Split System Indoor Unit Icing Up

It could be a partial restriction in the refrigerant piping kinked pipe blocked strainer drier fault with electronic or mechanical tx valve if fitted.

Split system indoor unit icing up. Air conditioner freezing up is quite a natural scenario. When your ac system is low on refrigerant pressure drops causing the evaporator coil to get abnormally cold. This is the most common cause of a frozen evaporator coil. This problem can be resolved by having your refrigerant levels inspected and restored.

The most common one is that your refrigerant levels are low. This will affect the flow of cool air to your interiors. Change your air filter and then wait for any ice to melt before you turn your system back on. You will notice that there is less airflow coming from the air ventilation as ice began to clog the air movement.

If ice forms again call a professional for help finding the problem. We recommend never turning the thermostat below 70 degrees when running your air conditioning. Sometimes you may notice that your air conditioner freezes up after some time of operation. So when returning air hits the coil humidity moisture from the air beads ups on the coil and quickly freezes.

Refrigerant in part transfers heat from the indoor coil and once warm moves to the outside coil where it dissipates heat into that coil. I recently had two new shinco 12 000 btu mini split units installed side by side. Spitting water has the same cause as a unit that ices up slightly short of refrigerant usually. It is possible to ice up the indoor coil however if the air conditioner is running in very cold weather or if the thermostat is turned down extremely low.

Since it got cold out one unit has been constantly having so much ice build up in the fan area the fan blades hit the ice and make an awful noise. At some point an ac unit may freeze up when the balance between maintaining coolness at home and making sure that the machine is functioning is not kept. A dirty air filter could keep air from flowing over your evaporator coil fast enough to prevent ice. When this happens the cool air will not be discharged properly and eventually a huge block of ice may built up on the evaporator coil.

But 90 if the time with domestic splits it s crap installation. The ultimate purpose of installing an air conditioner in your home is to provide a comfortable temperature inside your home. The reason a lack of refrigerant can cause this ice buildup is due to what refrigerant itself is. This includes the indoor unit outdoor unit and interconnecting line set.
