2021 Notice: Material Prices are Surging

Demand for HVAC services has grown over the past year. And, as a result, manufacturers are increasing materials prices. Prices have gone up 5% to 10% this year, and many parts of the country are experiencing long delivery times. If you're planning an HVAC project, we recommend starting as early as possible in the season, preparing for potential price fluctuations, and allowing extra time to order materials.

Residential Air Conditioner Freon Refill Cost

Freon costs an average of $150 for a Freon refill. Most people pay between $100 and $350 for a refill, depending on the size and type of your HVAC unit. Older large r22 units can reach $600 or more. A 25lb jug of r410a runs $75 to $175. Labor adds an average $70 per hour.

“Freon” is simply a brand name owned by DuPont chemicals. But it’s used as a generic term for any air conditioning coolant. Older systems used the r22 type of refrigerant, known for depleting the Earth’s ozone layer. As of 2020, it’s no longer legal to import or produce r22 in the United States. All systems installed after 2010 use the alternative r410a refrigerant.

How Much Does Freon Cost Per Pound for Central Air?

You’ll pay $75-$175 for a 25-pound canister of Freon. Most systems only need 6 to 15 pounds. Pricing also depends on the type your system uses:

  • The old-style refrigerant, r22, known for depletion of the ozone layer, is banned.
  • 2010: all new system installs use the new type, r410a.
  • 2020: r22 isn’t imported or manufactured.

To complicate things, older r22 systems can’t use r410a due to pressure differences. So, if you have an old r22 system, your next recharge will cost significantly more since you’re looking to either upgrade or replace your HVAC system.

What Does AC Refrigerant or r410a Freon Cost Per Pound?

The current HVAC standard coolant, r410a, costs about $3 to $8 per pound. All systems manufactured or installed after 2010 use r410a. The costs fluctuate depending on demand.

R22 Freon Cost Per Pound

As of 2020, you can no longer purchase r22 coolant. Until then, it’ll range from $20 to $50 per pound. As of the writing of this article, it’s almost impossible to get r22 Freon.

Home AC Recharge Cost

Recharging your home air conditioner runs $150 on average. However, since coolant only escapes with leaks or damage, this service is wrapped into other repairs, like a coil or line replacement.
