Quick Steps for Repairing a Frozen Air Conditioner

Does the air flowing from your supply registers suddenly appear not cold enough? Look at the indoor component of your air conditioner. This component is located within your furnace or air handler, if you have a heat pump. If there’s water leaking onto the floor, there may be crystals on the evaporator coil. The AC coil in the system might have frosted over. You’ll need to melt 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, Bryant Heating & Cooling Service Experts is here to assist you with air conditioning repair in Windsor that includes a a 100% satisfaction guarantee.* 

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

First things first—set the thermostat from “cool” to “off.” This halts chilly refrigerant from flowing to the outdoor compressor, which could damage it and cause a pricey repair. 

Then, switch the fan from “auto” to “on.” This makes hot 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 begin a cooling cycle. 

It may take less than an hour or the better part of a day for the ice to defrost, depending on the extent of the accumulation. While you’re waiting, keep an eye on the condensate pan underneath the AC unit. If the drain line is clogged, it can cause a mess as the ice melts, possibly resulting in water damage. 

Step 2: Pinpoint the Situation 

Low airflow is a primary explanation for an AC to become frozen. Here’s how to troubleshoot the problem: 

• Look at the filter. Low airflow through a clogged filter could be to blame. Check and put in a new filter once a month or immediately when you notice dust accumulation. 
• Open any closed supply vents. Your residence’s supply registers should stay open always. Sealing vents limits airflow over the evaporator coil, which might result in it freezing. 
• Look for blocked return vents. These typically don’t use adjustable louvers, but furniture, rugs or curtains can still cover them. 
• Low refrigerant: While airflow restrictions are the most frequent cause, your air conditioning may also not have enough refrigerant. Depending on its age, it may have Freon®. Insufficient refrigerant necessitates professional help from a certified HVAC tech. H2: Step 3: Get in Touch with an HVAC Professional at Bryant Heating & Cooling Service Experts 

If low airflow doesn’t seem to be the trouble, then another issue is causing your AC frost over. If this is the case, merely defrosting it won’t fix the trouble. The evaporator coil will possibly continually freeze unless you fix the main problem. Contact an HVAC pro to address troubles with your air conditioner, which might include: 

• Refrigerant leak: AC units keep using refrigerant, so it shouldn’t run low. Not enough refrigerant is a sign of a leak somewhere. Only a professional can locate the leak, repair it, and recharge the system to the appropriate amount. 
• Grimy evaporator coil: If dirt builds up on the coil, air can’t get to it, and it’s liable to freeze. 
• Malfunctioning blower: A defective motor or unbalanced fan can stop airflow over the evaporator coil.
