Dealing with HVAC Noises
The HVAC Equipment can create random noises, and sometimes, even a continuous humming sound. (Photo Credits)
A humming noise coming from the HVAC is not just annoying, it can also be an issue that merits the attention of the homeowner. So what does a humming HVAC mean?
American Home Shield says humming noises coming from a home HVAC system is not much of a huge concern. It however may mean that it needs a maintenance check. Plumbing Association of San Diego
"A humming sound generally isn't serious, but it still signals that something inside your air conditioner is off. Loose parts and refrigerant piping can cause vibration and, if left unchecked, can lead to a more serious maintenance issue. Sometimes humming or buzzing noises point to electrical problems. If the compressor hums and refuses to start, there may be an issue with the motor, though loose wiring could trigger this noise, too."

Read about the other HVAC noises and what they mean in AHS' original article here.
Other HVAC Sounds
Angie's List meanwhile rounded up the different sounds that may come from an HVAC system. The sounds that they mentioned in their article though are sounds that ring an alarm bell for any homeowner. Rattling noises is among the type of HVAC noises that are included in their list. A/C And HVAC
"Loud rattling, thumping, clanking or banging noises. These sounds usually indicate a problem with the blower assembly or motor. Rattling usually means that a component in the system is coming loose. The problem should be repaired before the part breaks or disconnects completely. If you hear louder banging sounds when the blower is running, shut the system off. At this point, something has broken or disconnected. Occasionally, the motor mounts on the assembly can become loose. The blower may also be out of alignment. Unusual rattling sounds can come from motor bearings. The motor assembly should be inspected by a qualified technician."

Compact Appliance also came up with a write-up explaining the meaning and causes of each non-normal noise that may emanate from an HVAC Unit. Humming from the outdoor unit is one of the type of noises explained in the write-up.
"Even with a completely dead capacitor, your compressor will still attempt to use it as a power source. This can burn out the entire compressor, leading to costly repairs. If your HVAC will not turn on and the clicking sound has turned into a hum, this very likely indicates that your capacitor is no longer providing power. In this case, turn your unit off immediately to prevent any further damage.
Often, these parts will fail during the most blistering parts of the summer. Warmer months means that your HVAC must work harder than ever, and this may put an increased amount of stress on already vulnerable parts. It is during these times when a well functioning air conditioning unit means the most to you that you may have to wait to longest for an HVAC specialist to become available, so it is important to act as soon as you sense a problem."
