Why does my air conditioner go hot and cold?
If your A/C flip-flops from hot to cold and back again, your expansion valve could be failing. The expansion valve distributes the proper amount of refrigerant to your evaporator. If the valve is blocked, the refrigerant flow could be restricted or could be too unrestricted. Your A/C blows warm air.
How cold should the air be coming out of a window air conditioner?
If the AC system is operating correctly, then the air coming out of your vent should be about twenty degrees cooler than the regular temperature inside. So, if you’re cooling it and the house is 80 degrees, then you would ideally want the air to be about 60 degrees.
What to do when your AC blows cold air?

When vehicle is driven for a few miles, air conditioning stops blowing cold air, ie compressor clutch disengaged.
Why does my AC blow cold then blow warm?
The moisture can freeze into ice crystals right at the orifice tube or expansion valve, clogging it and stopping the flow. The symptom appears as: blows cold, then warm. If you shut off turn on the heat for a while, that’ll melt the ice crystals and the system will start cooling again. But it will still freeze up.
What happens when you turn the air conditioner down?
Moving the dial from 76° to 72° will not change the temperature of the air coming out of the registers; it just makes the unit run longer to reach the desired temperature. If your unit is already running full time to keep the house at 76°, moving the dial down will not make the house any cooler.
Why does my car AC blow cold air then blow warm air?
But that cold air turns warm fairly soon after because the high side pressures build to the point that the high pressure switch shuts off the compressor clutch. Once pressures equalize, the high pressure switch allows the compressor to start up again. The cycle repeats over and over, providing a short period of cold air, followed by warm air.
Is it better to leave your a / C on all day or turn it off?
If you have central air — or a window unit with a thermostat — you can also save energy by setting the thermostat a little higher. ACEEE estimates that air conditioners use 3% to 5% less energy for every degree you raise the thermostat. To get the best energy savings, leave your thermostat set at 78 degrees or higher while you’re out.

Is it better to turn central air off or turn it on?
Buy a programmable thermostat. Whether you turn your central air off or turn the programmed temp up when you’re out of the house, a programmable thermostat like Nest can crank up the cool factor before you get home. That way your house will be comfortable when you walk in the door.
