Does the air emitting from your supply registers unexpectedly appear not cold enough? Check the indoor component of your air conditioner. This piece is housed within your furnace or air handler, if you rely on a heat pump. If there’s water leaking onto the floor, there might be ice on the evaporator coil. The AC coil in the equipment could 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, Comfort Masters Service Experts is here to assist you with air conditioning repair in Wheeling that includes a a 100% satisfaction guarantee.*
Step 1: Switch the Air Conditioning Off and the Blower On
First things first—move the thermostat from “cool” to “off.” This stops chilled refrigerant from flowing to the outdoor compressor, which could damage it and cause a pricey repair.
After that, move the fan from “auto” to “on.” This produces warm airflow over the crystallized coils to help them defrost faster. Remember to set the cooling mode to “off” so the air conditioner doesn’t trigger 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 buildup. While you’re waiting, keep an eye on the condensate pan under the AC unit. If the drain line is blocked, it may cause a mess as the ice melts, possibly resulting in water damage.
Step 2: Troubleshoot the Issue
Low airflow is a prime cause for an AC to frost over. Here’s how to get to the bottom of the problem:
- Exmaine the filter. Low airflow through a filthy filter could be the issue. Inspect and put in a new filter each month or immediately when you notice dust accumulation.
- Open any shut supply vents. Your residence’s supply registers should remain open all the time. Shutting vents reduces airflow over the evaporator coil, which can lead it to freeze.
- Be on the lookout for obstructed return vents. These usually don’t use shiftable louvers, but furniture, rugs or curtains can still obstruct them.
- Not enough refrigerant: While airflow restrictions are the most typical cause, your air conditioner may also be low on refrigerant. Depending on when it was replaced, it may have Freon® or Puron®. Low refrigerant necessitates pro help from a certified HVAC tech. H2: Step 3: Contact an HVAC Specialist at Comfort Masters Service Experts
If poor airflow doesn’t seem to be the issue, then another problem is leading your AC freeze. If this is the case, just letting it melt won’t repair the problem. The evaporator coil will possibly continually freeze unless you take care of the main issue. Get in touch with an HVAC technician to address problems with your air conditioner, which might include:
- Refrigerant leak: AC units keep using refrigerant, so it shouldn’t run low. Insufficient refrigerant indicates a leak somewhere. Only a technician can find the leak, fix it, and recharge the system to the appropriate concentration.
- Dirty evaporator coil: If grime accumulates on the coil, air can’t get to it, and it’s liable to freeze.
- Malfunctioning blower: A bad motor or unbalanced fan might stop airflow over the evaporator coil.
