Why Your Florida Air Conditioning
System May be Freezing Over
Many homeowners in Florida are confused the first time ice or frost appears on an air
conditioner during the summer. An air conditioner that is freezing over could be suffering from
any number of serious issues that affect performance. The ice indicates something is wrong and
that the unit is not cooling the air efficiently. Most homeowners will want to call a Florida air
conditioning repair service to inspect the unit if this occurs. There are several common reasons
why an AC might be freezing over.
Air Is Not Moving
One of the primary reasons an air conditioner in Jacksonville will freeze over is because the air
is not moving through the system efficiently. This is often because of a broken fan or an
obstruction. The coils are designed to come into contact with air for only a short time. It then
moves away and into the home. If the air is not moving, then there is enough time for the
moisture in the air to freeze and accumulate on the different components. This problem could
require professional attention from a Florida air conditioning service if the fan is not operating
A refrigerant leak creates a cooling system that is forced to run under low-pressure conditions.
Low pressure means that the refrigerant cannot efficiently exchange heat from the air. The
result is freezing over. The solution is to call a repair professional in Jacksonville. The
refrigerant will need to be recharged to restore pressure. Additionally, the technician will locate
the source of the refrigerant leak so the unit stops freezing over.
The temperatures in Jacksonville can drop suddenly overnight especially if storms are moving
through the area. Running an AC in Jacksonville during this period can cause the unit to freeze
over. This is because temperatures below 60 degrees Fahrenheit combined with the cooling
cycle of the system will cause the moisture to freeze very quickly. The frozen moisture
accumulates on the coils and other parts. The best solution to this problem is to watch the
weather or raise the thermostat on the AC.
The way an AC in Jacksonville runs requires expelled water to be drawn away by a drainage
hose or other system. If the drains are clogged, then the moisture has nowhere to go and pools
under or inside of the unit. This causes the level of moisture in the air conditioner to increase.
The result is that ice crystals will start to form. Clogged drains are difficult to repair without
professional help. They could even be indicative of other problems only a technician can detect.
It is necessary to call a Florida air conditioning service at least once every year for regular
maintenance. The repair professionals will make sure the AC is in good working order. They will
also clean the coils and other components. Dirty coils in an AC that has not been maintained
are likely to freeze over. This is because the dirt on the coils acts like insulation and forces the
unit to work harder. Regular professional cleanings will prevent this from occurring.
A broken thermostat can cause an AC in Jacksonville to freeze over. The thermostat in the unit
controls when the compressor and other parts should turn off. A broken thermostat will not
deactivate the cooling system correctly. This means the air will become increasingly cooler until
the moisture eventually starts to freeze when it encounters the internal parts. An air conditioning
repair specialist can identify this problem and replace the malfunctioning thermostat
