How to find a leak in a heat pump?
The most precise method for locating Freon leaks is for the technician to install a liquid tracer into the air conditioning or heat pump system, and allow it to circulate about two weeks. A small amount of fluorescent dye is added to an air conditioning system or heat pump and allowed to circulate. The dye escapes with the system’s refrigerant or fluid and remains at all leak sites. When the system is scanned with an ultraviolet inspection lamp, the dye fluoresces brilliantly to pinpoint the exact source of every leak. Proven to find multiple and intermittent leaks undetectable by any other method. Even leaks smaller than 1/8 ounce per year.
