Steps

Confirm the existing pump's motor size (Total Horsepower) and pump type (single-speed, dual-speed, or variable-speed) before selecting a replacement
Check DOE's Energy Conservation Standards for Dedicated-Purpose Pool Pump Motors compliance dates: standards for motors with Total Horsepower (THP) of 1.15 or greater took effect September 29, 2025; standards for 0.5-1.15 THP motors take effect September 28, 2027 — verify current dates on energy.gov/the Federal Register since compliance timelines can be revised
Select a replacement pump/motor that meets the applicable DOE standard for its horsepower class as of the current date, not just whichever pump is cheapest or in stock
Size the variable-speed pump to the pool's actual hydraulic needs (turnover rate, filter/heater flow requirements) rather than swapping horsepower 1:1 with the old single-speed pump
Program speed/schedule settings to run at lower RPM for extended daily filtration and ramp up only for functions needing higher flow (vacuuming, heater operation, spa jets)
Verify any manufacturer or utility rebate program requirements (submittal paperwork, proof of installation) before completing the swap if the customer intends to claim one

Known gotchas

DOE's phase-in has two separate effective dates by horsepower class (2025 and 2027) — check which THP band applies rather than assuming the rule is uniformly in or out of effect
This is a federal manufacturing/sale standard, not a mandate to immediately replace an already-installed non-compliant pump — clarify this distinction with the customer to avoid overstating urgency
DOE appliance-standard compliance dates have shifted before via rulemaking delays or litigation — reverify the current effective date on energy.gov rather than relying on an older article

Scope an elevator modernization from a single-speed or older AC/DC drive to a VVVF (variable-voltage, variable-frequency) drive, including when machine-room-less (MRL) retrofit is feasible
