Question about Honeywell Air Conditioners
personally i'd just replace the thermostat, but try pulling the front panel off and look on the circuit board and see if there is a jumper for F/C or any other settings. you may try changing its position. you can also remove the batteries for 15 minutes and see if it resets itself. the only other thing it could be is a wiring issue.

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

When was the last time you had the coils in the condenser cleaned. Dirty coils can insulate the refrigerant tubes, causing the fan to constantly run in order to try and cool down the refrigerant returning from the evaporator coils(a-coils) in supply ducting, But can.t because the condenser coils are insulated not allowing the heat to escape. I would try this first before replacing expensive parts. It is the small things that we overlook that is most likely the source

On A/C units, there is a low voltage line that leads to a contactor, which engages to close the high voltage circuit to the condensor unit. Over time, the accual contacts in the contactor can weld themselves together. Try shutting off your furnace breaker but leaving on the one for the outside condensor unit. If it still runs, your contactor probably needs replaced. Contact a licensed electrician or HVAC contractor and tell them you think your contactor is in need of replacement. Is a fairly simple and quick replace, but the contactor itself is not cheap.

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.
