Why does my AC not cool when idling?
The condenser is primarily responsible for ensuring cool air from the AC vents. If the condenser has gone bad, it will not be able to process the freon and produce cool air. A broken condenser might malfunction when there is a cut back in power as when the car is idling or running the AC purely on the battery.
Why does my AC in my car get hot when idling?
Your AC system is low on refrigerant. Since the AC compressor is driven by the engine, it doesn’t pump as much refrigerant when you’re at a stop or driving slowly. 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.
Why does my AC get warm when I stop driving?
When the car is moving, versus stopped, there is more air flow over the condenser (the heat exchanger in front of the radiator) and that airflow is essential to system operation. To maintain airflow when the car is in stop and go traffic, or is completely stopped, condenser fans will come on automatically.
What happens when your AC stops cooling?
If your air conditioner will turn on, and your thermostat is set properly, but your system is not cooling you may have a dirty or blocked air condenser.

Why does my AC stop blowing cold air when I stop?
There are a couple of reasons for ice buildup in your AC — dirty coils or filters resulting in poor airflow, or a lack of refrigerant. If that doesn’t get the unit blowing cold air again, it could be refrigerant levels are low (see below).
Why did my AC stop blowing cold air?
Can a bad thermostat cause AC not to cool?
Uneven cooling: If the thermostat is either miscalibrated or has a faulty connection to the AC, it can mean the air conditioner wonb t run long enough to distribute cooling evenly around a home. This could mean the thermostat has lost its connection to the compressor and canb t turn it on.
Why is my air conditioner not cooling my house below 80 degrees?
Well, certain problems can prevent an air conditioner from properly cooling down your home including: A dirty air filter. A blocked condenser. A refrigerant leak.
Why does the AC blow warm at idle?
Since the AC compressor is driven by the engine, it doesn’t pump as much refrigerant when you’re at a stop or driving slowly. 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. Get your system refrigerant level checked.
Why is my air conditioner not cooling as expected?
The air conditioning system is not cooling as expected. The air conditioning system may require an extended period of operation to reach the desired output. Low refrigerant level is the most likely cause of poor cooling from the air conditioning.
Why is my AC not cooling in South Florida?
If there are trees around your condenser, debris may fall from above into the casing. If you haven’t cleaned your condenser in over a year, this could be the cause of your AC not cooling. Need AC Service in South Florida? We Can Help.
What happens if your AC unit blows cold air?
During operation, the high pressure side of the refrigerant system can reach pressures of over 275 PSI. Use extreme caution when working around the A/C system. Never disconnect or vent the refrigerant to the atmosphere. Refrigerant can cause extreme frost bite or blindness if it comes in contact with your skin or eyes.
