Highlights
  • Refrigerant price increases by about $50 per additional 0.5 tons.

  • Refrigerant for AC units built before 2010 or after 2025 costs more than average.

  • If the leak is in your wall, also budget for drywall repair at $1.50 and $3 per square foot.

  • By law, you can’t tackle this project yourself.

  • In addition to a recharge, you’ll also pay about $100 for safe freon recovery and removal.

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. 

AC Recharge Cost Factors

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:

From one homeowner to another

Manny was very trustworthy and professional. He gave me a very fair price. Within 24 hours he had done his inspection and given me an estimate. It's the first time I talked to an HVAC company that didn't make me feel like I was getting overcharged. One of the other companies I spoke to was trying to charge 6 times the cost. He took lots of pictures and video and explained step by step what was done wrong by the other contractors and what he would need to do to fix it. He was able to do the work the day after I accepted the estimate. He completed all the work in one day. I am confident and very relieved to say that my HVAC system is set up properly.

Size

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 TonsAverage 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

R-410A$12–$25ACs built between 2010 and 2025

Labor

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

Prep

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:

Location

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. 

Post-Construction Cleanup

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

DIY AC Recharge vs. Hiring a Pro

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. 

Ways You Can Save Money During an AC Recharge

4 benefits of year-round HVAC maintenance, including lower energy bills and better air quality

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.

Frequently Asked Questions

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
