When the summer heat hits the South Suburbs and Chicagoland, there’s nothing worse than an air conditioner that won’t keep up. At Doornbos Heating & Air Conditioning, we know just how important it is to keep your home or business cool and comfortable. We’ve proudly served our neighbors since 1927, and we’re here to help you handle the most common AC problems before they turn into big headaches.
Inconsistent Cooling Around the House
Do some rooms in your home feel like a freezer while others are too warm? You’re not alone—uneven cooling is a common complaint. In many cases, this could be caused by a leak or blockage in your ductwork. Older homes or poorly insulated rooms may also be to blame.
If this sounds familiar, one of our trained technicians can inspect your system and offer simple solutions—like duct sealing or improved airflow—to even out the temperature throughout your space.
AC Blowing Warm Air
If your air conditioner is on but blowing warm air, the first thing to check is the air filter. A dirty filter blocks airflow and makes your system work harder than it should. Swapping it out every few months is one of the easiest and most affordable ways to improve your cooling power.
If that doesn’t solve the issue, the problem could be dirty condenser coils or low refrigerant levels from a leak. Don’t worry—we’ve got the tools and know-how to get your system cooling again in no time.
Quick tip: Keeping up with regular AC maintenance can help prevent most cooling issues before they start.
No Airflow from the Vents
If you turn your AC on and nothing comes out of the vents, check your thermostat and circuit breaker first. A simple reset could be all you need. But if the system still isn’t pushing air, the fan motor or blower belt might be broken.
While some fixes can be DIY, others—like electrical problems—are better left to our licensed professionals. We’ll diagnose the issue and get your cool air flowing again quickly.
Ice on the Air Conditioner
Seeing ice buildup on your unit is never a good sign. It usually means something is blocking airflow. Start by checking your air filter, open vents, and making sure nothing is in the way of the ducts.
Still frozen? It could be low refrigerant or a bigger system issue. Contact us today, and we’ll safely thaw things out and find the cause.
Strange Noises from Your AC
Is your air conditioner making weird sounds like squeaking, grinding, or rattling? These noises often mean something’s loose, worn out, or off track.
- Squeaks usually point to a worn belt
- Grinding might mean motor bearings are failing
- Rattling can be as simple as a loose cover
It’s best to catch these issues early—before a small repair turns into a costly breakdown.
Your AC Won’t Turn Off
Your air conditioner should turn on, run for a while, and then shut off. If it’s running constantly, or cycling on and off too much, something isn’t right. The fan, thermostat, or even refrigerant levels could be to blame.
In other cases, a dirty condenser or blocked evaporator coil could be the issue. Doornbos will give your system a full checkup and cleaning to get it back in top shape.
