Air coming out of vents is 20 degrees lower than outside air. Thermostat set at 71. Temp in house is bouncing between 74 and 75. Outside temp is 90. We've never had problems before this year. Had a freon charge. Turned it on yesterday evening. Temp was 86 in house. Fan outside has been running for 16 hours. Changed filter. Cleaned coils. What could be wrong? Thanks in advance!

You should be asking these questions of the licensed service technician who charged your unit, not Yahoo bulletin board.

First go out to your compressor and see if there is ice all over the fins and coils. If so, shut the system down for a few hours until this all melts, you've had a system freezup. If there is no icing, how long has it been since that charge, if it was a while ago like several months you probably have a leak that should have been fixed by the service person who rechanrged the system. They should know better than to charge a system without finding the reason for the lost coolant and refusing to charge the system if they cannot. Call a different repair company and have the system checked again. If you just had it done it may still have leaked down, again call a different company. If they are not finding a leak at the usual places like pipe joints, you may have a hole in the condensor or evaporator and thats an expensive repair. A timed system pressure test will be able to tell them if there is a hidden leak in the system. In the absence of any leaks found during a timed pressure leakdown test, you may have a failing compressor. This too is an expensive repair.

Because your thermostat is set at 71 degrees, the unit is constantly running to achieve that temperature.
Try this; set the thermostat at a temperature of 15 to 20 degrees lower than outside temp. Once the unit reaches this temp, the unit will shut off. Then gradually lower it again to the desired temperature.
If you don't already have one, a programmable thermostat may also help.
Good luck.

Check your thermostat settings. You should, at least, be able to turn the system off. If not, you may have to kill the equipment at the electrical panel. I would call your serviceman back and watch what he does to fix your system. If it has worked like you said for years, had work done on it, then there is a problem, it is probably related.

Time for a new thermostat, for sure. Does it turn off when you put the switch on thermostat to off position but not when you raise temp. to a higher setting? If so, Thermostat is fried

Yes you may need to add more freeon, or maybe just turn it off for a little while before it freezes up. Try that, and if nothing works, call a technician.

You may need to top off the freon.
I had to do this as well....
After doing every thing you have mentioned.
