Quick Steps for Fixing a Frozen Air Conditioner

Does the air coming from your supply registers abruptly seem warm? Inspect the indoor portion of your air conditioner. This piece is situated within your furnace or air handler, if you rely on a heat pump. If there’s water leaking onto the floor, there might be ice on the evaporator coil. The AC coil in the unit might have frosted over. You’ll need to defrost it before it can cool your home again. 

Here’s the things you should do. If you can’t get the coil defrosted, Winnipeg Supply Service Experts is here to assist you with air conditioning repair in Winnipeg backed by a 100% satisfaction guarantee.* 

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

To get started—switch the thermostat from “cool” to “off.” This stops chilly refrigerant from flowing to the outdoor compressor, which could harm it and lead to a costly repair. 

Next, adjust the fan from “auto” to “on.” This creates warm airflow over the frozen coils to make them thaw faster. Make sure 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 the majority of the day for the ice to defrost, depending on the extent of the buildup. While you’re waiting, keep an eye on the condensate pan below the AC unit. If the drain line is blocked, it could spill over as the ice melts, possibly causing water damage. 

Step 2: Diagnose the Situation 

Low airflow is a prime reason for an AC to freeze up. Here’s how to get to the bottom of the situation: 

• Inspect the filter. Low airflow through a dusty filter could be to blame. Inspect and put in a new filter each month or as soon as you notice dust buildup. 
• Open any sealed supply vents. Your residence’s supply registers should stay open always. Sealing vents decreases airflow over the evaporator coil, which could lead it to freeze. 
• Look for blocked return vents. These usually don’t have shiftable louvers, but furniture, rugs or curtains can still obstruct them. 
• Not enough refrigerant: While airflow restrictions are the most frequent cause, your air conditioner could also have insufficient refrigerant. Depending on when it was installed, it may have Freon®. Insufficient refrigerant requires skilled attention from a certified HVAC technician.

If insufficient airflow doesn’t feel like the issue, then another problem is making your AC freeze. If this is what’s happening, just letting it melt won’t repair the issue. The evaporator coil will probably keep freezing unless you fix the main problem. Call an HVAC tech to check for troubles with your air conditioner, which may include: 

• Refrigerant leak: AC units recycle refrigerant, so it shouldn’t get used up. Low refrigerant signals a leak somewhere. Only a professional can find the leak, mend it, and recharge the system to the correct concentration. 
• Dirty evaporator coil: If dust collects on the coil, air can’t reach it, and it’s likely to freeze. 
• Broken blower: A bad motor or unbalanced fan can stop airflow over the evaporator coil.
