For a split heat pump, confirm the proposed indoor and outdoor equipment together. An outdoor model number alone may not identify the system combination associated with an efficiency rating. Ask the contractor to provide the matching information that supports the performance claim in the quote.
AHRI explains that its performance certification for a split system depends on properly matched indoor and outdoor units. Certification information is useful evidence about rated performance; it is not a substitute for correct installation or project-specific sizing.
List the outdoor unit, indoor coil or air handler, any relevant furnace configuration and controls identified by the contractor. For a multi-split system, ask how the proposed indoor units are represented in the supporting documentation.
Keep the full model identifiers, including relevant suffixes. A shortened brand-series name may be insufficient to distinguish one combination from another.
Where an AHRI-certified combination is being represented, request the certified reference or applicable directory record. Ask the contractor to explain how the listed equipment corresponds to the proposal. If different documentation applies, request that explanation rather than assuming every product arrangement appears in the same format.
Do not treat a directory match as proof of rebate eligibility. A program can impose its own conditions, and the administrator's current requirements need checking separately.
These questions make the proposal traceable without asking the homeowner to engineer the system. The contractor should be able to explain the relationship between the quote and its supporting information.
If equipment changes, request an updated combination record before accepting the substitution. Similar capacity or appearance does not establish identical rated performance. Ask whether controls, installation requirements, warranty or program documentation also change.
Keep the accepted revision with the original quote so the reason for the change is clear. Do not rely on a verbal “same thing” explanation where the project depends on specific performance or eligibility.
At handover, compare the installed model schedule with the final invoice and accepted proposal. Use label photographs supplied by the installer or safely visible identifiers; do not open cabinets or climb to inspect equipment.
If the records disagree, ask for clarification and corrected documentation. A complete combination record supports future service and makes performance claims easier to understand. It does not guarantee the home's comfort by itself: sizing, distribution, controls and installation checks still matter.
