Low Refrigerant
Refrigerant is a cooling chemical that helps turn the air moving through the AC unit from warm air into cold air. So, if the refrigerant levels are too low, the pressure in the system also can get too low, which in turn drops the temperature of the unit. While it might sound okay for an AC unit to be cold, the whole system is not supposed to get that way. If it does, the evaporator coil can actually freeze up and stop working.
Low refrigerant levels are not normal for a healthy AC system and could mean that you have a leak. Call our professional HVAC technicians at Royal Heating & Air to come out and take a look at your AC unit. We can inspect your system and look for any leaks or issues with your refrigerant that may be causing freezes.
Air conditioning units require airflow in order to cool your home. They don't simply blow cold air into the house. Instead, they actually pull air from your home, run it over the evaporator coil, and then blow it back into the home. The evaporator coil allows the refrigerant to absorb excess heat, which is how the air is cooled. So, if air is being blocked from flowing freely through your unit to the coil, then the coil can get too cold. This can easily cause condensation to turn to ice and freeze-up your unit.
Evaporator coils play an extremely important roll in the air conditioning process, as we've discuss. But did you know that they also help dehumidify the air? The evaporator coil pulls water out of the air, helping to dehumidify your home and make it feel even cooler. When an AC unit is working well, the water it pulls from the air drips from the coil and into a pan. If the coils are dirty, though, then the moisture they pull from the air can hang around for too long and freeze over before it can drip off of the coil.
Lack of Airflow
Air conditioning units require airflow in order to cool your home. They don't simply blow cold air into the house. Instead, they actually pull air from your home, run it over the evaporator coil, and then blow it back into the home. The evaporator coil allows the refrigerant to absorb excess heat, which is how the air is cooled. So, if air is being blocked from flowing freely through your unit to the coil, then the coil can get too cold. This can easily cause condensation to turn to ice and freeze-up your unit.
One thing that can commonly affect airflow in the home is the condition of the air filter. It is important to change the filter regularly to ensure enough air is getting through to the evaporator coil. You may need to check your filter more often if you have pets or a home that is prone to dust. You can also call the professionals in HVAC repair at the Lake of the Ozarks, and we can come check it out for you!
Residue on the Coils
Evaporator coils play an extremely important roll in the air conditioning process, as we've discuss. But did you know that they also help dehumidify the air? The evaporator coil pulls water out of the air, helping to dehumidify your home and make it feel even cooler.

If the coils are dirty, though, then the moisture they pull from the air can hang around for too long and freeze over before it can drip off of the coil.
Schedule regular air conditioner maintenance to make sure that the evaporator coils are not accumulating too much residue and dirt that could cause your AC unit to freeze-up this summer.
