AC Refrigerant Leaks: The Basics

When it comes to household air conditioning systems, there are a lot of things that you may need to have addressed. For example, annual maintenance and cleaning, air filter changes, and more. One of the most common, and concerning, issues you might encounter is a refrigerant leak. Here's a look at what you need to know to recognize the potential signs of a refrigerant leak and address it right away.

Warmer Air

Your air conditioner should, ideally, blow cold air when it's engaged to cool down your home. If you notice that the air blowing through the vents is warmer than it used to be, that's a possible sign that you may have a refrigerant leak. When your air conditioner doesn't have sufficient refrigerant in the system, it's cooling capabilities are reduced and the air passes through far warmer than it should.

Reduced Air Volume

You've probably grown fairly accustomed to a specific amount of air coming from your air conditioning vents when the system is running. If your air conditioner grows low on refrigerant, it won't be able to put as much air through the system, resulting in lower air volume coming through the air vents. If you notice that your air conditioner isn't blowing as much air as it used to, even if that air is cold, you may have a refrigerant leak.

Frozen Coils And Lines

When your air conditioning system is low on refrigerant, the lines and coils are unable to absorb as much heat as they should from the air. As a result, the condensation in the system freezes onto the coils and the lines. If you're noticing ice buildup on the coils, that's a sign that you need to have the refrigerant pressure tested.

Greasy Spots On Your Air Conditioner

As the refrigerant reaches the warmer temperatures outside, it becomes a liquid. It also leaves a greasy residue behind when it leaks on your air conditioner. Check the unit outside, including all of the surfaces, for any signs of greasy residue. If you see any, call an air conditioning service technician right away.

Noises Around The Air Conditioner

An air conditioner that's leaking refrigerant can sometimes make hissing or bubbling sounds as the refrigerant leaks out. This is most common with smaller leaks because of the pressure behind the refrigerant as it's leaking out. Stand near your air conditioner when it isn't running and listen for any obvious sounds of a leak.

These are a few of the most common signs to watch for when you're worried about an air conditioning refrigerant leak. Talk with an air conditioning service near you today for more information.
