How To Know If Your Refrigerant Is Low
If you experience poor air conditioner performance, you might wonder how to know if refrigerant is low. Refrigerant is the most essential element of your AC system, so if you have low refrigerant, you can’t properly cool your home.
Frozen Evaporator Coil
A frozen evaporator coil is an obvious sign you don’t have enough refrigerant in your system. The coil collects the hot air and disburses it outside, but when you’re low on refrigerant, the pressure drops and significantly lowers its temperature. Whether you notice ice buildup on the indoor evaporator coil or the outdoor unit, subpar refrigerant levels remain a common cause.
Lack of Comfort
If your air conditioner becomes low on refrigerant, you’ll experience a significant decrease in comfort.
Refrigerant leaks can manifest in the following ways:
- Inability to blow cool air
- Longer cooling times
- Reduced or low airflow
- Constantly running without reaching your desired indoor air temperature
An HVAC professional can repair or refill refrigerant lines and help keep your home cool.

Higher Air Conditioner Bills
If you wonder how to know if refrigerant is low, keep an eye on your electric bills. When your air conditioner is low on refrigerant, it may still cool your home to a comfortable temperature, but it must work harder to do so.
Increasing bills don’t always mean your AC unit needs more refrigerant. However, it does mean you need an AC technician to determine the exact nature of your air conditioner problems.
Concerning Air Conditioning System Noises
When air conditioners make a hissing or bubbling noise, it means you have a leak in your air conditioner’s refrigerant line. Only an HVAC technician can repair refrigerant lines, as it requires special training to find and repair. Refrigerant also contains dangerous toxins, so you need a professional to handle it properly.
Short Cycling
When your air conditioner turns on and off quickly, experts call it short cycling. It can indicate any number of problems, including a low refrigerant level.
Short cycling occurs when your system encounters a problem, shuts off, and then turns back on when the problem resolves itself. Low refrigerant levels can cause the lines to freeze or the system to overheat. Once the temperature levels off, the device turns on until the problem occurs again.
Water Leaks
If you notice a water leak beneath your AC unit, one likely cause is low refrigerant. If you notice water pooling beneath your device, call for help immediately.
The evidence may not manifest in such an obvious way. For example, you may notice condensation on your device rather than a large pool of water. You may also notice leaking refrigerant, which can smell like sugar water or nail polish remover.
