San Antonio Scope and Scheduling Notes
San Antonio is a major local market with about 1,526,656 residents, so quotes should separate dispatch timing, labor assumptions, materials, and warranty coverage before comparison. The place-area data works out to roughly 3,060 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 |
|---|---|---|
| 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? |
| Labor warranty | Manufacturer parts coverage is different from contractor labor coverage. | How long is labor covered, and what maintenance is required? |
