Does the air flowing from your supply registers abruptly seem hot? Inspect the indoor component of your air conditioner. This part is located in your furnace or air handler, if you rely on a heat pump. If there’s water dripping onto the floor, there could be ice on the evaporator coil. The AC coil inside the system may have frosted over. You’ll need to thaw it before it can cool your home again.
Here’s the things you should do. If you can’t get the coil frost-free, Service Experts Heating & Air Conditioning is here to help with air conditioning repair in Kingston upheld by a 100% satisfaction guarantee.*
Step 1: Set the Air Conditioning to Off and the Blower On
First things first—switch the thermostat from “cool” to “off.” This halts chilled refrigerant from moving to the outdoor compressor, which could damage it and result in a costly repair.
Then, move the fan from “auto” to “on.” This creates warm airflow over the frosty coils to make them thaw faster. Double check 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 the majority of the day for the ice to melt, depending on the level of the accumulation. While you’re waiting, keep an eye on the condensate pan underneath the AC unit. If the drain line is clogged, it might cause a mess as the ice melts, potentially causing water damage.
Step 2: Pinpoint the Trouble
Bad airflow is a main reason for an AC to become frozen. Here’s how to figure out the situation:
- Inspect the filter. Insufficient airflow through a filthy filter could be the problem. Inspect and change the filter once a month or immediately when you see dust accumulation.
- Open any closed supply vents. Your home’s supply registers should remain open constantly. Sealing vents decreases airflow over the evaporator coil, which could cause it to freeze.
- Check for blocked return vents. These typically don’t use shiftable louvers, but furniture, rugs or curtains can still cover them.
- Not enough refrigerant: While airflow restrictions are the most frequent culprit, your air conditioning might also be low on refrigerant. Depending on how old it is, it may have Freon® or Puron®. Insufficient refrigerant calls for skilled support from a certified HVAC technician. H2: Step 3: Get in Touch with an HVAC Expert at Service Experts Heating & Air Conditioning
If inadequate airflow doesn’t seem to be the issue, then something else is causing your AC freeze. If this is what’s occurring, just letting it melt won’t take care of the issue. The evaporator coil will probably continually freeze unless you fix the underlying issue. Call an HVAC professional to check for troubles with your air conditioner, which can include:
- Refrigerant leak: AC units keep using refrigerant, so it shouldn’t run out. Insufficient refrigerant signals a leak somewhere. Only a tech can pinpoint the leak, mend it, and recharge the air conditioning to the appropriate concentration.
- Dirty evaporator coil: If dust collects on the coil, air can’t flow over it, and it’s liable to freeze.
- Broken blower: A broken motor or unbalanced fan can halt airflow over the evaporator coil.
