We have to shut it off to defrost, then it works, but why does it freeze up?

ICE Buildup on indoor coil. Heat pump. OK. From a PRO. Some simple things.
#1 You can check your filters. Lack of airflow is one cause of ice up.
#2 Low Charge of refrigerant. This is something you cannot check. If it is low on refrigerant, then you have a leak. Contrary to what some say, "freon" just doesn't disappear.
#3 You are trying to run your home below a temperature that your unit is capable of obtaining.
Simple answer - Call your local HVAC contractor. Not Billie Bob's heating and lawn care. Pay the $100 for a service call and ask questions, if you don't understand what they are telling you, let them know.
Don't run your system in this condition, you can burn up your compressor. then it is $$$$$$$, I love those calls.

It should cycle to prevent this. If freezing up the thermo sensor that signals the unit to shut off is not working and needs to be replaced. Call a pro.

you're possibly low on freon, or your filter out is clogged plenty. until eventually you're qualified to be checking rigidity I recommend no longer messing with the hot unit. you may want to study the guaranty is void in case you play round with the unit a lot. It also might want to be that they were given in a hurry even as they charged your new gadget and favor to operate a touch more effective refrigerant to the gadget.

An A/C unit will freeze because your thermostat is set way too high!!!!!! You know that knob high medium or low....use it.
