Does the air emitting from your supply registers suddenly feel not cold enough? Look at the indoor component of your air conditioner. This piece is housed within your furnace or air handler, if you have a heat pump. If there’s water seeping onto the floor, there could be frost on the evaporator coil. The AC coil in the system may have frozen over. You’ll need to melt it before it can cool your house again.
Here’s the things you should do. If you can’t get the coil frost-free, Climate Control Service Experts is here to help with air conditioning repair in Mobile that includes a a 100% satisfaction guarantee.*
Step 1: Turn the Air Conditioning Off and the Blower On
To begin—set the thermostat from “cool” to “off.” This halts cold refrigerant from moving to the outdoor compressor, which could damage it and cause an expensive repair.
After that, adjust the fan from “auto” to “on.” This makes heated airflow over the frozen coils to make them melt faster. Make sure to set the cooling mode to “off” so the air conditioner doesn’t trigger a cooling cycle.
It might take under an hour or the majority of the day for the ice to defrost, depending on the extent of the accumulation. While you’re waiting, watch the condensate pan underneath the AC unit. If the drain line is obstructed, it might spill over as the ice melts, potentially causing water damage.
Step 2: Troubleshoot the Trouble
Low airflow is a chief cause for an AC to freeze up. Here’s how to get to the bottom of the problem:
- Exmaine the filter. Insufficient airflow through a clogged filter could be the problem. Look at and replace the filter once a month or once you see dust buildup.
- Open any sealed supply vents. Your home’s supply registers should remain open all the time. Shutting vents reduces airflow over the evaporator coil, which might cause it to freeze.
- Look for blocked return vents. These often don’t use moveable louvers, but furniture, rugs or curtains can still obstruct them.
- Low refrigerant: While airflow restrictions are the most frequent cause, your system could also be low on refrigerant. Depending on how old it is, it may rely on Freon® or Puron®. Low refrigerant calls for skilled support from a certified HVAC specialist. H2: Step 3: Contact an HVAC Expert at Climate Control Service Experts
If inadequate airflow doesn’t appear to be the issue, then something else is leading your AC freeze. If this is what’s happening, just thawing it out won’t repair the issue. The evaporator coil will possibly freeze again unless you take care of the root symptom. Get in touch with an HVAC specialist to address issues with your air conditioner, which could include:
- Refrigerant leak: AC units recycle refrigerant, so it shouldn’t run low. Low refrigerant means there’s a leak somewhere. Only a tech can pinpoint the leak, mend it, and recharge the air conditioning to the appropriate level.
- Filthy evaporator coil: If dust collects on the coil, air can’t flow over it, and it’s likely to freeze.
- Broken blower: A bad motor or unbalanced fan may prevent airflow over the evaporator coil.
