How Can You Defrost The AC Coils Of Your Air Conditioner?
To begin, switch off the air conditioner and let the frozen evaporator coils defrost. You may accomplish this by turning off the circuit breaker on the unit. The coils might take up to 24 hours to completely thaw if left to their own devices.
Here’s what you should do to keep the air conditioner from freezing:
- Make sure the refrigerant level is correct.
- Replace the filter every month.
- Keep the supply vents open at all times.
- Increase the fan’s speed.
- Make that the thermostat is in good working order.
- Weekly inspect the condensate drain.
- Check to see whether any of your window units are correctly aligned.

Issues That You May Discover While Replacing Your Filter
Problems with your filter, in addition to your AC coils, could cause your system to freeze up. That’s why it’s important to get regular maintenance on your AC unit. When homeowners change their air filters, they may uncover problems with their air conditioner.
If you detect these problems, you should call a professional as soon as possible to get them fixed.
- Excessive dust in return ducts: Do you detect a coating of dust within the air duct when you remove the return vent grille?
If that’s the case, your ducts are probably filthy. Leaks in the ductwork are the most common source of extremely filthy ducts.
If your ducts are leaking, dust from unconditioned places such as attics and walls can readily infiltrate them. When you operate your air conditioner, this dust is pushed into your home, where it typically gathers around the return vent.
Contact Comfort Solutions Heating/Cooling & Duct Cleaning for AC repair in Cincinnati, OH. If you see a lot of dust:
- Your ducts should be cleaned.
- Check for leaks in your ductwork. They’ll use mastic sealant or metal tape to patch any leaks or holes they detect (in a process called duct sealing).
If your house has duct leaks, don’t be surprised—according to ENERGY STAR, most homes lose 20–30% of the air that travels through the ducts due to leaks, holes, or improperly connected ducts.
- Water around the air handler: You may notice water surrounding your air handler if your air filter is placed in the attic or basement near the air handler.
You most likely have one of these three AC problems if there is water near the air handler:
- An evaporator coil that has frozen: The evaporator coil, which is located in the air handler, collects moisture from your home’s warm, humid air. However, if your system has limited airflow or low refrigerant (the liquid that cools the air), the moisture might freeze on the coils. As the ice melts, it drops into the drain pan, overflowing and forming puddles surrounding the air handler.
If you detect ice on the evaporator coil or one of these four symptoms, you’ll need to contact a professional to diagnose and repair any poor airflow or refrigerant issues.
- A blocked condensate line is number two: The condensate line gathers moisture from the evaporator coil and sends it outside. If it becomes clogged, it may overflow, causing pools to form around your air handler.
- A dripping drain pan: The drain pan of your air conditioner collects moisture that drips from the evaporator coil. Water will gather around your air handler if the pan rusts and leaks.
To repair a broken drain pan, go to your local home improvement store and get a new one. Are you unsure which drain pan to purchase? Simply call a professional or seek assistance from a store clerk. (Before you go to the store, make sure you know the brand and model of your air conditioner.)
