Does the air flowing from your supply registers suddenly seem warm? Inspect the indoor portion of your air conditioner. This component is housed in your furnace or air handler, if you have a heat pump. If there’s water dripping onto the floor, there could be frost on the evaporator coil. The AC coil inside the system may have frozen. You’ll need to defrost it before it can cool your house again.
Here’s what to do. If you can’t get the coil back to normal, Roland J. Down Service Experts is here to support you with air conditioning repair in Albany upheld by a 100% satisfaction guarantee.*
Step 1: Set the Air Conditioning to Off and the Blower On
To get started—switch the thermostat from “cool” to “off.” This prevents chilly refrigerant from moving to the outdoor compressor, which could hurt it and lead to a pricey repair.
After that, move the fan from “auto” to “on.” This produces warm airflow over the frosty 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 under an hour or the better part of a day for the ice to defrost, depending on the amount of the accumulation. While you’re waiting, check the condensate pan underneath the AC unit. If the drain line is clogged, it can create a mess as the ice melts, potentially resulting in water damage.
Step 2: Troubleshoot the Issue
Poor airflow is a prime reason for an AC to freeze up. Here’s how to figure out the issue:
- Inspect the filter. Inadequate airflow through a dusty filter could be to blame. Inspect and replace the filter each month or immediately when you see dust buildup.
- Open any closed supply vents. Your residence’s supply registers should remain open constantly. Sealing vents decreases airflow over the evaporator coil, which might result in it freezing.
- Look for obstructed return vents. These typically don’t use moveable louvers, but furniture, rugs or curtains can still cover them.
- Insufficient refrigerant: While airflow restrictions are the most typical culprit, your air conditioner could also be low on refrigerant. Depending on when it was replaced, it may use Freon® or Puron®. Low refrigerant calls for professional support from a certified HVAC specialist.

If inadequate airflow doesn’t seem to be the trouble, then another issue is leading your AC frost over. If this is the case, just letting it melt won’t take care of the trouble. The evaporator coil will possibly continually freeze unless you take care of the underlying cause. Get in touch with an HVAC technician to check for troubles with your air conditioner, which can include:
- Refrigerant leak: AC units continuously use refrigerant, so it shouldn’t run out. Low refrigerant is a sign of a leak somewhere. Only a specialist can pinpoint the leak, repair it, and recharge the air conditioner to the proper concentration.
- Dirty evaporator coil: If dirt builds up on the coil, air can’t get to it, and it’s likely to freeze.
- Nonfunctional blower: A bad motor or unbalanced fan may stop airflow over the evaporator coil.
