Does the air coming from your supply registers abruptly feel hot? Check the indoor component of your air conditioner. This part is located in your furnace or air handler, if you use a heat pump. If there’s water dripping onto the floor, there may be crystals on the evaporator coil. The AC coil inside the system could have frosted over. You’ll need to thaw it before it can cool your residence again.
Here’s the steps you should take. If you can’t get the coil back to normal, Peitz Service Experts is here to help with air conditioning repair in Pierre upheld by a 100% satisfaction guarantee.*
Step 1: Turn the Air Conditioning Off and the Blower On
To get started—move the thermostat from “cool” to “off.” This halts cold refrigerant from flowing to the outdoor compressor, which could harm it and cause a costly repair.
Then, adjust the fan from “auto” to “on.” This produces hot airflow over the frozen coils to help them defrost faster. Double check to set the cooling mode to “off” so the air conditioner doesn’t trigger a cooling cycle.
It can take not more than an hour or the majority of the day for the ice to thaw, depending on the amount of the accumulation. While you’re waiting, watch the condensate pan under the AC unit. If the drain line is obstructed, it may overflow as the ice melts, possibly creating water damage.
Step 2: Pinpoint the Problem
Poor airflow is a prime reason for an AC to become frozen. Here’s how to troubleshoot the issue:
- Look at the filter. Low airflow through a filthy filter could be the problem. Inspect and change the filter once a month or immediately when you notice a layer of dust.
- Open any sealed supply vents. Your home’s supply registers should stay open constantly. Shutting vents reduces airflow over the evaporator coil, which can result in it freezing.
- Check for obstructed return vents. These typically don’t come with adjustable louvers, but furniture, rugs or curtains can still cover them.
- Insufficient refrigerant: While airflow restrictions are the most common suspect, your system may also be low on refrigerant. Depending on its age, it may have Freon®. Not enough refrigerant calls for pro assistance from a certified HVAC specialist. H2: Step 3: Get in Touch with an HVAC Expert at Peitz Service Experts
If insufficient airflow doesn’t feel like the problem, then another problem is leading your AC freeze up. If this is what’s happening, merely letting it melt won’t repair the problem. The evaporator coil will possibly continually freeze unless you fix the underlying problem. Get in touch with an HVAC tech to look for issues with your air conditioner, which may include:
- Refrigerant leak: AC units recycle refrigerant, so it shouldn’t get used up. Insufficient refrigerant is a sign of a leak somewhere. Only a tech can locate the leak, mend it, and recharge the air conditioner to the appropriate amount.
- Grimy evaporator coil: If dust collects on the coil, air can’t reach it, and it’s likely to freeze.
- Malfunctioning blower: A broken motor or unbalanced fan could stop airflow over the evaporator coil.
