Does the air emitting from your supply registers unexpectedly feel not cold enough? Look at the indoor part of your air conditioner. This component is located inside your furnace or air handler, if you use a heat pump. If there’s water leaking onto the floor, there might be ice on the evaporator coil. The AC coil within the unit might have frozen over. You’ll need to defrost it before it can cool your residence again.
Here’s the steps you should take. If you can’t get the coil defrosted, Freschi Service Experts is here to support you with air conditioning repair in Concord that includes a 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 prevents cold refrigerant from flowing to the outdoor compressor, which could harm it and result in an expensive repair.
Next, switch the fan from “auto” to “on.” This produces heated airflow over the frozen coils to help them melt faster. Make sure to set the cooling mode to “off” so the air conditioner doesn’t begin a cooling cycle.
It might take not more than an hour or the better part of a day for the ice to melt, depending on the level of the accumulation. While you’re waiting, keep an eye on the condensate pan underneath the AC unit. If the drain line is clogged, it could spill over as the ice melts, potentially creating water damage.
Step 2: Diagnose the Trouble
Not enough airflow is a primary reason for an AC to freeze up. Here’s how to figure out the issue:
- Inspect the filter. Poor airflow through a dirty filter could be the problem. Check and put in a new filter monthly or immediately when you observe dust buildup.
- Open any shut supply vents. Your home’s supply registers should be open always. Shutting vents reduces airflow over the evaporator coil, which might lead it to freeze.
- Look for obstructed return vents. These typically don’t come with moveable louvers, but furniture, rugs or curtains can still cover them.
- Insufficient refrigerant: While airflow restrictions are the most typical culprit, your air conditioning might also not have enough refrigerant. Depending on its age, it may have Freon® or Puron®. Insufficient refrigerant calls for professional support from a certified HVAC technician. H2: Step 3: Call an HVAC Expert at Freschi Service Experts
If inadequate airflow doesn’t appear to be the issue, then another problem is making your AC freeze up. If this is what’s occurring, merely defrosting it won’t fix the issue. The evaporator coil will possibly keep freezing unless you take care of the underlying symptom. Get in touch with an HVAC pro to address issues with your air conditioner, which could include:
- Refrigerant leak: AC units keep using refrigerant, so it shouldn’t get used up. Insufficient refrigerant is a sign of a leak somewhere. Only a technician can find the leak, mend it, and recharge the system to the proper concentration.
- Grimy evaporator coil: If dirt builds up on the coil, air can’t get to it, and it’s apt to freeze.
- Nonfunctional blower: A faulty motor or unbalanced fan might stop airflow over the evaporator coil.
