the heat sistem is not working well is working but 30% of eficency than it was working beafore.It hear like water on it ..help im frezzing


Air conditioning real definition is not giving cool but removing heat from the room. In same way for heating, it's not heating, removing cool from the room. When your indoor coil, air filter and blower wheel are full of dust, you won't get even 30% of cool or heat depend on your selection.
Simple solution for your problem is clean indoor unit completely. Check all sensor is working well. In heat mode keep temp minimum +3 degree than room temp. thanks and helpful.

If still no heat, check your heating sensor for closed circuit by anOHMs metre.It it's with RV, check power to RV.If it's with heatingelement check power to element. If power is there but still no heat meanselement defective. Replace new heating element. Thanks. To get proper cool, keep the tips as follows:
