Leak repair cost depends on where the leak is and how long it takes to find, the type and amount of refrigerant, the parts replaced and the recovery, evacuation and recharge work. A small joint leak is a smaller job than a leaking coil. Topping off without repair is a poor use of money.
Refrigerant does not get used up, so any loss is a leak. The cost of finding and repairing it is usually less than the cost of repeatedly refilling a leaking system.
What sets the price
| Cost driver | Why it moves the price |
|---|---|
| Leak location | Accessible joints are simpler. Coils, buried lines and receivers are harder. |
| Search time | Slow leaks take longer to pinpoint. |
| Refrigerant type | Some are costlier and harder to get. |
| Amount | Larger charges cost more to recover and replace. |
| Parts | Drier, valves or a coil may need replacing. |
| Verification | Pressure testing and follow-up checks take time. |
What is usually included
A proper job includes locating the leak, recovering refrigerant, repairing, replacing the drier, pressure testing, evacuating, charging by weight and checking performance. Ask for the refrigerant amounts on the invoice.
Questions to ask before you agree
- What exactly failed, and how did you confirm it?
- Is the part new, used or rebuilt, and what warranty covers it?
- Does the quote include labor, refrigerant, disposal and taxes?
- What could change the price once work begins?
- What will prevent the same failure again?
- How long will the box be down?
Do not just top off
See can you top off a leaking system for why, and recovery, evacuation and recharge for the steps. Rules on leaks and handling are covered on the leak rules page.
Old refrigerant
If your system uses a refrigerant being phased down, ask how that affects cost and options. See R-404A and R-22.

We do not print dollar figures on this page because real prices depend on the box, the part, the refrigerant and the day. Ask for a written quote before work starts.
Two examples of why leak jobs differ
A visible oil stain at a flare fitting points a technician straight to a loose joint, so the repair and verification are quick. A slow leak in an evaporator coil above a freezer ceiling may need pressure testing, dye or repeated electronic checks, followed by a coil repair or replacement. The refrigerant amount is similar, but the search and the repair are not. Ask what method the technician will use to find the leak and how they will prove it is fixed.
Early warning signs
Catching these early usually means a smaller bill:
- Bubbles in the sight glass.
- Oil stains at fittings.
- Long run times with a warm box.
- Ice on the suction line.
- Repeated top-offs.
Write down when you notice them and how often. Notes like these shorten diagnosis, and shorter diagnosis means less labor on the invoice.
Questions about this topic
Why is the leak hard to find?
Small leaks may only show under pressure or at certain temperatures.
Can dye help?
Sometimes. The technician decides the best method.
Will it leak again?
Not if the cause is fixed and the repair is verified.
