Hi, Does thermostat on a/c goes lower than 75? put hands close to air coming from a/c is it cold, like 50, if it's cold like 50, maybe you a/c are to small for space, check a/c b.t.u's ( british thermal units) how many b.t.u's is your a/c , there are a chart, for size of room and how many b.t.u's you'll need to cool space (room), or possible if air coming from a/c are 75, your compressor could be short cycling, it hard to tell when fans are working, listen carefully to hear if compressor makes clicking sound, place thermometer close to a/c vent and let me know temp, maybe there's freon leak. let me know temp of air coming out from a/c, then i could tell you exactly what's problem. good luck.

it is ok to run your fan continously. constant air filtering as long as it pauses before a/c cycles on. will not use any more electricity than a toaster. is there a fan programing feature on t-stat. if so you will need to turn programing to fan off

How old is your system?
If your system is a heat pump and is failing to keep up overnight during the colder weather. Or if it struggles to keep up at all, a few issues come to mind.
Obviously, the first and most common cause would be due to an undercharge of refrigerant. With an undercharge, your heat pump has lost efficiency and cannot properly remove heat from outside.
Other possible issues that come to mind are failed defrost cycle. If your unit is not defrosting properly and it continues to run non-stop, a freeze-up could occur on the outdoor coil. And the worse it gets, the worse your system will perform.
Another possibility is auxiliary heat or heat strips are not coming on at all. Depending on your thermostat, you would be able to tell if the thermostat is calling for auxiliary heat. If you are not getting any additional heat, then the heat pump may not be adequate for the space intended.
Other smaller factors may come into play such as incorrect defrost cycles. Possibly a mechanical component taking a break or overheating or maybe a mechanical failure such as failed compressor leaving the only heat you have as emergency.

I would remove front cover and see if your thermostat has a mercury switch.this will be a small vial connected to a bimetallic coil. The vial wiil be about 1/3 full of mercury. It will have a brite silverey appearence.There shoul be two leveling peg on inside of thermostat. Check the level with a torpedo level. it should be very close to level. If not loosen mounting screws that hold stat to wall and gently move base till you have it level. Hold base steady and tighten mounting screws. This should help thermostat setting and actual temperture to be closer. It's not unusual for setting to be off by several degrees.
