Frozen Evaporator Coil? Here’s What You Should Do Before Calling A Professional
Your air conditioner works hard to provide your family with comfortable, cool air during the high temperatures we have here in Hays County. If your AC evaporator coil freezes, you will be left sweltering in the heat without cool air and may end up dealing with expensive AC repair or replacement bills.
But you might just be able to to solve the problem yourself!
Before you call Garner Heating & Air Conditioning about your air conditioning problem, see if the evaporator coil is indeed the culprit by opening up your indoor air handler and taking a look inside. If the coil is covered with ice, follow these steps to fix your frozen evaporator coil:
The following can cause you evaporator coil to freeze:
- Your air filter is clogged or dirty.
- Your system has a refrigerant leak.
- Your evaporator coil is dirty.
Another thing that can cause your evaporator coil to freeze is if there is not enough air flow, whether it be due to a closed air vent or a broken air handler. To get your air conditioning system repaired, call us today.
To unfreeze an evaporator coil, you can:
- Turn off your air conditioner and allow your coil to dethaw naturally.
- Set your air conditioner to fan to thaw out your evaporator coil.
- Use a blow dryer to thaw out your evaporator coil.
Depending on the issue, these methods may be able to fix your evaporator coil. However, if your evaporator coil is frozen due to low levels of refrigerant, you will need to have your system’s refrigerant recharged. To get your air conditioner repaired, contact us today.
A few ways you may be able to tell if your evaporator coil is frozen include:
- Your air conditioner is not producing cool air.
- Your air conditioner has water leaks.
- Your evaporator coil has ice or moisture on it.
If you are not familiar with HVAC systems, but you believe that your evaporator coil may be frozen, you should turn off your AC unit and have an HVAC technician diagnose and repair it. To get your air conditioner repaired, give us a call today.
1. Shut down the AC unit. Use your thermostat to completely turn your system off, so that the components are not subjected to more potential stress or damage.
2. Turn on the AC system fan. Activate your system’s fan only setting so that air will still be blown on the evaporator coil. This will help the ice to melt more quickly.
3. Take a look at the blower fan. If the fan is covered in dirt, it should be cleaned by a professional HVAC technician. If you notice something seems wrong with any part of the blower setup, professional repairs might be needed.
4. Check your air filter. If your air filter is dirty, it may be causing poor air flow that leads to a frozen coil. You can easily replace the air filter yourself if it is dirty. Always remember to change your air filter on a regular basis. Check your filter every 30 days to see if it is dirty enough to warrant replacement.
5. Turn the AC back on after the ice is gone. If you took it upon yourself to perform necessary cleanings or replacements, wait until all of the ice on the evaporator coil is completely gone before starting up the AC again.
Periodically check your evaporator coil to see if it begins to freeze again. If it doesn’t freeze, great! You’ve solved the problem! However, if it does freeze again, you’ll need to call a professional HVAC technician for expert diagnosis and repair.
