Collect both model numbers.
Ask for the indoor and outdoor models, plus any additional components required by the identified combination. Do not match a certificate using a general product-series name alone.
HVAC · Redmond, Washington
HVAC in Redmond, WA.
HVAC in Redmond should connect a claimed split-system rating to the actual indoor and outdoor equipment being supplied. Ask for the applicable AHRI reference or certificate and compare its model combination with the proposal.
Evergreen Home Pro helps you prepare that verification. Share the proposed equipment list and ask how any substitution or retained component is checked before installation.
Heating and cooling
Check the certified combination against the proposed models.
An AHRI certificate identifies a certified equipment combination. It is useful product information, while sizing, installation and site performance still need assessment; a certificate does not establish those outcomes by itself.
Locate the applicable reference.
Have the contractor provide the certified reference or certificate for the actual combination where applicable. Compare the listed models with what is quoted and delivered.
Recheck substitutions before accepting them.
Ask how a changed indoor or outdoor component affects the certified combination and proposal. Keep the final equipment information consistent in the handover records.
Before work begins
Confirm the separate city mechanical and electrical permits.
Redmond’s mechanical application states that a permit is required for mechanical equipment installation, alteration or replacement. Describe the actual system and associated work in the city process.
The city also publishes its own electrical application as a separate permit. Have the responsible installer confirm both applicable trade scopes instead of assuming a mechanical permit includes electrical approval.
