Air Conditioning ProblemsOne of the most common air conditioning problems in South Florida is a frozen evaporator coil, which happens when the evaporator coil cannot absorb heat correctly and its temperature drops below freezing, turning any condensed moisture on the coil into ice. Not only does this prevent the system from cooling properly, it can also cause permanent damage to certain components. To get the system running properly, you will have to determine the cause, correct it and thaw the coil.

Airflow Problems

In many cases, poor airflow can prevent the coil from absorbing the heat in your home, allowing it to freeze up. Reductions in airflow can be triggered by a dirty or clogged air filter, an obstructed supply or return duct, or problems with the blower fan. Replace the air filter, if necessary, and check your air ducts for obstructions. Make sure none of the vents are covered by furniture, curtains or other items. Check the blower fan and make sure that it is relatively clean and operating correctly, and that its belt is not damaged or slipping.

Dirty Evaporator Coil

Household dust, pet hair and other debris can accumulate on the evaporator coil over time and prevent it from absorbing heat properly. If your evaporator coil is excessively dirty, allow it to thaw, then clean it gently using a soft brush and a vacuum cleaner, being careful to not bend any of the delicate cooling fins.

Refrigerant Problems

Low refrigerant levels, leaks or a clog in the lines can also cause major air conditioning problems like freezing. To correct a refrigerant problem, or any other serious issue, you will need to call a professional.

Thawing the Coils

To thaw the evaporator coils, turn off power to the system and allow the ice to melt naturally. To speed things up a hair dryer or heat gun can be used in a pinch, but never use tools to remove ice, as they may damage the refrigerant lines.
