Does the air emitting from your supply registers unexpectedly seem warm? Inspect the indoor component of your air conditioner. This part is located inside your furnace or air handler, if you rely on a heat pump. If there’s water leaking onto the floor, there may be crystals on the evaporator coil. The AC coil in the equipment could have frosted over. You’ll need to thaw it before it can cool your residence again.
Here’s what to do. If you can’t get the coil back to normal, Broad Ripple Service Experts is here to support you with air conditioning repair in Indianapolis that includes a a 100% satisfaction guarantee.*
Step 1: Turn the Air Conditioning Off and the Blower On
To begin—set the thermostat from “cool” to “off.” This stops chilly refrigerant from flowing to the outdoor compressor, which could harm it and cause an expensive repair.
After that, move the fan from “auto” to “on.” This creates hot airflow over the frosty coils to help them thaw faster. Make sure to set the cooling mode to “off” so the air conditioner doesn’t start a cooling cycle.
It may take under an hour or the better part of a day for the ice to melt, depending on the extent of the ice. While you’re waiting, keep an eye on the condensate pan below the AC unit. If the drain line is obstructed, it could overflow as the ice melts, likely resulting in water damage.
Step 2: Pinpoint the Issue
Not enough airflow is a prime cause for an AC to freeze up. Here’s how to get to the bottom of the problem:
- Look at the filter. Poor airflow through a dirty filter could be the issue. Look at and change the filter once a month or once you notice dust buildup.
- Open any shut supply vents. Your residence’s supply registers should remain open all the time. Sealing vents decreases airflow over the evaporator coil, which could cause it to freeze.
- Look for obstructed return vents. These typically don’t come with shiftable louvers, but furniture, rugs or curtains can still cover them.
- Insufficient refrigerant: While airflow restrictions are the most typical cause, your system could also be low on refrigerant. Depending on when it was installed, it may use Freon® or Puron®. Low refrigerant calls for pro help from a certified HVAC technician. H2: Step 3: Contact an HVAC Technician at Broad Ripple Service Experts
If poor airflow doesn’t feel like the issue, then another issue is causing your AC freeze. If this is what’s happening, simply defrosting it won’t repair the problem. The evaporator coil is likely to keep freezing unless you fix the root issue. Get in touch with an HVAC specialist to address troubles with your air conditioner, which can include:
- Refrigerant leak: AC units continuously use refrigerant, so it shouldn’t run out. Insufficient refrigerant is a sign of a leak somewhere. Only a pro can pinpoint the leak, fix it, and recharge the air conditioning to the appropriate amount.
- Grimy evaporator coil: If dirt accumulates on the coil, air can’t get to it, and it’s apt to freeze.
- Nonfunctional blower: A bad motor or unbalanced fan may stop airflow over the evaporator coil.
