Seattle Estimate Review Notes
Seattle is a major local market with about 780,995 residents, so quotes should separate dispatch timing, labor assumptions, materials, and warranty coverage before comparison. The place-area data works out to roughly 9,298 residents per square mile, so parking, shared walls, access windows, and building rules can affect scheduling.
For HVAC, that means the HVAC service quote should separate diagnosis, equipment sizing, duct or airflow assumptions, permit work, warranty terms, and seasonal scheduling risk.
| Estimate item | Why it matters | Question to ask |
|---|---|---|
| Labor warranty | Manufacturer parts coverage is different from contractor labor coverage. | How long is labor covered, and what maintenance is required? |
| Refrigerant and parts | Older systems can be more expensive to repair when refrigerant or boards are limited. | What refrigerant type and key parts are required? |
| Duct and airflow | Duct restrictions, returns, filters, and static pressure can affect comfort after the repair. | Did the quote include airflow checks and ductwork assumptions? |
| Load calculation | Replacement equipment should be sized to the home, not only matched to the old unit. | Will the estimate include a Manual J or documented load calculation? |
