Car AC repair cost calculator

Work out what fixing a car's air conditioning will cost from the part, the labor, and the refrigerant. A recharge is a small bill; a compressor, condenser, or evaporator is the expensive end. And a recharge that leaks out in weeks means a leak to find first, which the calculator helps you weigh.

§ 01 Your numbers

Change anything. The answer updates as you type.

The failed part. A pressure switch or a valve is cheap; a condenser is mid; a compressor or evaporator is the expensive end. Zero if it is only a recharge.
Time to fit it. A recharge is quick; a compressor is a few hours; an evaporator behind the dashboard is most of a day.
The shop's hourly rate. AC work needs specialist recovery equipment.
Evacuating and refilling the system with refrigerant. Newer R-1234yf refrigerant is far more expensive than older R-134a, which alone can double a recharge.
Finding where the refrigerant is leaking, often with dye or an electronic detector. Worth paying before a recharge that will just leak out again.

$250 to $900 is a condenser or a mid-range part with a recharge. Confirm the leak is fixed, not just topped up.

What this assumes, and where it could be wrong

Every one of these is a place the number could be off. They are here because you should be able to check our working, not because we are hedging.

A RECHARGE THAT DOES NOT LAST IS A LEAK, NOT A REFILL.
Air conditioning is a sealed system, so if the refrigerant is low, it leaked out somewhere. Topping it up gets you cold air for a while, but it will leak out again, and paying for recharge after recharge is the expensive way to avoid the actual repair. If a recharge did not last a season, pay for the leak diagnosis and fix the leak, not just the symptom

The part is the swing, and the compressor is the top of it. A pressure switch or a valve is a cheap fix; a condenser is mid; a compressor, which is the pump at the heart of the system, or an evaporator buried behind the dashboard, is the expensive end in both part and labor. Which part failed decides whether this is a small bill or a large one.

New refrigerant is far more expensive than old, and it decides the recharge line. Cars since the mid-2010s use R-1234yf, which costs several times what the older R-134a does, so the same recharge on a newer car is much dearer. If the recharge line looks high, the refrigerant type is usually why.

An evaporator is the job to dread. It sits behind the dashboard, so replacing it means removing most of the dash, which is many hours of labor even though the part itself is not the priciest. If the quote is a big labor number on a modest part, it is probably the evaporator.

The defaults are ours and are a starting point. The part, the labor, and the refrigerant are yours, and the estimate turns on which part failed and whether your car uses the cheap or the expensive refrigerant.

Frequently asked questions

How much does car AC repair cost?
It ranges from a cheap recharge to a compressor replacement that runs into four figures. A recharge or a small sensor is a modest bill; a condenser is mid; a compressor or an evaporator is the expensive end because of the part, the labor, or both. The calculator above adds up your quote. Which part failed is what decides it.
Why is my car AC recharge so expensive?
Usually the refrigerant. Cars built since about 2015 use R-1234yf, which costs several times what the older R-134a does, so the same recharge on a newer car is much more expensive. If the recharge itself is the big line, the refrigerant type is almost always the reason, not the labor.
Why does my car AC keep needing a recharge?
Because it is leaking. The system is sealed, so low refrigerant means it escaped somewhere, and topping it up only buys time before it leaks out again. Paying for repeated recharges is more expensive than paying once for a leak diagnosis and the repair. If a recharge did not last, find the leak rather than refilling again.
Is replacing a car AC compressor worth it?
On a car you plan to keep, usually yes, because working air conditioning matters for comfort and resale, but it is the expensive repair. Weigh it against the car's value and age: on an old, high-mileage car worth little, a four-figure compressor job may not be worth it. The calculator shows the number so you can make that call.
