Quick Steps to Repair a Frozen Air Conditioner

Does the air flowing from your supply registers abruptly feel not cold enough? Inspect the indoor component of your air conditioner. This piece is situated in your furnace or air handler, if you have a heat pump. If there’s water dripping onto the floor, there could be crystals on the evaporator coil. The AC coil in the equipment may 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, Norrell Service Experts is here to help with air conditioning repair in Birmingham upheld 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 halts chilly refrigerant from moving to the outdoor compressor, which could hurt it and result in a pricey repair. 

Then, move the fan from “auto” to “on.” This makes heated airflow over the crystallized coils to make them thaw faster. Make sure to set the cooling mode to “off” so the air conditioner doesn’t start a cooling cycle. 

It may take less than an hour or the majority of the day for the ice to defrost, depending on the amount of the buildup. While you’re waiting, check the condensate pan under the AC unit. If the drain line is blocked, it can cause a mess as the ice melts, possibly creating water damage. 

Step 2: Diagnose the Trouble 

Insufficient airflow is a primary cause for an AC to become frozen. Here’s how to figure out the situation: 

  • Exmaine the filter. Low airflow through a dusty filter could be the issue. Look at and change the filter once a month or once you see a layer of dust. 
  • Open any closed supply vents. Your house’s supply registers should remain open constantly. Closing vents limits airflow over the evaporator coil, which could cause it to freeze. 
  • Check for covered return vents. These typically don’t have shiftable louvers, but furniture, rugs or curtains can still block them. 
  • Low refrigerant: While airflow restrictions are the most frequent suspect, your air conditioning might also be low on refrigerant. Depending on when it was replaced, it may use Freon®. Insufficient refrigerant calls for pro help from a certified HVAC specialist. H2: Step 3: Get in Touch with an HVAC Specialist at Norrell Service Experts 

If low airflow doesn’t feel like the trouble, then another problem is causing your AC frost over. If this is what’s happening, merely letting it melt won’t fix the problem. The evaporator coil is likely to keep freezing unless you take care of the underlying symptom. Call an HVAC specialist to address problems with your air conditioner, which could include: 

  • Refrigerant leak: AC units recycle refrigerant, so it shouldn’t run low. Insufficient refrigerant means there’s a leak somewhere. Only a specialist can pinpoint the leak, fix it, and recharge the system to the appropriate amount. 
  • Dirty evaporator coil: If dirt builds up on the coil, air can’t reach it, and it’s apt to freeze. 
  • Malfunctioning blower: A defective motor or unbalanced fan could prevent airflow over the evaporator coil.
