Air ConditioningIs My AC Leaking Refrigerant?

A refrigerant leak is a fairly serious issue for an air conditioner or heat pump. Since refrigerant is so important for the heat transfer process, a refrigerant leak will usually have some visible signs. Make sure you’re aware of the signs since having a leak resolved promptly is a great way to protect your air conditioner or heat pump in Bremerton, WA from serious damage.

Signs of a refrigerant leak

  1. Ice on the system
  2. Short cycling
  3. Warm air

1. Ice on the system

If you have a heat pump, keep in mind that ice on the system is not necessarily a sign of a huge problem. Heat pumps may ice over during operation, and they have a defrost cycle because of this. But if the icing is more and more frequent, or if you have a central air conditioner, ice could be a sign of a refrigerant leak. If the evaporator coil is iced over, it could be due to a very dirty air filter. If there is ice on the coil and frost on the refrigerant lines, it likely means there’s a leak.

2. Short cycling

Does your air conditioner start, run very briefly, and then cycle back down again? If so, this is known as short cycling, and this can be a sign of a refrigerant leak. If there is not enough refrigerant in the system, it will work harder as it tries to cool your home. While it’s doing this, it may overheat and cycle off.

3. Warm air
