Why would my AC stop working then start working again?
You could have a dirty or blocked condenser or a dirty evaporator. It could also be that you have a dirty air filter. These are issues that restrict the airflow through your air conditioning system and your unit is shutting down as a precaution.
Why did my AC stop working overnight?
If there is not enough air flowing through your air conditioning system, your evaporator coil will eventually freeze up and cause your AC unit to freeze up and stop working. The most common cause of this is a dirty air filter. Air flow problems can also be caused by a faulty fan or closed or blocked ducts and vents.
Why does my AC only work sometimes?
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.
What are signs that your AC compressor is going out?
Some of the signs of a bad A/C compressor are as follows.
- A Lack of Hot Air Being Released Outside.
- Loud or Strange Noises From the Unit.
- Failure of the Compressor to Turn On.
- Circuit Breaker Tripping.
- Leaks Around the Air Conditioning Unit.
- Warm Air Instead of Cool Air Being Delivered to the House.
- Reduced Airflow.
What does it mean when your AC 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.
How do you reset an AC unit?
How to Reset an Air Conditioner
- Power down your AC. Start at your circuit breaker panel and flip the breaker that powers your AC.
- Find the button. Most air conditioning units are equipped with a reset button.
- Hold down the reset button for 3 to 5 seconds and then release.
- Restore power to your AC.
Why is my AC not working in the afternoon?
Also, a dirty evaporator coil would cause low airflow and the big line to become so cold that it ices over. The small line is hot when the A/C actually works. It gets lukewarm when the A/C is running but not cooling. The fan on the condenser is working even when the A/C loses it’s cooling capabilities in the afternoon.
What to do if AC is not cooling?

Why does my AC stop blowing cold air when I stop?

What to do if your AC unit does not work?
If your AC unit still does not work, you should check to see if the breaker was tripped. There are 2 places to check: Electrical Panel – Check your main electrical panel to see if there’s a circuit breaker “tripped” (older homes use a fuse box).
Why does my air conditioner turn off after 15 minutes?
Rather than after 15 minutes, if your air conditioning unit turns on and then off immediately, you most likely have problems with the electrical components or the run capacitor. This is a common cause of short cycling and there may be an issue with the electrical supply line or the capacitor could be broken or failing.
Why is my central AC not turning on?
Check your breaker box for a blown breaker or tripped fuse. You may be able to fix this AC issue with the flip of a switch. If that doesn’t do the trick, check the wiring in your thermostat. A loose or frayed wire could also prevent your unit from turning on.
