The average cost to recharge the Freon levels in an air conditioner unit ranges between $200 and $600. This number can vary, depending on the city you live in, the HVAC provider you choose, and the refrigerant levels in your air conditioner.
Depending on the type and amount you need, it's likely the cheapest serviceable part of your AC unit. The reason it costs so much is that you need a qualified person to put it in the unit, which takes time and labor, both of which are the expensive parts of the service bill.
If you need refrigerant for your air conditioner, you'll need to contact a professional heating and cooling technician. Under EPA regulations, only a certified professional can recharge your home's HVAC system.
Residential Air Conditioner Freon Refill Cost
Most homeowners will pay in the range of $200 to $400 for a refill, depending on the type and size of their HVAC unit. If you own a larger r22 unit, you may have to spend $600 or more. To break this down for you, a 25lbs unit of r410A costs anything between $100 and $175.
If you put the newer freon in right away, your unit will rupture due to the force. However, you can convert your AC unit to handle R410A. You'll need to replace the compressor, condenser, evaporator, and likely the refrigerant tubing. If you replace all of this, your old unit will work fine with the new freon.
Generally speaking, a properly maintained air conditioner can expect its refrigerant to last around 10-15 years or longer—depending on usage frequency and environmental wear and tear. To ensure your refrigerant lasts as long as possible, regular maintenance is key.
According to PG&E, most central air conditioning systems use two to four pounds of refrigerant per ton of cooling capacity. A three-ton air conditioner would typically have six to 12 pounds of refrigerant for a proper charge.
While the refrigerant in your vehicle can escape even without a leak, it's often not enough to cause significant issues unless you've failed to top up the refrigerant for years. When the lack of refrigerant becomes significant though, it can cause a number of problems, including an overheating driver in the summer sun.
First, check your filters and coils for dirt and debris that may be impeding airflow. Once you've cleaned the filters and coils, run the air conditioner with just the fan so that the ice accumulation can melt off. If the AC still doesn't blow cold air, it could be that refrigerant levels are too low.
Adding Freon to an AC unit is not a typical DIY project. It requires working with a dangerous chemical, a pressurized tank, and intricate equipment. Any part of the process going wrong can permanently damage your AC unit or cause injury to yourself. Contact a local HVAC professional for this type of service.
An AC leak will lead to warmer air from your vents over time. In most cases this can be fixed with a proven stop leak additive to seal up any leaks. When it's time for an AC recharge, turn to AutoZone.
How Much Does a Freon Refill Cost? Typically, a Freon refill costs anywhere from $100-$350. The amount varies due to several factors, including the size and type of your air conditioning system. The coolant will cost around $75-$175.
The amount of Freon your AC system requires depends on several factors, including the size of your home, the type of system, and its specific design. On average, most residential air conditioning systems need between 2 to 4 pounds of refrigerant per ton of cooling capacity.
A professional AC recharge typically ranges from $150 to $300.
You need to be aware that if your AC unit uses the CFC type of refrigerant, you will need a licensed AC technician to recharge the system in the United States. It is against the law in the U.S. for anyone not licensed to buy or use ozone-depleting CFC or HCFC refrigerants.
The Environmental Protection Agency (EPA) began the phase out of Freon in 1992 when it ordered the ban that took effect in 2020. Because of the long phase-in starting in 2010, new air conditioning, heat pumps, and refrigeration systems stopped using Freon, which is also known as HCFC-22 and R-22.
Most ACs nowadays come shipped from the manufacturer with the exact amount of refrigerant that it will need for the duration of its life. So, unlike a car, your AC won't ever need to “fill up” on refrigerant unless something goes wrong with the system.
Freon is no longer used in new AC units.
So, what happens if you do just add refrigerant to a leaking AC system, or don't get it fixed once the leak is reported? The EPA will fine you. There is no way to sugarcoat this. The fine can be as high as $37,500 per day.
Incompatibility Issues: It's essential to replace Freon with an appropriate refrigerant. Choosing the wrong one will damage system components. Avoid Leaks: Minor mistakes made when replacing Freon can cause leaks, impair system cooling efficiency, or result in a complete system failure.
