Quick Steps to Fix a Frozen Air Conditioner

Does the air coming from your supply registers suddenly appear hot? Check the indoor portion of your air conditioner. This part is housed inside your furnace or air handler, if you use a heat pump. If there’s water seeping onto the floor, there may be ice on the evaporator coil. The AC coil within the system might have frosted over. You’ll need to defrost it before it can cool your residence again. 

Here’s the things you should do. If you can’t get the coil defrosted, Service Experts Heating & Air Conditioning is here to help with air conditioning repair in Fort Lauderdale backed by a 100% satisfaction guarantee.* 

Step 1: Set the Air Conditioning to Off and the Blower On 

To get started—move the thermostat from “cool” to “off.” This halts chilled refrigerant from going to the outdoor compressor, which could damage it and lead to a pricey repair. 

After that, switch the fan from “auto” to “on.” This creates warm airflow over the crystallized coils to make them thaw faster. Remember to set the cooling mode to “off” so the air conditioner doesn’t begin a cooling cycle. 

It might take not more than an hour or most of the day for the ice to defrost, depending on the amount of the buildup. While you’re waiting, watch the condensate pan underneath the AC unit. If the drain line is blocked, it could create a mess as the ice melts, potentially causing water damage. 

Step 2: Diagnose the Situation 

Not enough airflow is a main cause for an AC to frost over. Here’s how to get to the bottom of the issue: 

• Exmaine the filter. Inadequate airflow through a filthy filter could be the problem. Check and put in a new filter each month or once you see a layer of dust. 
• Open any shut supply vents. Your house’s supply registers should remain open always. Sealing vents decreases airflow over the evaporator coil, which could cause it to freeze. 
• Be on the lookout for covered return vents. These usually don’t have shiftable louvers, but furniture, rugs or curtains can still obstruct them. 
• Low refrigerant: While airflow restrictions are the most frequent suspect, your air conditioning might also have insufficient refrigerant. Depending on when it was installed, it may use Freon®. Low refrigerant requires skilled attention from a certified HVAC technician. H2: Step 3: Get in Touch with an HVAC Technician at Service Experts Heating & Air Conditioning 

If poor airflow doesn’t feel like the issue, then another problem is causing your AC freeze up. If this is the case, simply letting it melt won’t repair the problem. The evaporator coil is likely to continually freeze unless you fix the main issue. Contact an HVAC tech to check for troubles with your air conditioner, which may include: 

• Refrigerant leak: AC units keep using refrigerant, so it shouldn’t get used up. Not enough refrigerant indicates a leak somewhere. Only a tech can locate the leak, repair it, and recharge the air conditioning to the proper concentration. 
• Dirty evaporator coil: If dirt collects on the coil, air can’t reach it, and it’s likely to freeze. 
• Malfunctioning blower: A faulty motor or unbalanced fan can halt airflow over the evaporator coil.
