You can expect to spend $300 for a pro to perform an AC recharge. Several factors will influence your total cost, including the type and size of your AC unit and the cost per pound of refrigerant.
The average cost of an AC recharge is $300. Typically, homeowners pay between $200 and $500, depending on several factors, including the AC type, size, and age, the cost of refrigerant, and more. If your AC unit isn’t performing well, it might be time for an AC recharge. Our guide will walk you through an average AC recharge cost.
You’ll need an AC recharge when an AC freon leak comes from your unit. Many air conditioning units use freon, a common refrigerant that circulates throughout your AC unit and provides cool air in your home.
However, when there is a freon leak, you’ll need a pro to diagnose the problem and refill the refrigerant. Your total AC recharge cost will depend on several factors: type, size, materials, labor, prep, location, age, and post-construction cleanup. Here’s what you can expect to pay for an AC recharge:
Type of AC Unit | Cost Range for AC Recharge |
---|---|
Window AC | $100–$200 |
Mini-split | $100–$300 |
Central AC | $150–$600 |
The size of your air conditioning unit is measured in tons—and the larger your unit, the more freon it will typically need. Your AC unit will need two to four pounds of refrigerant for each ton. Here’s what you can expect to pay for refrigerant, depending on the size of your AC unit:
AC Unit Size in Tons | Average Cost of Refrigerant |
---|---|
1 | $100–$350 |
1.5 | $100–$500 |
2 | $150–$700 |
2.5 | $200–$900 |
3 | $250–$1,200 |
4 | $350–$1,500 |
5 | $500–$1,800 |
Depending on the type of freon used during your AC recharge, you could pay anywhere from $12 to $80 or more per pound.
Type of Refrigerant | Average Cost per Pound | Use Case |
---|---|---|
R-22 | $50–$80 | ACs built before 2010 |
R-410A | $12–$25 | ACs built between 2010 and 2025 |
R-454B | $80 | ACs built 2025 or later |
An AC technician will charge between $50 and $150 per hour for labor. Although you can expect to pay $100 to $300 just for a pro to come out to find a leak, it depends on the complexity of the leak. For example, a pro may trace the leak back to your ceiling or walls if you have refrigerant lines running through your home. If that’s the case, you’ll need to factor in extra costs to open the wall and install drywall—which will run between $1.50 and $3 per square foot.
Sometimes, a freon leak is due to other issues with your air conditioning system. So, before a pro can perform an AC recharge, you may need to fix or repair these common issues:
Evaporator coil replacement: $600–$2,000
AC compressor replacement: $800–$2,300
Condenser coil replacement: $600–$2,400
New AC unit installation: $3,884–$7,938
Usually, homeowners living in rural areas pay less for AC services than those in metropolitan areas. However, because freon needs to be shipped, technicians living in rural environments may incur higher shipping and delivery fees—and will pass those additional costs on to the consumer.
Homeowners cannot legally remove freon from their homes, as it is an ozone-depleting substance. Instead, you’ll need your AC technician to responsibly recover the refrigerant from your property and dispose of it or remove the freon by draining the refrigerant lines. Here’s what you can expect to pay:
Freon recovery: $50–$150
Freon removal: $30–$100
While an AC recharge may appear to be an easy DIY task, it’s not as simple as it seems. Due to the EPA and strict environmental laws, you’ll need to hire an AC repair company near you. In fact, the EPA actually restricts homeowners from purchasing refrigerants. You must be licensed with a Section 608 technician certification to purchase freon.
Licensed and professional AC technicians know how to properly and legally work with refrigerant, refrigerant lines, and freon leaks. Additionally, pros have experience working directly with refrigerant, so they understand how to control the spread and adequately and safely dispose of freon.
Although you can’t change the cost of freon, there are ways you can save on AC recharge costs, including:
Call your insurance company or manufacturer’s warranty to see if AC recharge is covered under your current plan.
Check for AC rebates or tax credits.
Repair leaks when you notice your AC unit isn’t functioning correctly.
Get an annual AC tuneup.
Get at least three quotes from reputable AC repair companies.
Replace the filter on your AC unit to keep it running smoothly.
Keep all vents open and running to prevent blockages.

You may never need an AC recharge if there are no leaks. However, if your AC unit has a leak that cannot be patched appropriately, you’ll need an AC recharge every time the freon level drops low enough that it disrupts your system—this could be once every two to three years. It all depends on the size and frequency of the leak.
There are ways to detect a refrigerant leak with several different testing methods. However, most homeowners can figure out something’s wrong with their AC unit by noticing these common signs:
Ice forming on the evaporator coil
Water leaks near the AC unit
Frequent hissing sounds
Increased electric bills
Unit takes longer than usual to cool
Unit is blowing hot air
Several things might cause a coolant leak in your air conditioning unit, including:
Damage to the AC unit
Manufacturing error
General wear and tear
Thinned-out connectors and joints
Poor installation
Corrosion
Wearing away of the rubber seals or copper tubing
