Does the air flowing from your supply registers abruptly seem warm? Look at the indoor part of your air conditioner. This piece is situated within your furnace or air handler, if you rely on a heat pump. If there’s water dripping onto the floor, there could be frost on the evaporator coil. The AC coil inside the system could have frosted over. You’ll need to melt it before it can cool your residence again.
Here’s the things you should do. If you can’t get the coil defrosted, Rob's Albertan Service Experts is here to help with air conditioning repair in Edmonton that includes a a 100% satisfaction guarantee.*
Step 1: Switch the Air Conditioning Off and the Blower On
To begin—switch the thermostat from “cool” to “off.” This prevents chilly refrigerant from flowing to the outdoor compressor, which could harm it and lead to a pricey repair.
After that, switch the fan from “auto” to “on.” This produces warm airflow over the frosty coils to force them to thaw faster. Double check to set the cooling mode to “off” so the air conditioner doesn’t start a cooling cycle.
It may take not more than an hour or the majority of the day for the ice to defrost, depending on the level of the accumulation. While you’re waiting, watch the condensate pan underneath the AC unit. If the drain line is clogged, it may cause a mess as the ice melts, likely resulting in water damage.
Step 2: Troubleshoot the Problem
Low airflow is a chief cause for an AC to freeze up. Here’s how to figure out the problem:
- Check the filter. Low airflow through a dirty filter could be to blame. Check and change the filter once a month or once you observe a layer of dust.
- Open any closed supply vents. Your residence’s supply registers should remain open always. Closing vents decreases airflow over the evaporator coil, which might lead it to freeze.
- Be on the lookout for covered return vents. These usually don’t come with shiftable louvers, but furniture, rugs or curtains can still obstruct them.
- Not enough refrigerant: While airflow restrictions are the most common cause, your system might also have insufficient refrigerant. Depending on when it was installed, it may rely on Freon®. Not enough refrigerant necessitates professional support from a certified HVAC technician. H2: Step 3: Get in Touch with an HVAC Specialist at Rob's Albertan Service Experts
If low airflow doesn’t seem to be the problem, then another issue is making your AC freeze up. If this is what’s going on, simply defrosting it won’t take care of the issue. The evaporator coil will probably freeze again unless you take care of the underlying cause. Contact an HVAC pro to address issues with your air conditioner, which could include:
- Refrigerant leak: AC units keep using refrigerant, so it shouldn’t run low. Low refrigerant signals a leak somewhere. Only a pro can find the leak, fix it, and recharge the air conditioner to the proper amount.
- Dirty evaporator coil: If dust collects on the coil, air can’t get to it, and it’s apt to freeze.
- Broken blower: A faulty motor or unbalanced fan can halt airflow over the evaporator coil.
