3 Fast Ways to Restore a Frozen Air Conditioner

Does the air emitting from your supply registers abruptly appear not cold enough? Look at the indoor portion of your air conditioner. This part is housed inside your furnace or air handler, if you have a heat pump. If there’s water leaking onto the floor, there could be crystals on the evaporator coil. The AC coil inside the system could have frosted over. You’ll need to defrost it before it can cool your house again.

Here’s the things you should do. If you can’t get the coil back to normal, D.A. Bennett Service Experts is here to assist you with air conditioning repair in Albany that includes a a 100% satisfaction guarantee.*

Step 1: Set the Air Conditioning to Off and the Blower On

To get started—switch the thermostat from “cool” to “off.” This prevents chilly refrigerant from going to the outdoor compressor, which could harm it and lead to a pricey repair.

Next, move the fan from “auto” to “on.” This produces warm airflow over the frozen coils to help them thaw faster. Remember to set the cooling mode to “off” so the air conditioner doesn’t begin a cooling cycle.

It can take less than an hour or most of the day for the ice to thaw, depending on the extent of the buildup. While you’re waiting, check the condensate pan under the AC unit. If the drain line is obstructed, it can spill over as the ice melts, possibly causing water damage.

Step 2: Pinpoint the Issue

Poor airflow is a main explanation for an AC to frost over. Here’s how to get to the bottom of the problem:

  • Exmaine the filter. Inadequate airflow through a dusty filter could be the culprit. Look at and change the filter monthly or immediately when you observe dust accumulation.
  • Open any closed supply vents. Your residence’s supply registers should remain open all the time. Sealing vents decreases airflow over the evaporator coil, which could lead it to freeze.
  • Check for covered return vents. These typically don’t come with adjustable louvers, but furniture, rugs or curtains can still block them.
  • Insufficient refrigerant: While airflow restrictions are the most frequent suspect, your air conditioning may also not have enough refrigerant. Depending on how old it is, it may rely on Freon®. Not enough refrigerant requires skilled help from a certified HVAC tech. H2: Step 3: Get in Touch with an HVAC Professional at D.A. Bennett Service Experts

If poor airflow doesn’t seem to be the problem, then something else is making your AC freeze. If this is what’s occurring, just thawing it out won’t repair the problem. The evaporator coil will possibly keep freezing unless you take care of the root problem. Call an HVAC tech to look for troubles with your air conditioner, which may include:

  • Refrigerant leak: AC units continuously use refrigerant, so it shouldn’t get used up. Not enough refrigerant signals a leak somewhere. Only a professional can locate the leak, repair it, and recharge the air conditioner to the correct level.
  • Filthy evaporator coil: If dirt accumulates on the coil, air can’t flow over it, and it’s liable to freeze.
  • Malfunctioning blower: A defective motor or unbalanced fan could prevent airflow over the evaporator coil.
