Quick Steps to Repair a Frozen Air Conditioner

Does the air coming from your supply registers unexpectedly appear not cold enough? Inspect the indoor portion of your air conditioner. This part is housed in your furnace or air handler, if you have a heat pump. If there’s water seeping onto the floor, there could be crystals on the evaporator coil. The AC coil inside the equipment could have frosted over. You’ll need to thaw it before it can cool your residence again. 

Here’s the steps you should take. If you can’t get the coil back to normal, Rob's Albertan Service Experts is here to assist you with air conditioning repair in Edmonton upheld by a 100% satisfaction guarantee.* 

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

First things first—move the thermostat from “cool” to “off.” This halts chilly refrigerant from moving to the outdoor compressor, which could hurt it and lead to an expensive repair. 

Next, move the fan from “auto” to “on.” This produces hot airflow over the frozen coils to make them melt faster. Double check to set the cooling mode to “off” so the air conditioner doesn’t begin a cooling cycle. 

It might take under an hour or most of the day for the ice to thaw, depending on the degree of the ice. While you’re waiting, watch the condensate pan under the AC unit. If the drain line is blocked, it might overflow as the ice melts, potentially resulting in water damage. 

Step 2: Pinpoint the Situation 

Bad airflow is a leading reason for an AC to freeze up. Here’s how to troubleshoot the problem: 

• Look at the filter. Inadequate airflow through a filthy filter could be the problem. Check and replace the filter each month or as soon as you observe dust buildup. 
• Open any shut supply vents. Your residence’s supply registers should be open constantly. Sealing vents limits airflow over the evaporator coil, which may result in it freezing. 
• Look for blocked return vents. These often don’t have moveable louvers, but furniture, rugs or curtains can still cover them. 
• Low refrigerant: While airflow restrictions are the most frequent cause, your system may also have insufficient refrigerant. Depending on when it was installed, it may have Freon®. Not enough refrigerant calls for professional help from a certified HVAC specialist. H2: Step 3: Get in Touch with an HVAC Pro at Rob's Albertan Service Experts 

If inadequate airflow doesn’t seem to be the problem, then something else is leading your AC freeze. If this is what’s happening, just thawing it out won’t take care of the problem. The evaporator coil is likely to freeze again unless you take care of the underlying symptom. Get in touch with an HVAC technician to address issues with your air conditioner, which can include: 

• Refrigerant leak: AC units keep using refrigerant, so it shouldn’t get used up. Not enough refrigerant means there’s a leak somewhere. Only a professional can locate the leak, fix it, and recharge the air conditioner to the correct concentration. 
• Filthy evaporator coil: If dust builds up on the coil, air can’t get to it, and it’s likely to freeze. 
• Malfunctioning blower: A faulty motor or unbalanced fan might prevent airflow over the evaporator coil.
