Fuses are a protection device and I guess that this is for the condenser section and compressor. If they blow right now when it is turned on would indicate that there is a short in the wiring or motor or compressor. If it trys to start and the outside fan starts and the compressor just humms and blows fuse, you have a locked compressor. Might check run capacitor or install a hard start kit and see if it will brake it loose, if not bad compressor

What is the temp of the air at the nearest vent when it comes out. then what is the temp of the air when it goes back into the return air? check your ouside fan and be certain it is clean as well and that the fan and compressor are running .
Hi, your problem is in the unit outside. Check to see if the fan is on, make sure the compressor is running also. If nothing is on, check the breaker to see if it tripped. Also, the box at the unit has 2- fuses inside behind the plastic cover you can't see unless you remove it. If the unit is off and the breaker was ok, remove the cover and replace BOTH fuses. Do all of this and let me know. If the breaker keeps tripping or blowing fuses if the unit was off, you have a componant shorted. It may be off or on and not cooling well due to a loss of freon. If it is on, hold your hand above the fan to feel the air. It should be nice and warm almost hot if its hot outside. Let me know what you find please. We can find the problem. Sincerely, Shastalaker7
The fan that blows the air blows through the heater coils before it blows through the A/C.As long as the heater doesn't come on, there is not much that can be done. ZCooking the attic room will be a problem because it is the heat rises thing, and on top(literally) of it all, the roof is radiating heat.
first look for red button neer the copper line set if has one push it second inspect thermostat wires for weed eater damage check disconnect for fuses check breaker at main panel pull disconect and remove cover check stat wire connections look at the capacitor if swelled up on top bad if all look ok put disconect in using insulated object manually push in contactor if unit comes on check for 24 volt ac on yellow stat wire to common if none stat wire could be loose at indoor unit or stat bad hope this helps you
Could be a faulty thermostat, (referring to the furnace\heater. As far as the A.C., you must have a dual thermostat with a switch for A.C. and Heating. Is the thermostat digital or mercury bulb? As for the A.C. it sounds like it is going off on high discharge pressure. Is the cooling fan running that cools the condenser? It must be spinning freely or it may be starting and because it is partially seized, it will cut off with a high current draw. Anyways, the condenser must be clear of any debris, no shrubs around it. The compressor could be bad and trying to start but goes off on overload because it isn't starting. It's start capacitor could be bad and not giving it that extra boost on start up which is what a start capacitor does. Good luck.
