Sebastian Estimate Review Notes
Sebastian is a mid-sized Florida market with about 27,087 residents, which usually makes scope clarity more important than comparing one advertised starting price. The place-area data works out to roughly 1,557 residents per square mile, so the estimate should still spell out access, arrival window, and work-area assumptions.
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 |
|---|---|---|
| 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? |
| 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? |
| 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? |
| Permit and code work | Electrical, venting, drain, platform, and disconnect updates may be outside the base equipment price. | Which code or permit items are included in writing? |
