Repair Your Frozen Air Conditioner with These 3 Fast Tips

Does the air coming from your supply registers unexpectedly seem not cold enough? Check the indoor part of your air conditioner. This component is housed in your furnace or air handler, if you use a heat pump. If there’s water seeping onto the floor, there may be frost on the evaporator coil. The AC coil within the equipment may have frozen. 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 back to normal, Service Experts Heating & Air Conditioning is here to assist you with air conditioning repair in Gainesville that includes a a 100% satisfaction guarantee.*

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

First things first—switch the thermostat from “cool” to “off.” This halts chilly refrigerant from flowing to the outdoor compressor, which could damage it and cause a pricey repair.

After that, switch the fan from “auto” to “on.” This makes heated airflow over the crystallized coils to force them to thaw faster. Double check to set the cooling mode to “off” so the air conditioner doesn’t start a cooling cycle.

It may take not more than an hour or the majority of the day for the ice to thaw, depending on the degree of the ice. While you’re waiting, check the condensate pan below the AC unit. If the drain line is obstructed, it may cause a mess as the ice melts, potentially creating water damage.

Step 2: Troubleshoot the Problem

Poor airflow is a prime cause for an AC to freeze up. Here’s how to get to the bottom of the situation:

  • Look at the filter. Low airflow through a dirty filter could be the issue. Check and change the filter once a month or once you see dust buildup.
  • Open any sealed supply vents. Your house’s supply registers should stay open all the time. Sealing vents limits airflow over the evaporator coil, which could cause it to freeze.
  • Look for covered return vents. These often don’t use adjustable louvers, but furniture, rugs or curtains can still cover them.
  • Insufficient refrigerant: While airflow restrictions are the most frequent cause, your system could also not have enough refrigerant. Depending on when it was installed, it may use Freon®. Low refrigerant requires professional assistance from a certified HVAC specialist. H2: Step 3: Call an HVAC Expert at Service Experts Heating & Air Conditioning

If insufficient airflow doesn’t feel like the problem, then another issue is making your AC frost over. If this is what’s occurring, just thawing it out won’t fix the trouble. The evaporator coil will probably freeze again unless you repair the main problem. Call an HVAC professional to check for issues with your air conditioner, which could include:

  • Refrigerant leak: AC units recycle refrigerant, so it shouldn’t get used up. Low refrigerant indicates a leak somewhere. Only a technician can find the leak, fix it, and recharge the system to the proper concentration.
  • Dirty evaporator coil: If dust collects on the coil, air can’t flow over it, and it’s likely to freeze.
  • Nonfunctional blower: A defective motor or unbalanced fan might halt airflow over the evaporator coil.
