Re: on/off cooling

You will need to replace the outdoor fan and capacitor before it cause damage to the compressor. Thx RepairUSA

Why does it just blow cool air?

Check outside condensing unit. Should feel warm to hot air blowing out of the top. If cool to outside air temperature blowing off you likely have a refrigerant problem

I have a digital Honeywell thermostat that has a blinking snowflake. When the thermostat is on auto mode it does not turn on. When I turn the thermostat to fan I can feel and hear the air blowing out of...

If the thermostat has a blinking snowflake then it is in time delay mode which sometime can take between 5 to 7 minutes before it will turn the AC and Fan On......Then it will go to a solid snowflake.
When you turned it to fan On it starts the Fan right away..... After the snow flake has went to solid check to see if the fan is running and then look outside to see if the Fan Blade is turning on the AC..... The fan blade comes on the same time as the compressor does. Then with the fan running hold your hand above the air stream above the AC and if you can noticeablely feel warm to hot air comeing out the Top then the compressor is running also. If the outside unit is not running I would check to make sure the Main Breakers are turned ON.... After the AC has ran for a few minutes feel the copper lines that go into the house the smaller line should feel warm to hot and the bigger lines with insulation on it should feel cool to cold and sweating with beads of moisture on it..... That is a quick test to see if the unit is working properly.....If you have a Thermentor and can Check the Temperature of the Return Air and the Supply Air .. You should have about 20 Degree F Between the Supply and Return........ 75* Return - 55* Supply would Equal 20* TD Across the Coil......
That is about all you can do to check on your own....... If the compressor is not coming on or the lines are not the temperature difference then you will need to get professional help for your Air Conditioning System..... Goood Luck Hope this Helps.........

Central air conditioning system is blowing warm air.

many, many. Is the outside unit running? If it is, is the compressor running? Feel the refrigerant lines leaving the unit. Little one should be warm. Big one should be cold, probably sweating.

It is freezing inside, and it is not cooling properly

Welcome to FixYa,
Check the Following
Is your filter clean? Look and the evaporator in the inside unit. Is it frosted up? Do you have condensation water in the pan? Go to the outside unit and feel the air coming out of the fan. Is it warm? Now feel the 2 copper pipes coming out of the unit. Is the small one warm or hot? Is the larger one cool ? Is there moisture on it?
Air conditioner runs but doesn't cool at all
If the airflow is good and the air coming out is not cold, your home air conditioning problem may be a temporary problem - your coils may have frozen. Turn the unit off for an hour to let them thaw, then try again. If cold air is now present, freezing coils were the problem; if the problem recurs soon after turning on, you may need to replace the coils. Again, call a pro. If you have ceiling vents in upstairs rooms and the air flowing from them is consistently warm, you probably have leaky or poorly insulated ductwork in your attic. See my Attic ceiling insulation page for more information on insulating ductwork that runs through attics.
Another likely home air conditioning problem if you have good airflow but no cooling is that thebreaker to the outside unit is shut off, which, depending on the installation, can either cause the air conditioning system to not run at all, or to appear to be running but not provide any cooling. If you can hear the compressor fan running outside, the breaker is on, but if the outside unit is silent the outside breaker may be off. If switching it on does not solve the problem, look for the high pressure cut outon the condenser and try resetting that.

My unit is running but not blowing cool air. I went outside and the condenor fan was not moving. Took a stick and shoved a blade and the fan started moving but the air is still not cool inside. I did...

Sometimes on new units it is common for the fan to not start until you give it a push. Did you happen to hear if the compressor was operating? If the unit was froze-up the Insulated Suction line would also be iced over as well. If it wasn`t it is more likely that either the compressor was not operating or it shutoff due to
high discharge pressure and can only be reset on its
own or cooling the compressor off with cold water.

My Carrier Home AC unit stopped blowing cold air today. I opened it up and cleaned everything and didn't notice anything out of place, any ideas?

This could be complicated to resolve over the internet but I'll give it a try. When you stated that it stoped blowing cold air, did it stop blowing air all together? Also is the outside unit rtunning?

Is the outside unit running? if so can you feel warmer than outside air blowing from outside fan? If not your system may have a leak and pressures low. You can also check the piping to and from the unit larger one should be cold small one should be warm

Bryant Legacy Line air conditioning not blowing cool air..

Your outdoor condenser is in heat mode. Check the wires on the thermostat. Sounds like a small wiring problem and nothing else. Good luck. Please keep me posted as to you progress.

Carrier Air Conditioner, cool air then runs luke warm air

Have you checked the freon level in this unit? If you are low or there is a leak it could be the problem. Hope this helps.
