How long will refrigerant (aka Freon) last in my air conditioning unit? The answer is that it should last forever unless you have a leaking system. Contrary to popular belief, units shouldn’t need to be recharged every year. Many customers call our office because their AC system isn’t working as it should, or isn’t working at all.

We sometimes find out the problem is related to a low refrigerant charge. This means you have a leaking system. At that point, we would lay out the options. The best option is to perform a leak search and devise a solution. However, we have many clients who just want to “top off” the system. The problem with topping off a system is that it will leak back out.

No one can tell you how long the refrigerant you’re purchasing will last. It’s not a repair; it’s a simple band-aid. “How long will it last?” is a question that simply can’t be answered with any accuracy.

Imagine having a nail in your tire. The tire leaks out enough air that you need to fill it in order to drive the car. Do you know how long to air pressure will last? It could last one hour, maybe a day, or even a week. The one thing you know is that it will leak out again unless you get it repaired.

We’re happy to “top off” refrigerant for our customers (within reason), but the technician will explain the risks. You might be throwing away money to have cooling for a week. Leaking systems cost more money to operate as well. They aren’t dependable and cost you more money! As soon as the unit is topped out, it begins slowly leaking.

When your unit doesn’t have a full refrigerant charge, it will use more electricity. It’s also damaging your compressor in the process.
