Does the air emitting from your supply registers abruptly appear hot? Inspect 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 seeping onto the floor, there could be frost on the evaporator coil. The AC coil inside the system might have frozen over. You’ll need to defrost it before it can cool your residence again.
Here’s the things you should do. If you can’t get the coil frost-free, 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 begin—switch the thermostat from “cool” to “off.” This prevents chilled refrigerant from going to the outdoor compressor, which could hurt 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 the majority of the day for the ice to thaw, depending on the level of the buildup. While you’re waiting, watch 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
Low airflow is a primary explanation for an AC to frost over. Here’s how to figure out the problem:
- Exmaine the filter. Inadequate airflow through a dusty filter could be to blame. Look at and change the filter monthly or once you notice dust accumulation.
- Open any closed supply vents. Your residence’s supply registers should remain open all the time. Shutting vents limits airflow over the evaporator coil, which could lead it to freeze.
- Check for obstructed return vents. These typically don’t use adjustable louvers, but furniture, rugs or curtains can still block them.
- Not enough refrigerant: While airflow restrictions are the most typical culprit, your air conditioning may also have insufficient refrigerant. Depending on how old it is, it may rely on Freon® or Puron®. Insufficient refrigerant requires pro help from a certified HVAC specialist. 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, merely thawing it out won’t take care of the problem. The evaporator coil will possibly keep freezing unless you take care of the main problem. Call an HVAC tech to look for troubles with your air conditioner, which could include:
- Refrigerant leak: AC units keep using refrigerant, so it shouldn’t get used up. Not enough refrigerant indicates a leak somewhere. Only a professional can locate the leak, mend it, and recharge the air conditioning to the appropriate level.
- Grimy evaporator coil: If dust collects on the coil, air can’t flow over it, and it’s liable to freeze.
- Malfunctioning blower: A defective motor or unbalanced fan may prevent airflow over the evaporator coil.
