Quick Steps to Repair a Frozen Air Conditioner

Does the air emitting from your supply registers suddenly seem warm? Inspect the indoor component of your air conditioner. This piece is situated in your furnace or air handler, if you rely on a heat pump. If there’s water seeping onto the floor, there might be ice on the evaporator coil. The AC coil in the system may have frosted over. You’ll need to melt it before it can cool your home again.

Here’s the steps you should take. If you can’t get the coil defrosted, Winnipeg Supply Service Experts is here to assist you with air conditioning repair in Winnipeg that includes a a 100% satisfaction guarantee.*

Step 1: Turn the Air Conditioning Off and the Blower On

To begin—move the thermostat from “cool” to “off.” This halts chilled refrigerant from moving to the outdoor compressor, which could damage it and result in a costly repair.

Next, switch the fan from “auto” to “on.” This makes heated airflow over the frozen coils to force them to melt faster. Double check to set the cooling mode to “off” so the air conditioner doesn’t begin a cooling cycle.

It can take under an hour or most of the day for the ice to melt, depending on the level of the ice. While you’re waiting, watch the condensate pan under the AC unit. If the drain line is blocked, it can spill over as the ice melts, likely resulting in water damage.

Step 2: Pinpoint the Problem

Bad airflow is a main cause for an AC to frost over. Here’s how to figure out the problem:

    • Check the filter. Insufficient airflow through a clogged filter could be the problem. Inspect and change the filter each month or once you notice a layer of dust.
    • Open any shut supply vents. Your residence’s supply registers should remain open all the time. Sealing vents reduces airflow over the evaporator coil, which might lead it to freeze.
    • Check for covered return vents. These typically don’t come with adjustable louvers, but furniture, rugs or curtains can still block them.
    • Not enough refrigerant: While airflow restrictions are the most common culprit, your air conditioner could also have insufficient refrigerant. Depending on its age, it may have Freon®. Not enough refrigerant requires professional help from a certified HVAC specialist. H2: Step 3: Call an HVAC Pro at Winnipeg Supply Service Experts

If low airflow doesn’t feel like the problem, then another problem is making your AC frost over. If this is what’s happening, simply thawing it out won’t fix the issue. The evaporator coil will probably freeze again unless you take care of the main cause. Get in touch with an HVAC professional to look for problems with your air conditioner, which may include:

    • Refrigerant leak: AC units recycle refrigerant, so it shouldn’t run low. Low refrigerant is a sign of a leak somewhere. Only a tech can find the leak, mend it, and recharge the air conditioner to the proper level.
    • Filthy evaporator coil: If dust collects on the coil, air can’t flow over it, and it’s likely to freeze.
    • Nonfunctional blower: A bad motor or unbalanced fan could stop airflow over the evaporator coil.
