn’t come on for cool calls, or when the fan switch is moved to the ON position. That points to a problem with the “fan circuit”.
Why is my Honda AC / heat not working?
It retained its class-leading handling as it, along with the fourth and fifth generations, had front double wishbone suspension, the advanced independent suspension inspired by Honda’s racing research. The ac/heat worked great until a couple days ago. I noticed the fan was not blowing any air through the vents.
What to do when your HVAC fan won’t work?
Since the blower works for heat, you might try putting the wire that’s on the HEAT terminal on the COOL terminal. If the blower fires up, you know it’s a problem with the motor. WARNING: Don’t run the system this way for long, you’re just checking to see if the blower starts.
Intermittent cooling is often caused by the components of your vehicle’s AC system freezing up. Typically an iced over evaporator is the culprit. An evaporator covered in ice can’t cool the air, so you would have to wait until the ice melts, which is why the cold air eventually returns.
Why does my air conditioner stop working after a few minutes?
There are several possible causes of a vehicle’s air conditioning system to stop working after being on for only a few minutes. Basically the causes are either the A/C evaporator is getting too cold and icing up or there’s an electrical problem causing an open circuit. Long before I knew anything about A/C.

Sometimes it will go out again after 20 minutes and sometimes it will work fine for an hour + ride.

Why does my a / C stop blowing cold after 20 minutes?
It sounds like the compressor is supplying too much pressure and the metering orifice into the heat exchanger is freezing. Exactly when it stops working, pull over safely, pop the hood and find the aluminum bottle near the back of the engine compartment. It should be covered with condensation, but I’m guessing it’ll be iced over. helpful?
