A dirty evaporator coil can cause your air conditioning system to freeze due to decreased air flow threw the coil, it will continue to get colder and colder from lack of proper air flow freezing the condensation. It also decreases the entire ac systems efficiency.
A dirty indoor fan motor blower wheel can cause damage to the motor as it adds weight and again restricts air flow causing the motor to possibly overheat.
For a long hvac system lifespan, clean evaporator and condenser coils with a properly changed filter makes all the difference.

Why does your ac keep freezing up?
the indoor unit will freeze when there is low air flow due to a dirty filter,dirty coil, fan not spinning, or the a/c unit could be low on refrigerant charge.
Purpose of the indoor fan relay?
indoor fan relay An electric relay that starts and stops an indoor fan on cooling, electric - heating, and heat pump systems
Causes of liquid refrigerant return to compressor?
Typically refrigerant overcharge or poor heat transfer which can be due to poor air flow ( dirty filter, dirty indoor blower fan, dirty evaporator [indoor] coil, etc.). Carryover can also result in a properly operating system if there is not enough load, for example if the thermostat is set too low and the conditioned space temperature gets too low.
What is the fan blade of the AC made of?
Indoor fan = steel, Outdoor fan = aluminum.
Why does your air-conditioner spit ice?
If the system is short on refrigerant or has a leak the indoor coil will ice up and the fan will start spitting out pieces of ice, either that or the filter is really dirty.
Why does your air conditioner spit ice?
If the system is short on refrigerant or has a leak the indoor coil will ice up and the fan will start spitting out pieces of ice, either that or the filter is really dirty.
What should you do to unfreeze a central ac unit?
You simply turn the heat/cool selector lever to the off position and turn the fan switch to on. This will thaw out the indoor and outdoor coils. You are low on refrigerant, have a dirty filter, or the fan is not working properly. You should have this system checked.
If the suction side of the condensing unit has ice on it what does this mean?
Unit is not cooling properly due to loss of capacity... Usual causes: air flow restricton dirty filter or evaporator coil, loose or broken indoor fan belt, indoor fan on too low a speed setting, if it has always been present undersized ductwork should be investigated or the system is low on refrigerant.
Where to find dirty fan-fiction?
Wattpad
What component starts the indoor fan motor in an air conditioner?
contactor
Why would air conditoner freeze up?
Either the indoor coil (I assume that is what's freezing up) is getting too little airflow (bad fan, dirty air filter, clogged coil, etc.) or the unit is low on freon.
Why would you run high head and normal suction pressures?
Dirty condenser coil, high ambient temperature, problem with condenser fan, overcharge, non condensibles, high indoor load are the first places I would look. In that order.
