Your R22 Air Conditioner: Repair or Replace Guidelines (2024)

This is an update to one of our most popular and helpful blog posts. We’ve added advice for those of you who have an older R22 AC unit that uses the Freon refrigerant which is being phased out. Here’s the original: Repair or Replace An Air Conditioner: The Right Way to Decide.

If you’ve got an aging air conditioner, you may be breathing a sigh of relief when Labor Day rolls around. You made it through another summer with the old unit! But don’t talk too soon, fall can still get steamy in NYC and if your unit is not performing as it should be, you could still experience a breakdown during a brutal week of Indian summer weather. Then you’ll need to decide whether to repair or replace it.

If you’ve got an R22 air conditioner (one that uses the old R22 refrigerant that’s being phased out) that decision gets even more complicated. That’s because repairs for an R22 air conditioner are getting very expensive as the available supply of the refrigerant declines and the price rises. Also, there’s another option besides paying the price for R22 and fixing it, or buying a brand new system. There may be the possibility of converting (also called retrofitting) your old R22 air conditioner to use one of the new refrigerants.

To learn more about the impending phase out of R22 and what it means for your air conditioner, read this guide that lays out your options: R22 Refrigerant Phase Out: Do You Need to Replace Your AC?.

Your R22 Air Conditioner: Repair or Replace Guidelines (2)

Here’s the good news: fall is really the best time to take control of your air conditioning issues and decide if it makes sense to repair or replace your R22 air conditioner, or if retrofitting may be an option for you:

    • If you decide to replace, you’ll have more time to find the right system for your needs since the weather is cooling off and there’s less pressure to make a quick decision. Plus, if you replace commercial AC equipment now, you can write off the ENTIRE COST on your taxes! That makes a big expense much more manageable. Watch this video to learn more.

  • You may also have the opportunity to get a great price on “leftover” units.
  • If you decide to repair or convert your older R22 air conditioner to use a new refrigerant, it’s easier to get time and attention from the best HVAC service experts since they’re less booked up than in the summer.

Repair or replace your R22 air conditioner? It’s a tricky decision

So, how do you go about making that decision to repair or replace your older R22 air conditioner? How can you tell when a piece of equipment has outlived its useful life? Can you get your older unit to last another couple of years by fixing it? Or will you have to keep throwing money into it, especially as the price of R22 continues to skyrocket? Newer units are more energy efficient and can lower your electric bill, but can you manage the upfront cost?

The unfortunate truth is, there is no cut and dried answer. But you can make the best decision to repair, retrofit, or replace your R22 air conditioner when you know what factors to consider about your equipment and its history, and whom to trust for advice.

How to get advice you can trust

It’s no secret that some service providers will try to sell you a new system when your old one just needs a simple repair (you’ve probably seen the YouTube videos and TV news stories exposing fraudulent service providers!). Other providers that make their money on repeat service calls may encourage you to keep fixing a unit that’s become a money pit. So whose advice can you trust to help you decide whether to repair or replace your R22 air conditioner? Here are two tips for weeding out vendors who might steer you wrong:

NEVER DECIDE ON THE SPOT. Be wary of any service provider that insists you need to rush into a decision to purchase new equipment. Be even more wary if they have not offered an adequate explanation – or one that’s unintelligible to someone who’s not an HVAC expert. You should never decide to purchase expensive equipment on the spot, because it’s easy to make the wrong choice and spend more money than you need to. It’s your right to take the time you need to decide whether to retrofit, repair or replace your R22 air conditioner.

SEEK OUT AN UNBIASED SERVICE PROVIDER. Look for an HVAC company that does both new equipment installations and repair service. That way, you can be sure they have no vested interest in advising you one way or another about your R22 air conditioner. The advice you get will be based on what makes the most sense for your situation, not what’s in the best interest of the vendor.

The facts you need to make a good decision about your R22 air conditioner

Even with the best advice, you need to understand the facts of the situation to make the most informed decision about your R22 air conditioner. Here’s what to consider:

Hanging on to an R22 air conditioner until the bitter end (January 1, 2020 is when R22 can no longer be manufactured or imported in the U.S.) does pose some risks, especially for a business that relies on air conditioning. When you finally need to replace, how long will you have to wait for a new system because you’re in line with everyone else who is forced to replace their R22 air conditioner?

Some problems, even though they may seem serious, can actually be easy and relatively inexpensive to fix. Electrical issues often fall into this category. And if your system is making so much noise that you’re afraid it’s about to die, the news may not be as bad as you think. You may just need some maintenance or redesign work.

However, if the compressor has failed, especially on an older R22 air conditioner, it’s often time to replace. The compressor is the heart of the system, and the investment to fix it may not be worth the cost. That’s also true because many times compressor failure is caused by a secondary issue that won’t be discovered until after you replace it.

When it comes to issues that require adding refrigerant to the system (such as a refrigerant leak), the fix might be prohibitively expensive for an R22 air conditioner. In that case, it’s probably time to consider replacement or a retrofit. However, you should know that retrofits are not an option for every system. There are technical variables and you’ll need a system inspection to determine your options.

Most residential and light commercial air conditioning units are designed to last about 15 to 20 years under optimal conditions. However, if you have a rooftop or other outdoor unit in a large city like New York, it’s unlikely that your R22 air conditioner has experienced optimal conditions! If your R22 AC unit has been exposed to harsh pollution for more than 10 years, it may not be worth making a large investment in repairs at this point.

How the equipment has been cared for has a major impact on the lifespan of an air conditioning unit, and hence your decision to repair or replace your R22 air conditioner. Has it been regularly serviced and cleaned according to the manufacturer’s recommendations since it was installed? If so, then most parts may be in good shape even if the system is more than 10 years old, and the unit is less likely to keep failing.

