Does the air emitting from your supply registers abruptly appear hot? Check the indoor component of your air conditioner. This component is situated inside 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 within the system might have frosted over. You’ll need to defrost it before it can cool your home again.
Here’s the steps you should take. If you can’t get the coil defrosted, Niagara Home Services by Enercare is here to support you with air conditioning repair in Niagara Falls that includes a a 100% satisfaction guarantee.*
Step 1: Set the Air Conditioning to Off and the Blower On
To begin—set the thermostat from “cool” to “off.” This prevents cold refrigerant from flowing to the outdoor compressor, which could damage it and result in a costly repair.
After that, switch the fan from “auto” to “on.” This creates heated airflow over the frosty coils to force them to defrost faster. Double check to set the cooling mode to “off” so the air conditioner doesn’t begin a cooling cycle.
It may take not more than an hour or most of the day for the ice to defrost, depending on the extent of the accumulation. While you’re waiting, keep an eye on the condensate pan under the AC unit. If the drain line is clogged, it can create a mess as the ice melts, potentially resulting in water damage.
Step 2: Troubleshoot the Trouble
Low airflow is a chief reason for an AC to become frozen. Here’s how to troubleshoot the situation:
- Look at the filter. Low airflow through a clogged filter could be to blame. Check and change the filter once a month or once you see dust accumulation.
- Open any shut supply vents. Your residence’s supply registers should remain open always. Sealing vents reduces airflow over the evaporator coil, which could cause it to freeze.
- Be on the lookout for blocked return vents. These often don’t come with shiftable louvers, but furniture, rugs or curtains can still cover them.
- Not enough refrigerant: While airflow restrictions are the most typical suspect, your air conditioning might also be low on refrigerant. Depending on when it was installed, it may use Freon®. Not enough refrigerant calls for pro assistance from a certified HVAC specialist. H2: Step 3: Call an HVAC Tech at Niagara Home Services by Enercare
If low airflow doesn’t feel like the problem, then something else is making your AC freeze up. If this is what’s going on, simply letting it melt won’t repair the trouble. The evaporator coil will possibly continually freeze unless you fix the root cause. Get in touch with an HVAC tech to address issues with your air conditioner, which can include:
- Refrigerant leak: AC units continuously use refrigerant, so it shouldn’t run low. Low refrigerant indicates a leak somewhere. Only a specialist can pinpoint the leak, mend it, and recharge the air conditioning to the correct amount.
- Dirty evaporator coil: If dirt builds up on the coil, air can’t reach it, and it’s likely to freeze.
- Broken blower: A bad motor or unbalanced fan could halt airflow over the evaporator coil.
