Does the air emitting from your supply registers abruptly seem warm? Look at the indoor component of your air conditioner. This component is located in your furnace or air handler, if you use a heat pump. If there’s water seeping onto the floor, there might be crystals on the evaporator coil. The AC coil in the system may have frozen. You’ll need to thaw it before it can cool your house again.
Here’s what to do. If you can’t get the coil frost-free, Service Experts Heating & Air Conditioning is here to support you with air conditioning repair in Shreveport that includes a a 100% satisfaction guarantee.*
Step 1: Set the Air Conditioning to Off and the Blower On
To begin—switch the thermostat from “cool” to “off.” This halts chilled refrigerant from flowing to the outdoor compressor, which could hurt it and lead to an expensive repair.
Then, switch the fan from “auto” to “on.” This produces warm airflow over the frosty coils to help them defrost faster. Make sure to set the cooling mode to “off” so the air conditioner doesn’t start a cooling cycle.
It may take under an hour or the better part of a day for the ice to melt, depending on the amount of the accumulation. While you’re waiting, check the condensate pan below the AC unit. If the drain line is obstructed, it can cause a mess as the ice melts, likely creating water damage.
Step 2: Troubleshoot the Trouble
Bad airflow is a main explanation for an AC to become frozen. Here’s how to figure out the issue:
- Check the filter. Low airflow through a filthy filter could be the problem. Check and replace the filter monthly or once you see dust buildup.
- Open any sealed supply vents. Your house’s supply registers should be open always. Sealing vents reduces airflow over the evaporator coil, which can cause it to freeze.
- Look for covered return vents. These typically don’t have moveable louvers, but furniture, rugs or curtains can still cover them.
- Low refrigerant: While airflow restrictions are the most common suspect, your system could also be low on refrigerant. Depending on its age, it may have Freon® or Puron®. Insufficient refrigerant calls for skilled attention from a certified HVAC technician. H2: Step 3: Get in Touch with an HVAC Professional at Service Experts Heating & Air Conditioning
If inadequate airflow doesn’t feel like the trouble, then another problem is causing your AC freeze up. If this is what’s happening, merely letting it melt won’t take care of the trouble. The evaporator coil will probably continually freeze unless you fix the main symptom. Contact an HVAC specialist to check for issues with your air conditioner, which might include:
- Refrigerant leak: AC units continuously use refrigerant, so it shouldn’t run out. Insufficient refrigerant is a sign of a leak somewhere. Only a pro can locate the leak, mend it, and recharge the air conditioning to the correct level.
- Filthy evaporator coil: If grime builds up on the coil, air can’t reach it, and it’s likely to freeze.
- Nonfunctional blower: A defective motor or unbalanced fan can stop airflow over the evaporator coil.
