Is Your AC Not Cooling? This Could Be Why
If your air conditioner suddenly stops cooling your home like it used to, you may be asking yourself, what to do if refrigerant level is low? Low refrigerant is a common AC problem that can make your system inefficient, drive up your electric bill, and even damage your compressor if ignored.
Let’s break down the warning signs, what causes it, and what to do next before it becomes a much bigger (and more expensive) issue.
Signs Your AC Refrigerant Is Low
Wondering how to tell if your AC is low on refrigerant? Here are the most common red flags:
- AC blowing warm air even when the thermostat is set to cool
- Increased run times or AC that struggles to maintain temperature
- Ice on the refrigerant line or evaporator coil
- Hissing or bubbling sounds, which may signal a refrigerant leak
- Higher than normal energy bills with no other explanation
If you notice any of these issues, it’s time to call a professional for an AC inspection.
What to Do if Refrigerant Level Is Low
If you suspect your system is low on refrigerant, don’t try to top it off yourself. Refrigerant handling requires EPA-certified technicians and should always be done professionally. Here’s what to do:
- Turn off your AC to prevent further damage, especially if you see ice buildup.
- Schedule an inspection with a licensed HVAC technician.
- Have the leak located and repaired—this is essential. Simply refilling the refrigerant without fixing the leak is a short-term and costly mistake.
- Recharge the system with the correct amount of refrigerant once repairs are made.
- Consider regular maintenance to prevent future refrigerant issues and ensure efficient performance.
What Causes Low Refrigerant?
Refrigerant isn’t used up over time like gas in a car—it circulates in a closed loop. So, if your AC is low, there’s a leak. Common causes include:
- Worn-out joints or connections
- Corrosion in the coil
- Physical damage from debris or impact
- Improper installation or faulty service work

FAQs
What to do if refrigerant levels are low?
If your refrigerant levels are low, your AC may struggle to cool properly, freeze up, or even overheat. The best course of action is to have a licensed HVAC technician inspect for refrigerant leaks, repair any damage, and recharge the system with the correct type and amount of refrigerant. Attempting to refill refrigerant without fixing the root cause—usually a leak—can lead to recurring problems and higher energy bills.
Can you recover refrigerant from the low side?
Refrigerant recovery should only be handled by certified HVAC professionals. While recovery from the low-pressure side is possible in some systems, it requires specialized equipment and must be done safely and legally to avoid environmental harm. Improper handling can damage your system or violate EPA regulations.
Can I run AC with low refrigerant?
Running your air conditioner with low refrigerant is not recommended. It can cause the system to overwork, freeze the evaporator coil, reduce energy efficiency, and potentially damage the compressor. If your AC is short cycling or blowing warm air, it’s likely a refrigerant issue—and time to schedule a professional checkup.
What happens if you run out of refrigerant?
If your system runs out of refrigerant entirely, it won’t be able to cool your home. Worse, continued operation may lead to system breakdowns or costly compressor failure. You’ll likely notice your AC blowing warm air, strange hissing noises, or ice buildup on the lines or coils.
How much does it cost to fix low refrigerant in AC?
The cost to fix low refrigerant in your AC varies depending on the type of refrigerant used, the extent of the leak, and labor. A basic refrigerant recharge may cost $100–$400, while leak detection and repair can add to the total. If you’re using an older system with phased-out refrigerants like R-22, costs may be higher.
