Does the air flowing from your supply registers abruptly seem hot? Look at the indoor portion of your air conditioner. This piece is located within your furnace or air handler, if you use a heat pump. If there’s water leaking onto the floor, there might be crystals on the evaporator coil. The AC coil within the equipment might have frosted over. You’ll need to melt it before it can cool your home 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. backed by a 100% satisfaction guarantee.*
To begin—switch the thermostat from “cool” to “off.” This prevents chilly refrigerant from going to the outdoor compressor, which could hurt it and result in an expensive repair.
Next, switch the fan from “auto” to “on.” This creates hot airflow over the frozen coils to help them thaw faster. Make sure to set the cooling mode to “off” so the air conditioner doesn’t begin a cooling cycle.
It can take less than an hour or the better part of a day for the ice to thaw, depending on the amount of the accumulation. While you’re waiting, watch 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.
Bad airflow is a primary reason for an AC to become frozen. Here’s how to troubleshoot the problem:
If low airflow doesn’t appear to be the issue, then another problem is causing your AC freeze. If this is what’s occurring, merely thawing it out won’t fix the problem. The evaporator coil will possibly continually freeze unless you fix the underlying symptom. Call an HVAC specialist to look for troubles with your air conditioner, which could include:
