Does the air emitting from your supply registers unexpectedly feel hot? Inspect the indoor component of your air conditioner. This component is housed inside your furnace or air handler, if you rely on a heat pump. If there’s water dripping onto the floor, there may be frost on the evaporator coil. The AC coil within the equipment may have frozen over. You’ll need to melt it before it can cool your house again.
Here’s what to do. If you can’t get the coil frost-free, Bryant Heating & Cooling Service Experts is here to assist you with air conditioning repair in Windsor upheld by a 100% satisfaction guarantee.*
Step 1: Switch the Air Conditioning Off and the Blower On
To get started—move the thermostat from “cool” to “off.” This prevents chilly 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 creates warm airflow over the crystallized coils to force them to thaw faster. Remember to set the cooling mode to “off” so the air conditioner doesn’t start a cooling cycle.
It might take not more than an hour or the majority of the day for the ice to thaw, depending on the level of the ice. While you’re waiting, check the condensate pan underneath the AC unit. If the drain line is obstructed, it can cause a mess as the ice melts, potentially creating water damage.
Step 2: Diagnose the Situation
Bad airflow is a main cause for an AC to frost over. Here’s how to figure out the issue:
- Check the filter. Insufficient airflow through a dirty filter could be the problem. Inspect and put in a new filter each month or once you observe a layer of dust.
- Open any sealed supply vents. Your residence’s supply registers should remain open all the time. Closing vents reduces airflow over the evaporator coil, which may result in it freezing.
- Look for obstructed return vents. These typically don’t use adjustable louvers, but furniture, rugs or curtains can still obstruct them.
- Low refrigerant: While airflow restrictions are the most frequent culprit, your air conditioner might also not have enough refrigerant. Depending on how old it is, it may rely on Freon® or Puron®. Insufficient refrigerant requires professional help from a certified HVAC specialist. H2: Step 3: Contact an HVAC Technician at Bryant Heating & Cooling Service Experts
If inadequate airflow doesn’t feel like the problem, then another issue is leading your AC freeze. If this is the case, just defrosting it won’t repair the problem. The evaporator coil is likely to freeze again unless you take care of the underlying symptom. Call an HVAC tech to look for issues with your air conditioner, which could include:
- Refrigerant leak: AC units continuously use refrigerant, so it shouldn’t get used up. Not enough refrigerant signals a leak somewhere. Only a tech can locate the leak, repair it, and recharge the air conditioner to the proper amount.
- Dirty evaporator coil: If grime builds up on the coil, air can’t get to it, and it’s apt to freeze.
- Malfunctioning blower: A defective motor or unbalanced fan may stop airflow over the evaporator coil.
