As the warmer weather approaches, it’s time to turn your air conditioner on for the first time in months. But before you sit back and enjoy the cool air, it’s important to pay attention to how your system is running.
ACs and heat pumps can show early signs of trouble, and catching any issues now can prevent bigger, more expensive repairs later in the season. Keep reading to learn some common warning signs that your AC may need professional attention.
Weak or Warm Airflow
When you turn on your AC, pay close attention to the airflow coming from your vents. If the air feels weak or isn’t as cool as expected, there could be an issue with your system. A clogged air filter, ductwork problems, or a failing compressor could all be to blame.
Weak airflow reduces efficiency and makes it harder for your AC to cool your home, leading to longer run times and higher energy bills. Replacing your air filter is a good first step, but if the problem persists, it’s best to schedule a professional inspection.
Unusual Noises Coming from the Unit
Your AC should run relatively quietly, with only a soft hum from the fan or compressor. If you notice unusual sounds—such as banging, rattling, hissing, or screeching—your system may have a loose or damaged component.
Banging noises often indicate a broken part, while hissing could indicate a refrigerant leak. A screeching sound may signal a motor issue or a worn-out belt. Ignoring these noises can lead to further damage, so it’s important to address them early with professional repairs.
Foul or Musty Odors
It’s normal for the air to smell stale when you first turn your AC on for the season. The smell shouldn’t last long as air flushes through the system. However, if it persists during additional cooling cycles, that is a problem.
A strong, musty odor when you first turn on your AC can be a sign of mold or mildew growth in your ductwork or air handler. This often happens when moisture builds up inside the system during the off-season.
Burning smells, on the other hand, could indicate an electrical issue, such as overheating wires or a failing motor. If you detect any unusual odors, turn off your system and have it inspected to prevent potential health hazards or fire risks.
Short Cycling or Constant Running
Does your AC turn on and off frequently, or does it seem to run nonstop? Both short cycling and extended run times can indicate a problem. Short cycling—where the AC turns off too quickly before cooling your home—can be caused by a faulty thermostat, a refrigerant leak, or an oversized unit.
If your system runs constantly, it may be struggling to reach the set temperature due to low refrigerant levels, dirty coils, or an aging compressor. Any of these issues can lead to increased wear and tear, reducing your system’s lifespan or leading to a total breakdown.
