Is it normal for an AC unit to make noise?
You’ll likely hear your air conditioner make a series of clicking noises after completing a cooling cycle. This is normal. What you’re hearing is the machinery coming to a stop. A constant clicking noise, however, can be a sign of a failing thermostat or an object stuck in the fan assembly.
Where does the noise come from on an air conditioner?
In most new air conditioners, the bulk of the noise comes from the compressor. You can remove the top of your A/C outdoor unit and install a sound blanket over the compressor — it just sits right on top of it. This will muffle much of the sound of the unit.
Why do I hear a hiss in my air conditioner?
If the condenser fan does not operate (to condense high pressure high temperature refrigerant gas back to a liquid) high pressures develop on the outlet side of the compressor. Check the fan start-run capacitor and the fan motor. Abnormal and very-high pressures in the compressor motor, possibly heard as a combined hiss and shriek.
What do you need to know about air conditioner vents?
Unless you spend a lot of time huddled under your sofa, you’ll want to be sure your AC vents are unobstructed. If AC vents are open in every room of your house, you’re chilling a lot of real estate that may not be in use on a day-to-day basis.

What happens if the air conditioner compressor is not working?
If the compressor motor is not working, then the air conditioner will not cool. If the outside fan is not working the compressor may cause problems and will short cycle or cease working. If the indoor fan stops, you’ll find that there is no air blowing through the vents. If playback doesn’t begin shortly, try restarting your device.
