Noticed ice forming on your air conditioner? It might look harmless—or even refreshing on a hot Alabama day—but it’s actually a sign that something’s wrong. At Thomas Service Company, we’ve seen this issue time and time again, and we’re here to explain why ignoring it can lead to bigger problems for your AC system and your home’s comfort.
What Causes Ice on an AC Unit?
Ice buildup can form on either the indoor evaporator coil or the outdoor unit. Some of the most common causes include:
Restricted airflow: Dirty air filters, blocked vents, or clogged ductwork can all reduce airflow, preventing the evaporator coil from absorbing enough heat. As a result, the coil gets too cold and condensation freezes on the surface.
Low refrigerant levels: If your system is low on refrigerant—often due to a leak—it can’t absorb heat effectively. This drop in temperature can also lead to ice formation.
Thermostat or fan problems: If your fan isn’t running at the right speed or your thermostat is malfunctioning, your system may cycle improperly, causing temperature imbalances that result in ice.
Why You Shouldn’t Ignore It
While it might seem like a minor issue, ice on your air conditioner is a red flag that should never be ignored. Here’s why:
Decreased efficiency: Ice on the coils interferes with the cooling process, making your AC work harder to cool your home. That means longer run times, higher energy bills, and more wear and tear on your system.
Risk of complete system failure: If left untreated, the underlying issue can cause major damage. Refrigerant leaks, for example, can lead to compressor failure—one of the most expensive repairs you could face.
Comfort problems: When your AC is iced over, it won’t cool your home properly. You’ll end up with uneven temperatures and increased humidity, making your home far less comfortable.
Increased repair costs: Catching the issue early could mean a quick fix like changing a filter or topping off refrigerant. Ignoring it could mean a full system replacement down the road.
What to Do if You See Ice
If you spot ice on your AC unit, turn the system off immediately and let it thaw. Then, call the HVAC professionals at Thomas Service Company to inspect and diagnose the issue. We’ll perform a thorough evaluation to find out what’s causing the freeze and recommend the best solution to get your system back on track.
