Here’s the thing–if you are asking yourself this question, the answer is probably no.
Now, there is no such thing as a silent air conditioner. You will likely always hear the compressor cycling on and off if you’re near the outdoor unit. When your indoors, you’ll hear the air coming through your vents, and you might even detect your ductwork flexing as temperatures fluctuate.
But if you hear anything unfamiliar, you’re right to be concerned! It warrants at least a call to an HVAC professional to determine what’s going on and how to remedy it. Read on as we uncover some of the common noises we get called about, and why they’re bad news.
Hissing or Bubbling
This is indicative of a refrigerant leak. Refrigerant is a vital component in your air conditioner–it’s what makes the cooling process possible! Upon manufacturing, your air conditioner is filled (charged) with enough refrigerant to last its entire lifespan. It’s not something that depletes like a fluid, but rather it’s in a closed-loop system.
It is possible, however, for your refrigerant line or evaporator coil to spring a leak, particularly if you have an aging air conditioner. Depending on where the leak is located, you’ll either hear hissing–like air being let out of a tire–if it’s in its gas form, or bubbling/gurgling if it’s in its liquid form. Beware of these AC sounds, as catching them early can prevent major breakdowns.
A refrigerant leak can and will wreak havoc on your air conditioner, and can lead to permanent compressor damage, which would result in a complete system breakdown. So if you suspect a refrigerant leak, the best thing you can do is give us a call!
Grinding
This sound is likely coming from the air handler. This is the component of your cooling system responsible for circulating the cooled air throughout your living space as the system runs. The air handler motor goes under a lot of stress and to help it cope it’s equipped with a number of oiled bearings.
Eventually, these bearings wear down, increasing friction. If you hear grinding noises, it’s crucial to act before the system overheats. Don’t ignore late-season HVAC issues—they can escalate quickly and lead to costly repairs. You’ll know this friction is occurring if you hear a grinding noise coming from your air conditioner.
Short-Cycling
Short-cycling occurs when the air conditioner’s compressor rapidly turns on and off. It may result from an installation error or even something as simple as a clogged air filter. If you’ve been considering upgrading your system, going ductless this summer can provide a more efficient solution and prevent short-cycling issues.
What’s happening is something–whether an electrical issue, installation error, or clogged air filter–isn’t allowing your air conditioner to complete a full cooling cycle. Short-cycling is both the symptom of a problem and the cause of further problems. If you hear your system doing this, please don’t hesitate to reach out!
