Measure the proposed location
Show the equipment footprint and its relationship to front, side and rear property lines. Have the actual boundaries confirmed where they are uncertain.
HVAC · Black Diamond, Washington
HVAC in Black Diamond moves more smoothly when the equipment proposal stays consistent through every review. The model, dimensions and location shown to the city should match the system you intend to install.
Evergreen Home Pro helps you gather comfort needs and the supporting equipment documents. If the property is in an HOA, bring the application requirements into the discussion while the placement and product choices are still flexible.

Heating and cooling
Keep a location sketch with the exact unit’s specifications, installation instructions and energy information. Record distances to property lines rather than estimating from a fence. When a product or location changes, update the package before installation so earlier approvals are not attached to a different proposal.
Show the equipment footprint and its relationship to front, side and rear property lines. Have the actual boundaries confirmed where they are uncertain.
Request the specification sheet, installation manual and applicable sound information for the unit in the quote. Do not use a brochure for a similar size as the final submittal.
Ask who will collect any HOA approval and city documents, and what changes need resubmission. Keep copies with the final equipment order and installation plan.
Before work begins
The August 2024 city checklist calls for a master application, a site plan locating equipment and dimensions to property lines, plus equipment energy and installation information. It also requests the HOA application and approval letter for properties within an HOA.
Confirm current requirements for the chosen system and any separate electrical work. The city’s Building Division directs electrical inspections to Washington L&I. HOA review and public permits serve different purposes, so keep both records where they apply.
No. The city checklist asks for HOA documents when applicable, along with its own application information. Confirm both review paths for the proposed equipment.
Review the substitute’s dimensions, energy and sound information before accepting it. Ask whether any city or HOA documents need updating rather than installing against the previous model’s specifications.
A fence may not mark the legal boundary. Ask how the line is being established and show the required distances from the actual property lines on the site information.
Describe your current system, comfort goals and possible equipment location. Include any HOA requirements so the HVAC estimate can use a consistent model and site proposal from the start.
