What is the likely cause of an air conditioner that is not blowing cold air?
If your central AC is not blowing cold air, the refrigerant may be the problem. The unit could be running low and need additional refrigerant added. The most likely cause of this is a leak. A leak not only keeps the AC unit from cooling properly, but also it can cause other issues within the home.
What does it mean when your car only blows hot air?
The most common cause of an AC system blowing warm air is a lack of refrigerant, though, you may also have a problem with your condenser. Other possibilities include a faulty compressor, broken cooling fans, or an issue in your electrical system.
Why does my AC go from cold to hot back to cold?
If your A/C flip-flops from hot to cold and back again, your expansion valve could be failing. The expansion valve removes pressure from liquid refrigerant to allow expansion from a liquid to a vapor state in the evaporator. If the valve is blocked, the refrigerant flow could be restricted or could be too unrestricted.

What to Do When Your Air Conditioner Isn’t Blowing Cold Air
- Check the Thermostat Fan Setting. Is your air conditioner blowing cold sometimes but warm at other times?
- Replace Your Filter.
- Inspect the Outside Unit.
- Check Your Thermostat.
- Check Your Air Filter.
- Make Sure There is Electricity Going to Your AC.
How do I fix my air conditioner not blowing cold air?
Try cleaning your air conditioner’s filter and the coils to see if improving the airflow fixes the problem. If there is ice buildup, you’ll need to run the unit with just the fan in order to melt it off. If that doesn’t get the unit blowing cold air again, it could be refrigerant levels are low (see below).
Is your car’s a/C blowing warm air in the summer?
When it is not, which of course occurs on the most brutally hot day of the year, the A/C suddenly becomes a cruel joke, blowing warm, stale air into your vehicle. If your air conditioner is blowing warm air, or just not working properly, it is best to schedule a service ASAP to maximize your comfort.
Why is my air conditioner blowing out warm air?
If your air conditioner is blowing warm air, or just not working properly, it is best to schedule service ASAP to maximize your comfort. Automotive A/C systems have certain intricacies in their design that render them difficult to repair without the proper equipment and knowledge base.
Why does my car freeze up when I Turn Off the AC?
Check for puddles under your car soon after you shut it off. A big puddle could indicate icing. You could also have low refrigerant. A visit to your local AC shop can quickly, and relatively inexpensively, identify (fixing costs extra though) that problem. Let’s hope for icing, it’s a cheaper fix.
Why does my evaporator freeze up when I turn the blower off?
If low air flow caused it, the evaporator would freeze up every time you turned the blower speed down. The cause is low refrigerant level. Low refrigerant level reduces the pressure on the low side of the system.
