Does the air flowing from your supply registers unexpectedly appear warm? Inspect the indoor component of your air conditioner. This part is situated inside your furnace or air handler, if you have a heat pump. If there’s water seeping onto the floor, there may be crystals on the evaporator coil. The AC coil within the equipment might have frosted over. You’ll need to thaw it before it can cool your house again.
Here’s what to do. If you can’t get the coil frost-free, Broad Ripple Service Experts is here to assist you with air conditioning repair in Indianapolis that includes a a 100% satisfaction guarantee.*
Step 1: Turn the Air Conditioning 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 hurt it and cause a pricey repair.
After that, adjust the fan from “auto” to “on.” This creates hot airflow over the crystallized coils to help them thaw faster. Double check to set the cooling mode to “off” so the air conditioner doesn’t start a cooling cycle.
It could take under 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 below the AC unit. If the drain line is blocked, it may create a mess as the ice melts, likely resulting in water damage.
Step 2: Diagnose the Issue
Not enough airflow is a prime reason for an AC to freeze up. Here’s how to figure out the problem:
- Check the filter. Poor airflow through a dusty filter could be the issue. Inspect and change the filter once a month or once you notice dust accumulation.
- Open any sealed supply vents. Your residence’s supply registers should remain open all the time. Shutting vents decreases airflow over the evaporator coil, which could cause it to freeze.
- Look for covered return vents. These typically don’t use moveable louvers, but furniture, rugs or curtains can still cover them.
- Insufficient refrigerant: While airflow restrictions are the most typical cause, your system could also be low on refrigerant. Depending on its age, it may use Freon®. Low refrigerant calls for pro help from a certified HVAC technician. H2: Step 3: Contact an HVAC Technician at Broad Ripple Service Experts
If poor airflow doesn’t feel like the trouble, then another issue is causing your AC freeze. If this is what’s happening, simply defrosting it won’t take care of the problem. The evaporator coil is likely to continually freeze unless you fix the root issue. Get in touch with an HVAC specialist to look for issues with your air conditioner, which can include:
- Refrigerant leak: AC units keep using refrigerant, so it shouldn’t run out. Not enough refrigerant is a sign of a leak somewhere. Only a pro can locate the leak, fix it, and recharge the air conditioner to the appropriate concentration.
- Grimy evaporator coil: If dirt collects on the coil, air can’t flow over it, and it’s likely to freeze.
- Nonfunctional blower: A bad motor or unbalanced fan may halt airflow over the evaporator coil.
