Quick Steps to Repair a Frozen Air Conditioner

Does the air emitting from your supply registers suddenly feel warm? Inspect the indoor part of your air conditioner. This part is situated in your furnace or air handler, if you have a heat pump. If there’s water leaking onto the floor, there could be frost on the evaporator coil. The AC coil inside the system might have frozen over. You’ll need to defrost it before it can cool your house again. 

Here’s what to do. If you can’t get the coil frost-free, 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: Set the Air Conditioning to Off and the Blower On 

First things first—set the thermostat from “cool” to “off.” This prevents chilled refrigerant from going to the outdoor compressor, which could harm it and result in an expensive repair. 

Next, switch the fan from “auto” to “on.” This makes hot airflow over the frosty coils to make them defrost faster. Make sure to set the cooling mode to “off” so the air conditioner doesn’t trigger a cooling cycle. 

It might take not more than an hour or the majority of the day for the ice to thaw, depending on the extent of the ice. While you’re waiting, check the condensate pan under the AC unit. If the drain line is clogged, it can create a mess as the ice melts, possibly causing water damage. 

Step 2: Diagnose the Issue 

Bad airflow is a main reason for an AC to become frozen. Here’s how to get to the bottom of the situation: 

• Look at the filter. Low airflow through a dusty filter could be to blame. Inspect and put in a new filter once a month or as soon as you observe a layer of dust. 
• Open any sealed supply vents. Your house’s supply registers should stay open always. Sealing vents decreases airflow over the evaporator coil, which may lead it to freeze. 
• Be on the lookout for blocked return vents. These typically don’t come with adjustable louvers, but furniture, rugs or curtains can still obstruct them. 
• Not enough refrigerant: While airflow restrictions are the most frequent culprit, your air conditioning may also not have enough refrigerant. Depending on its age, it may rely on Freon®. Low refrigerant calls for skilled assistance from a certified HVAC tech. H2: Step 3: Call an HVAC Technician at Service Experts Heating & Air Conditioning 

If inadequate airflow doesn’t feel like the problem, then something else is making your AC frost over. If this is what’s occurring, merely defrosting it won’t take care of the issue. The evaporator coil is likely to continually freeze unless you take care of the underlying symptom. Get in touch with an HVAC professional to check for troubles with your air conditioner, which might include: 

• Refrigerant leak: AC units recycle refrigerant, so it shouldn’t get used up. Insufficient refrigerant is a sign of a leak somewhere. Only a pro can pinpoint the leak, fix it, and recharge the air conditioner to the correct amount. 
• Filthy evaporator coil: If grime collects on the coil, air can’t flow over it, and it’s apt to freeze. 
• Nonfunctional blower: A faulty motor or unbalanced fan could stop airflow over the evaporator coil.
