Does the air emitting from your supply registers unexpectedly feel warm? Look at the indoor part of your air conditioner. This part is situated within your furnace or air handler, if you have a heat pump. If there’s water dripping onto the floor, there may be frost on the evaporator coil. The AC coil in the equipment may have frosted over. 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 frost-free, Service Experts Heating, Air Conditioning & Plumbing is here to help with air conditioning repair in the U.S. upheld by a 100% satisfaction guarantee.*
To begin—set the thermostat from “cool” to “off.” This prevents chilly refrigerant from moving to the outdoor compressor, which could hurt it and cause an expensive repair.
After that, adjust the fan from “auto” to “on.” This makes heated airflow over the crystallized coils to make them 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 extent of the buildup. While you’re waiting, keep an eye on the condensate pan below the AC unit. If the drain line is clogged, it may cause a mess as the ice melts, likely causing water damage.
Bad airflow is a leading reason for an AC to frost over. Here’s how to troubleshoot the problem:
If inadequate airflow doesn’t appear to be the trouble, then another issue is causing your AC freeze. If this is what’s occurring, simply letting it melt won’t take care of the issue.
