Fix Your Frozen Air Conditioner with These 3 Easy Tips

Does the air emitting from your supply registers abruptly feel hot? Look at the indoor component of your air conditioner. This part is located in your furnace or air handler, if you use a heat pump. If there’s water leaking onto the floor, there could be crystals on the evaporator coil. The AC coil inside the unit could 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, Service Experts Heating & Air Conditioning is here to support you with air conditioning repair in Livermore backed by a 100% satisfaction guarantee.*

Step 1: Turn the Air Conditioning Off and the Blower On

To get started—switch the thermostat from “cool” to “off.” This halts chilled refrigerant from going to the outdoor compressor, which could hurt it and result in a pricey repair.

Then, move the fan from “auto” to “on.” This makes heated airflow over the frozen coils to make them thaw faster. Remember to set the cooling mode to “off” so the air conditioner doesn’t start a cooling cycle.

It could take under an hour or most of the day for the ice to melt, depending on the extent of the ice. While you’re waiting, keep an eye on the condensate pan below the AC unit. If the drain line is blocked, it might create a mess as the ice melts, possibly causing water damage.

Step 2: Diagnose the Trouble

Not enough airflow is a main cause for an AC to become frozen. Here’s how to figure out the situation:

  • Exmaine the filter. Low airflow through a clogged filter could be to blame. Look at and put in a new filter once a month or as soon as you see dust accumulation.
  • Open any shut supply vents. Your home’s supply registers should remain open constantly. Sealing vents limits airflow over the evaporator coil, which might cause it to freeze.
  • Look for covered return vents. These typically don’t use shiftable louvers, but furniture, rugs or curtains can still block them.
  • Low refrigerant: While airflow restrictions are the most typical cause, your air conditioning might also be low on refrigerant. Depending on when it was replaced, it may have Freon®. Insufficient refrigerant necessitates skilled assistance from a certified HVAC tech. H2: Step 3: Get in Touch with an HVAC Expert at Service Experts Heating & Air Conditioning

If poor airflow doesn’t feel like the issue, then something else is causing your AC freeze. If this is what’s occurring, merely thawing it out won’t fix the issue. The evaporator coil will possibly continually freeze unless you fix the underlying problem. Get in touch with an HVAC technician to address troubles with your air conditioner, which may include:

  • Refrigerant leak: AC units keep using refrigerant, so it shouldn’t get used up. Low refrigerant is a sign of a leak somewhere. Only a tech can pinpoint the leak, mend it, and recharge the air conditioning to the proper amount.
  • Dirty evaporator coil: If grime accumulates on the coil, air can’t reach it, and it’s liable to freeze.
  • Malfunctioning blower: A bad motor or unbalanced fan might stop airflow over the evaporator coil.
