re: What's the going rate for A/C freon

$100 per pound is the going rate for R-22 refrigerant (R-22) but I would think an eight year old unit would be using R410A refrigerant - 410A should be much cheaper than R-22 but I don’t know the going rate.


There have been some new old stock R22 equipment installed by independent operators in recent years, but usually it is just the compressor, when the home owner is trying to save some money by not replacing the entire system.

re: What's the going rate for A/C freon
This sounds about right....

Mine had a leak in it, 15 year old unit. He fixed the leak and measured the Freon level

It was dead empty. Cost me about $700 last year .

Just cut it on the first time this year and it’s blowing great.

I’ve heard that.

I required a pound of R-22 3 years ago and it was $100 per lb then, but chatting with a tech from the same company this past Dec when he was doing winter maintenance service on my unit he told me their company was still charging $100 per lb for R-22 but he didn’t know for how much longer.

re: What's the going rate for A/C freon
If you don’t find and fix the leak, you’re just throwing money away ! Plus if he is a legitimate tech.’ He is not suppose to top off a unit with R 22 if it has a leak especially that large ! Make sure you know the refrigerant type. As stated earlier there are some drop-in refrigerants that can be used. Regardless you need to find and fix your leak ! Maybe time to replace the entire unit !

re: What's the going rate for A/C freon
R-22 shouldn't be over 80 dollars a pound the price is actually cheaper now than it was 2 years ago. The part is a expansion valve not joint it is a metering device in your evaporator coil to allow the correct amount of coolant to pass through the system. They are different for each type of refrigerant but he will need to flush the system to remove the oil residue from the system if he just changes the expansion valve and not the coil.

R22? Replace the entire unit. Most of the new AC's out there have ten year warranties.

Someone I know leaked out freon. Spent over $800 of freon and a plug. The tech who installed it said the plug only lasts so long, so if this happens again just replace it. Less than a year later it happened. They got a new unit which is much more efficient and has Puron.

Get a variable speed compressor/blower. Game changer. I love mine.

This is what I did. The unit leaked down a couple of times in a summer. Fresno was too expensive to let it lea and it was going to cost me $1500 to replace the coil that was leaking with no guarantee that would stop the leak.

I chose to replace the unit with a much more efficient one. Utility beel savings coupled with some incentives from my power and gas utilities made the decision to replace much more palatable.

re: What's the going rate for A/C freon
It's always nice to be able to upgrade to the latest technology;however, it's not always financially feasible-only you can decide on that.
The expansion "valve" is a device that is mounted immediately prior to the evaporator core/coil. It turns hi pressure liquid freon to a low pressure gas. This is the point in the system where the actual "cooling" takes place.This causes the entire evaporator to turn cold. The blower blows air across the evaporator and out of the ventilation ducts as cold air. Replacing the expansion valve is typically a good idea when doing a repair on the a/c system. Good luck.

All you gotta do is change the piston. Y’all need to email me and let me save you major cash.

UPDATE - A/C guy just called and said I need to replace the outside unit and keep the coil & replace the expansion joint. Unit is a 5 ton Trane. He's supposed to call tomorrow with


First off it's not a expansion joint is called a txv which is thermal expansion valve. It's like a carburetor that meters the freon. If the txv is not working it properly it will have the same symptoms of a unit needing freon but the freon is still there. You may just need the txv head replaced instead of the whole part.If your unit is totally out of freon then it's not the txv and it's most likely a indoor coil leaking. Do NOT add freon with having a leak check done first otherwise you're wasting money .

After rereading your info it sounds like your leak is on the outside unit and he wants to replace it and replace the indoor expansion valve. Unless you have a R22 unit and going to R410 freon you shouldn't need to replace the indoor expansion valve.

Before replacing get a 2nd opinion.

It's actually a EPA violation to repair a R22 unit using new R22. Get a new unit because that old R22 unit has list most of it's efficiency.

Eta a jug of R22 runs over $500. Unless your using the replacement for R22.

It's also impossible for true R22 to be cheaper now because it's no longer manufactured. R22 replacement freon is cheaper but not real R22. Regardless repairing a old R22 system is a total waste of money.

No, the only time you replace a txv is when it is not metering.

re: What's the going rate for A/C freon
If people really want to be efficient rip out your central hvac and ductwork and install mini-split heat pumps. Extremely efficient and much more healthy then ductwork provided air. These units can have SEER ratings of 26 and higher. America is basically the only civilized county still using central hvac and ductwork.

re: What's the going rate for A/C freon
what fefrigerant?

R-22, R-410a?

What's the expansion joint and does it sound like bs?





Expansion "valve" is just an orifice in the piping just before the evaporator coil (indoor unit coil). the rapid expansion of a compressed gas is endothermic process. if you have touched your propane take when boiling crawfish the tank feels cold.

sounds like the compressor went out or has a leak. IMO, better to replace the outdoor unit (condensing unit)

i bought a 4 ton condenser a few years ago an paid one of our techs on the side a couple of hundred bucks to pull vacuum, braze the copper, and wire the unit up. cost me around $1500 all together.

If it's out of freon the only way the compressor is involved if it blew out the terminals. It's most likely the condenser coil leaking.

If you want a efficient unit do not piecemeal it. People ignore the hvac as long as it's working but studies show hvac usages cost up to 49% of your electric bill.

The txv is actually mounted as part of the coil. If anyone ever needs a txv replaced and the unit is under a factory part warranty they should go ahead and replace the whole coil... doesn't take as long and cheaper labor wise.
Most txv , when failed, just need the heads replaced.

Note A expansion valve is NOT just for a indoor coil as most units have a expansion valve on the outdoor, condenser, coil.

They were installing R22 units 8 years ago?

Surprising. R22 has been out of cars for decades.
