Can an AC stop working when it's hot?
For some reason high temperatures are either causing too much expansion of the coolant, or there is a temperature or pressure sensor that is not working. However, by bleeding the low side pressure it can get it going again. Just be sure not to bleed off all of your coolant.

How does AC work?
AC systems work – not by cooling something directly – but by transferring heat from one place to another. In the case of a car, the heat is transferred from a heat exchanger in the passenger compartment to a heat exchanger in the engine compartment.
Why does heat flow faster in engine compartments?
Since heat flows faster if the temperature differences are greater, as the ambient temperature increases, it become s harder and harder to transfer that heat in the engine compartment heat exchanger fast enough to the outside air.
How does expanded matter absorb heat?
It relies on the principle that expanded matter absorbs heat (it’s cold) and by removing the heat from the compressed refrigerant (matter heats up when compressed) and then expanding (chilling) it, it will by using a heat exchanger absorb the heat energy from the cabin.
Does A/C work when it's hot outside?
A/C doesnot work when its hot outside. When the A/C does work it cools well. When I take the car out of garage the A/C cools well but as I start driving and if the weather outside is hot, the A/C stops cooling after some time. And it will then not cool again till I park the car in a garage and the engine has cooled down.
Why does my AC stop working?
While this setup and protective features help prevent dangerous fires from growing in the electrical system, it also means that something as simple as a blown fuse could cause your AC to stop working.
Why does my car AC keep switching back and forth?
Whenever your car AC continuously switches back and forth between hot and cold, chances are that the expansion valve is faulty. The job of the expansion valve is to distribute a certain quantity of refrigerant to the evaporator.
Why does my compressor fail?
Compressors rarely develop issues when you’re using them. The most common cause of compressor failure is inactivity – try to imagine a component that wants to work all the time or it fails. An extended period of inactivity tends to shock the component when you finally use it.
What is the job of a compressor?
The compressor is the heart of the AC and its job is to keep the refrigerant moving through the unit at all times. If it is faulty, the refrigerant cannot move through the system and you will never get anything close to cool air. Compressors rarely develop issues when you’re using them.
What happens if a condenser is not clogged?
If on inspection the condenser doesn’t look blocked or clogged, you should ensure that the copper pipes look okay. If there’s an area on the pipe that looks compressed, then it might be blocking the free-flow of refrigerant through the unit.
Why is my AC leaking?
Your AC Refrigerant is Leaking. If your car AC is blowing hot air, it is very likely that the refrigerant in the unit is low. A refrigerant is a special kind of gas (but compressed to liquid) that gives the unit its cooling ability. What it does is absorb heat from inside your car and radiate or give off the heat outside ...
How to tell if AC wire is broken?
You’ll need to inspect all the wires entering and exiting the AC to see if any wires are broken or frayed. You should also trace them all the way to the fuse box to see if there’s a broken fuse. If notice any wire that looks melted or burnt, then you’ll need to replace them and possibly change a fuse.
Why is my coolant not working?
However, by bleeding the low side pressure it can get it going again. Just be sure not to bleed off all of your coolant. 3 people found this helpful. Mark helpful.
Why does my compressor only work when it's less than 25 degrees outside?
Essentially when it got too hot outside the refrigerant would expand (as most liquids and gasses do when they heat up) which caused the compressor to think that the 'low side' pressure was higher than it should be.
How hot does a compressor blow?
It only cools when the ambient temperature is approximately 85° or lower. Above that temperature it blows extremely hot air. The compressor cuts on and off very quickly, sometimes when it's cooling but always when it blows hot. It is not low on Freon. 27 people found this helpful.
What is the low side valve?
The low side valve is the same one you would use to refill the AC refrigerant. So if you find a video on AC recharge for your vehicle it will show you where the valve is. Bleeding it from there is kind of like letting air out of a tire, your are pressing in the valve stem to open the valve to release pressure.
Can you inhale gas from AC?
So do your best not to inhale them when bleeding them from your ac system. Bleeding your ac system should be done in a manner that does not release the gas into the environment as they are considered harmful and could contribute to air pollution in large quantities. 5 people found this helpful.
