Does the air coming from your supply registers suddenly seem not cold enough? Look at the indoor component of your air conditioner. This piece is located in your furnace or air handler, if you use a heat pump. If there’s water leaking onto the floor, there could be frost on the evaporator coil. The AC coil inside the unit could have frozen over. You’ll need to melt it before it can cool your home again.
Here’s what to do. If you can’t get the coil frost-free, Service Experts Heating & Air Conditioning is here to help with air conditioning repair in Cleveland upheld by a 100% satisfaction guarantee.*
Step 1: Turn the Air Conditioning Off and the Blower On
To get started—switch the thermostat from “cool” to “off.” This prevents chilly refrigerant from moving to the outdoor compressor, which could damage it and result in an expensive repair.
Then, switch the fan from “auto” to “on.” This produces warm airflow over the frosty coils to make them melt faster. Remember to set the cooling mode to “off” so the air conditioner doesn’t trigger a cooling cycle.
It can take under an hour or the better part of a day for the ice to melt, depending on the level of the accumulation. While you’re waiting, watch the condensate pan under the AC unit. If the drain line is obstructed, it can cause a mess as the ice melts, potentially creating water damage.
Step 2: Pinpoint the Issue
Poor airflow is a main explanation for an AC to freeze up. Here’s how to troubleshoot the issue:
- Look at the filter. Insufficient airflow through a clogged filter could be the issue. Inspect and put in a new filter once a month or once you notice a layer of dust.
- Open any shut supply vents. Your house’s supply registers should remain open always. Shutting vents limits airflow over the evaporator coil, which might cause it to freeze.
- Check for blocked return vents. These typically don’t come with adjustable louvers, but furniture, rugs or curtains can still obstruct them.
- Insufficient refrigerant: While airflow restrictions are the most typical culprit, your air conditioning could also not have enough refrigerant. Depending on its age, it may use Freon®. Low refrigerant calls for pro help from a certified HVAC specialist. H2: Step 3: Call an HVAC Specialist at Service Experts Heating & Air Conditioning
If low airflow doesn’t seem to be the trouble, then another issue is leading your AC freeze. If this is the case, simply letting it melt won’t take care of the trouble. The evaporator coil will probably keep freezing unless you fix the root problem. Get in touch with an HVAC professional to check for issues with your air conditioner, which might include:
- Refrigerant leak: AC units continuously use refrigerant, so it shouldn’t run low. Not enough refrigerant means there’s a leak somewhere. Only a professional can find the leak, mend it, and recharge the air conditioner to the correct concentration.
- Grimy evaporator coil: If dirt builds up on the coil, air can’t flow over it, and it’s likely to freeze.
- Broken blower: A defective motor or unbalanced fan can prevent airflow over the evaporator coil.
