When the summer heat rolls into Vernon Hills, IL, the last thing anyone wants is an air conditioner that can’t keep up. While it’s common to check the thermostat, replace filters, or top off refrigerant, there’s one part that often gets overlooked: the AC capacitor. If your cooling system isn’t doing its job, a failing capacitor could be the culprit. Let’s walk through the warning signs and why quick action can make all the difference.
What Your AC Capacitor Actually Does
Inside every AC system, capacitors play a key role in powering up and running the motors. Most units use two: a start capacitor and a run capacitor. The start capacitor delivers that burst of electricity needed to get things moving, like the compressor and fan motors. The run capacitor steps in after that, helping everything run smoothly and efficiently throughout the cooling cycle. If either one fails, your air conditioner won’t be able to do its job properly.
Telltale Signs Your Capacitor Might Be Failing
Capacitor issues can look a lot like other system problems, which makes them tricky to spot at first. Here are some common red flags to keep in mind:
-
Your AC struggles to turn on or won’t start at all
-
You hear unusual humming or clicking from the unit
-
The system randomly shuts off
-
Warm air is blowing out instead of cold
-
Your energy bills are creeping up for no clear reason
If any of these sound familiar, it’s smart to get your system checked before things get worse.
What Causes a Capacitor to Go Bad?
Several things can wear down a capacitor over time. In Vernon Hills, those hot summer days can push components to their limit, This is especially true when your AC runs long hours. Power surges, frequent start-stop cycles, and everyday wear and tear can all take a toll. On top of that, neglected maintenance like clogged filters or dirty coils can force the system to work harder, which adds even more strain.
Why It’s Important to Act Quickly
A bad capacitor isn’t just an inconvenience, it can lead to major system damage. Without it, the compressor or fan motor might overheat or quit altogether. What could’ve been a simple $100 to $300 fix might turn into an extremely costly repair. Catching the issue early helps protect your comfort and your wallet.
