Does the air emitting from your supply registers unexpectedly appear hot? Inspect 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 might be ice on the evaporator coil. The AC coil inside the equipment could have frosted over. You’ll need to melt 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 help with air conditioning repair in Ocala backed by a 100% satisfaction guarantee.*
Step 1: Switch the Air Conditioning Off and the Blower On
To begin—set the thermostat from “cool” to “off.” This stops chilled refrigerant from flowing to the outdoor compressor, which could hurt it and lead to an expensive repair.
After that, move the fan from “auto” to “on.” This creates heated 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 start 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, check the condensate pan underneath the AC unit. If the drain line is blocked, it can overflow as the ice melts, potentially resulting in water damage.
Step 2: Pinpoint the Issue
Poor airflow is a prime reason for an AC to become frozen. Here’s how to figure out the problem:
- Check the filter. Insufficient airflow through a dirty filter could be the culprit. Inspect and put in a new filter once a month or immediately when you notice dust accumulation.
- Open any sealed supply vents. Your house’s supply registers should be open always. Sealing vents limits airflow over the evaporator coil, which could cause it to freeze.
- Check for blocked return vents. These often 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 conditioner could also not have enough refrigerant. Depending on its age, it may use Freon® or Puron®. Low refrigerant necessitates skilled assistance from a certified HVAC tech. H2: Step 3: Get in Touch with an HVAC Pro at Service Experts Heating & Air Conditioning
If insufficient airflow doesn’t appear to be the trouble, then something else is making your AC freeze. If this is the case, simply defrosting it won’t take care of the trouble. The evaporator coil will probably keep freezing 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, mend it, and recharge the system to the appropriate concentration.
- 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 stop airflow over the evaporator coil.
