Easy Steps to Repair a Frozen Air Conditioner

Does the air coming from your supply registers suddenly feel not cold enough? Inspect the indoor part of your air conditioner. This part is located in your furnace or air handler, if you use a heat pump. If there’s water leaking onto the floor, there could be crystals on the evaporator coil. The AC coil inside the system may have frozen. You’ll need to defrost it before it can cool your house again. 

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

Step 1: Switch the Air Conditioning Off and the Blower On 

To begin—set the thermostat from “cool” to “off.” This prevents chilly refrigerant from flowing to the outdoor compressor, which could damage it and result in a pricey repair. 

Then, switch the fan from “auto” to “on.” This makes warm airflow over the crystallized coils to force them to melt faster. Make sure to set the cooling mode to “off” so the air conditioner doesn’t start a cooling cycle. 

It might take under an hour or the majority of the day for the ice to thaw, depending on the amount of the buildup. While you’re waiting, keep an eye on the condensate pan underneath the AC unit. If the drain line is blocked, it may overflow as the ice melts, likely resulting in water damage. 

Step 2: Pinpoint the Issue 

Poor airflow is a leading explanation for an AC to freeze up. Here’s how to get to the bottom of the problem: 

• Exmaine the filter. Poor airflow through a clogged filter could be the issue. Check and change the filter monthly or once you see dust buildup. 
• Open any closed supply vents. Your house’s supply registers should be open always. Sealing vents decreases airflow over the evaporator coil, which may lead it to freeze. 
• Check for obstructed return vents. These typically don’t have moveable louvers, but furniture, rugs or curtains can still obstruct them. 
• Insufficient refrigerant: While airflow restrictions are the most typical culprit, your air conditioner might also be low on refrigerant. Depending on how old it is, it may use Freon®. Insufficient refrigerant necessitates pro assistance 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 seem to be the trouble, then another problem is causing your AC frost over. If this is the case, simply defrosting it won’t repair the trouble. The evaporator coil will probably keep freezing unless you take care of the underlying symptom. Call an HVAC specialist to address problems with your air conditioner, which may include: 

• Refrigerant leak: AC units keep using refrigerant, so it shouldn’t run low. Low refrigerant means there’s a leak somewhere. Only a tech can pinpoint the leak, mend it, and recharge the air conditioning to the appropriate amount. 
• Dirty evaporator coil: If dirt builds up on the coil, air can’t flow over it, and it’s likely to freeze. 
• Broken blower: A faulty motor or unbalanced fan could prevent airflow over the evaporator coil.
