Refrigerant leaks are one of the most common — and most critical — issues that can affect your air conditioner. Left unchecked, an AC refrigerant leak can compromise your cooling performance, spike energy costs, damage your system, and even pose health and environmental risks.
In this guide, Burgeson’s Heating, A/C, Electrical, Solar & Plumbing explains how refrigerant works, how to detect refrigerant leaks, and what steps you should take if you suspect an issue.

What Is Refrigerant and What Does It Do?
Refrigerant is the lifeblood of your air conditioning system. It circulates through coils and lines, absorbing heat from indoor air and releasing it outdoors — effectively cooling your home.
Common types of refrigerants include R-410A (used in most current systems) and R-22 (now phased out due to environmental regulations). Whether your system uses older or newer refrigerant, a refrigerant leak can prevent your AC from functioning properly and should be addressed immediately.
Common Signs of a Refrigerant Leak
How do you know if you're dealing with an air conditioner refrigerant leak? Here are the most common warning signs to look out for:
Weak or Warm Airflow From Vents
If the air coming from your vents feels lukewarm or significantly weaker than usual, you may have an AC refrigerant leak. Low refrigerant levels reduce the system’s ability to cool efficiently.
Longer Cooling Cycles or Inconsistent Temperatures
Does your AC seem to run non-stop? Refrigerant leaks force your system to work harder to maintain your desired temperature, resulting in longer cycles and uneven cooling throughout the home.
Higher Energy Bills Without Increased Usage
An unexplained spike in energy bills could be your AC overcompensating for lost refrigerant. Detecting refrigerant leaks early can help you avoid unnecessary energy waste.
ICE BUILDUP ON REFRIGERANT LINES OR EVAPORATOR COIL
Ice forming on your indoor or outdoor coils may indicate a leak. Without enough refrigerant to absorb heat, condensation on the coils can freeze — a common side effect of an air conditioner refrigerant leak.
HISSING OR BUBBLING NOISES FROM THE UNIT
Refrigerant escapes in gas or liquid form, often producing a hissing or bubbling sound. If you hear this noise near your AC unit, it’s time to call Burgeson’s Heating, A/C, Electrical, Solar & Plumbing for professional diagnosis.
AC NOT COOLING LIKE IT USED TO
If your home just isn’t as cool or comfortable as it used to be, a refrigerant leak could be the root cause. The system can’t cool properly without the right refrigerant charge.
WHY REFRIGERANT LEAKS ARE A BIG DEAL
An AC refrigerant leak is more than a simple maintenance issue. It can lead to serious consequences, including:
1. Compressor Damage: Without enough refrigerant, your compressor can overheat and fail — one of the most expensive repairs in an AC system.
2. Reduced Energy Efficiency: A leaking system works harder, consuming more electricity and delivering less comfort.
3. Environmental Impact: Older refrigerants (like R-22) are harmful to the ozone layer, while even modern HFCs contribute to global warming.
4. Health & Safety Risks: In rare cases, leaking refrigerant in enclosed spaces can cause headaches, nausea, or dizziness if inhaled.
WHAT TO DO IF YOU SUSPECT A LEAK
If you notice any of the signs above:
1. Turn off your AC system to prevent further damage.
2. Call a licensed HVAC professional like Burgeson’s Heating, A/C, Electrical, Solar & Plumbing.
3. We’ll perform precise leak detection, seal or replace damaged components, and safely recharge your system with the correct amount of refrigerant.
AVOID DIY SOLUTIONS:
Refrigerant handling requires EPA certification. Overcharging or undercharging your system can do more harm than good.
HOW TO PREVENT FUTURE LEAKS
Refrigerant issues can often be avoided with proactive care. Here's how:
1. Schedule regular AC maintenance with a trusted provider like Burgeson’s Heating, A/C, Electrical, Solar & Plumbing.
2. Replace aging coils and components before they wear out.
3. Ensure professional installation to avoid stress cracks or poor sealing on lines and joints.
