The air conditioner coil or air handlers can freeze up for a few reasons; but when it does there is no need to panic. Before you call the ac mechanic you could check out a few things yourself and maybe solve the problem. In case, the problem persists it is time to call the expert.
First let us check the different reasons for an air conditioner coil freezing up. It could be because the air filter is dirty and is blocking the air flow, though this is not always the most common cause but worth checking out. The other cause and also a common one, is when the refrigerant capacity is running low; this automatically builds up ice in the coil. This blanket of ice further aggravates the situation and the coil gets frozen.
The way to go about checking the problem when the coil stops functioning is find out whether both evaporator and compressor fans are working. If the evaporator fan is not running you can be sure you have found the cause for the freezing up of the air conditioner. The compressor fan alone cannot prevent the formation of ice in the inner coil – it needs the evaporator fan to do so.

Now put off the air conditioner and wait for the ice to melt, and then switch it on again. If the evaporator fan starts to run after the ice melts then it was the ice blocking the fan. However, if the fan still does not run you should call Cool Your Air.
Check for dirt or any sort of debris or mold blocking the blower blades; clean them up; check the thermostat for proper functioning; check out for any leakage. Once you can identify the problem area, the mechanic needs to work only on that specific part and it saves you money on inspection costs. All said and done, an annual maintenance of the unit can prevent undue upsets and keep the machine running smoothly.
