It is a trade heuristic, not an authority position. The rule — multiply the equipment age in years by the quoted repair cost, and replace if the result exceeds $5,000 — appears on a large number of contractor and manufacturer marketing pages and in no publication from the DOE, the EPA, ENERGY STAR or ASHRAE. This builder still models it, because contractors use it and clients ask about it by name, but it is labelled as a heuristic on screen and on every export so nobody mistakes it for regulation. Its weakness runs deeper than provenance: a fixed dollar threshold set against costs from an earlier decade drifts toward recommending replacement every year equipment prices rise, which means the same repair on the same unit changes verdict over time without anything about the equipment changing.

They are different test procedures, not a rebadge. SEER comes from DOE appendix M; SEER2 comes from appendix M1, which became the basis for compliance on 1 January 2023. The substantive change is that M1 tests the same equipment against 0.50 inches of water column external static pressure instead of 0.10 — a fivefold increase, intended to reflect the duct systems equipment is genuinely installed on rather than a laboratory bench. Because the unit is doing more work to move the air, the rating comes out lower. AHRI publishes approximate conversion factors of about 0.95 for SEER to SEER2 and 0.85 for HSPF to HSPF2, and this builder applies them automatically when you tell it the nameplate is a pre-2023 rating. They are approximations: two units with identical SEER can land on different SEER2 numbers, and only a re-test under appendix M1 gives the exact figure.

No. R-410A is still produced, and an installed R-410A system remains legal to operate and legal to charge. What changed is new equipment: the EPA Technology Transitions rule, made under the AIM Act, requires residential and light commercial air conditioning and heat pump systems manufactured or imported from 1 January 2025 to use a refrigerant below 700 GWP, so replacement equipment now comes charged with R-454B (GWP 466) or R-32 (GWP 675) rather than R-410A (GWP 2,088). That is a fact about what you can buy, not about whether your existing system can be repaired. Anyone telling you an R-410A system is about to become unserviceable is describing R-22, not R-410A — and this report keeps the two apart, treating R-22 as a genuine replacement indicator and R-410A as a note.

For split-system air conditioners it depends on region and capacity, which is why quoting one national number is wrong. Under 10 CFR 430.32(c), for products manufactured on or after 1 January 2023: 13.4 SEER2 in the North at all capacities; 14.3 SEER2 in the Southeast and Southwest below 45,000 Btu/h, and 13.8 SEER2 at 45,000 Btu/h and above. Heat pumps are national at 14.3 SEER2 and 7.5 HSPF2, and single-package units are national at 13.4 SEER2 with 6.7 HSPF2 for package heat pumps. Southeast means AL AR DE FL GA HI KY LA MD MS NC OK SC TN TX VA plus DC, Puerto Rico and the territories; Southwest is AZ CA NM NV, and it adds EER2 requirements on top of the SEER2 floors. Everything else is North.

Not on age alone, and this report deliberately will not say so. Fifteen years is the ASHRAE median service life for a residential split-system air conditioner or air-to-air heat pump, and median means exactly half of the surveyed population had been replaced by that age — the other half were still running. A gas- or oil-fired furnace has a median of 18 years, a fan coil 20, a steel fire-tube boiler 25, ductwork 30, and a cast iron hot water boiler 35. Age is one of seven indicators here; on its own it produces a "monitor" verdict, not a "replace" one. It takes three indicators pointing the same way — for instance an old unit with a failed component and a repair quote that is half the cost of replacement — before this report recommends replacement.

Annual energy for a given end use is inversely proportional to the seasonal efficiency metric, so replacing a unit rated R with one meeting the current federal minimum M reduces that energy by 1 − R/M. A unit whose 10 SEER nameplate converts to 9.5 SEER2, replaced with a 14.3 SEER2 minimum-efficiency system, uses about 34% less cooling energy. A 65% AFUE furnace replaced at the 80% AFUE minimum uses about 19% less fuel for heating. Two honest caveats appear on the report itself: this is the energy for that end use, not a reduction in the whole utility bill, and it is a nameplate-to-nameplate comparison that assumes correct installation, correct charge and adequate airflow — which is exactly why the report also grades static pressure, charge and duct condition.

An inspection or maintenance checklist is a pass/fail task list: it records what was done and what was found. This is an assessment, and it ends in a decision. It grades condition against observable criteria, estimates remaining service life against published data, quantifies the efficiency gap against the current federal standard, weighs the repair quote against the replacement cost, and prints a repair, monitor or replace recommendation with all seven indicators shown — including the ones that did not fire. If you need a record of a maintenance visit, use the maintenance checklist. If a client has asked whether to fix it or replace it, this is the document that answers them in writing.

No, and every export says so. It is a professional assessment of an existing system on the date shown, based on what was observable and measurable at the time. Federal standards are cited to explain what the installed rating is being compared against, not to certify anything, and the efficiency minimums quoted apply to equipment manufacture rather than to what may remain lawfully installed. Nothing here warrants future performance — a system inside its median service life with every check graded serviceable can still fail the following week.
