Sandown Estimate Review Notes
Sandown is handled as a New Hampshire local-service market where the homeowner should verify city limits, county rules, and provider service area before relying on a quote. When place-area or population data is unavailable, the safer comparison is to verify whether the provider prices Sandown as an in-area job or as an extended service-area visit.
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 |
|---|---|---|
| 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? |
| Labor warranty | Manufacturer parts coverage is different from contractor labor coverage. | How long is labor covered, and what maintenance is required? |
| 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? |
