Quick Steps to Repair a Frozen Air Conditioner

Does the air emitting from your supply registers abruptly appear warm? Look at the indoor component of your air conditioner. This part is situated in your furnace or air handler, if you rely on a heat pump. If there’s water seeping onto the floor, there could be ice on the evaporator coil. The AC coil inside the unit could have frosted over. You’ll need to thaw it before it can cool your residence 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 Calgary upheld by a 100% satisfaction guarantee.* 

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

To get started—move the thermostat from “cool” to “off.” This stops chilled refrigerant from going to the outdoor compressor, which could hurt it and cause an expensive repair. 

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

It can take less 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 might create a mess as the ice melts, possibly causing water damage. 

Step 2: Diagnose the Situation 

Not enough airflow is a chief reason for an AC to frost over. Here’s how to get to the bottom of the situation: 

• Check the filter. Inadequate airflow through a dusty filter could be to blame. Check and replace the filter monthly or as soon as you see dust accumulation. 
• Open any sealed supply vents. Your residence’s supply registers should stay open always. Sealing vents limits airflow over the evaporator coil, which might cause it to freeze. 
• Check for covered return vents. These usually don’t come with adjustable louvers, but furniture, rugs or curtains can still obstruct them. 
• Insufficient refrigerant: While airflow restrictions are the most typical culprit, your system may also not have enough refrigerant. Depending on how old it is, it may use Freon®. Low refrigerant necessitates pro attention from a certified HVAC specialist. H2: Step 3: Get in Touch with an HVAC Specialist at Service Experts Heating & Air Conditioning 

If inadequate airflow doesn’t appear to be the problem, then another problem is leading your AC freeze up. If this is what’s occurring, just thawing it out won’t repair the problem. The evaporator coil will possibly freeze again unless you take care of the underlying symptom. Call an HVAC tech to check for issues with your air conditioner, which could include: 

• Refrigerant leak: AC units continuously use refrigerant, so it shouldn’t run low. Low refrigerant indicates a leak somewhere. Only a technician can locate the leak, fix it, and recharge the air conditioner to the proper concentration. 
• Filthy evaporator coil: If dust builds up on the coil, air can’t get to it, and it’s liable to freeze. 
• Malfunctioning blower: A bad motor or unbalanced fan can prevent airflow over the evaporator coil.
