Decoding HVAC Noises: What Your Morristown AC is Telling You

Everyday AC Noises and Their Meanings

Identifying the type of noise your air conditioner makes is the first step in diagnosing potential issues. Here are some of the most common sounds you may hear from your AC unit:

1. Banging or Clanking

Loud banging or clanking noises often signal a severe problem with your AC’s compressor or blower assembly. These sounds may indicate that a part, such as a connecting rod, piston pin, or crankshaft, has come loose. In some cases, the compressor itself may have failed. If you hear these noises, shut off your AC immediately and call a Morristown HVAC technician for AC repair.

2. Buzzing

Buzzing sounds can have several causes, ranging from minor to severe. A buzzing noise may be due to loose parts, refrigerant leaks, a dirty condenser coil, or an electrical issue. If the buzzing comes from your outdoor unit, it could be a sign that the capacitor or contactor is failing. An AC technician can diagnose the problem and recommend the appropriate AC repair.

3. Clicking

Occasional clicking sounds as your AC starts up or shuts down are normal. However, constant or repetitive clicking may indicate an electrical problem, such as a defective thermostat or a failing capacitor. If the clicking is accompanied by your AC not turning on, it’s time to call in an AC contractor for further investigation.

4. Hissing

A hissing noise often points to a refrigerant leak in your AC system. Refrigerant leaks not only diminish your air conditioner’s cooling performance. Still, it can also cause damage to the compressor if left unchecked. If you suspect a refrigerant leak, promptly contact an AC fixer in New Jersey for AC repair.

5. Screeching or Squealing

High-pitched screeching or squealing sounds usually indicate a problem with your AC’s blower motor or fan belt. The belt may have slipped out of place or become worn, or the motor bearings may fail. These issues require attention from an AC repairman to prevent further damage to your system.

When to Call a Morristown HVAC Technician

While some AC noises may not require immediate action, others can signal serious issues that demand professional attention. If you notice any of the following, it’s time to call a Morristown HVAC technician for AC repair:

  • Loud or unusual noises that persist or worsen over time

  • Decreased cooling performance accompanied by strange sounds 

  • AC unit that won’t turn on or cycles off frequently

  • Foul odors coming from your vents along with abnormal noises

Addressing HVAC issues promptly can help prevent more extensive damage and costly repairs. Regular maintenance by a qualified AC technician can also help identify potential problems before they escalate, keeping your system running smoothly and efficiently.