Has your R22 air conditioner been running reliably lately? If this is the first time it’s had a service issue, and the parts are in good shape, it may be worth fixing. On the other hand, if it’s had a history of breakdowns and poor performance, even if you fix it you’re likely to keep experiencing problems.

Here’s another tip: if the occupancy and usage of your space have changed, your system’s capacity and ventilation may no longer be adequate or even properly designed. If this is the case, if you fix your old R22 air conditioner you can still be left with temperature variances and even air quality problems. If you are experiencing hot and cold spots, humidity issues, odors, and even reports of “sick building” symptoms from occupants, replacement is probably the way to go. Your contractor can then evaluate the usage, capacity and location of your unit and ventilation equipment, increasing the comfort levels in your space.

HVAC equipment sales literature promises that an efficient new air conditioner will save you money by reducing your electric bill. Can the savings really be worth the cost of a new air conditioner replacement? Especially if you have an R22 air conditioner that’s more than 10 years old, the cash you save each month can be substantial and can add up very quickly. To figure out how much you could save with a new, energy efficient system, check out these online resources:

Your R22 Air Conditioner: Repair or Replace Guidelines (3)

Your R22 Air Conditioner: Repair or Replace Guidelines (2024)


Can R-22 AC units be repaired? ›

You may just need some maintenance or redesign work. However, if the compressor has failed, especially on an older R22 air conditioner, it's often time to replace. The compressor is the heart of the system, and the investment to fix it may not be worth the cost.

What is an acceptable replacement for R-22? ›

R410A is the most common, but others include R134a, R407C and R407A. These refrigerants cool interior spaces just as effectively as R22 with no ozone depleting characteristics and relatively low Global Warming Potential (GWP).

How much does it cost to replace R-22 refrigerant? ›

R-22 refrigerant costs $125 on average, but can range from $50 to $250.

Can R-22 still be recharged? ›

If you have an older air conditioning system that is low on refrigerant, recharging it is not a simple process. Because there is no more production of R22 and it is illegal to import, you will need to speak with a professional about how to refill an R22 air conditioner.

How much does it cost to convert R-22 to R410A? ›

Converting an AC from R-22 to handle newer refrigerants is no longer common. The process is typically too expensive—between $2,000 to $4,600—which may not be worth it depending on the cost to install a new AC system.

What is the life expectancy of a R-22 system? ›

If your unit uses R-22, it's probably at least ten years old. The average lifespan for an air conditioner or heat pump is about 10-15 years, so it might be time to consider replacing your unit anyway. Older units generally have lower efficiency and a greater risk of breakdown.

What happens if you put R134a in a R-22 system? ›

No, the compressor will fail. These two refrigerants have very different properties. One of R22 and R134a is high pressure and the other is low pressure. They don't mix chemically and don't have the same boiling point, leading to inefficiencies and eventual compressor failure.

Can you replace R22 Freon with something else? ›

Freon MO99 is the gold standard for R-22 alternatives and was developed by the same scientists who engineered Freon R-22. The benefits of Freon MO99 include: Capacity — The ability of Freon MO99 to heat or cool a given space is closer to Freon R-22 than any other refrigerant on the market.

Can a R-22 system be converted to R410A? ›

You cannot just switch refrigerants because R410-A and R-22 have different chemical properties. R410-A operates at a higher pressure. If you put R410-A into an R-22 system, the parts will rupture due to the increased force. You can convert your current system to one that runs on R-410A, but the cost will be high.

Is there a direct replacement for R-22? ›

An R-22 Refrigerant Replacement for Direct Expansion Refrigeration. Freon™ MO29 (R-422D) refrigerant is a low-toxicity, non-ozone depleting hydrofluorocarbon (HFC) replacement for R-22.

Is there a drop-in replacement for R-22? ›

The information below will try to dispel some of these myths. Arkema recommends using Forane® 427A (R427A) - The EASY RETROFIT™ for your r-22 retrofit solution. When it comes to drop-ins, the truth is that there are none. The hope of “drop-in” refrigerants has become common over the years.

Does anyone buy R-22 refrigerant? ›

ComStar will buy back R22 from your system assuming you meet the following requirements: 1,000 lbs. minimum buyback volume. 99.5% Purity (ComStar will provide laboratory analysis)

Is it worth replacing an R-22 compressor? ›

Replacing an R-22 compressor or the outdoor unit (which contains the compressor) is a good, low cost way to get your A/C system running again without changing the indoor system (which contains the cooling coil, the blower and often is integrated with a gas furnace or other heating system).

Are R-22 coils still available? ›

As of January 1, 2020, production and import of R22 refrigerant will be illegal in the United States. Of course, continued use of your air conditioner (AC) or heat pump system using R22 refrigerant is allowed.

Can you put new freon in an old AC unit? ›

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.

Can an RV AC unit be repaired? ›

If the AC in your RV happens to break or stop working properly, a quick RV AC repair is in order right away. While there are some RV AC repairs that will require calling in a professional, some repairs can be completed by anybody with a toolbox and a little bit of know-how.

Can you recover R-22? ›

Recover Your R-22 Refrigerant Safely and Efficiently

Place your recovery cylinder on your charging scale . Connect your manifold and hoses to the system: red-liquid, blue-vapor, yellow-recovery machine (valves closed). Connect a second yellow hose from the recovery system to the recovery tank.

How long does R22 Freon last? ›

Freon (which is really just a particular brand of refrigerant) lasts forever. It's not like gas in car; it does not get “used up.” You see, your air conditioner's refrigerant system is a “closed/sealed system,” meaning that it does not allow refrigerant to escape in any way.
