Does the air coming from your supply registers suddenly seem not cold enough? Look at the indoor portion of your air conditioner. This component is situated inside your furnace or air handler, if you use a heat pump. If there’s water leaking onto the floor, there could be frost on the evaporator coil. The AC coil in 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 frost-free, Robinson Service Experts is here to support you with air conditioning repair in Waukegan that includes a a 100% satisfaction guarantee.*
Step 1: Set the Air Conditioning to Off and the Blower On
To get started—move the thermostat from “cool” to “off.” This halts chilled refrigerant from moving to the outdoor compressor, which could hurt it and lead to a pricey repair.
Next, switch the fan from “auto” to “on.” This makes heated airflow over the frosty coils to make them defrost faster. Remember to set the cooling mode to “off” so the air conditioner doesn’t begin a cooling cycle.
It may take not more than an hour or the majority of the day for the ice to defrost, depending on the amount of the ice. While you’re waiting, check the condensate pan under the AC unit. If the drain line is clogged, it can cause a mess as the ice melts, possibly causing water damage.
Step 2: Troubleshoot the Situation
Bad airflow is a main cause for an AC to freeze up. Here’s how to figure out the issue:
- Look at the filter. Inadequate airflow through a clogged filter could be the problem. Check and put in a new filter once a month or once you notice dust buildup.
- Open any closed supply vents. Your residence’s supply registers should stay open all the time. Closing vents decreases airflow over the evaporator coil, which could result in it freezing.
- Look for covered return vents. These typically don’t have shiftable louvers, but furniture, rugs or curtains can still obstruct them.
- Insufficient refrigerant: While airflow restrictions are the most frequent culprit, your air conditioner might also have insufficient refrigerant. Depending on its age, it may have Freon®. Low refrigerant requires skilled attention from a certified HVAC specialist. H2: Step 3: Call an HVAC Professional at Robinson Service Experts
If low airflow doesn’t feel like the issue, then another issue is leading your AC freeze. If this is the case, simply thawing it out won’t repair the issue. The evaporator coil will possibly continually freeze unless you take care of the root problem. Call an HVAC pro to check for issues with your air conditioner, which might include:
- Refrigerant leak: AC units recycle refrigerant, so it shouldn’t get used up. Low refrigerant signals a leak somewhere. Only a tech can pinpoint the leak, fix it, and recharge the air conditioner to the correct concentration.
- Grimy evaporator coil: If dirt collects on the coil, air can’t get to it, and it’s liable to freeze.
- Nonfunctional blower: A bad motor or unbalanced fan may stop airflow over the evaporator coil.
