AC Troubleshooting Guide
AC Troubleshooting Guide for Homeowners Around Naperville: Why Is My AC Not Working?
If your AC isn’t doing its job on a hot Naperville day, you’re not alone—and you’re definitely not imagining things. Whether your AC is not blowing cold air, making noise, or simply not working at all, there are a few common issues that could be behind it.
At Leipart Heating and Cooling, we help homeowners across Naperville, Aurora, Bolingbrook, Plainfield, and nearby communities troubleshoot and fix their AC problems fast. Below, we’ll walk you through a few things you can check yourself—and when it’s time to call in the pros.
AC Not Blowing Cold Air?
When your AC is running, but the air coming out feels warm or just not cool enough, it can be incredibly frustrating. Here are a few common causes:
- Low refrigerant – A refrigerant leak is one of the top reasons for AC systems not cooling properly. If your system is low, it simply can’t cool the air.
- Dirty air filter – A clogged or dusty filter restricts airflow and can cause the system to blow warmer air.
- Frozen evaporator coil – This can happen when there’s restricted airflow or low refrigerant, and it stops the cooling process entirely.
- Thermostat issues – Sometimes, it’s as simple as incorrect settings or a malfunctioning thermostat.
DIY Tip: Try replacing your air filter first—this is one of the easiest and most cost-effective ways to improve airflow and cooling performance.
AC Making Noise?
A little noise is normal, but if your AC is rattling, hissing, buzzing, or grinding, it may be trying to tell you something:
- Rattling or banging – Could mean loose parts or debris inside the outdoor unit.
- Hissing – Often points to a refrigerant leak, which can affect performance and safety.
- Buzzing or humming – May be due to electrical issues or a failing capacitor.
- Grinding – This sound usually comes from worn-out motor bearings and shouldn’t be ignored.
Pro Tip: If your AC is making unusual noises, turn it off and schedule a professional inspection before the issue worsens or leads to permanent damage.
AC Not Working at All?
When your AC won’t turn on—no fans, no cooling, nothing—it might be caused by:
- Tripped breaker or blown fuse
- Faulty thermostat or dead batteries
- Disconnected wiring
- Malfunctioning capacitor or compressor
Check This First: Make sure the breaker for your AC hasn’t tripped and that your thermostat has fresh batteries. If that doesn’t work, it’s best to have a licensed tech take a look.
