❄️ Capital Planning for the R-22 Phase-Out: Auditing Your Legacy Equipment Portfolio

R-22 (HCFC-22) was phased out of US production and import on January 1, 2020 under the Clean Air Act. The refrigerant that was once the standard for residential and commercial HVAC is now available only from reclaimed or stockpiled sources — and prices have climbed accordingly.

For property managers and HVAC companies servicing older portfolios, this is a capital planning problem as much as a service one. The question is not just whether a unit needs a recharge — it is whether that recharge still makes financial sense, and whether ownership understands the legacy equipment exposure across the entire portfolio.

Building Your R-22 Equipment List

The first step is knowing what you have. In Equipment Tracker Pro, every equipment record has a Refrigerant field. If you've scanned nameplates with the AI scanner, this field is likely already populated. If not, you can filter your equipment list by refrigerant type to see what's been logged and what still needs to be added.

Any unit manufactured before roughly 2010 is a candidate for R-22. From January 1, 2010 the EPA banned the manufacture and import of new equipment pre-charged with R-22 — it never mandated R-410A specifically — and dry-charge condensers that shipped empty kept selling after that date and got charged with R-22 in the field, so the year on the plate is a hint rather than proof. If you're unsure, the nameplate refrigerant field will tell you — or a quick model number lookup will confirm.

Building a Replacement Forecast Ownership Will Approve

Equipment Tracker Pro's Pro Reports include a Refrigerant Inventory report that groups every unit by refrigerant type, flags the phased-out gases, and lists each unit with its building and location — exportable as a PDF. Filter the portfolio by gas type and you have every R-22 unit and where it sits in one document; age, BTU capacity and service history stay on the individual equipment records, and the fleet's age comes out of the Age / Replacement report.

The install date and manufacture date fields give you the age of each unit. Combined with the refrigerant service history — how many recharges, what each one cost, and the leak rate calculated automatically in the service log — you have the data to build a print-ready Equipment Age & Replacement Forecast that justifies capital expenditure to ownership in numbers they can follow. When a 19-year-old R-22 RTU has been recharged three times in two seasons at current reclaimed refrigerant prices, the replacement math makes itself.

Watch the threshold that applies to these units, because it is not the one in most of the 2026 coverage. The 15-pound line introduced by the AIM Act rule at 40 CFR 84.106 applies to HFC refrigerants. R-22 is an HCFC, so it stays under the Section 608 rules at 40 CFR Part 82, where mandatory leak repair starts at a full charge of 50 pounds or more. The trigger rates are the same under both: leak rates above 10% for comfort cooling, 20% for commercial refrigeration or 30% for industrial process refrigeration start a 30-day repair clock. In practice that means a legacy R-22 rooftop unit can leak more freely before federal repair rules bite than the R-410A unit you would replace it with, which is an argument for replacement rather than against it.

When was R-22 officially phased out in the US?

R-22 production and import in the United States was completely phased out on January 1, 2020. Servicing R-22 equipment now relies entirely on reclaimed or stockpiled gas.

Which units in my portfolio are likely to use R-22?

Any unit manufactured before 2010 is a candidate for R-22. The EPA banned manufacture and import of new R-22 pre-charged equipment from January 1, 2010, but it never mandated R-410A specifically, and dry-charge units that shipped empty were still sold and field-charged with R-22 after that date — so check the refrigerant on the nameplate rather than trusting the year.

How can I identify R-22 units across my buildings?

You can filter your equipment database by refrigerant type in the app or run a Refrigerant Inventory Summary report to group all assets by their refrigerant charge specification.

What EPA Section 608 rules apply to R-22 equipment?

R-22 is an ozone-depleting refrigerant, so it stays under the Section 608 rules at 40 CFR Part 82 rather than the AIM Act rule at 40 CFR 84.106. Mandatory leak repair applies from a full charge of 50 pounds or more, with a 30-day repair clock once the annualized leak rate exceeds 10% for comfort cooling, 20% for commercial refrigeration or 30% for industrial process refrigeration. The 15-pound threshold that took effect on January 1, 2026 applies to HFC systems such as R-410A, not to R-22.

How do I build a replacement forecast for legacy units?

Run the Age / Replacement report, which lists every unit with its age and flags anything 15 years or older as a replacement candidate, then pull the recharge dates and costs out of each unit's service log to show what keeping the old R-22 systems running actually costs.
