Existing equipment can remain in use
EPA says homeowners do not have to replace existing R-22 equipment because of the phaseout. Reclaimed, recycled or previously produced supplies can service it.
Ask the provider to confirm the refrigerant and fault before comparing costs. A label is not a diagnosis and does not tell you whether a repair is worthwhile.
Be careful with substitute claims
EPA states that there are no drop-in replacements for R-22. A retrofit needs an acceptable alternative and equipment changes, with performance implications explained.
R-22a and similarly named propane-based products are not R-22. Do not accept a substitute because the name sounds familiar.
Compare complete options
A repair quote should explain leak work, refrigerant and warranty. A replacement quote should explain the full installation. Ask what each addresses and what costs are excluded. The lowest initial price is not always the lowest total cost.
Keep three different decisions apart
Continuing to use a working R-22 unit, repairing a fault in that unit and converting it to another refrigerant are different decisions. The phaseout does not settle all three at once. A technician should explain which option is being proposed and why it fits the equipment.
If a retrofit is offered, ask for the component changes, the alternative refrigerant and the effect on performance to be explained. Do not accept "same thing, different name" as a compatibility explanation. EPA says the alternative must be acceptable for the application, and there are no universal drop-in replacements.
Compare scope rather than age alone
An old nameplate can raise sensible questions about repair economics, but it cannot identify the fault. Ask where refrigerant was lost, what component needs attention and whether the quoted repair addresses the cause. Then compare that with a complete replacement proposal if one is appropriate.
Avoid comparing only refrigerant price with the price of a new unit. The repair estimate needs labor and leak work; the replacement estimate needs the actual installation scope and warranty. Confirm what is included and what still requires a separate decision before authorizing either path.
