Check whether the appliance is covered, calculate the leak rate, compare it with the correct threshold, and keep the records needed for review.
HVACAudit by Subpart helps owners manage Subpart C refrigerant records for covered circuits. Subpart provides accounts, service links, reports, billing, and compliance history.
48-hour service linksOwners send a temporary link to the technician.
No technician accountThe technician can complete the service record without logging in.
Certification numberCertification number and service notes are captured with the record.
Owner historyCompleted records stay connected to the owner’s site, asset, and covered circuit.
Applicability
When 40 CFR 84.106 may apply.
The rule applies beginning January 1, 2026 to certain refrigerant-containing appliances with a full charge of 15 pounds or more, subject to refrigerant scope and exclusions.
GWP greater than 53
For substitutes, confirm the GWP basis.
Excluded equipment
Residential and light commercial air conditioning and heat pump subsector appliances are excluded.
Thresholds
Leak-rate thresholds by category.
Use the threshold that matches the covered appliance category.
| Appliance category | Threshold | Use |
|---|---|---|
| Comfort cooling, refrigerated transport, and other covered appliances | 10% | Use for covered appliances outside the commercial refrigeration and industrial process refrigeration categories. |
| Commercial refrigeration appliances | 20% | Use for covered commercial refrigeration appliances. |
| Industrial process refrigeration appliances | 30% | Use for covered industrial process refrigeration appliances. |
Timing
Repair timing and follow-up.
When the calculated leak rate exceeds the applicable threshold, the follow-up record tracks repair timing, verification tests, inspections, retrofit or retirement decisions, records, and reporting items.
Repair timing
The general repair window is 30 days, or 120 days if an industrial process shutdown is required.
Verification
For threshold-exceeding repair records, keep initial and follow-up verification-test results with the repair history.
Records
Keep records long enough to support later review.
FAQ
Common questions
Short answers for coverage, service links, calculation, and account history.
What are the leak-rate thresholds?
Commercial refrigeration is 20%, industrial process refrigeration is 30%, and comfort cooling, refrigerated transport, and other covered appliances are 10%.
What if the threshold is exceeded?
After a threshold exceedance, the follow-up path depends on the record facts: repair, verification testing, inspection, reporting, retrofit, or retirement.
Is this legal advice?
No. Confirm the current rule text and facts for the appliance, refrigerant, and service event.
