Spotting ice on your air conditioner might seem odd—after all, AC units are supposed to cool your home, not freeze themselves. If you’ve recently noticed frost or ice buildup on your system, don’t ignore it. While it may not always mean a major problem, it’s definitely a sign that something isn’t working as it should. Whether you rely on your system daily or seasonally, maintaining reliable air conditioning in Montville, NJ, means knowing how to respond when something goes wrong.
Step 1
First things first: turn the system off immediately. Running an air conditioner with ice on it can cause further damage to the compressor or other internal components. Next, allow the ice to melt completely. This can take several hours, so be patient. While waiting, keep an eye on the drainage around your indoor unit. As the ice melts, the excess water needs somewhere to go. Make sure the condensate drain is working properly and monitor the area to avoid water damage to floors, ceilings, or walls.
Step 2
Once all the ice has melted, clean the evaporator coils if you can access them. Ice can often form because the coils are dirty and can’t absorb heat effectively. A gentle brush or coil cleaner can remove dust and grime that’s blocking airflow. You’ll also want to check the air filter—if it’s dirty or clogged, replace it immediately. Proper airflow is crucial to your AC’s operation, and restricted air movement is one of the most common reasons ice forms in the first place.
Step 3
Now it’s time for the test: turn your air conditioner back on. Let it run and keep a close eye on it for the next few hours. If the system seems to be cooling normally and no ice returns, the issue may have been temporary—possibly due to a dirty coil or filter.
However, if the ice builds up again, it’s time to call in the professionals. Recurring icing usually indicates a deeper issue that needs expert attention. Our team is fully equipped to diagnose and resolve persistent AC icing problems.
Common Causes of Repeated AC Icing
- Low refrigerant levels: Often due to a leak, this can prevent the system from absorbing heat properly, leading to freezing.
- Faulty blower fan: If the fan isn’t pushing enough air across the coils, they can get too cold and start freezing up.
- Dirty or blocked ductwork: Restricted airflow anywhere in the system contributes to temperature imbalances and icing.
- Thermostat problems: A malfunctioning thermostat can cause the system to run too long or at inappropriate temperatures.
- Mechanical failures: Issues with the expansion valve or other internal components may lead to frost buildup.
