Why Is There Ice on My AC System?

You’ve noticed a slick sheet of ice on your AC system. Now what? Many homeowners might assume this isn’t a big deal — is ice even a bad thing when the whole point of your AC is to keep things cool? 

Unfortunately, ice is almost always a sign there’s something wrong with your system. Learn what ice on your system could signal and whether it means it’s time for AC repair in White Plains.

Low Refrigerant Levels

Refrigerant is the substance that gives your system the ability to cool the air in your home. When refrigerant levels are too low, it can cause the evaporator coil’s temperature to drop below freezing. The result is the moisture freezing on the coil instead of falling into the collection pan.

This usually means that your system has sprung a leak. If you suspect the cause of your ice is low refrigerant, turn off your system and call a professional HVAC technician for AC repair in White Plains. This will help prevent any further damage to the components. 

Unclean Evaporator Coils or Air Filters

Dirt can easily prevent your HVAC from performing its duties. It can block air that would otherwise blow over the evaporator coil, causing the system to perform almost the same way it does with low refrigerant levels. 

The good news is that there’s something you can do about this right now. Check your air filter and clean it if it’s dirty. Let the ice fully melt, then turn the system back on. If the ice comes back, then either the dirt is on an internal component you can’t access, or it’s another issue altogether. Avoid any ice buildup in the future by cleaning or replacing your air filters every one to three months.
