Does the air flowing from your supply registers unexpectedly appear hot? Check 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 leaking onto the floor, there might be ice on the evaporator coil. The AC coil in the equipment might have frosted over. You’ll need to defrost it before it can cool your home again.
Here’s the steps you should take. If you can’t get the coil back to normal, Service Experts Heating & Air Conditioning is here to assist you with air conditioning repair in Medina upheld by a 100% satisfaction guarantee.*
Step 1: Set the Air Conditioning to Off and the Blower On
First things first—set the thermostat from “cool” to “off.” This stops chilly refrigerant from going to the outdoor compressor, which could harm it and cause a pricey repair.
Then, switch the fan from “auto” to “on.” This produces warm airflow over the crystallized coils to force them to melt faster. Double check to set the cooling mode to “off” so the air conditioner doesn’t begin a cooling cycle.
It might take not more than an hour or the majority of the day for the ice to melt, depending on the extent of the ice. While you’re waiting, keep an eye on the condensate pan under the AC unit. If the drain line is obstructed, it could overflow as the ice melts, possibly creating water damage.
Step 2: Troubleshoot the Trouble
Bad airflow is a prime explanation for an AC to freeze up. Here’s how to get to the bottom of the situation:
- Exmaine the filter. Insufficient airflow through a clogged filter could be the culprit. Look at and change the filter monthly or once you see a layer of dust.
- Open any closed supply vents. Your residence’s supply registers should stay open always. Shutting vents decreases airflow over the evaporator coil, which can lead it to freeze.
- Check for covered return vents. These often don’t come with moveable louvers, but furniture, rugs or curtains can still block them.
- Insufficient refrigerant: While airflow restrictions are the most common suspect, your air conditioner might also not have enough refrigerant. Depending on when it was installed, it may have Freon®. Insufficient refrigerant requires professional attention from a certified HVAC tech.

If poor airflow doesn’t seem to be the problem, then something else is leading your AC frost over. If this is what’s going on, simply letting it melt won’t repair the problem. The evaporator coil will possibly keep freezing unless you take care of the main problem. Contact an HVAC specialist to check for problems with your air conditioner, which may include:
- Refrigerant leak: AC units continuously use refrigerant, so it shouldn’t run low. Insufficient refrigerant indicates a leak somewhere. Only a pro can locate the leak, repair it, and recharge the air conditioning to the correct level.
- Filthy evaporator coil: If dust accumulates on the coil, air can’t flow over it, and it’s likely to freeze.
- Malfunctioning blower: A broken motor or unbalanced fan might stop airflow over the evaporator coil.
