With a little knowledge, you’ll realize that AC systems are one of the simplest equipment to deal with. Every issue they encounter starts small. All you need to know is how to identify the early warning signs and take quick action before they escalate. Here are some basic solutions for the most common AC problems homeowners experience.
AC Won’t Turn On
If your AC isn’t turning on, check the thermostat first. Someone may have changed the settings to a higher temperature or accidentally switched it off. Ensure the thermostat is set to “Cool” mode and, for optimal efficiency, use the “Auto” setting. Consider changing the device’s battery because low power can prevent the thermostat from functioning correctly.
If the thermostat and battery seem fine, check the circuit breaker. Power surges and overloads can cause the circuit breaker to trip. Reset it and see if your AC is working again. However, make sure to understand the reason behind the power surges. Your AC might be drawing too much power because of a faulty component or struggling to maintain efficiency as it ages. Loose wiring could also cause power surges.
AC Isn’t Blowing Cool Air
If your AC is blowing room temperature or warm air, you can diagnose the issue in a few steps. First, check the thermostat to see if it’s in “Fan On” mode. The “Fan On” mode keeps the fans running even when the system is off. Switch the setting to “Auto” mode to resolve the issue.
If the problem persists, inspect the filters at the vents or indoor units, depending on the type of your system. Dirty filters can prevent air from flowing properly, causing hot air to stay longer, creating the warm effect. Clean or replace the filters as needed to restore airflow.
Next, check the outdoor condenser unit for debris. Leaves, twigs, and dust may block ventilation, preventing the system from cooling effectively. Note that, once the refrigerant extracts heat from the indoor air, it travels to the condenser to dispel the heat outside. If the condenser coils are dirty, the heat exchange process becomes inefficient. To resolve this, carefully clean the condenser and ensure it has at least 12 inches of space on all sides, including the top.
If your AC is still not blowing cool air, call a qualified HVAC technician for further diagnosis. You may have a refrigerant leak. Refrigerant is so toxic that professionals need EPA certification just to handle it. Trying to top it up or repair a leak on your own will not only lead to serious health hazards but also cause further system damage.
AC Is Making Strange Noises
Strange noises from your AC are typically symptoms of already existing problems. You can identify the underlying issue by the type of noise your unit makes. For example, banging or rattling sounds indicate something is loose or broken within the system. Whining noise usually stems from a worn-out fan belt or motor, while buzzing sounds suggest an electrical problem.
Regardless of the type of sound, turn off your system and call for professional assistance. Continuing to use the AC will only exacerbate the problem.
AC Produces Bad Smells
An AC is a comfort system; it’s supposed to make your indoor air cleaner and fresher instead of polluting it. So, again, if your unit produces weird odors, you already have a problem that is just announcing itself now.
A stale and musty smell could suggest that mold, mildew, fungi, or bacteria are growing in your ducts, filters, or around your AC. A sharp, burning plastic or metallic scent indicates overheating or electrical wires burning inside your AC. Rotten egg odor could signal that an animal trapped inside your duct is rotting. Lastly, a sweet, chemical smell indicates that you could have a refrigerant leak.
AC Consumes Too Much Power
If you are experiencing a sudden spike in your system’s energy consumption, it means efficiency is compromised. Factors such as dirty filters, air leaks, old age, or blocked vents could be forcing your AC to work harder than necessary. This strain translates into excessive energy use.
Before you call an HVAC technician for a diagnosis, be sure to rule out poor insulation. Your AC might be operating correctly, but your home could be losing cool air or gaining unwanted heat through poorly sealed windows, doors, attic, or ductwork.
