Signs Your AC Has a Refrigerant Leak

A refrigerant leak is something homeowners do not want to ignore. Not only will it prevent your AC unit from working properly, but also it can have some serious health effects such as refrigerant poisoning caused by inhaling the leaking gas or fluid. Typically, a refrigerant (or freon) leak will be caused by damage to the evaporator coils. Damage due to improper handling and corrosion are both common ways a leak can start. Regardless of how a leak was caused, it will need to be repaired immediately.

  • Lack of Cool Air - When your thermostat is set to a level you normally enjoy, but the space is still warm it could indicate a freon leak. The refrigerant coils in your AC is what cools the warm air in your home. When there is a freon leak, the refrigerant coils will not cool the air sufficiently.
  • Increased Energy Bills - When you have a freon leak, the refrigerant coils need to work harder in order to cool the warm air. This is going to cause an increase in your energy bills.
  • Hissing - Corrosion is one of the more common reasons you could have a refrigerant leak. Corrosion can cause small tears and holes in the coil line itself which can lead to a hissing sound similar to the sound a garden hose makes when it has a leak.
  • Water Accumulation - Unless you have a water leak, a noticeable puddle of water can indicate a freon leak. What happens is when there is not enough freon, the coils can not pull in enough warm air into the coils. The lack of warmth causes the coils to freeze which then causes condensation; causing a drip and puddle.

How Refrigerant Leaks Are Detected

A properly functioning air conditioner should not require a freon recharge as the gas is consistently cycling throughout your system and never actually burns out. Because of this, any issues related to inconsistent temperatures or warm air will often be attributed to an AC refrigerant leak.

If you have noticed any of the warning signs above, you may have a refrigerant leak. In order to positively determine whether or not you have a freon leak, the best course of action is to contact a professional. Our professional HVAC technicians can do one of three tests to determine what the problem is.

Detection Methods

  • Detection by Nitrogen - The first test is done by emptying all of the freon from the system. The technician will then push nitrogen through the system. As nitrogen is at a higher pressure than freon, you will be able to hear any air escaping from a hole or crack.
  • Detection by Electronics - An electronic leak detector can pinpoint the exact location of a refrigerant leak, allowing our technicians to make precise repairs.
  • Detection by Dye - Fluorescent dye is added to the refrigerant system and traced under ultraviolet light to identify leak locations that may be difficult to spot otherwise.

Frequently Asked Questions about AC Refrigerant Leak Repair in Portland, OR

Common signs of a refrigerant leak include warm air blowing from your vents despite the thermostat being set to cool, noticeably higher energy bills, a hissing sound coming from your AC unit, and water puddles forming around your indoor or outdoor unit. However, a professional diagnosis is the only way to confirm a refrigerant leak. Our technicians can perform detection tests to pinpoint the exact issue.
Yes, refrigerant leaks can pose health risks. Inhaling leaking refrigerant gas or fluid can cause refrigerant poisoning, which may result in symptoms like dizziness, headaches, and difficulty breathing. Additionally, refrigerant is an environmental hazard that requires proper handling. If you suspect a leak, avoid prolonged exposure to the area and contact a professional technician immediately.
Your AC system is designed to be closed and self-contained, so refrigerant should never need replacement under normal circumstances. If your system requires a recharge, it indicates a leak somewhere in the system. Simply adding more refrigerant without repairing the leak is a temporary fix that will not solve the underlying problem.
The time required depends on the severity and location of the leak. Simple leaks at connection points may be repaired in one service visit, while more complex leaks involving coil damage may require additional time. Our technicians will assess the situation and provide you with a timeline before beginning the repair work.
Yes, regular AC maintenance significantly reduces the risk of refrigerant leaks. Routine inspections allow technicians to identify corrosion, connection issues, and potential damage before they develop into leaks. Annual tune-ups help keep your system in optimal condition and can extend the life of your air conditioner.
