Does the air emitting from your supply registers unexpectedly appear hot? Look at the indoor part of your air conditioner. This piece is housed within your furnace or air handler, if you rely on a heat pump. If there’s water dripping onto the floor, there could be ice on the evaporator coil. The AC coil inside the equipment might have frosted over. You’ll need to melt it before it can cool your home again.
Here’s the things you should do. If you can’t get the coil back to normal, Service Experts Heating & Air Conditioning is here to help with air conditioning repair in Ocala backed by a 100% satisfaction guarantee.*
Step 1: Set the Air Conditioning to Off and the Blower On
To begin—set the thermostat from “cool” to “off.” This halts chilly refrigerant from flowing to the outdoor compressor, which could harm it and lead to a pricey repair.
After that, move the fan from “auto” to “on.” This creates hot airflow over the frosty coils to force them to melt faster. Make sure to set the cooling mode to “off” so the air conditioner doesn’t trigger a cooling cycle.
It might take under an hour or the majority of the day for the ice to melt, depending on the amount of the buildup. While you’re waiting, watch the condensate pan underneath the AC unit. If the drain line is blocked, it can overflow as the ice melts, potentially creating water damage.
Step 2: Pinpoint the Issue
Poor airflow is a prime reason for an AC to become frozen. Here’s how to get to the bottom of the problem:
- Look at the filter. Insufficient airflow through a dusty filter could be the culprit. Inspect and replace the filter once a month or immediately when you observe dust accumulation.
- Open any sealed supply vents. Your house’s supply registers should be open always. Shutting vents decreases airflow over the evaporator coil, which could cause it to freeze.
- Check for blocked return vents. These usually don’t have shiftable louvers, but furniture, rugs or curtains can still block them.
- Insufficient refrigerant: While airflow restrictions are the most common culprit, your air conditioning might also have insufficient refrigerant. Depending on when it was installed, it may use Freon® or Puron®. Low refrigerant necessitates pro support from a certified HVAC tech.

If low airflow doesn’t appear to be the trouble, then something else is making your AC freeze. If this is what’s happening, simply defrosting it won’t take care of the trouble. The evaporator coil will probably continually freeze unless you repair the underlying cause. Contact an HVAC tech to address problems with your air conditioner, which may include:
- Refrigerant leak: AC units continuously use refrigerant, so it shouldn’t get used up. Low refrigerant is a sign of a leak somewhere. Only a tech can find the leak, repair it, and recharge the system to the appropriate amount.
- Dirty evaporator coil: If dirt builds up on the coil, air can’t reach it, and it’s apt to freeze.
- Nonfunctional blower: A faulty motor or unbalanced fan might halt airflow over the evaporator coil.
