1st check to see if the unit outside, (condenser), is running. The blower inside the furnace or air handler is responsible for circulating the air inside the house. The condenser is what makes it possible to cool the home. The condenser has two major components. The fan, which is responsible for removing the heat from the refrigerant that causes it to condense back into a liquid. and the compressor which is what pushes the refrigerant through the system. If the condenser turns on and you hear the fan, feel the air above the fan. This should be warmer than the surrounding air. If it is not, the compressor is not working. There are safety features built into the system that will shut off compressor before it gets damaged. There is a hi limit temperature switch and there also might be a low pressure switch. (this is on the newer units) If it is the hi limit temp switch, check the filter and make sure condenser coil or fins are clean. The lo press. switch on the newer units can only be checked by a certified service tech. Then try unit again. This is the only thing you can really check without calling a technician. If condenser does not turn on @ all, check the circuit breaker or fuse in the electrical panel, or check the box behind the condenser that feeds the unit electrically. There might be fuses in there that have blown. replace the fuses. Also I have run into the lo voltage wires were cut going to the condenser. The unit will never turn on if these wires are cut. They are very thin and can be cut by a rodent or a weed whacker. Good luck.

First: verfiy your air filter is clean. If you have not done any maintenence your Condensor Coil(outside, it has a fan, compressor etc.) is likely dirty and it will affect performance. You can clean it yourself with your garden hose, just be sure to shut system off before washing the condensor, avoid spraying the fan motor directly with the water.

assuming the system is sized correctly for the house and it is still not cooling as it usually does it may have leaked some refrigerant. Keep in mind refrigerant or as some call it "Freon" doesn't go bad, nor does it wear out...it should never have to be refilled unless of course it has leaked. If it has leaked you will want to be sure the leak has been repaired before dumping more refrigerant in.

feel free to contact me if you have any questions...

Answer 6

I assume that the thermostat is set low enough,

You may need to have a hvac repairman look at it..

Answer 7

Lint ,low freon,not enough insulation in your attic are the main causes.
