Does the air emitting from your supply registers suddenly feel not cold enough? Inspect the indoor part of your air conditioner. This component is housed within your furnace or air handler, if you rely on a heat pump. If there’s water leaking onto the floor, there might be frost on the evaporator coil. The AC coil within the equipment may have frosted 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 back to normal, Climate Control Service Experts is here to help with air conditioning repair in Mobile upheld by a 100% satisfaction guarantee.*
Step 1: Turn the Air Conditioning Off and the Blower On
To get started—set the thermostat from “cool” to “off.” This halts cold refrigerant from flowing to the outdoor compressor, which could damage it and result in a pricey repair.
Next, adjust the fan from “auto” to “on.” This creates hot airflow over the frozen coils to force them to melt faster. Double check to set the cooling mode to “off” so the air conditioner doesn’t trigger a cooling cycle.
It might take not more than an hour or most of the day for the ice to defrost, depending on the level of the ice. While you’re waiting, check the condensate pan underneath the AC unit. If the drain line is blocked, it might spill over as the ice melts, potentially causing water damage.
Step 2: Troubleshoot the Trouble
Low airflow is a leading cause for an AC to freeze up. Here’s how to figure out the problem:
- Exmaine the filter. Insufficient airflow through a clogged filter could be the problem. Look at and put in a new filter once a month or immediately when you see dust buildup.
- Open any shut supply vents. Your home’s supply registers should remain open all the time. Shutting vents reduces airflow over the evaporator coil, which can cause it to freeze.
- Be on the lookout for blocked return vents. These often don’t come with shiftable louvers, but furniture, rugs or curtains can still obstruct them.
- Low refrigerant: While airflow restrictions are the most frequent cause, your system might also be low on refrigerant. Depending on how old it is, it may have Freon®. Low refrigerant calls for pro assistance from a certified HVAC specialist. H2: Step 3: Get in Touch with an HVAC Expert at Climate Control Service Experts
If inadequate airflow doesn’t appear to be the trouble, then something else is leading your AC frost over. If this is what’s happening, just thawing it out won’t take care of the issue. The evaporator coil will possibly freeze again unless you fix the root symptom. Get in touch with an HVAC specialist to address issues with your air conditioner, which may include:
- Refrigerant leak: AC units recycle refrigerant, so it shouldn’t run out. Low refrigerant means there’s a leak somewhere. Only a professional can locate the leak, repair it, and recharge the air conditioner to the appropriate level.
- Filthy evaporator coil: If dust accumulates on the coil, air can’t flow over it, and it’s likely to freeze.
- Nonfunctional blower: A bad motor or unbalanced fan may prevent airflow over the evaporator coil.
